164-552: EERE’s mission is to drive the research, development, demonstration, and deployment of innovative technologies, systems, and practices that will: EERE has been established from several previous agencies within the United States Executive branch following the 1973 energy crisis . It has foundations in the former agencies Federal Energy Administration , the Energy Research and Development Administration ,

328-451: A 300% increase (600 kW) in power generation compared to a buoy without phase adjustments in tests completed in 2024. These devices use multiple floating segments connected to one another. They are oriented perpendicular to incoming waves. A flexing motion is created by swells, and that motion drives hydraulic pumps to generate electricity. The Pelamis Wave Energy Converter is one of the more well-known attenuator concepts, although this

492-487: A First World nation by the 1990s; President Carlos Andrés Pérez of Venezuela likewise launched his Le Gran Venezuela project intended to make Venezuela into a First World nation; and President Yakubu Gowon of Nigeria told his people that henceforward Nigeria's main problem would be "managing abundance". After the oil shock, Nigeria presented itself as the first African nation that would reach First World status and in Lagos

656-788: A Saudi leader since 1953 as he met King Faisal to ask him to end the embargo. Within two week of the embargo being launched, all of the foreign ministers of the nations of the European Economic Community (now the European Union) met in a conference to issue a statement calling for Israel "to end the territorial occupation which has maintained since the conflict of 1967". On December 11, 1973, the Japanese Foreign Minister Masayoshi Ōhira flew in to Riyadh to meet King Faisal for "talks on improving bilateral relations". Shortly afterwards,

820-511: A committee to review the Eisenhower-era quota program. Shultz's committee recommended that the quotas be abolished and replaced with tariffs but Nixon decided to keep the quotas due to vigorous political opposition. Nixon imposed a price ceiling on oil in 1971 as demand for oil was increasing and production was declining, which increased dependence on foreign oil imports as consumption was bolstered by low prices. In 1973, Nixon announced

984-651: A conference in Vienna when it was announced the price for a barrel of oil was to from $ 5 US dollars per barrel to $ 11.65 US dollars per barrel. Faisal was opposed to the price increase, which was largely the work of the Iranian delegation. Over the long term, the oil embargo changed the nature of policy in the West towards increased exploration, alternative energy research, energy conservation and more restrictive monetary policy to better fight inflation. For further details see

1148-511: A device width much smaller than the incoming wavelength λ. Energy is absorbed by radiating a wave with destructive interference to the incoming waves. Buoys use the swells' rise and fall to generate electricity directly via linear generators , generators driven by mechanical linear-to-rotary converters, or hydraulic pumps. Energy extracted from waves may affect the shoreline, implying that sites should remain well offshore. One point absorber design tested at commercial scale by CorPower features

1312-519: A few months. Most scholars agree that the 1967 embargo was ineffective. Although some members of the Organization of Arab Petroleum Exporting Countries (OAPEC) supported the use of oil as a weapon to influence the political outcome of the Arab–Israeli conflict , Saudi Arabia had traditionally been the strongest supporter of separating oil from politics. The Saudis were wary of the tactic due to

1476-727: A fixed amount of gold. After 1971, OPEC was slow to readjust prices to reflect this depreciation. From 1947 to 1967, the dollar price of oil had risen by less than two percent per year. Until the oil shock, the price had also remained fairly stable versus other currencies and commodities. OPEC ministers had not developed institutional mechanisms to update prices in sync with changing market conditions, so their real incomes lagged. The substantial price increases of 1973–1974 largely returned their prices and corresponding incomes to former levels in terms of commodities such as gold. Arab oil producing countries had attempted to use oil as leverage to influence political events on two prior occasions—the first

1640-690: A global leader, courted by elites in both the First World and the Third World. The oil embargo led a sudden interest in the Palestinian issue. Between 1973 and 1981, Saudi Arabia donated a sum worth $ 1 billion US dollars to the Palestine Liberation Organization , which thus had a budget that exceeded that of many Third World nations. On November 8, 1973, Kissinger became the first Secretary of State to meet with

1804-612: A global recession and increased tension between the United States and several of its European allies, who faulted the US for provoking an embargo by providing what many viewed as unconditional assistance to Israel. OAPEC demanded a complete Israeli withdrawal from all territories beyond the 1949 Armistice border . The embargo lasted from October 1973 to March 1974. During a summit in Cairo on November 6, Kissinger asked Sadat what Faisal

1968-402: A long series of trial projects. Attempts to use this energy began in 1890 or earlier, mainly due to its high power density . Just below the ocean's water surface the wave energy flow, in time-average, is typically five times denser than the wind energy flow 20 m above the sea surface, and 10 to 30 times denser than the solar energy flow. In 2000 the world's first commercial wave power device,

2132-454: A negative spring that improves performance and protects the buoy in very large waves. It also has an internal pneumatic cylinder that keeps the buoy at a fixed distance from the seabed regardless of the state of the tide. Under normal operating conditions, the buoy bobs up and down at double the wave amplitude by adjusting the phase of its movements. It rises with a slight delay from the wave, which allows it to extract more energy. The firm claimed

2296-566: A plan to invade Abu Dhabi , Kuwait, and Saudi Arabia. Kissinger publicly threatened "countermeasures" in a Nov 21st, 1973 press conference if the embargo was not lifted, and the Saudis responded with threatening further oil cuts and to burn their oil fields if the US military invaded. After the CIA confirmed these threats, Kissinger gave up military intervention and decided that dealing with Israel's troop withdrawals and settled on diplomatic solutions to

2460-487: A plane wave progressing along the x-axis direction. Oscillatory motion is highest at the surface and diminishes exponentially with depth. However, for standing waves ( clapotis ) near a reflecting coast, wave energy is also present as pressure oscillations at great depth, producing microseisms . Pressure fluctuations at greater depth are too small to be interesting for wave power conversion. The behavior of Airy waves offers two interesting regimes: water deeper than half

2624-493: A series of stately modernist buildings were erected as appropriate for a nation that saw itself as the leader of all black Africa. Much of the oil wealth in Nigeria was stolen by corrupt politicians. However, at least some of Nigeria's new oil wealth went to rebuild the areas devastated by the civil war of 1967-1970 and to address the complaints that too much of Nigeria's oil wealth went to the federal government in Lagos instead of

2788-457: A sign of the pro-Israeli slant of American foreign policy. Faisal also felt insulted that Nixon had just promised Saqqaf a "honorable" peace the day before he submitted the request to Congress for some $ 2.2 billion worth of arms for Israel, which he saw as an act of duplicity on Nixon's part. Faisal had been opposed to a total embargo and only agreed to the 5% cut on October 17 under pressure from other Arab states. Faisal felt his efforts on behalf

2952-554: A single one of its stated objectives. The ceasefire which the USA and the USSR together imposed two days later upon Israel, Syria and Egypt would have been imposed in any case; Israel ended the October war, thanks to US aid, better equipped militarily than she had ever been before, and Faisal's ambition to shrink Israel back inside her pre-1949 boundaries remains unfulfilled to this day. Nor did

3116-501: Is a competition held every other year where collegiate teams design, build, and operate solar-powered houses. The competition winner is the team that best blends affordability, consumer appeal, and design with optimal energy production and maximum efficiency. These homes are judged in 10 contests. In the EcoCAR 3 challenge, 16 university teams redesign a Chevrolet Camaro to reduce its environmental impact without reducing its performance. It

3772-603: Is made up of two programs focused on state and local governments and two teams that develop and deliver targeted technical assistance and strategic initiatives to state and local governments. EERE manages the Energy Saver website that promotes energy-efficient technologies for heating, cooling, and weatherizing buildings and lists tips for saving electricity and fuel. The Office of EERE sponsors several activities aimed at public outreach and engagement in energy efficiency and renewable energy technologies. The Solar Decathlon

3936-418: Is no longer being developed. These devices typically have one end fixed to a structure or the seabed while the other end is free to move. Energy is collected from the relative motion of the body compared to the fixed point. Converters often come in the form of floats, flaps, or membranes. Some designs incorporate parabolic reflectors to focus energy at the point of capture. These systems capture energy from

4100-492: Is one of the primary forums for helping state and local governments implement cost-effective and productive energy systems for American homes, communities, businesses, and industries. The program's mission is to enable strategic investments in energy efficiency and renewable energy technologies and innovative practices across the U.S. by a wide range of government, community and business stakeholders, in partnership with state and local organizations and community-based nonprofits. WIP

4264-578: Is sponsored by DOE and General Motors and managed by Argonne National Laboratory. The Race to Zero Student Design Competition teaches college students about the building science field by challenging them to design zero energy ready homes. In the BioenergizeME Infographic Challenge, students in grades 9-12 use technology to research, interpret, apply, and then design an infographic that responds to one of four cross-curricular bioenergy topics. The Collegiate Wind Competition

4428-584: Is subject to many technical limitations. These limitations stem from the complex and dynamic nature of ocean waves, which require robust and efficient technology to capture the energy. Challenges include designing and building wave energy devices that can withstand the corrosive effects of saltwater, harsh weather conditions, and extreme wave forces. Additionally, optimizing the performance and efficiency of wave energy converters, such as oscillating water column (OWC) devices, point absorbers, and overtopping devices, requires overcoming engineering complexities related to

4592-438: Is the fluid velocity, p {\textstyle p} is the pressure , ρ {\textstyle \rho } the density , ν {\textstyle \nu } the viscosity , and F ext → {\textstyle {\vec {F_{\text{ext}}}}} the net external force on each fluid particle (typically gravity ). Under typical conditions, however,

4756-480: The "drain America first" policy. Some scholars believe the policy contributed to the decline of domestic US oil production in the early 1970s. The cheapness of oil compared with coal led to the decline of the coal industry. In 1951, 51% of America's energy came from coal, and by 1973, only 19% of America's industry was coal-based. When Richard Nixon became president in 1969, he assigned George Shultz to head

4920-650: The Bar Lev Line in the Sinai Peninsula and Syria launched an offensive in the Golan Heights , both of which had been occupied by Israel during the 1967 Six-Day War . The war began during the height of the Watergate scandal and Nixon largely let Kissinger manage foreign policy as he was distracted by the scandal. On 8 October 1973, Faisal told two Egyptian envoys: "You have made us all proud. In

5740-514: The United States Department of Energy . 1973 energy crisis In October 1973, the Organization of Arab Petroleum Exporting Countries (OAPEC) announced that it was implementing a total oil embargo against countries that had supported Israel at any point during the 1973 Yom Kippur War , which began after Egypt and Syria launched a large-scale surprise attack in an ultimately unsuccessful attempt to recover

5904-403: The mean energy density per unit area of gravity waves on the water surface is proportional to the wave height squared, according to linear wave theory: where E is the mean wave energy density per unit horizontal area (J/m ), the sum of kinetic and potential energy density per unit horizontal area. The potential energy density is equal to the kinetic energy, both contributing half to

6068-401: The "Energy crisis" series by Facts on File. The effects of the embargo were immediate. OPEC forced oil companies to increase payments drastically. The price of oil quadrupled by 1974 from US$ 3 to nearly US$ 12 per 42 gallon barrel ($ 75 per cubic meter), equivalent in 2018 dollars to a price rise from $ 17 to $ 61 per barrel. Saudi Arabia had 25% of the world's oil, but only 4% of the oil used in

6232-535: The "oil weapon". It came in the form of an embargo and production cutbacks from the Arab states. The weapon was aimed at the United States, Great Britain, Canada, Japan and the Netherlands. These target governments perceived that the intent was to push them towards a more pro-Arab position. Production was eventually cut by 25%. However, the affected countries did not undertake dramatic policy changes. The risk that

6396-508: The "peace of the brave" (i.e. a victorious leader being magnanimous to his defeated opponents) meant there was a possibility that Sadat at least would make peace with Israel provided that the war ended in such a way that Egypt was not perceived to be defeated. Likewise, Kissinger regarded Meir as being rather arrogant and believed that an armistice that ended the war in a manner that was not an unambiguous Israeli victory would make her more humble. As both Syria and Egypt lost much equipment during

6560-421: The $ 850 million worth of arms requested sent a request to Congress for some $ 2.2 billion worth of arms to Israel, which was promptly approved. Nixon, whose administration was being badly battered by the Watergate scandal, felt that a bold foreign policy move might resuscitate his administration. Nixon later boasted in his memoirs that the U.S. Air Force flew more sorties to Israel in October 1973 than it had during

6724-702: The 1973 "oil price shock" and the accompanying 1973–74 stock market crash as the first discrete event since the Great Depression to have a persistent effect on the US economy. The embargo had a negative influence on the US economy by causing immediate demands to address the threats to U.S. energy security. On an international level, the price increases changed competitive positions in many industries, such as automobiles. Macroeconomic problems consisted of both inflationary and deflationary impacts. The embargo left oil companies searching for new ways to increase oil supplies, even in rugged terrain such as

6888-724: The Algerian state to end many of its more generous social policies between 1986 and 1988, leading to an unemployment rate of 30% by 1988 along with the knowledge that the FLN regime had stolen millions. In the aftermath of the October riots, President Chadli Bendjedid began a transition to democracy. The first free elections in Algeria in January 1992 were won by the Islamist FIS, which led to a military coup and an outbreak of civil war that

7052-558: The American nuclear industry as a way to achieve "energy independence" from the Middle East. On 7 November 1973, Nixon in an address to Congress called for Project Independence to make the United States self-sufficient in energy by 1980, which called for a massive investment in the nuclear industry. Nixon seems to have assumed that nuclear energy was economical, and was encouraged by the faddish enthusiasm of many officials who more on

7216-427: The American oil imports came from the Middle East. Throughout the 1960s, the price for a barrel of oil remained at $ 1.80, meaning that with the effects of inflation considered the price of oil in real terms got progressively lower and lower throughout the decade with Americans paying less for oil in 1969 than they had in 1959. Even after a price for a barrel of oil rose to $ 2.00 in 1971, adjusted for inflation, people in

7380-464: The Americans simply imported more oil from nations that were not part of the embargo such as Iran, but the 400% increase in the price of oil caused by the embargo did damage the American economy. A number of nations such as Venezuela, Nigeria, Iran and Iraq increased their oil production during the embargo, but just sold their oil at a higher price. The leader who pushed the most for higher oil prices

7544-497: The Arab oil embargo of 1973–74 that for people in the West life suddenly become "slower, darker and chiller" as gasoline was rationed, the lights were turned off in Times Square, the "gas guzzler" automobiles suddenly stopped selling, speed limits became common and restrictions were placed on weekend driving in a bid to conserve fuel. As the American automobile industry specialized in producing heavy "gas guzzler" vehicles, there

7708-855: The Arctic. Finding oil and developing new fields usually required five to 10 years before significant production. The average US retail price of a gallon of regular gasoline rose 43% from 38.5¢ in May 1973 to 55.1¢ in June 1974. State governments asked citizens not to put up Christmas lights. Oregon banned Christmas and commercial lighting altogether. Politicians called for a national gasoline rationing program. Nixon asked gasoline retailers to voluntarily not sell gasoline on Saturday nights or Sundays; 90% of gas station owners complied, which produced long lines of motorists wanting to fill up their cars while they still could. The "oil shock" provided considerable impetus to

7872-600: The Berlin Airlift of 1948–49, flying in a gargantuan quantity of arms, though he also admitted that by the time the arms lift had begun, the Israelis had already "turned the tide of battle" in their favor, making the arms lift irrelevant to the outcome of the war. In an interview with the British historian Robert Lacey in 1981, Kissinger later admitted about the arms lift to Israel: "I made a mistake. In retrospect it

8036-615: The Edinburgh Duck. In small-scale tests, the Duck's curved cam -like body can stop 90% of wave motion and can convert 90% of that to electricity, giving 81% efficiency. In the 1980s, several other first-generation prototypes were tested, but as oil prices ebbed, wave-energy funding shrank. Climate change later reenergized the field. The world's first wave energy test facility was established in Orkney , Scotland in 2003 to kick-start

8200-683: The Egyptian Sinai Peninsula , which resulted in Egypt closing the Suez Canal for eight years . Following the Yom Kippur War , the canal was cleared in 1974 and opened again in 1975. OAPEC countries cut production of oil and placed an embargo on oil exports to the United States after Richard Nixon requested $ 2.2 billion to support Israel's war effort. Nevertheless, the embargo lasted only until January 1974, though

8364-609: The Energy Resource Council, and the Atomic Energy Commission , all established prior to the establishment of Department of Energy (DOE) in 1977 ( Pub. L.   95–91 , 91  Stat.   565 , enacted August 4, 1977 ). The 1978 National Energy Act consolidated several of the former agencies into the DOE and created an office that focused on energy efficiency and renewable fuels. Since 1978,

8528-645: The French foreign minister Michel Jobert arrived to sign an agreement that provided oil for France for the next twenty years. On January 24, 1974, as the Shah of Iran, Mohammad Reza Pahlavi , was coming off the ski slopes of St. Moritz , he was met by the British Chancellor of Exchequer, Anthony Barber , and the Trade Secretary, Peter Walker . In a role-reversal, Barber and Walker paid homage to

Teams of two to three members research data, interpret information, and design an infographic that tells a compelling story about the future of geothermal energy. The Hydrogen Student Design Contest "challenges undergraduate and graduate students worldwide to apply design, engineering, economic, environmental science, business and marketing skills to

8856-549: The Grand Mosque and the surviving "renegades" as the rebels were labelled were executed. Likewise, the perception that that most of the wealth being generated by the now higher price of oil was being stolen by a corrupt Shah along with the unfulfilled promises of the "Great Civilization" project played a major role in causing the Iranian Revolution of 197–1979 that toppled the Shah and led to the establishment of

9020-435: The Iranian delegation left Kuwait City as the Shah of Iran was only interested in higher oil prices. The Oil Minister of Iraq, Sa'dun Hammadi demanded the "total nationalization" of all assets of American oil companies in the Middle East, the withdrawal of all Arab funds from the United States and for all Arab states to break diplomatic relations with the United States. The Libyan Oil Minister, Izz al-Din al-Mabruk, called for

9184-786: The Iraqi and Libyan demands for an embargo as Yemani maintained that forcing through an increase in the price of oil was the best way to influence the United States. Hammadi and the rest of the Iraqi delegation left in a huff as Yemani had won over the majority of the delegations to the Saudi viewpoint. The statement issued after midnight at the Sheraton Hotel was handwritten and reflecting the tense talk had several paragraphs crossed out while other paragraphs were written in by different hands. On October 17, Arab oil producers cut production by 5% and instituted an oil embargo against Israel's allies:

9348-551: The Islamic Republic of Iran in February 1979. In Algeria, the "oil shock" led to the establishment of a welfare state where none had existed previously. The lower oil prices of the 1980s along with cutbacks and the belief that the FLN regime was corrupt helped cause the riots of October 1988 against the FLN regime that killed at least 500 people. The riots were largely caused by the fact that the low oil prices had forced

9512-446: The Middle East could become another superpower confrontation with the USSR was of more concern to Washington than oil. Further, interest groups and government agencies more worried about energy were no match for Kissinger's dominance. In the US production, distribution and price disruptions "have been held responsible for recessions, periods of excessive inflation, reduced productivity, and lower economic growth." Some researchers regard

9676-538: The Middle East. In the early 1960s Libya , Indonesia and Qatar joined OPEC. OPEC was generally regarded as ineffective until political turbulence in Libya and Iraq strengthened their position in 1970. Additionally, increasing Soviet influence provided oil producing countries with alternative means of transporting oil to markets. Under the Tehran Price Agreement of 1971 , signed on February 14,

9840-778: The October War more in terms of the Cold War rather than Middle Eastern politics, both seeing the Soviet arms lifts to Egypt and Syria as a Soviet power play that required an American answer. On October 12, 1973, US president Richard Nixon authorized Operation Nickel Grass , a strategic airlift to deliver weapons and supplies to Israel in order to replace its materiel losses, after the Soviet Union began sending arms to Syria and Egypt. The first American weapons to Israel arrived only on 15 October 1973, and despite Nixon's orders

A number of families engaged in the Saudi construction industry such as the Juffali, Alireza, al-Khasshoggi and the bin Laden families all become very wealthy as a result of the construction boom. The period after

10332-481: The Shah, who promised them that his nation would sell the United Kingdom 5 million tons of oil in exchange for some £100 million of British goods to aid his plans to industrialize Iran. Saudi Arabia experienced an upsurge of prosperity and affluence after the oil embargo whose consequences horrified King Faisal. Faisal who was devoted to a harsh puritanical strain of Sunni Islam known in the West as Wahhabism

10496-488: The Soviet military personnel in Egypt in a signal that he wanted better relations with the United States. Kissinger was taken completely by surprise by Sadat's move, saying: "Why has he done me this favor? Why didn't he demand all sorts of concessions first?" Sadat expected as a reward that the United States would respond by pressuring Israel to return the Sinai to Egypt, but after his anti-Soviet move prompted no response from

10660-674: The Suez War. If the United States had done the same after 1967, we would not have witnessed the this deterioration... Before the Jewish State was established, there existed nothing to harm good relations between Arabs and Jews. There were many Jews in Arab countries. When the Jews were persecuted in Spain, Arabs protected them. When the Romans drove the Jews out, Arabs protected them. At Yalta, it

10824-400: The United States forced prices to raise, which in turn led prices to rise everywhere all over the world as oil producers that had not joined the embargo such as Iran, Venezuela, Libya and Iraq demanded higher prices in Japan and Europe as an initiative to ship oil to those places instead of the United States, thus settling off a worldwide inflationary spiral. The only European nations subject to

10988-419: The United States in 1973 came from the kingdom. However, Saudi Arabia plays an over-sized role within the Arab world, and as a Beirut oil consultant noted in 1974: "If Saudi Arabia moves from A to B, then every other oil producer must move at least as far, if not to C." In 1973, about 25% of the oil used in the United States came from Arab countries. The mere shortage of oil caused by the Arab oil embargo within

11152-517: The United States were not being appreciated in Washington, which increased his fury at Nixon. Saudi Arabia only consented to the embargo after Nixon's promise of $ 2.2 billion in military aid to Israel. On the afternoon of October 19, 1973, Faisal was in his office when he learned about the United States sending $ 2.2 billion worth of weapons to Israel, and discussed the issue with two of his closest advisers, Abdullah ibn Abdul Rahman and Rashad Pharaon. The king called Yamani at about 8 pm, and told him he

11316-469: The United States were significantly higher than the global average. After it was implemented, the embargo caused an oil crisis, or "shock", with many short- and long-term effects on the global economy as well as on global politics. The 1973 embargo later came to be referred to as the "first oil shock" vis-à-vis the "second oil shock" that was the 1979 oil crisis , brought upon by the Iranian Revolution . Ever since Israel declared independence in 1948 there

11480-503: The United States, by November 1972 Sadat moved again closer to the Soviet Union, buying a massive amount of Soviet arms for a war he planned to launch against Israel in 1973. For Sadat, cost was no object as the money to buy Soviet arms came from Saudi Arabia. At the same time, Faisal promised Sadat that if it should come to war, Saudi Arabia would embargo oil to the West. In April 1973, the Saudi Oil Minister Ahmed Zaki Yamani visited Washington to meet Kissinger and told him that King Faisal

11644-413: The United States, the Netherlands, Rhodesia , South Africa, and Portugal. On October 17–19, 1973, the Saudi Foreign Minister, Omar Al Saqqaf , visited Washington together with the foreign ministers of Algeria, Kuwait and Morocco to warn that there was a real possibility of an oil embargo being imposed. Saqqaf complained to King Faisal that Nixon seemed more interested in a dispute about "a burglary" (i.e.

11808-468: The Watergate scandal) than about the October War. During a press conference, an American reporter mocked the threat, contemptuously saying the Saudis "could drink their oil", leading Saqqaf to reply in anger "All right, we will!". Joined by the foreign ministers of Algeria, Kuwait and Morocco, Saqqaf met with Nixon in the Oval Office who promised him that the United States would mediate a settlement to

11972-518: The Western nations were paying less for oil in 1971 than they had in 1958. The extremely low price of oil served as the basis for the " long summer " of prosperity and mass affluence that began in 1945. The Organization of Petroleum Exporting Countries (OPEC), was founded by five oil producing countries at a Baghdad conference on September 14, 1960. The five founding members of OPEC were Venezuela , Iraq , Saudi Arabia , Iran and Kuwait . OPEC

12136-559: The availability of oil from non-Arab oil producing countries, and in the decades leading up to the crisis, the region's conservative monarchies had grown dependent on Western support to ensure their continued survival as Nasserism gained traction. On the other hand, Algeria, Iraq and Libya had strongly supported the use of oil as a weapon in the conflict. Arab newspapers like the Egyptian Al-Ahram , Lebanese An-Nahar and Iraqi Al-Thawra had historically been supportive of

12300-510: The basis of faith than rationality saw nuclear energy as the technology of the future. By the late 1960s, a lively environmentalist movement had emerged in the United States, and the Project Independence nuclear program was the subject of much debate in both the media and Congress. The ensuing debates revealed that many of the claims made for nuclear power vast underestimated the true costs of nuclear reactors. Equally problematic

12464-414: The behavior of waves in the various regimes: In deep water where the water depth is larger than half the wavelength , the wave energy flux is with P the wave energy flux per unit of wave-crest length, H m0 the significant wave height , T e the wave energy period , ρ the water density and g the acceleration by gravity . The above formula states that wave power is proportional to

12628-992: The boundary constraints (and k {\displaystyle k} ). Specifically, A ( z ) = g H 2 ω cosh ⁡ ( k ( z + h ) ) cosh ⁡ ( k h ) ω = g k tanh ⁡ ( k h ) . {\displaystyle {\begin{aligned}&A(z)={gH \over 2\omega }{\cosh(k(z+h)) \over \cosh(kh)}\\&\omega =gk\tanh(kh){\text{.}}\end{aligned}}} The surface elevation η {\displaystyle \eta } can then be simply derived as η = − 1 g ∂ ϕ ∂ t = H 2 cos ⁡ ( k x − ω t ) : {\displaystyle \eta =-{1 \over g}{\partial \phi \over \partial t}={H \over 2}\cos(kx-\omega t){\text{:}}}

12792-464: The cartoons as a sort of shorthand for insatiable greed. Wave energy Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation , water desalination , or pumping water. A machine that exploits wave power is a wave energy converter ( WEC ). Waves are generated primarily by wind passing over the sea's surface and also by tidal forces, temperature variations, and other factors. As long as

12956-403: The case for nuclear power in the ensuring debates. By 1989, only 18% of American energy came from nuclear power plants, which was a faction of what Project Independence had envisioned in 1973. The "oil shock" led to anti-Arab feelings becoming common. Cartoons published in American newspapers during the "oil shock" depicted Arabs as disgusting, ugly, obese, corrupt and greedy. In the cartoons,

13120-453: The demand being made that the government find some other community to store the rods. Many of the nuclear reactors ordered in 1973 were cancelled due to the horrendous cost overruns while over 100 nuclear plants were shut down as uneconomical over the next 10 years. Unlike nations that tried to use nuclear power as a way for "energy independence" such as France and Sweden, the United States had substantial reserves of its own oil, which weakened

13284-417: The development of a wave and tidal energy industry. The European Marine Energy Centre(EMEC) has supported the deployment of more wave and tidal energy devices than any other single site. Subsequent to its establishment test facilities occurred also in many other countries around the world, providing services and infrastructure for device testing. The £10 million Saltire prize challenge was to be awarded to

13448-462: The difference in pressure at different locations below a wave to produce a pressure difference within a closed power take-off hydraulic system. This pressure difference is usually used to produce flow, which drives a turbine and electrical generator. Submerged pressure differential converters typically use flexible membranes as the working surface between the water and the power take-off. Membranes are pliant and low mass, which can strengthen coupling with

13612-460: The displacement of commercial and recreational fishermen, and may present navigation hazards. Supporting infrastructure, such as grid connections, must be provided. Commercial WECs have not always been successful. In 2019, for example, Seabased Industries AB in Sweden was liquidated due to "extensive challenges in recent years, both practical and financial". Current wave power generation technology

13776-483: The distance below the free surface. This means that by optimizing depth, protection from extreme loads and access to wave energy can be balanced. Floating in-air converters potentially offer increased reliability because the device is located above the water, which also eases inspection and maintenance. Examples of different concepts of floating in-air converters include: In early 2024, a fully submerged wave energy converter using point absorber-type wave energy technology

13940-550: The dollar inconvertible to gold directly, except on the open market, and was soon dubbed the Nixon Shock , leading eventually to the collapse of the Bretton Woods system in 1976. Because oil was priced in dollars, oil producers' real income decreased when the dollar started to float free of the old link to gold. In September 1971, OPEC issued a joint communiqué stating that from then on, they would price oil in terms of

14104-422: The dynamic and variable nature of waves. Furthermore, developing effective mooring and anchoring systems to keep wave energy devices in place in the harsh ocean environment, and developing reliable and efficient power take-off mechanisms to convert the captured wave energy into electricity, are also technical challenges in wave power generation. As the wave energy dissipation by a submerged flexible mound breakwater

14268-417: The embargo of 1973–1974 had caused about 500,000 Americans to lose their jobs and caused a GNP loss between $ 10 billion–$ 20 billion. This price increase had a dramatic effect on oil exporting nations, for the countries of the Middle East who had long been dominated by the industrial powers were seen to have taken control of a vital commodity. The oil-exporting nations began to accumulate vast wealth. Some of

14432-618: The embargo was a failure because the countries that were targeted by the embargo did not change their policies on the Arab–Israeli conflict. Licklieder believed that any long term changes were caused by the OPEC increase in the posted price of oil, and not the OAPEC embargo. Daniel Yergin , on the other hand, has said that the embargo "remade the international economy". Lacey wrote: "King Faisal's momentous oil embargo of 20 October 1973 did not achieve

14596-534: The embargo. The crisis eased when the embargo was lifted in March 1974 after negotiations at the Washington Oil Summit, but the effects lingered throughout the 1970s. The dollar price of energy increased again the following year, amid the weakening competitive position of the dollar in world markets. The Arab oil embargo ended the long period of prosperity in the West that had begun in 1945, throwing

14760-407: The end of the quota system. Between 1970 and 1973 US imports of crude oil had nearly doubled, reaching 6.2 million barrels per day in 1973. Until 1973, an abundance of oil supply had kept the market price of oil lower than the posted price. In 1970, American oil production peaked and the United States began to import more and more oil as oil imports rose by 52% between 1969 and 1972. By 1972, 83% of

14924-401: The energy of the waves). A given wind speed has a matching practical limit over which time or distance do not increase wave size. At this limit the waves are said to be "fully developed". In general, larger waves are more powerful but wave power is also determined by wavelength , water density , water depth and acceleration of gravity. Wave energy converters (WECs) are generally categorized by

15088-426: The entire water column. Overtopping devices are long structures that use wave velocity to fill a reservoir to a greater water level than the surrounding ocean. The potential energy in the reservoir height is captured with low-head turbines. Devices can be on- or offshore. Submerged pressure differential based converters use flexible (typically reinforced rubber) membranes to extract wave energy. These converters use

15252-454: The fact that The Protocols had been exposed as a forgery in 1921. Initially, Secretary of Defense James Schlesinger suggested to Kissinger that the USA invade Saudi Arabia and another Arab countries and seize their oil fields. Kissinger stated in a private state department meeting that it's “ridiculous that the civilized world is held up by 8 million savages... Can’t we overthrow one of the sheikhs just to show that we can do it?” They formed

15416-507: The fighting, the Soviet Union began to fly new equipment in starting on October 12, and the Soviet flights to Syria and Egypt were recorded by the British radar stations in Cyprus. Though the Soviets were flying in an average of 60 flights per day, exaggerated accounts appeared in Western newspapers speaking of "one hundred flights per day". At this point, both Nixon and Kissinger began to see

15580-470: The fighting. So we agreed to cut back production by just 5 percent per month. A full embargo, we agreed, was something we would implement only if we felt that things were absolutely hopeless". At an OPEC summit at the Sheraton Hotel in Kuwait City on October 16, 1973, it was announced the price of oil would go from $ 3.01 U.S. dollars per barrel to $ 5.12 per barrel. After agreeing to the price increase,

15744-425: The first to be able to generate 100 GWh from wave power over a continuous two-year period by 2017 (about 5.7 MW average). The prize was never awarded. A 2017 study by Strathclyde University and Imperial College focused on the failure to develop "market ready" wave energy devices – despite a UK government investment of over £200 million over 15 years. Public bodies have continued and in many countries stepped up

15908-530: The followers of the Mahdi (a messianic figure said to appear at the dawn of every Muslim century to strike down the enemies of Islam). The leader of the uprising, Juhayman al-Otaybi , read out a list of grievances as he accused the House of Saud of being corrupt and degenerate as he listed by name a number of Saudi princes who were engaged in dubious business dealings and/or who drank alcohol. The Saudi Army recaptured

16236-518: The gravitational pull of the Sun and Moon. However, wave power and tidal power are not fundamentally distinct and have significant cross-over in technology and implementation. Other forces can create currents , including breaking waves , wind , the Coriolis effect , cabbeling , and temperature and salinity differences. As of 2023, wave power is not widely employed for commercial applications, after

16400-528: The hydrogen and fuel cell industries." In the Georgetown University Energy Prize competition, cities and counties with populations between 5,000 and 250,000 compete for a multi-year $ 5 million prize for demonstrating energy use reduction over a two-year period. The Cleantech University Prize provides competitive funding for business development and commercialization training to clean energy entrepreneurs. The Wave Energy Prize

16564-477: The income was dispensed in the form of aid to other underdeveloped nations whose economies had been caught between higher oil prices and lower prices for their own export commodities, amid shrinking Western demand. Much went for arms purchases that exacerbated political tensions, particularly in the Middle East. Saudi Arabia spent over 100 billion dollars in the ensuing decades for helping spread its fundamentalist interpretation of Islam, known as Wahhabism , throughout

16728-403: The king end the oil embargo after Sadat, whom he trusted, reported to him that the United States was being more "evenhanded" and after Kissinger had promised to sell Saudi Arabia weapons that it had previously denied under the grounds that they might be used against Israel. More importantly, Saudi Arabia had billions of dollars invested in Western banks, and the massive bout of inflation set off by

16892-403: The largest offshore sea states have significant wave height of about 15 meters and energy period of about 15 seconds. According to the above formula, such waves carry about 1.7 MW of power across each meter of wavefront. An effective wave power device captures a significant portion of the wave energy flux. As a result, wave heights diminish in the region behind the device. In a sea state ,

17056-410: The long hooked Semitic noses that had traditionally been featured in anti-Jewish cartoons were applied to the Arab sheiks as a way to illustrate their supposed greed. American public opinion did not see the use of the "oil weapon" as due to politics, and tended to explain the embargo as only due to the excessive greed of King Faisal and the other Arab leaders, hence the use of the hooked Semitic nose in

17220-421: The method, by location and by the power take-off system. Locations are shoreline, nearshore and offshore. Types of power take-off include: hydraulic ram , elastomeric hose pump , pump-to-shore, hydroelectric turbine , air turbine, and linear electrical generator . The four most common approaches are: This device floats on the surface, held in place by cables connected to the seabed. The point-absorber has

17384-521: The most potential for wave power include the western seaboard of Europe, the northern coast of the UK, and the Pacific coastlines of North and South America, Southern Africa, Australia, and New Zealand. The north and south temperate zones have the best sites for capturing wave power. The prevailing westerlies in these zones blow strongest in winter. The National Renewable Energy Laboratory (NREL) estimated

17548-771: The movement of waves is described by Airy wave theory , which posits that In situations relevant for energy harvesting from ocean waves these assumptions are usually valid. The first condition implies that the motion can be described by a velocity potential ϕ ( t , x , y , z ) {\textstyle \phi (t,x,y,z)} : ∇ → × u → = 0 → ⇔ u → = ∇ → ϕ , {\displaystyle {{\vec {\nabla }}\times {\vec {u}}={\vec {0}}}\Leftrightarrow {{\vec {u}}={\vec {\nabla }}\phi }{\text{,}}} which must satisfy

17712-579: The nationalization of all the assets of all Western oil companies in the Middle East. The news about the war on October 16 was grim from the Arab viewpoint with the Syrians steadily being pushed back while Israelis had opened a counter-offensive against the Egyptians and crossed the Great Bitter Lake. The Saudi delegation led by Yemani, supported by the Algerian delegation, fought hard against

17876-586: The number of American planes flying into Tel Aviv were initially limited. After the first week of the war, the Israelis had halted the Syrian offensive in the Golan Heights and were pushing back the Syrians back towards Damascus, but along the Suez canal, there was heavy fighting with the Egyptians holding their own. Yamani stated in a 1981 interview: "The king still wanted to give America a chance to stay out of

18040-446: The odds of making peace along the lines of United Nations Security Council Resolution 242 calling for a "land for peace" deal if an armistice was signed with Egypt and Syria gaining some territory in the Sinai and the Golan Heights respectively. Nixon had ordered an arms lift to Israel on 12 October 1973, but Kissinger used the excuse of bureaucratic delays to limit the amount of weapons and ammunition sent to Israel. The Arab concept of

18204-504: The office has been renamed several times to reflect its changing scope, including the following: The current name, the Office of Energy Efficiency and Renewable Energy, was adopted in 1993. The Assistant Secretary of Energy Efficiency and Renewable Energy oversees EERE's three technology sectors: Within these sectors are 11 technology offices and programs that support research, development, and outreach efforts [EERE Organization Chart]. EERE also includes corporate support functions such as

18368-494: The oil embargo was a threat to this fortune as inflation eroded the value of the money, giving Faisal a vested interest in helping to contain the damage he himself inflicted on the economies of the West. Since Israeli forces did not withdraw to the 1949 Armistice Line, the majority of scholars believe that the embargo was a failure. Roy Licklieder, in his 1988 book Political Power and the Arab Oil Weapon , concluded that

18532-538: The oil embargo were the Netherlands (because the Dutch Foreign Minister Max van der Stoel was strongly pro-Israeli) and Portugal (in a support of show for the independence movements in Portugal's African colonies), but the shortage of oil in the United States led to sharp price rises in all of the European nations. The embargo itself did not cause much economic difficulty in the United States as

18696-474: The oil embargo, oil exports from the Middle East to the West were down by 60–70% by November 1973. Japan and the nations of western Europe imported some 75% of their oil from the Near East, and the embargo led to immediate and sharp price raises as Lacey noted that "competing desperately for dwindling supplies, consumers showed themselves willing to pay unparalleled money for their oil". Saudi Arabia had 25% of

18860-530: The oil embargo. On November 7, 1973, Kissinger flew to Riyadh to meet King Faisal and ask him to end the oil embargo in exchange for promising to be "evenhanded" with the Arab-Israeli dispute. As the plane carrying him prepared to land in Riyadh, Kissinger was clearly nervous at the prospect of negotiating with the stern Wahhabi Faisal who had a marked dislike of Jews. Kissinger discovered that King Faisal

19024-423: The oil shock of 1973–1974 is still fondly remembered in Saudi Arabia as the "age of abundance" where nearly everyone had a significant increase in their standard of living. The wealth and corruption generated by the oil shock led to a fundamentalist backlash in Saudi Arabia. On 20 November 1979, Islam's most holiest shrine, the Grand Mosque of Mecca, was seized by a group of fanatics who proclaimed themselves to be

19188-408: The output produced by a device), and is equal to: Due to the dispersion relation for waves under gravity, the group velocity depends on the wavelength λ , or equivalently, on the wave period T . Wave height is determined by wind speed, the length of time the wind has been blowing, fetch (the distance over which the wind excites the waves) and by the bathymetry (which can focus or disperse

19352-552: The past we could not lift our heads up. Now we can". Faisal promised to give to Egypt a quality of aid worth $ 200 million US dollars to assist with the war effort, and stated he was willing to use the "oil weapon" if necessary to support Egypt. Kissinger promised the Israeli Prime Minister Golda Meir the United States would replace its losses in equipment after the war, but sought initially to delay arm shipments to Israel as he believed it would improve

19516-433: The people. In Iran, the Shah who was aware by 1974 that he had developed the cancer that was to ultimately kill him in 1980 pushed very strongly for his "Great Civilization" for rapid modernization not the least because he wanted to see the "Great Civilization" before his death, which explained his grandiose announcements. The new wealth generated by the "oil shock" allowed for Chairman Houari Boumédiène of Algeria to become

19680-405: The posted price of oil was increased and, due to a decline in the value of the US dollar relative to gold, certain anti-inflationary measures were enacted. Because of a severe drain on U.S. gold reserves, leading to higher inflation and lack of confidence in the strength of the dollar, President Nixon issued Executive Order 11615 on August 15, 1971, closing the " gold window ". This action made

19844-567: The price of oil by 400% within a matter of days threw the world's economy into a sharp recession with unemployment mounting and inflation raging came as a profound shock. The end of what the French called the Trente Glorieuses ("Glorious Thirty" [years]) led to a mood of widespread pessimism in the West with the Financial Times running a famous headline in late 1973 saying "The Future will be subject to Delay". Kurt Waldheim,

20008-574: The price of oil remained high afterwards. By 1969, American domestic output of oil was peaking and could not keep pace with increasing demand from vehicles. The U.S. was importing 350 million barrels (56 million cubic metres) per year by the late 1950s, mostly from Venezuela and Canada . Because of transportation costs and tariffs, it never purchased much oil from the Middle East. In 1973, US production had declined to 16% of global output. Eisenhower imposed quotas on foreign oil that would stay in place between 1959 and 1973. Critics called it

20172-1364: The quadratic term ( ∇ → ϕ ) 2 {\textstyle \left({\vec {\nabla }}\phi \right)^{2}} can be neglected, giving the linear Bernoulli equation, ∂ ϕ ∂ t + 1 ρ p + g z = ( const ) . {\displaystyle {\partial \phi \over \partial t}+{1 \over \rho }p+gz=({\text{const}}){\text{.}}} and third Airy assumptions then imply ∂ 2 ϕ ∂ t 2 + g ∂ ϕ ∂ z = 0 ( surface ) ∂ ϕ ∂ z = 0 ∂ 2 ϕ ∂ t 2 + ( seabed ) {\displaystyle {\begin{aligned}&{\partial ^{2}\phi \over \partial t^{2}}+g{\partial \phi \over \partial z}=0\quad \quad \quad ({\text{surface}})\\&{\partial \phi \over \partial z}=0{\phantom {{\partial ^{2}\phi \over \partial t^{2}}+{}}}\,\,\quad \quad \quad ({\text{seabed}})\end{aligned}}} These constraints entirely determine sinusoidal wave solutions of

20336-403: The research and development funding for wave energy during the 2010s. This includes both EU, US and UK where the annual allocation has typically been in the range 5-50 million USD. Combined with private funding, this has led to a large number of ongoing wave energy projects (see List of wave power projects ). Like most fluid motion, the interaction between ocean waves and energy converters

20500-428: The rise and fall of waves. Oscillating water column devices can be located onshore or offshore. Swells compress air in an internal chamber, forcing air through a turbine to create electricity . Significant noise is produced as air flows through the turbines, potentially affecting nearby birds and marine organisms . Marine life could possibly become trapped or entangled within the air chamber. It draws energy from

20664-522: The second summit of Islamic states in Lahore (which, unlike the first summit that Faisal had chaired in 1969, was not boycotted by Iraq and Syria ) where he was acclaimed as a conquering hero who humiliated and humbled the West by wrecking its economy. The prime minister of Pakistan, Zulfikar Ali Bhutto, opened the conference by stating: "The armies of Pakistan are the armies of Islam. We shall enter Jerusalem as brothers-in-arms!" Only on March 18, 1974 did

20828-643: The secretary-general of the United Nations in an address to the General Assembly complained about "the note of helplessness and fatalism creeping into world affairs". The sudden and abrupt end of the "long summer" of prosperity in 1973-1974 played a major role in the pessimistic mood that characterized the culture of the rest of the 1970s. In 1975, a report to Congress from the Federal Energy Administration estimated that

20992-712: The territories that they had lost to Israel during the 1967 Six-Day War . In an effort that was led by Faisal of Saudi Arabia , the initial countries that OAPEC targeted were Canada , Japan , the Netherlands , the United Kingdom , and the United States . This list was later expanded to include Portugal , Rhodesia , and South Africa . In March 1974, OAPEC lifted the embargo, but the price of oil had risen by nearly 300%: from US$ 3 per barrel ($ 19/ m ) to nearly US$ 12 per barrel ($ 75/m ) globally. Prices in

21156-432: The theoretical wave energy potential for various countries. It estimated that the US' potential was equivalent to 1170 TWh per year or almost 1/3 of the country's electricity consumption. The Alaska coastline accounted for ~50% of the total. The technical and economical potential will be lower than the given values for the theoretical potential. Environmental impacts must be addressed. Socio-economic challenges include

21320-502: The use of oil as a weapon. In 1970, President Nasser of Egypt died and was succeeded by Anwar Sadat , a man who believed in the diplomacy of surprise, in engaging in sudden moves to upset the diplomatic equilibrium. Sadat liked to say that his favourite game was backgammon , a game where skill and persistence was rewarded, but was best won by sudden gambles, making an analogy between how he played backgammon and conducted his diplomacy. Under Nasser, Egypt and Saudi Arabia had engaged what

21484-574: The war that would be "peaceful, just and honorable" to both sides. Saqqaf reported to King Faisal that Nixon told him that he ended the Vietnam war on an honorable basis and now intended to end the October war in the same manner. Israel took heavy losses in men and material during the fighting against Egypt and Syria, and on October 18, 1973, Meir requested $ 850 million worth of American arms and equipment to replace its material losses. Nixon decided characteristically to act on an epic scale and instead of

21648-417: The warning that Faisal was considerably tougher, more intelligent and more ruthless than his half-brother Saud whom he had deposed in 1964, and his threats were serious. Kissinger declined to meet the four CEOs. In an assessment done by Kissinger and his staff about the Middle East in the summer of 1973, the repeated statements by Sadat about waging  jihad against Israel were dismissed as empty talk while

21812-478: The warnings from King Faisal were likewise regarded as inconsequential. In September 1973, Nixon fired Rogers as Secretary of State and replaced him with Kissinger. Kissinger was later to state he had not been given enough time to know the Middle East as he settled into the State Department's office at Foggy Bottom as Egypt and Syria attacked Israel on October 6, 1973. On October 6, 1973, Egypt attacked

21976-407: The wave energy density E , as can be expected from the equipartition theorem . The waves propagate on the surface, where crests travel with the phase velocity while the energy is transported horizontally with the group velocity . The mean transport rate of the wave energy through a vertical plane of unit width, parallel to a wave crest, is the energy flux (or wave power, not to be confused with

22140-486: The wave energy period and to the square of the wave height. When the significant wave height is given in metres, and the wave period in seconds, the result is the wave power in kilowatts (kW) per metre of wavefront length. For example, consider moderate ocean swells, in deep water, a few km off a coastline, with a wave height of 3 m and a wave energy period of 8 s. Solving for power produces or 36 kilowatts of power potential per meter of wave crest. In major storms,

22304-465: The wave's energy. Their pliancy allows large changes in the geometry of the working surface, which can be used to tune the converter for specific wave conditions and to protect it from excessive loads in extreme conditions. A submerged converter may be positioned either on the seafloor or in midwater. In both cases, the converter is protected from water impact loads which can occur at the free surface . Wave loads also diminish in non-linear proportion to

22468-476: The wavelength, as is common in the sea and ocean, and shallow water, with wavelengths larger than about twenty times the water depth. Deep waves are dispersionful : Waves of long wavelengths propagate faster and tend to outpace those with shorter wavelengths. Deep-water group velocity is half the phase velocity . Shallow water waves are dispersionless: group velocity is equal to phase velocity, and wavetrains propagate undisturbed. The following table summarizes

22632-401: The waves propagate slower than the wind speed just above, energy is transferred from the wind to the waves. Air pressure differences between the windward and leeward sides of a wave crest and surface friction from the wind cause shear stress and wave growth. Wave power as a descriptive term is different from tidal power , which seeks to primarily capture the energy of the current caused by

22796-448: The way his subjects had been seduced into a consumerist lifestyle, becoming lost in a sense of "melancholia". Faisal's son, Crown Prince Mohammad told Lacey in 1981: "The profligacy, the greed, he felt he could not stem it. He become so bound up in his work, there was almost nothing private of him left". A sign of the changed values was that despite the total ban on alcohol in Saudi Arabia that drinking along with drug use become common with

22960-533: The withholding of the 638,500 barrels of oil which the Saudi Arabia had been selling to America every day for the first 10 months of 1973 ever come, in itself, to jeopardizing the power or diverting the policies of the United States, since it accounted for less than 4 percent of America's daily 17 million barrel consumption. It was the interaction which Faisal's embargo had with other forces that made it so decisive. Arab politics had an immediate multiplier effect". Because every Arab state except for Iraq and Libya joined

23124-468: The world's economy into the steepest economic contraction since the Great Depression. The "long summer" of prosperity in the post-war years had made possible the "swinging sixties" and the related rise of a rebellious youth culture as it was very easy to be hedonist and/or in rebellion against traditional values in a time of unprecedented affluence and prosperity. Lacey wrote about the impact of

23288-452: The world's oil reserves and the embargo imposed on the United States led to shortages of oil in the United States, which set an inflationary spiral as the new high prices for oil in the American market led to sharp increases of the price of oil in nations not subjected to the embargo. When the Iranian state oil company held an auction on December 16, 1973, bids for some $ 17 US dollars per barrel of oil were made. In late December 1973, OPEC held

23452-609: The world, via religious charities such as the al-Haramain Foundation , which often also distributed funds to violent Sunni extremist groups such as Al-Qaeda and the Taliban. The 400% increase in the world oil prices led to extravagant promises being made by the leaders of oil-producing nations. The Shah of Iran told his subjects in a speech in December 1973 that he was launching "Great Civilization" project that would make Iran into

23616-461: The younger members of the House of Saud. James Akins, the American ambassador in Riyadh reported; "the sky over Riyadh is black with vultures with new get-richer-quicker plans under their wings". In 1974, property prices in Riyadh doubled on a weekly basis for the entire year as the prosperity led to a real estate speculation bubble that was often compared to the Klondike gold rush of 1898–1899.

23780-646: Was conflict between Arabs and Israelis in the Middle East , including several wars . The Suez Crisis , also known as the Second Arab–Israeli war, was sparked by Israel's southern port of Eilat being blocked by Egypt , which also nationalized the Suez Canal belonging to French and British investors. As a result of the war, the Suez Canal was closed for several months between 1956 and 1957 . The Six-Day War of 1967 included an Israeli invasion of

23944-480: Was Stalin who said there had to be a Jewish state...Israel is advancing Communist objectives...Among those of the Jewish faith there are those who embrace Zionism...Most of the immigration to Israel is from the Soviet Union...They want to establish a Communist base right in the Middle East...And now, all over the world, the Jews are putting themselves into positions of authority". On February 22, 1974, King Faisal chaired

24108-552: Was a worthy companion to Lê Đức Thọ in terms of stubbornness as the king accused the United States of being biased in favor of Israel, going on in a long rant about the balefulness of "Jewish Communists" in Russia and Israel, and despite all of Kissinger's efforts to charm him, refused to end the oil embargo. Faisal told Kissinger: "The United States used to stand up to aggression-you did that in World War Two and in 1956 during

24272-471: Was an immediate shift on the part of consumers to the lighter and more fuel efficient vehicles produced by the Japanese and West German automobile industries, sending the American automobile industry into decline. The years from 1945 to 1973 had been a period of unprecedented prosperity in the West, a "long summer" that many believed would never end, and its abrupt end in 1973 as the oil embargo which increased

24436-491: Was appalled by the way that his subjects became materialistic, devoted only to conspicuous consumption and greed as they lost interest in Islam. Lacey wrote: "The spiritual dangers of easy affluence distressed him more. His simple gesture of piety and honor seemed to have opened a Pandora's Box that threatened to turn his realm into a parody of all he held dear". In the last two of years of his life, Faisal fell into depression over

24600-500: Was approved in Spain. The converter includes a buoy that is moored to the bottom and situated below the surface, out of sight of people and away from storm waves. Common environmental concerns associated with marine energy include: The Tethys database provides access to scientific literature and general information on the potential environmental effects of ocean current energy. Wave energy's worldwide theoretical potential has been estimated to be greater than 2 TW. Locations with

24764-558: Was becoming more and more unhappy with the United States, saying he wanted America to pressure Israel to return all the lands captured in the Six Day War of 1967. In a later interview, Yamani accused Kissinger of not taking his warning seriously, saying all he did was to ask him not to speak anymore of this threat. Angry at Kissinger, Yamani in an interview with the Washington Post on April 19, 1973, warned that King Faisal

24928-534: Was considering an oil embargo. At the time, the general feeling in Washington was the Saudis were bluffing and nothing would come of their threat to impose an oil embargo. The fact that Faisal's ineffectual half brother King Saud had imposed a cripplingly oil embargo on Britain and France during the Suez War of 1956 was not considered an important precedent. The CEOs of four of America's oil companies had after speaking to Faisal arrived in Washington in May 1973 with

25092-621: Was in 1799, filed in Paris by Pierre-Simon Girard and his son. An early device was constructed around 1910 by Bochaux-Praceique to power his house in Royan , France. It appears that this was the first oscillating water-column type of wave-energy device. From 1855 to 1973 there were 340 patents filed in the UK alone. Modern pursuit of wave energy was pioneered by Yoshio Masuda 's 1940s experiments. He tested various concepts, constructing hundreds of units used to power navigation lights. Among these

25256-600: Was known as the Arab Cold War , but Sadat got along very well with King Faisal of Saudi Arabia , forming an alliance between the most populous Arab state and the wealthiest Arab state. Unlike the secularist Nasser, Sadat was a pious Muslim and he had a strong personal rapport with King Faisal, who was an equally pious Muslim. The man largely in charge of American foreign policy, the National Security Adviser, Henry Kissinger , later admitted that he

25420-561: Was like and was told: "Well, Dr. Henry, he will probably go on with you about Communism and the Jews". King Faisal's two great hatreds were Communism and Zionism as he believed that the Soviet Union and Israel were plotting together against Islam. When King Faisal was shown a translation into Arabic of The Protocols of the Learned Elders of Zion , he instantly believed in the authenticity of The Protocols and therefore talked to anyone who would listen about what he had learned, despite

25584-480: Was needed at the Riyassa Palace immediately. Yamani told the king: "The TV news goes out at nine. If you make a decision now, we can get it announced at once". The king replied "Write this down" and announced he was placing a total embargo on the United States. The embargo was accompanied by gradual monthly production cuts—by December, production had been cut to 25% of September levels. This contributed to

25748-464: Was not the best considered decision we made". The arms lift enraged King Faisal of Saudi Arabia and he retaliated on October 20, 1973, by placing a total embargo on oil shipments to the United States, to be joined by all of the other oil-producing Arab states except Iraq and Libya. Faisal was angry that Israel had only asked for $ 850 million worth of American weapons, and instead received an unsolicited $ 2.2 billion worth of weapons, which he perceived as

25912-545: Was organized after the oil companies slashed the posted price of oil, but the posted price of oil remained consistently higher than the market price of oil between 1961 and 1972. In 1963, the Seven Sisters controlled 86% of the oil produced by OPEC countries, but by 1970 the rise of "independent oil companies" had decreased their share to 77%. The entry of three new oil producers— Algeria , Libya and Nigeria —meant that by 1970, 81 oil companies were doing business in

26076-537: Was so engrossed with the Paris peace talks to end the Vietnam war that he and others in Washington missed the significance of the Egyptian-Saudi alliance. At the same time that Sadat moved closer to Saudi Arabia, he also wanted a rapprochement with the United States and to move Egypt away from its alliance with the Soviet Union. In 1971, the US had information that the Arab states were willing to implement another embargo. In July 1972, Sadat expelled all 16,000 of

26240-606: Was the Suez Crisis in 1956 when the United Kingdom, France and Israel invaded Egypt. During the conflict the Syrians sabotaged both the Trans-Arabian Pipeline and the Iraq–Baniyas pipeline , which disrupted the supply of oil to Western Europe. The second instance was when war broke out between Egypt and Israel in 1967, but despite continued Egyptian and Syrian enmity against Israel, the embargo lasted only

26404-481: Was the Shah of Iran, and the Italian historian Giuliano Garavini has argued that the leader most responsible for the West's economic problems during the "oil shock" was not King Faisal, but rather the Shah. Some of the nations that were classified as "friendly" to the Arab viewpoint in regards to the Arab-Israeli dispute such as France and Belgium were the ones who suffered the most from the worldwide inflation caused by

26568-635: Was the concept of extracting power from the angular motion at the joints of an articulated raft, which Masuda proposed in the 1950s. The oil crisis in 1973 renewed interest in wave energy. Substantial wave-energy development programmes were launched by governments in several countries, in particular in the UK, Norway and Sweden. Researchers re-examined waves' potential to extract energy, notably Stephen Salter , Johannes Falnes , Kjell Budal , Michael E. McCormick , David Evans , Michael French, Nick Newman , and C. C. Mei . Salter's 1974 invention became known as Salter's duck or nodding duck , officially

26732-409: Was the troublesome issue of where to safety store the spent nuclear rods that emitted a toxic level of radioactivity for centuries afterward in an cost-effective manner. The issue of the spent nuclear rods was especially difficult because in a classic case of NIMBYism , communities proved very unwilling to accept a storage place for the inevitable by-product of nuclear power, the spent nuclear rods, with

26896-542: Was to kill hundreds of thousands. OPEC-member states raised the prospect of nationalization of oil company holdings. Most notably, Saudi Arabia nationalized Aramco in 1980 under the leadership of Saudi oil minister Ahmed Zaki Yamani . As other OPEC nations followed suit, the cartel's income soared. Saudi Arabia undertook a series of ambitious five-year development plans. The biggest began in 1980, funded at $ 250 billion. Other cartel members also undertook major economic development programs. Control of oil became known as
