The Energy Tax Act ( Pub. L. 95–618 , 92 Stat. 3174 , enacted November 9, 1978) is a law passed by the U.S. Congress as part of the National Energy Act . The objective of this law was to shift from oil and gas supply toward energy conservation ; thus, to promote fuel efficiency and renewable energy through taxes and tax credits .
103-451: This law gave an income tax credit to private residents who use solar , wind , or geothermal sources of energy. The credit is equal to 30% of the cost of the equipment up to $ 2000, as well as 20% of costs greater than $ 2000, up to a maximum of $ 10,000. There were also tax credits to businesses for renewable energy equipment, amounting to a maximum of 25% of the cost of the equipment. The renewable energy credits of this law were increased by
206-413: A photovoltaic system , or PV system, produces direct current (DC) power which fluctuates with the sunlight's intensity. For practical use this usually requires conversion to alternating current (AC), through the use of inverters . Multiple solar cells are connected inside panels. Panels are wired together to form arrays, then tied to an inverter, which produces power at the desired voltage, and for AC,
309-541: A 4 L I6 cylinder version was available paired to a five-speed manual transmission. The BJ7250 uses the same 2.5 L engine as the BJ2021, but includes a five-speed manual gearbox instead of a speed-speed unit. The BJ2021 is 4290 millimeters in length, 1800 millimeters in width, and 1620 millimeters in height as well as using a 2580 millimeter wheelbase. The BJ7250, however, is 90 millimeters shorter in length, 40 millimeters shorter in width and 10 millimeters taller and
412-621: A five-slot grille, along with six-lug wheels. Production ended in 2014. All Chinese specification Jeeps had a five-speed manual gearbox as standard. Chinese car manufacturer Shuanghuan Auto , who are known for their copy of the Toyota Land Cruiser Prado (J120) front end, BMW X5 (E53) rear end and BMW X3 side skirt designed car, the Shuanghuan SCEO , also made a copy of the Jeep Cherokee XJ known as
515-496: A growing number of countries and regions all over the world. The largest manufacturers of solar equipment were based in China. Although concentrated solar power capacity grew more than tenfold, it remained a tiny proportion of the total, because the cost of utility-scale solar PV fell by 85% between 2010 and 2020, while CSP costs only fell 68% in the same timeframe. Despite the rising cost of materials, such as polysilicon , during
618-587: A high specific heat capacity, and can deliver heat at temperatures compatible with conventional power systems. This method of energy storage is used, for example, by the Solar Two power station, allowing it to store 1.44 TJ in its 68 m storage tank, enough to provide full output for close to 39 hours, with an efficiency of about 99%. In stand alone PV systems , batteries are traditionally used to store excess electricity. With grid-connected photovoltaic power systems , excess electricity can be sent to
721-413: A leaf spring with a separate shock absorber rear suspension. The Quadra-Link front suspension design locates the axle with four leading control arms to control longitudinal movement and rotation about the lateral axis (drive and braking reaction), two above the axle and two below it. A panhard rod , also referred to as a track bar, is used to locate the axle laterally. Two coil springs are seated on top of
824-691: A limited effect on the users, but their effect on self-consumption of solar power may be limited. The original political purpose of incentive policies for PV was to facilitate an initial small-scale deployment to begin to grow the industry, even where the cost of PV was significantly above grid parity, to allow the industry to achieve the economies of scale necessary to reach grid parity. Since reaching grid parity, some policies are implemented to promote national energy independence, high tech job creation and reduction of CO 2 emissions. Financial incentives for photovoltaics differ across countries, including Australia , China , Germany , India , Japan , and
927-490: A local user or users. Utility-scale solar is sometimes used to describe this type of project. This approach differs from concentrated solar power , the other major large-scale solar generation technology, which uses heat to drive a variety of conventional generator systems. Both approaches have their own advantages and disadvantages, but to date, for a variety of reasons, photovoltaic technology has seen much wider use. As of 2019 , about 97% of utility-scale solar power capacity
1030-504: A measure more directly comparable to other forms of power generation. Most solar parks are developed at a scale of at least 1 MW p . As of 2018, the world's largest operating photovoltaic power stations surpassed 1 gigawatt . At the end of 2019, about 9,000 solar farms were larger than 4 MW AC (utility scale), with a combined capacity of over 220 GW AC . Commercial concentrating solar power (CSP) plants, also called "solar thermal power stations", were first developed in
1133-579: A rate ranging from wholesale to retail rate or above, as can be excess annual credits. A community solar project is a solar power installation that accepts capital from and provides output credit and tax benefits to multiple customers, including individuals, businesses, nonprofits, and other investors. Participants typically invest in or subscribe to a certain kW capacity or kWh generation of remote electrical production. In some countries tariffs (import taxes) are imposed on imported solar panels. The overwhelming majority of electricity produced worldwide

The single rectangular sealed beam headlamps were changed for 1986 to vertically stacked quad low and high beam headlights with front turn signal lights relocated behind the grille. Where the Cherokee tail lights were split in half with a red section above an amber section, the tail lights on Wagoneers had a single red lens. The Wagoneer Limited came with vinyl wood trim on
1339-447: A source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar panels has fallen, grid-connected solar PV systems ' capacity and production has doubled about every three years . Three-quarters of new generation capacity
1442-463: A tenth of their electricity from solar, with China making up more than half of solar growth. Almost half the solar power installed in 2022 was mounted on rooftops . Much more low-carbon power is needed for electrification and to limit climate change . The International Energy Agency said in 2022 that more effort was needed for grid integration and the mitigation of policy, regulation and financing challenges. Nevertheless solar may greatly cut
1545-440: A thin coating of boron. The “Bell Solar Battery” was described as 6% efficient, with a square yard of the panels generating 50 watts. The first satellite with solar panels was launched in 1957 . By the 1970s, solar panels were still too expensive for much other than satellites . In 1974 it was estimated that only six private homes in all of North America were entirely heated or cooled by functional solar power systems. However,
1648-467: Is (or is predicted to become) the cheapest source of energy in all of Central America, Africa, the Middle East, India, South-east Asia, Australia, and several other regions. Different measurements of solar irradiance (direct normal irradiance, global horizontal irradiance) are mapped below: In cases of self-consumption of solar energy, the payback time is calculated based on how much electricity
1751-499: Is 5 millimeters shorter in wheelbase Production under Mercedes-Benz continued in the partnership that was renamed Beijing-Benz DaimlerChrysler Automotive . The most recent model with an updated grille, headlights, and other upgrades was known as the Jeep 2500 and was produced until 2005. It is notable that AMC's original Cherokee design continued to be built and sold after being virtually unchanged for over twenty years. The design of
1854-497: Is a type of solar cell that includes a perovskite-structured compound, most commonly a hybrid organic–inorganic lead or tin halide-based material as the light-harvesting active layer. Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and simple to manufacture. Concentrated solar power (CSP), also called "concentrated solar thermal", uses lenses or mirrors and tracking systems to concentrate sunlight, then uses
1957-568: Is also better, as is ground clearance, as well as approach, departure and breakover angles. These, along with its smaller profile, make the XJ better both off-road and on." Although the XJ models had just been introduced, AMC quickly began the development of its successor. To compete against its much larger rivals, the smallest U.S. automaker created a business process that is now known as " product lifecycle management " (PLM) to speed up its product development process. By 1985, development and engineering
2060-489: Is collected by the Internal Revenue Service (IRS) and normally paid by the manufacturer or importer. The following chart shows the current tax for various levels of MPG that have been in effect since January 1, 1991. The combined fuel economy MPG value (55% city, 45% highway) is used to determine tax liability. The MPG value is also adjusted slightly to account for differences in test procedures made since
2163-455: Is forecast to be solar, surpassing coal as the largest source of installed power capacity. Utility scale is forecast to become the largest source of electricity in all regions except sub-Saharan Africa by 2050. According to a 2021 study, global electricity generation potential of rooftop solar panels is estimated at 27 PWh per year at costs ranging from $ 40 (Asia) to $ 240 per MWh (US, Europe). Its practical realization will however depend on

#17327912258212266-571: Is key for high self-consumption. The match can be improved with batteries or controllable electricity consumption. However, batteries are expensive, and profitability may require the provision of other services from them besides self-consumption increase, for example avoiding power outages . Hot water storage tanks with electric heating with heat pumps or resistance heaters can provide low-cost storage for self-consumption of solar power. Shiftable loads, such as dishwashers, tumble dryers and washing machines, can provide controllable consumption with only
2369-421: Is not purchased from the grid. However, in many cases, the patterns of generation and consumption do not coincide, and some or all of the energy is fed back into the grid. The electricity is sold, and at other times when energy is taken from the grid, electricity is bought. The relative costs and prices obtained affect the economics. In many markets, the price paid for sold PV electricity is significantly lower than
2472-695: Is potentially an important issue, particularly in off-grid applications and for future 100% renewable energy scenarios. Solar is intermittent due to the day/night cycles and variable weather conditions. However solar power can be forecast somewhat by time of day, location, and seasons. The challenge of integrating solar power in any given electric utility varies significantly. In places with hot summers and mild winters, solar tends to be well matched to daytime cooling demands. Concentrated solar power plants may use thermal storage to store solar energy, such as in high-temperature molten salts. These salts are an effective storage medium because they are low-cost, have
2575-489: Is solar, with both millions of rooftop installations and gigawatt-scale photovoltaic power stations continuing to be built. In 2023, solar power generated 5.5% (1,631 TWh) of global electricity and over 1% of primary energy , adding twice as much new electricity as coal. Along with onshore wind power , utility-scale solar is the source with the cheapest levelised cost of electricity for new installations in most countries. As of 2023, 33 countries generated more than
2678-465: Is the conversion of energy from sunlight into electricity , either directly using photovoltaics (PV) or indirectly using concentrated solar power . Solar panels use the photovoltaic effect to convert light into an electric current . Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine . Photovoltaics (PV) were initially solely used as
2781-768: Is then used for power generation or energy storage. Thermal storage efficiently allows overnight electricity generation, thus complementing PV. CSP generates a very small share of solar power and in 2022 the IEA said that CSP should be better paid for its storage. As of 2021 the levelized cost of electricity from CSP is over twice that of PV. However, their very high temperatures may prove useful to help decarbonize industries (perhaps via hydrogen) which need to be hotter than electricity can provide. A hybrid system combines solar with energy storage and/or one or more other forms of generation. Hydro, wind and batteries are commonly combined with solar. The combined generation may enable
2884-435: Is used immediately because traditional generators can adapt to demand and storage is usually more expensive. Both solar power and wind power are sources of variable renewable power , meaning that all available output must be used locally, carried on transmission lines to be used elsewhere, or stored (e.g., in a battery). Since solar energy is not available at night, storing it so as to have continuous electricity availability
2987-881: The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world and brought renewed attention to developing solar technologies. Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the United States (SERI, now NREL ), Japan ( NEDO ), and Germany ( Fraunhofer ISE ). Between 1970 and 1983 installations of photovoltaic systems grew rapidly. In
3090-463: The 2021–2022 global energy crisis , utility scale solar was still the least expensive energy source in many countries due to the rising costs of other energy sources, such as natural gas. In 2022, global solar generation capacity exceeded 1 TW for the first time. However, fossil-fuel subsidies have slowed the growth of solar generation capacity. About half of installed capacity is utility scale. Most new renewable capacity between 2022 and 2027
3193-691: The Cherokee XJ and the S-10 Blazer (in 1984). By the time Ford introduced the Explorer , the SUV had become the common man's luxury vehicle and Ford capitalized on this using extensive cross-marketing, most notably with Northwest clothier Eddie Bauer . Critics of the Gas Guzzler Tax contend that the increased fuel economy of the US passenger car fleet observed since 1978 must be considered in

3296-532: The Chinese market Jeeps was similar to that of the U.S.-market Jeeps , except for a new front grille and headlamps , as well as new tail lamps . The interior also featured a new steering wheel and center console . The BJ2500 , produced by Beijing Jeep was available with the 2.4 L 4G64 engine from Mitsubishi, 2.5 L and 2.7 L engines known as C498QA. Pricing ranged from 115,000 and 127,900 yuan (16,600 to US$ 18,470) for 2.5 L models and
3399-848: The Crude Oil Windfall Profits Tax Act of 1980. The Act also created the Gas Guzzler Tax which applies to the sales of vehicles with official EPA-estimated gas mileage below certain specified levels. In 1980, the tax was $ 200 for a fuel efficiency of 14 to 15 miles per gallon , and was increased to $ 1800 in 1985. In 1980, the tax was $ 550 for fuel efficiencies of 13 mpg and below, and was changed in 1986 to $ 3,850 for ratings below 12.5 mpg. The Gas Guzzler Tax applies only to passenger cars. Trucks, sport utility vehicles (SUV), and minivans are not covered because these vehicle types were not widely available in 1978 and were rarely used for non-commercial purposes. The tax
3502-522: The Jeep Liberty (KJ) , which was branded as a "Cherokee" to ride off the success of the XJ in most foreign markets. The Cherokee (XJ) remains a popular vehicle among off-roading enthusiasts. Its design has been noted as one of the greatest of all time. Popular Mechanics listed the XJ as one of "the 25 greatest boxy cars of all time". When (XJ) Cherokee production ended in June 2001, the portion of

The Chinese market BJ 7250 (rear-wheel drive) and BJ 2021 (four-wheel drive) had a raised roof in the rear, as they were often meant to be chauffeur-driven. The BJ2021 was available with a 2.5 L engine and a four-speed manual gearbox for the 1985 through 2005 model years. For 1993,
3708-467: The United States and even across states within the US. In net metering the price of the electricity produced is the same as the price supplied to the consumer, and the consumer is billed on the difference between production and consumption. Net metering can usually be done with no changes to standard electricity meters , which accurately measure power in both directions and automatically report
3811-486: The electrical grid . Net metering and feed-in tariff programs give these systems a credit for the electricity they produce. This credit offsets electricity provided from the grid when the system cannot meet demand, effectively trading with the grid instead of storing excess electricity. When wind and solar are a small fraction of the grid power, other generation techniques can adjust their output appropriately, but as these forms of variable power grow, additional balance on
3914-399: The silicon solar cell in 1954. These early solar cells cost US$ 286/watt and reached efficiencies of 4.5–6%. In 1957, Mohamed M. Atalla developed the process of silicon surface passivation by thermal oxidation at Bell Labs . The surface passivation process has since been critical to solar cell efficiency . As of 2022 over 90% of the market is crystalline silicon . The array of

Charles Fritts installed the world's first rooftop photovoltaic solar array, using 1%-efficient selenium cells, on a New York City roof in 1884. However, development of solar technologies stagnated in the early 20th century in the face of the increasing availability, economy, and utility of coal and petroleum . Bell Telephone Laboratories’ 1950s research used silicon wafers with

Available in both right- and left-hand-drive models, they were designed to comply with relaxed motor tax regulations in some EU member states governing vehicles intended for primarily commercial use. Both two- and four-door versions are known to have been sold, with
4532-624: The Shuanghuan SHZJ213. The BJ212 platform was used. The SHZJ213 used a 2.4 L BAW 492 engine paired to a five-speed manual gearbox. Production ran from 1994 until 1997. The XJ was manufactured in Toledo, Ohio , USA; Beijing , China ; Ferreyra , Argentina ; Cairo , Egypt ; and in Valencia, Venezuela , with production reaching approximately 3 million between 1983 and 2001. On February 22, 2013, Chrysler released press photos of

Production of the Cherokee Special Service Package continued for the 1997 model year into the 2001 model year. It had the same features as the 1996 Cherokee Special Service Package, but the engine now produced 195 hp (145 kW). After the XJ Cherokee production ended in
4738-454: The U.S. for use by rural mail carriers. After 13 years of production, 1997 saw the Cherokee receive updated exterior and interior styling. Both the two- and four-door bodies remained in production, receiving a steel liftgate (replacing the fiberglass one used previously), restyled taillights, additional plastic molding along the doors, as well as a new front header panel that featured more aerodynamic styling. The spare tire remained mounted to

The productivity of solar power in a region depends on solar irradiance , which varies through the day and year and is influenced by latitude and climate . PV system output power also depends on ambient temperature, wind speed, solar spectrum, the local soiling conditions, and other factors. Onshore wind power tends to be
4944-543: The United States, President Jimmy Carter set a target of producing 20% of U.S. energy from solar by the year 2000, but his successor, Ronald Reagan , removed the funding for research into renewables. Falling oil prices in the early 1980s moderated the growth of photovoltaics from 1984 to 1996. In the mid-1990s development of both, residential and commercial rooftop solar as well as utility-scale photovoltaic power stations began to accelerate again due to supply issues with oil and natural gas, global warming concerns, and
5047-652: The United States, the Jeep Liberty replacement did not offer a Special Service Package. Although Jeep Liberty did not have a special service package, police and government agencies used the Liberty in their fleets for light use. All the transfer cases used on the Cherokee were chain-driven two-speed units with aluminum housings. Command-Trac was standard on XJ models built with 4WD. The Jeep XJ utilizes front and rear beam axle components (live axles) as opposed to an independent suspension . The live axle configuration offers advantages in off-road capability and performance at
5150-400: The XJ Cherokee were offered throughout its lifetime, each having the same track and wheelbase measurements. Two-door models, however, received longer doors and front seats that could fold forward to assist in rear passenger entry and exit. This was in addition to extended-length rear windows that did not open, although an optional rear vent window was available on some models. This version was
5253-565: The XJ Cherokee-based Comanche (MJ) pickup truck was introduced, it was also available in two- and four-wheel drive. The new two-wheel-drive models shared the front suspension (from the track bar, control arms, and ball joints) with four-wheel-drive models. Jeep simply used a single axle tube from hub to hub with no differential between, resulting in an inexpensive front suspension. For 1996, partially to comply with new U.S. OBD-II exhaust and evaporative emissions regulations,

"The new XJ Jeep ... was 1,200 pounds lighter, 31 inches shorter, six inches narrower and four inches lower than the Cherokee SJ it replaced, and yet — thanks to unibody construction — the XJ kept 90 percent of its predecessor’s interior volume." And, not only was fuel economy much improved, but "articulation
5665-523: The ZJ models were introduced in 1993, the XJ models were retained until 2001. The Jeep XJ has remained a popular choice by off-roading enthusiasts due to its potent off-roading capability in stock form. Its popularity has resulted in strong ongoing aftermarket support in the form of a wide variety of products. A variation on the Cherokee from 1983 until 1990 was the Jeep Wagoneer. These were unrelated to

#17327912258216386-537: The context of the increased market share of mid-size and full-size SUVs. Many consumers' stated reasons for SUV purchase (comfort, interior room, and a perception of safety based on the vehicle's size) also apply to the now-obsolete American full-size car as produced from the 1920s through the 70s; critics contend that the dominance of the modern SUV is a direct result of the Gas Guzzler Tax, which could have applied to all consumer vehicles but does not. Solar power Solar power , also known as solar electricity ,
6489-464: The cost of energy. Geography affects solar energy potential because different locations receive different amounts of solar radiation. In particular, with some variations, areas that are closer to the equator generally receive higher amounts of solar radiation. However, solar panels that can follow the position of the Sun can significantly increase the solar energy potential in areas that are farther from
6592-560: The cost of solar power, which is a problem for countries where contracts may not be honoured, such as some African countries. Some countries are considering price caps , whereas others prefer contracts for difference . In many countries, solar power is the lowest cost source of electricity. In Saudi Arabia, a power purchase agreement (PPA) was signed in April 2021 for a new solar power plant in Al-Faisaliah. The project has recorded
6695-581: The desired frequency/phase. Many residential PV systems are connected to the grid when available, especially in developed countries with large markets. In these grid-connected PV systems , use of energy storage is optional. In certain applications such as satellites, lighthouses, or in developing countries, batteries or additional power generators are often added as back-ups. Such stand-alone power systems permit operations at night and at other times of limited sunlight. In "vertical agrivoltaics " system, solar cells are oriented vertically on farmland, to allow
6798-421: The difference, and because it allows homeowners and businesses to generate electricity at a different time from consumption, effectively using the grid as a giant storage battery. With net metering, deficits are billed each month while surpluses are rolled over to the following month. Best practices call for perpetual roll over of kWh credits. Excess credits upon termination of service are either lost or paid for at
6901-586: The dispatching of electricity over up to a 24-hour period. Since peak electricity demand typically occurs at about 5 pm, many CSP power plants use 3 to 5 hours of thermal storage. The typical cost factors for solar power include the costs of the modules, the frame to hold them, wiring, inverters, labour cost, any land that might be required, the grid connection, maintenance and the solar insolation that location will receive. Photovoltaic systems use no fuel, and modules typically last 25 to 40 years. Thus upfront capital and financing costs make up 80% to 90% of
7004-540: The engine management system was upgraded to Chrysler's then-new "JTEC" PCM. This added the side benefits of improving reliability and easing diagnostics. American Motors' compact XJ Cherokee was to be replaced by a new and larger model known as the ZJ (later named the Jeep Grand Cherokee when introduced in 1993) that was under development by AMC. However, the smaller model's continuing popularity caused Chrysler executives to rethink this decision, and while

Solar power plants use one of two technologies: A solar cell , or photovoltaic cell, is a device that converts light into electric current using the photovoltaic effect . The first solar cell was constructed by Charles Fritts in the 1880s. The German industrialist Ernst Werner von Siemens
7210-409: The expense of some on-road comfort and driveability. Mid-1985 and later two-wheel drive models used the same suspension and steering mechanisms with a single tube connecting axle ends, which also meant no transfer case, no front driveshaft, and no front differential. Jeep XJs came in several standard gearing ratios: The Jeep XJ utilizes a coil spring with a separate shock absorber front suspension and
7313-564: The first blow-molded symmetrical instrument panel retainer structure. This instrument panel featured a unique cluster/airbag bracket invented by Peter Gruich that allowed the interchange of the two components for the vehicle to be sold in the right-hand and left-hand drive markets with both driver and passenger airbags. A beeper also replaced the buzzer. A stiffer unibody frame brought improvements to noise, vibration, and harshness (NVH) measurements. Also contributing to NVH improvements were new door seals that reduced wind noise at higher speeds. In
7416-646: The first to be sold in Europe , in the early years, however, only few cars were exported. Notable sales only began in the late eighties or early nineties, depending on the country. In 1988 an import organization was established in Switzerland . In 1989 the Cherokee was launched in France (marketed through Renault), in 1992 in some additional markets, and in 1993 for the United Kingdom . Early versions came with
7519-457: The grid is needed. As prices are rapidly declining, PV systems increasingly use rechargeable batteries to store a surplus to be used later at night. Batteries used for grid-storage can stabilize the electrical grid by leveling out peak loads for a few hours. In the future, less expensive batteries could play an important role on the electrical grid, as they can charge during periods when generation exceeds demand and feed their stored energy into
7622-409: The grid when demand is higher than generation. Jeep Cherokee (XJ) The Jeep Cherokee (XJ) is a sport utility vehicle manufactured and marketed across a single generation by Jeep in the United States from 1983 (model year 1984) through 2001 — and globally through 2014. It was available in two- or four-door, five-passenger, front-engine, rear- or four-wheel drive configurations. Sharing
7725-502: The improving economic position of PV relative to other energy technologies. In the early 2000s, the adoption of feed-in tariffs —a policy mechanism, that gives renewables priority on the grid and defines a fixed price for the generated electricity—led to a high level of investment security and to a soaring number of PV deployments in Europe. For several years, worldwide growth of solar PV was driven by European deployment , but it then shifted to Asia, especially China and Japan , and to
7828-491: The increase in sales and production of fuel efficient vehicles doesn't just encourage people to drive more. The Gas Guzzler Tax led to the successive downsizing of most major American passenger autos, and the combination of the tax and late-'70s/early-'80s economic woes effectively killed the American full-size car as it had been known up to that point. It only took one product cycle before the first modern SUVs were introduced,
7931-448: The interior rear quarter panel on the driver's side in the trunk. A new, unique spare tire carrier was invented by Peter Gruich while working for Jeep Special Programs that utilized the trailer hitch bar and a unique pivot bracket and although it was the only external spare tire carrier to pass the full Jeep durability test, it was not offered for sale. The interior was similarly updated with an all-new design and instrument panel featuring
8034-638: The land to both grow crops and generate renewable energy. Other configurations include floating solar farms , placing solar canopies over parking lots, and installing solar panels on roofs. A thin-film solar cell is a second generation solar cell that is made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal. Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si). A perovskite solar cell (PSC)
8137-549: The main differences from the standard models being metal panels in place of the rear side windows, no rear seats, and a completely flat cargo area. Two- and four-wheel-drive variants were available, powered by the VM Motori 2.5 L diesel engine mated to the Aisin AX-15 manual transmission. Photographs of this model can be found here. American Motors established the first automobile manufacturing joint venture in
8240-589: The manufacturer has to pay for that particular vehicle by using the following equation. p i {\displaystyle {\mathit {p_{i}}}} needs to be looked up on the table above and q i {\displaystyle {\mathit {q_{i}}}} is the numbers of cars that are found to be under the set Gas Guzzler standard, p t = ∑ i p i q i {\displaystyle p_{t}=\sum _{i}{p_{i}q_{i}}\,} Gas guzzler tax creates incentive to meet
8343-404: The middle of the 1999 model year, vehicles with the 4.0 L engine received a revised intake manifold. This was done to help counteract smaller exhaust porting on the latest casting of cylinder heads, which was done to meet more stringent emissions control laws. Both the four- and six-cylinder engines were offered through the 2000 model year, though only the straight-six was available in 2001. For
8446-421: The minimum MPG requirement by manufacturer. Due to elimination of vehicles that are below minimum MPG which is 22.5 MPG, vehicle sales have decreased approximately 0.5 percent. However, sales revenues increase by a greater amount due to the added value in vehicles making greater use of fuel economy technology. Manufacturers benefit from the increase in price of products. However, the fuel sector may lose revenue if
8549-516: The name of the original, full-size Cherokee SJ model, the 1984 XJ Cherokee was Jeep's first all-new design since the 1963 SJ Wagoneer , as well as the first American off-road vehicle built with fully integrated body-and-frame ( unibody ) design, and formed the mechanical basis for the Jeep Comanche (MJ) pickup truck (1986–1992). Jeep marketed XJs as Sportwagons , precursor to the modern sport utility vehicle (SUV), before that term
8652-561: The new replacement for the Liberty , and also announced that the new model would bring back the Cherokee name. The new Cherokee (KL) is built on the compact U.S. wide platform , and features a nine-speed automatic, a choice of a 2.4 L Tigershark I4 with Fiat 's electro-hydraulic MultiAir 2 variable valve timing and variable valve lift or a 3.2 L V6 based on the Pentastar 3.6 L V6, and front and four-wheel drive (the latter
8755-511: The older they get." The XJ Cherokee introduced for the 1984 model year was the first Jeep with a ladder-boxed chassis integrated into a single monocoque unit rather than the traditional separate body-on-frame construction. The design was rigid and sturdy with approximately 3,200 welds in a completed body, "yet wonderfully lightweight, [the] Uniframe permitted outstanding performance even with AMC's new 2.5 L (150 cu in) four-cylinder engine." Both two- and four-door versions of
8858-471: The previous models. However, major changes were underway with a new executive, Wolfgang Bernhard , who was known as a "cost-slasher" nicknamed "whirlwind", who came from Mercedes-Benz to turn Chrysler around. "One of the first moves Bernhard made when he came to Chrysler in 2000 was to help kill the Jeep Cherokee, an aging, somewhat bland SUV." Thus, the (XJ) Cherokee line was replaced in 2001 by
8961-527: The price of bought electricity, which incentivizes self-consumption. Moreover, separate self-consumption incentives have been used in e.g., Germany and Italy. Grid interaction regulation has also included limitations of grid feed-in in some regions in Germany with high amounts of installed PV capacity. By increasing self-consumption, the grid feed-in can be limited without curtailment , which wastes electricity. A good match between generation and consumption
9064-401: The rear of the spring. Two gas-charged shock absorbers are also used, along with a mild anti-sway/anti-roll bar. The suspension used on vehicles with the optional UpCountry package did not include the rear anti-sway/anti-roll bar, but provided one-inch lift over the standard suspension. The XJ was introduced to left-hand drive European markets in 1985, one year after its American debut. However,
9167-422: The resulting heat to generate electricity from conventional steam-driven turbines. A wide range of concentrating technologies exists: among the best known are the parabolic trough , the compact linear Fresnel reflector , the dish Stirling and the solar power tower . Various techniques are used to track the sun and focus light. In all of these systems a working fluid is heated by the concentrated sunlight and
9270-442: The sides and cloth seats with leather bolsters. "Limited" was embossed on the front seat backs and in the center of the rear seat back. The standard equipment list was extensive and included air conditioning, cruise control, power disk brakes, rear window wiper and washer, and adjustable steering wheel. In the early- to mid-1990s, the Jeep Cherokee started becoming popular for government and police use. The Cherokee AHB police package
9373-473: The similarly named full-sized Grand Wagoneer models that had carried the Wagoneer name before this point. The compact XJ Wagoneer was available initially in two trim levels: the "Wagoneer" or "Wagoneer Base" and the "Wagoneer Limited." The "Wagoneer Base" trim was soon discontinued with its last model year being 1987. Both Wagoneers were distinguished from the Cherokee for the 1983 through 1985 model years by
9476-556: The strong U.S. Dollar made the Cherokee expensive and prevented notable sales during the first years. In most countries, import figures only started rising in the late eighties or early nineties. Right-hand drive European markets only began to officially receive Cherokees (in RHD form) in 1993, although a small number of personal imports had been reaching the UK in left-hand drive form for many years before that. Models were offered in both markets until
9579-407: The system to vary power output with demand, or at least smooth the solar power fluctuation. There is much hydro worldwide, and adding solar panels on or around existing hydro reservoirs is particularly useful, because hydro is usually more flexible than wind and cheaper at scale than batteries, and existing power lines can sometimes be used. The early development of solar technologies starting in
9682-504: The weight of the new model. It "is noteworthy as the first nonmilitary 4x4 with unibody construction." The unconventional design enhanced XJ's durability and off-road capability and eventually won over most critics, even those models with early underpowered GM engines. The XJ is described "as the first small crossover SUV in the U.S.," with "plenty of the Jeep toughness (and a straight-six engine) built-in." The design and market positioning of
9785-471: The world's lowest cost for solar PV electricity production of USD 1.04 cents/ kWh. Expenses of high-power band solar modules has greatly decreased over time. Beginning in 1982, the cost per kW was approximately 27,000 American dollars, and in 2006 the cost dropped to approximately 4,000 American dollars per kW. The PV system in 1992 cost approximately 16,000 American dollars per kW and it dropped to approximately 6,000 American dollars per kW in 2008. In 2021 in
9888-624: Was 128,000 yuan for the 2.7 L version (US$ 18,480). while 4.0 L and 4.7 L engines were known as C698QA1 and C8V93Q respectively, and both power the Jeep Grand Cherokee (WJ) . After 2009 Beijing Auto Works continued the production of the Chinese-market XJ Cherokee as the BAW Qishi 骑士 (Knight in Chinese). The Qishi uses a 2.0 L I4 and 2.2 L I4 known as the 4G20 and 4G22, both old Nissan units, and
9991-454: Was PV. In some countries, the nameplate capacity of photovoltaic power stations is rated in megawatt-peak (MW p ), which refers to the solar array's theoretical maximum DC power output. In other countries, the manufacturer states the surface and the efficiency. However, Canada, Japan, Spain, and the United States often specify using the converted lower nominal power output in MW AC ,
10094-616: Was also made in right-hand drive format, initially for the United States Postal Service . As a spin-off, it allowed Jeep in later years to enter right-hand drive markets — the Cherokee went on sale in both the United Kingdom and Ireland in 1993. It was also sold in Japan , but due to the country's strict "Shaken" motor-vehicle inspection laws, many used Japanese-market Cherokees have found their way back to
10197-506: Was among those who recognized the importance of this discovery. In 1931, the German engineer Bruno Lange developed a photo cell using silver selenide in place of copper oxide , although the prototype selenium cells converted less than 1% of incident light into electricity. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created
10300-645: Was based on computer-aided design (CAD) software systems while new systems stored all drawings and documents in a central database. The pioneering PLM was so effective that after Chrysler purchased AMC in 1987, it expanded the system throughout its enterprise. British TV presenter and motoring expert Quentin Willson described the XJ Jeep as "a real 4x4 icon" and one of the "few truly great cars... which, despite being left behind by newer models, still offer fresh and urgent possibilities. Cars which become more relevant
10403-410: Was developing a new two-door S-10-based Blazer, AMC decided to develop an entirely new four-door model in addition to a two-door version. American Motors' vice president of engineering, Roy Lunn , designed what is known as the "Quadra-Link" suspension, that limited rollovers. Renault's François Castaing developed the drivetrain using a much smaller engine than normally found in 4WD vehicles and reduced
10506-501: Was introduced during the 1992 model year. Starting in 1996, Jeep released a special version of the XJ Cherokee SE for police and fleet use. It featured no interior rear door handles and a revised 190 hp (142 kW) high output version of the 4.0 L "Power-Tech" inline six-cylinder engine. The new HO engine replaced the previous 177 hp (132 kW) version of the 4.0 L engine in all installations. The Cherokee
10609-575: Was used. The XJ is credited for spawning competitors, as other automakers noticed the design cannibalizing sales from regular cars, supplanting the role of the station wagon and transforming the vehicle type "from truck to limousine in the eyes of countless suburban owners," though GM had also launched road-biased, RWD and 4WD compact SUVs, the Chevrolet S-10 Blazer and GMC S-15 Jimmy, one year earlier, initially available in two-door form only. The 2007 book Jeep Off-Road called
