The army force-marched 1,700 non-hostile Dakota men, women, children, and elders 150 miles (240 km) to a concentration camp at Fort Snelling . Minneapolitans reportedly threatened more than once to attack the camp. In 1863, the US "abrogated and annulled" all treaties with the Dakota. With Governor Alexander Ramsey calling for their extermination, most Dakota were exiled from Minnesota. While
10650-551: The Mississippi River. Location near the fort and the falls' power—with its potential for industrial activity—fostered the city's early growth. For a time in the 19th century, Minneapolis was the lumber and flour milling capital of the world, and as home to the Federal Reserve Bank of Minneapolis , it has preserved its financial clout into the 21st century. A Minneapolis Depression-era labor strike brought about federal worker protections. Work in Minneapolis contributed to
10800-677: The Power for the Plains Initiative, Xcel Energy built hundreds of miles of transmission lines and substations totaling $ 3 billion in investment. The lines supply Kiowa NM, Lubbock TX, and connect other towns in the Texas panhandle. The transmission system is operated on a non-discriminatory basis under the open access requirements of the Federal Government . This means that all wholesale buyers and sellers of electricity can use
10950-434: The Twin Cities metropolitan area tied with Boston as having the eighth-highest concentration of major corporate headquarters in the US. Five Fortune 500 corporations were headquartered within the city limits of Minneapolis: Target Corporation , U.S. Bancorp , Xcel Energy , Ameriprise Financial , and Thrivent . The metro area's gross domestic product was $ 323.9 billion in 2022 ($ 337 billion in 2023). During
11100-562: The US and co-cathedral of the Roman Catholic Archdiocese of Saint Paul and Minneapolis , was named by Pope Pius XI in 1926. The Billy Graham Evangelistic Association was headquartered in Minneapolis from the 1950s until 2001. Christ Church Lutheran in the Longfellow neighborhood was the final work in the career of Eliel Saarinen , and it has an education building designed by his son Eero . Aligning with
11250-419: The US average of 11.1 percent. As of 2022, 90.8 percent of residents age 25 years or older had earned a high school degree compared to 89.1 percent nationally, and 53.5 percent had a bachelor's degree or higher compared to the 34.3 percent US national average. US veterans made up 2.8 percent of the population compared to the national average of 5 percent in 2023. In Minneapolis in 2020, Blacks owned homes at
11400-1034: The Washington County Light & Power Co. in 1909. When H. M. Byllesby began building his utility holding company across the Northwestern region of the US, he renamed it the Consumers Power Co. in 1910 and which was renamed the Northern States Power Co. in 1916. While the bulk of NSP's territory grew across central and southern Minnesota (starting from the Twin Cities), it acquired territory in North Dakota (centering on Fargo, Grand Forks, and Minot) and extended southwest into South Dakota (centering on Sioux Falls). NSP's system also extended east into Wisconsin, but because of utility ownership laws in that state, it
11550-565: The beginning of the American Civil War, annuity payments owed in June 1862 to the Dakota by treaty were late, causing acute hunger among the Dakota. Facing starvation a faction of the Dakota declared war in August and killed settlers. Serving without any prior military experience, US commander Henry Sibley commanded raw recruits, volunteer mounted troops from Minneapolis and Saint Paul with no military experience. The war went on for six weeks in
11700-557: The chief viable alternative of fossil fuel. Proponents also believe that nuclear power is the only viable course to achieve energy independence for most Western countries. They emphasize that the risks of storing waste are small and can be further reduced by using the latest technology in newer reactors, and the operational safety record in the Western world is excellent when compared to the other major kinds of power plants. Opponents say that nuclear power poses many threats to people and
11850-450: The city became more and more racially divided. Though such language was prohibited by state law in 1953 and by the federal Fair Housing Act of 1968 , restrictive covenants against minorities remained in many Minneapolis deeds as of the 2020s. In 2021, the city gave residents a means to discharge them. Minneapolis has a history of structural racism and has racial disparities in nearly every aspect of society. As White settlers displaced
12000-539: The city in the 21st century. Governed by a mayor-council system, Minneapolis has a political landscape dominated by the Minnesota Democratic–Farmer–Labor Party (DFL), with Jacob Frey serving as mayor since 2018. Two Indigenous nations inhabited the area now called Minneapolis. Archaeologists have evidence that since 1000 A.D., they were the Dakota (one half of the Sioux nation), and, after
12150-410: The city into crime, and tried to leave town in 1902. The Ku Klux Klan was a force in the city from 1921 until 1923. The gangster Kid Cann engaged in bribery and intimidation between the 1920s and the 1940s. After Minnesota passed a eugenics law in 1925, the proprietors of Eitel Hospital sterilized people at Faribault State Hospital . During the summer of 1934 and the financial downturn of
12300-615: The city of Roswell, New Mexico and its 2,000 residents. The financial strain of creating this new enterprise soon overwhelmed him and he sold the franchise to W.H. Gillenwater, who named his utility the Roswell Electric Light Co. He later sold the company to an investment firm in Cleveland, Ohio, which already owned the Roswell Gas Co. Northern States Power Company's timeline begins with the organization of
12450-609: The city set up the Neighborhood Revitalization Program (NRP), in which every one of the city's eighty-some neighborhoods participated. Funded for 20 years through 2011, with $ 400 million tax increment financing ($ 542 million in 2023), the program caught the eye of UN-Habitat , who considered it an example of best practices . Residents had a direct connection to government in NRP, whereby they proposed ideas appropriate for their area, and NRP reviewed
12600-493: The city's defining physical characteristic. Long periods of glaciation and interglacial melt carved several riverbeds through what is now Minneapolis. During the last glacial period , around 10,000 years ago, ice buried in these ancient river channels melted, resulting in basins that filled with water to become the lakes of Minneapolis . Meltwater from Lake Agassiz fed the Glacial River Warren , which created
12750-497: The city's history, millers were required to pay for wheat with cash during the growing season and then to store the wheat until it was needed for flour. The Minneapolis Grain Exchange was founded in 1881; located near the riverfront, it is the only exchange as of 2023 for hard red spring wheat futures . Along with cash requirements for the milling industry, the large amounts of capital that lumbering had accumulated stimulated
12900-421: The city's mid-20th century population decline. But because of a few radicalized persons, the city's large Somali population was targeted with discrimination after 9/11 , when its hawalas or banks were closed. In 2020, 17-year-old Darnella Frazier recorded the murder of George Floyd ; Frazier's video contradicted the police department's initial statement. Floyd, a Black man, suffocated when Derek Chauvin ,
13050-470: The collection of more than 90,000 artworks spans six continents and about 5,000 years. Frank Gehry designed Weisman Art Museum , which opened in 1993, for the University of Minnesota . A 2011 addition by Gehry doubled the size of the galleries. The Museum of Russian Art opened in a restored church in 2005, and it hosts a collection of 20th-century Russian art and special events. The Northeast Minneapolis Arts District hosts 400 independent artists and
13200-576: The combined risk of the temporary design of the storage facility, unpredictable flooding and single evacuation road in the event nuclear waste is released from containment. Xcel Energy faces more than 200 lawsuits filed by victims of the Marshall Fire , which started on December 30, 2021, Boulder County, and spread across Superior and Louisville counties in Colorado. Two people died and more than 1,000 homes and commercial properties were destroyed, resulting in more than $ 2 billion in property damage. It
13350-669: The company merged with SPS to form New Century Energies ( NCE ) in 1995. Northern States Power and Wisconsin Energy Corporation had planned to merge into a new outfit that was to be called Primergy - but in 1997, the merger fell through because of the time it was taking to gain the required approvals from state and federal agencies. After the failed Primergy merger, NSP (both the Minnesota and Wisconsin companies) merged with New Century Energies to form Xcel Energy. In 2005, Xcel sold Cheyenne Light, Fuel and Power to Black Hills Corporation . Cheyenne Light, Fuel and Power had been
13500-676: The computing industry, and the city is the birthplace of General Mills , the Pillsbury brand, Target Corporation , and Thermo King mobile refrigeration. The city's major arts institutions include the Minneapolis Institute of Art , the Walker Art Center , and the Guthrie Theater . Four professional sports teams play downtown. Prince is survived by his favorite venue, the First Avenue nightclub . Minneapolis
13650-493: The costs of fuel extraction, processing, use and spent fuel storage internalized costs. Therefore, comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear stations. Cost estimates take into account station decommissioning and nuclear waste storage or recycling costs in the United States due to the Price Anderson Act . With
13800-424: The destruction of a turbine in operation from flying towards the reactor. In the case of a pressurized water reactor, the steam turbine is separated from the nuclear system. To detect a leak in the steam generator and thus the passage of radioactive water at an early stage, an activity meter is mounted to track the outlet steam of the steam generator. In contrast, boiling water reactors pass radioactive water through
13950-458: The dismantling of other power stations is the presence of radioactive material that requires special precautions to remove and safely relocate to a waste repository. Decommissioning involves many administrative and technical actions. It includes all clean-up of radioactivity and progressive demolition of the station. Once a facility is decommissioned, there should no longer be any danger of a radioactive accident or to any persons visiting it. After
14100-562: The end of World War I in 1918 until 1950, antisemitism was commonplace in Minneapolis— Carey McWilliams called the city the antisemitic capital of the US. Starting in 1936, a fascist hate group known as the Silver Shirts held meetings in the city. In the 1940s, mayor Hubert Humphrey worked to rescue the city's reputation and helped the city establish the country's first municipal fair employment practices and
14250-534: The energy-intensive stages of the nuclear fuel chain are considered, from uranium mining to nuclear decommissioning , nuclear power is not a low-carbon electricity source despite the possibility of refinement and long-term storage being powered by a nuclear facility. Those countries that do not contain uranium mines cannot achieve energy independence through existing nuclear power technologies. Actual construction costs often exceed estimates, and spent fuel management costs are difficult to define. On 1 August 2020,
14400-402: The environment and raising the possibility of nuclear proliferation." Nuclear power plants do not produce greenhouse gases during operation. Older nuclear power plants, like ones using second-generation reactors , produce approximately the same amount of carbon dioxide during the whole life cycle of nuclear power plants for an average of about 11g/kWh, as much power generated by wind , which
14550-775: The environment, and that costs do not justify benefits. Threats include health risks and environmental damage from uranium mining , processing and transport, the risk of nuclear weapons proliferation or sabotage, and the problem of radioactive nuclear waste . Another environmental issue is discharge of hot water into the sea. The hot water modifies the environmental conditions for marine flora and fauna. They also contend that reactors themselves are enormously complex machines where many things can and do go wrong, and there have been many serious nuclear accidents . Critics do not believe that these risks can be reduced through new technology , despite rapid advancements in containment procedures and storage methods. Opponents argue that when all
14700-411: The environment. In addition, many reactors are equipped with a dome of concrete to protect the reactor against both internal casualties and external impacts. The purpose of the steam turbine is to convert the heat contained in steam into mechanical energy. The engine house with the steam turbine is usually structurally separated from the main reactor building. It is aligned so as to prevent debris from
14850-525: The expected growth of nuclear power from 2005 to 2055, at least four serious nuclear accidents would be expected in that period. The MIT study does not take into account improvements in safety since 1970. Nuclear power works under an insurance framework that limits or structures accident liabilities in accordance with the Paris Convention on Third Party Liability in the Field of Nuclear Energy ,
15000-689: The falls. Lumbering's decline began around the turn of the century, and sawmills in the city including the Weyerhauser mill closed by 1919. After depleting Minnesota's white pine, some lumbermen moved on to Douglas fir in the Pacific Northwest . In 1877, Cadwallader C. Washburn co-founded Washburn-Crosby, the company that became General Mills . Washburn and partner John Crosby sent Austrian civil engineer William de la Barre to Hungary where he acquired innovations through industrial espionage . De la Barre calculated and managed
15150-591: The first Filipinos came to attend the University of Minnesota . Vietnamese , Hmong (some from Thailand ), Lao , and Cambodians settled mainly in Saint Paul around 1975, but some built organizations in Minneapolis. In 1992, 160 Tibetan immigrants came to Minnesota, and many settled in the city's Whittier neighborhood. Burmese immigrants arrived in the early 2000s, with some moving to Greater Minnesota . The population of people from India in Minneapolis increased by 1,000 between 2000 and 2010, making it
15300-535: The first major US utility to set such a goal. Xcel Energy was built on three companies: Minneapolis-based Northern States Power Company (NSP), Denver-based Public Service Company of Colorado (PSCo), and Amarillo-based Southwestern Public Service (SPS). Southwestern Public Service Co. (SPS) dates its origins to 1904 and the Pecos Valley in New Mexico when Maynard Gunsell received an electricity franchise for
15450-779: The grid. However the cost can be significant. Colorado regulators did not approve Xcel's plan to build additional transmission in Baca County which is a large potential wind energy generator. Instead, they sought proposals that involve constructing renewable energy sources connected to the existing grid. In Minnesota, the budget for a new 465 mile transmission line doubled to $ 1.14 billion and Xcel cited inflationary pressures. Opponents of Colorado's Power Pathway Program highlighted that cost overruns in transmission construction will be pushed to consumers. The Federal Energy Information Administration stated in 2023 that transmission lines typically cost $ 1.17 million to $ 8.62 million per mile. Under
15600-484: The high voltage power lines for long distance transport of electric energy. Xcel Energy owns and operates 110,000 miles of such lines. Xcel has proposed significant plans for updating its transmission system with a budget of $ 7.4 billion from 2022-2027. The Colorado Power Pathway, approved by regulators in 2022, gives Xcel $ 1.7 billion to expand transmission infrastructure in eastern Colorado. One proposal in Colorado involved nearly $ 3 billion in new investment. Construction
15750-406: The hot coolant is used as a heat source for a boiler, and the pressurized steam from that drives one or more steam turbine driven electrical generators . In the event of an emergency, safety valves can be used to prevent pipes from bursting or the reactor from exploding. The valves are designed so that they can derive all of the supplied flow rates with little increase in pressure. In the case of
15900-467: The housing disparities created the educational disparities that we still live with today." Professor Samuel Myers Jr. says of redlining , "Policing policies evolved that substituted explicit racial profiling with scientific management of racially disparate arrests. ... racially discriminatory policies became institutionalized and 'baked in' to the fabric of Minnesota life." Government efforts to address these disparities included zoning changes passed in
16050-517: The initial investments are financed. Because of this high construction cost and lower operations, maintenance, and fuel costs, nuclear plants are usually used for base load generation, because this maximizes the hours over which the fixed cost of construction can be amortized. Nuclear power plants have a carbon footprint comparable to that of renewable energy such as solar farms and wind farms , and much lower than fossil fuels such as natural gas and coal . Nuclear power plants are among
16200-481: The intersection where Floyd died, now known as George Floyd Square , with the slogan "No justice, no street". Minneapolis gathered ideas for the square and through community engagement promised final proposals for the end of 2024, that could be implemented by 2026 or thereafter. Protesters continued to ask for twenty-four reforms—many now met; a sticking point was ending qualified immunity for police. The history and economic growth of Minneapolis are linked to water,
16350-569: The largest concentration of Indians living in the state. The population of Minneapolis grew until 1950 when the census peaked at 521,718—the only time it has exceeded a half million. The population then declined for decades; after World War II, people moved to the suburbs and generally out of the Midwest. By 1930, Minneapolis had one of the nation's highest literacy rates among Black residents. However, discrimination prevented them from obtaining higher-paying jobs. In 1935, Cecil Newman and
16500-598: The largest wildfire in Texas History, burning more than 1 million acres and resulting in at least two deaths and extensive property damage and livestock losses. An investigation by the Texas A&;M Forest Service found that power lines ignited the fire. Minneapolis, Minnesota Minneapolis is a city in and the county seat of Hennepin County, Minnesota , United States. With a population of 429,954, it
16650-517: The lives of people in the 21st century. The city wrote in a decennial plan that racially discriminatory federal housing policies starting in the 1930s "prevented access to mortgages in areas with Jews, African-Americans and other minorities" and "left a lasting effect on the physical characteristics of the city and the financial well-being of its residents". Discussing a Federal Reserve Bank of Minneapolis report on how systemic racism compromises education in Minnesota, Professor Keith Mayes says, "So
16800-756: The local banking industry and made Minneapolis a major financial center. The Federal Reserve Bank of Minneapolis serves Minnesota, Montana , North and South Dakota , and parts of Wisconsin and Michigan ; it has the smallest population of the twelve districts in the Federal Reserve System , and it has one branch in Helena, Montana . Minneapolis area employment is primarily in trade, transportation, utilities, education, health services, and professional and business services. Smaller numbers of residents are employed in government, manufacturing, leisure and hospitality, and financial activities. In 2022,
16950-499: The median income for a Black family was $ 34,377 less than a White family's median income, an improvement of $ 7,000 since 2019. Before 1910, when a developer wrote the first restrictive covenant based on race and ethnicity into a Minneapolis deed, the city was relatively unsegregated with a Black population of less than one percent. Realtors adopted the practice, thousands of times preventing non-Whites from owning or leasing properties; this practice continued for four decades until
17100-607: The need to spend more on redundant back up safety equipment. According to the World Nuclear Association , as of March 2020: The Russian state nuclear company Rosatom is the largest player in international nuclear power market, building nuclear plants around the world. Whereas Russian oil and gas were subject to international sanctions after the Russian full-scale invasion of Ukraine in February 2022, Rosatom
17250-681: The nickname "Mill City". Due to the occupational hazards of milling, six companies manufactured artificial limbs. Disasters struck in the late 19th century: the Eastman tunnel under the river leaked in 1869; twice, fire destroyed the entire row of sawmills on the east bank; an explosion of flour dust at the Washburn A mill killed eighteen people and demolished about half the city's milling capacity; and in 1893, fire spread from Nicollet Island to Boom Island to northeast Minneapolis, destroyed twenty blocks, and killed two people. The lumber industry
17400-483: The now decommissioned German Biblis Nuclear Power Plant was designed to modulate its output 15% per minute between 40% and 100% of its nominal power. Russia has led in the practical development of floating nuclear power stations , which can be transported to the desired location and occasionally relocated or moved for easier decommissioning. In 2022, the United States Department of Energy funded
17550-676: The nuclear waste containment site. The island is very vulnerable to seasonal flooding because it is on the bank of the Mississippi River . While in 1991, the Minnesota Public Utilities Commission capped the storage of nuclear waste on the island to 17 casks, the legislature has since permitted this number to increase. Environmentalists and members of the Prairie Island Indian Community have been working since 1994 to have this nuclear waste transported away from their reservation due to
17700-704: The plan, and then securing its survival. Ultimately in 2024, the state legislature passed a bill approving the city's 2040 plan. Minneapolis experiences a hot-summer humid continental climate ( Dfa in the Köppen climate classification ) that is typical of southern parts of the Upper Midwest ; it is situated in USDA plant hardiness zone 5a. The Minneapolis area experiences a full range of precipitation and related weather events, including snow, sleet, ice, rain, thunderstorms, and fog. The highest recorded temperature
17850-588: The plans and provided implementation funds. The city's Neighborhood and Community Relations department took NRP's place in 2011 and is funded only by city revenue. In 2019, the city released the Neighborhoods 2020 program, which reworked neighborhood funding with an equity-focused lens. This reduced guaranteed funding, and several neighborhood organizations have since struggled with operations or merged with other neighborhoods due to decreased revenue. Base funding for every neighborhood organization increased in
18000-511: The population was born abroad , with 53.2 percent of them being naturalized US citizens . Most immigrants arrived from Africa (40.6 percent), Latin America (25.2 percent), and Asia (24.6 percent), with 34.6 percent of all foreign-born residents having arrived in 2010 or earlier. Comparable to the US average of $ 70,784 in 2021, the ACS reported that the 2021 median household income in Minneapolis
18150-418: The power at the falls and encouraged steam for auxiliary power. Charles Alfred Pillsbury and the C. A. Pillsbury Company across the river hired Washburn-Crosby employees and began using the new methods. The hard red spring wheat grown in Minnesota became valuable, and Minnesota "patent" flour was recognized at the time as the best bread flour in the world. In 1900, fourteen percent of America's grain
18300-474: The prospect that all spent nuclear fuel could potentially be recycled by using future reactors, generation IV reactors are being designed to completely close the nuclear fuel cycle . However, up to now, there has not been any actual bulk recycling of waste from a NPP, and on-site temporary storage is still being used at almost all plant sites due to construction problems for deep geological repositories . Only Finland has stable repository plans, therefore from
18450-427: The reactor by the condensate and feedwater pumps. In the main condenser, the wet vapor turbine exhaust come into contact with thousands of tubes that have much colder water flowing through them on the other side. The cooling water typically come from a natural body of water such as a river or lake. Palo Verde Nuclear Generating Station , located in the desert about 97 kilometres (60 mi) west of Phoenix, Arizona,
18600-540: The risks of future uncertainties. To date all operating nuclear power stations were developed by state-owned or regulated utilities where many of the risks associated with construction costs, operating performance, fuel price, and other factors were borne by consumers rather than suppliers. Many countries have now liberalized the electricity market where these risks and the risk of cheaper competitors emerging before capital costs are recovered, are borne by station suppliers and operators rather than consumers, which leads to
18750-510: The river's west bank included woolen mills, iron works, a railroad machine shop, and mills for cotton, paper, sashes, and wood-planing. Minneapolis supplied the materials for farmsteads and settlement of rapidly expanding cities on the prairies that lacked wood. White pine milled in Minneapolis built Miles City, Montana ; Bismarck, North Dakota ; Sioux Falls, South Dakota ; Omaha, Nebraska ; and Wichita, Kansas . Growing use of steam power freed lumbermen and their sawmills from dependence on
18900-660: The safest modes of electricity generation, comparable to solar and wind power plants. The first time that heat from a nuclear reactor was used to generate electricity was on December 21, 1951, at the Experimental Breeder Reactor I , powering four light bulbs. On June 27, 1954, the world's first nuclear power station to generate electricity for a power grid , the Obninsk Nuclear Power Plant , commenced operations in Obninsk , in
19050-407: The same element. Different isotopes also have different half-lives . U-238 has a longer half-life than U-235, so it takes longer to decay over time. This also means that U-238 is less radioactive than U-235. Since nuclear fission creates radioactivity, the reactor core is surrounded by a protective shield. This containment absorbs radiation and prevents radioactive material from being released into
19200-506: The second half of the 20th century. Between 1958 and 1963, Minneapolis demolished " skid row ". Gone were 35 acres (10 ha) with more than 200 buildings, or roughly 40 percent of downtown, including the Gateway District and its significant architecture such as the Metropolitan Building . Opened in 1967, I-35W displaced Black and Mexican neighborhoods in south Minneapolis. In 1968, relocated Native Americans founded
19350-529: The solar rebate program before reaching a settlement a month later with representatives of solar power companies to restore the solar incentive program until it is fully reviewed by the Public Utilities Commission. On August 1, 2002, Xcel Energy Inc. was sued because of engaging in "round-trip" energy trades that provided no economic benefit for the company, and because the company lacked the necessary internal controls to adequately monitor
19500-558: The spent fuel from these nuclear plants on site in independent spent fuel storage installations. (ISFSIs). Biomass electricity comes from organic fuel sources. Xcel Energy has contracts for about 110 megawatts of electricity from biomass generators. Two in northern Minnesota are fueled by forest harvest residue, such as treetops and limbs. A third facility, brought on line in 2007 in western Minnesota, generates power using turkey litter. Xcel Energy's Bay Front plant in Ashland, Wisconsin ,
19650-693: The steam generator and the nuclear reactor is controlled using the feedwater system. The feedwater pump has the task of taking the water from the condensate system, increasing the pressure and forcing it into either the steam generators—in the case of a pressurized water reactor — or directly into the reactor, for boiling water reactors . Continuous power supply to the plant is critical to ensure safe operation. Most nuclear stations require at least two distinct sources of offsite power for redundancy. These are usually provided by multiple transformers that are sufficiently separated and can receive power from multiple transmission lines. In addition, in some nuclear stations,
19800-487: The steam turbine, so the turbine is kept as part of the radiologically controlled area of the nuclear power station. The electric generator converts mechanical power supplied by the turbine into electrical power. Low-pole AC synchronous generators of high rated power are used. A cooling system removes heat from the reactor core and transports it to another area of the station, where the thermal energy can be harnessed to produce electricity or to do other useful work. Typically
19950-690: The supply of housing so more neighborhoods would be affordable and to decrease the effects single-family zoning had caused on racial disparities and segregation. The Brookings Institution called it "a relatively rare example of success for the YIMBY agenda". From 2022 until 2024, the Minnesota Supreme Court , the US District Court , and the Minnesota Court of Appeals arrived at competing opinions, first shutting down
20100-589: The trading of its power. Xcel paid $ 80,000,000 in a settlement. The Cabin Creek Fire occurred on October 2, 2007, at Xcel Energy's Hydropower Generation plant in Georgetown, Colorado . On June 1, 2011, Federal prosecutors opened their charges that Xcel Energy was criminally liable for the deaths of the five RPI workers. The jury found Xcel Energy not guilty. On December 19, 2011, RPI Coating plead guilty to workplace safety violations and paid $ 1.55 million in
20250-610: The transmission system under the same terms and conditions used to serve Xcel Energy's own retail customers. In 2017, Xcel Energy partnered with the Financial Services Information Sharing and Analysis Center to create a new "threat information sharing community" intended to share cyber and physical security intelligence with the energy sector. The new community is called the Energy Analytic Security Exchange (EASE). It
20400-477: The turbine generator can power the station's loads while the station is online, without requiring external power. This is achieved via station service transformers which tap power from the generator output before they reach the step-up transformer. Nuclear power plants generate approximately 10% of global electricity, sourced from around 440 reactors worldwide. They are recognized as a significant provider of low-carbon electricity , accounting for about one-quarter of
20550-663: The turn of the 21st century, Latinos were the state's largest and fastest-growing immigrant group. Immigrants from Sweden , Norway , and Denmark found common ground with the Republican and Protestant belief systems of the New England migrants who preceded them. Irish , Scots , and English immigrants arrived after the Civil War; Germans and Jews from Central and Eastern Europe , as well as Russia , followed. Minneapolis welcomed Italians and Greeks in
20700-459: The world's supply in this category. As of 2020, nuclear power stood as the second-largest source of low-carbon energy, making up 26% of the total. Nuclear power facilities are active in 32 countries or regions, and their influence extends beyond these nations through regional transmission grids, especially in Europe. In 2022, nuclear power plants generated 2545 terawatt-hours (TWh) of electricity,
20850-436: Was $ 69,397 ($ 78,030 in 2023), It was $ 97,670 for families, $ 123,693 for married couples, and $ 54,083 for non-family households. In 2023, the median Minneapolis rent was $ 1,529, compared to the national median of $ 1,723. Over 92 percent of housing units in Minneapolis were occupied. Housing units in the city built in 1939 or earlier comprised 43.7 percent. Almost 17 percent of residents lived in poverty in 2023, compared to
