Question: In terms of wind energy production, where does the state where wind power is used the most in the U.S. rank?

full_context: Document 1: Altamont Pass wind farm: The Altamont Pass wind farm is located in the Altamont Pass of the Diablo Range in Northern California. It is one of the earliest wind farms in the United States. The first wind turbines were placed on the Altamont in the early 1980s by Fayette Manufacturing Corporation on land owned by cattle rancher Joe Jess. The wind farm is composed of 4930 relatively small wind turbines of various types, making it at one time the largest wind farm in the world in terms of capacity. Altamont Pass is still one of the largest concentration of wind turbines in the world, with a capacity of 576 megawatts (MW), producing about 125 MW on average and 1.1 terawatt-hours (TWh) yearly. They were installed after the 1970s energy crisis in response to favorable tax policies for investors.
Document 2: Intrepid Wind Farm: The Intrepid Wind Farm consists of 107 wind turbines, located in Sac and Buena Vista counties in north-west Iowa, has a generating capacity of 160.5 megawatts of electricity. The wind power project is MidAmerican Energy Company’s first owned and operated wind generation facility and became operational on December 31, 2004.
Document 3: Republic of Ireland: The Atlantic Ocean and the warming influence of the Gulf Stream affect weather patterns in Ireland. Temperatures differ regionally, with central and eastern areas tending to be more extreme. However, due to a temperate oceanic climate, temperatures are seldom lower than −5 °C (23 °F) in winter or higher than 26 °C (79 °F) in summer. The highest temperature recorded in Ireland was 33.3 °C (91.9 °F) on 26 June 1887 at Kilkenny Castle in Kilkenny, while the lowest temperature recorded was −19.1 °C (−2.4 °F) at Markree Castle in Sligo. Rainfall is more prevalent during winter months and less so during the early months of summer. Southwestern areas experience the most rainfall as a result of south westerly winds, while Dublin receives the least. Sunshine duration is highest in the southeast of the country. The far north and west are two of the windiest regions in Europe, with great potential for wind energy generation.
Document 4: Blue Canyon Wind Farm: Blue Canyon Wind Farm is the largest wind farm in Oklahoma, United States. The project, located in the Slick Hills north of Lawton, consists of four phases with a total output of 423.45 MW.
Document 5: Renewable energy commercialization: As of 2014, the wind industry in the USA is able to produce more power at lower cost by using taller wind turbines with longer blades, capturing the faster winds at higher elevations. This has opened up new opportunities and in Indiana, Michigan, and Ohio, the price of power from wind turbines built 300 feet to 400 feet above the ground can now compete with conventional fossil fuels like coal. Prices have fallen to about 4 cents per kilowatt-hour in some cases and utilities have been increasing the amount of wind energy in their portfolio, saying it is their cheapest option.
Document 6: Climate of Hawaii: The Pacific High, and with it the trade - wind zone, moves north and south with changing angle of the sun, so that it reaches its northernmost position in the summer. This brings trade winds during the period of May through September, when they are prevalent 80 to 95 percent of the time. From October through April, the heart of the trade winds moves south of Hawaii; however, the winds still blow much of the time. They provide a system of natural year - long ventilation throughout the islands and bring mild temperatures characteristic of air that has moved great distances across tropical waters.
Document 7: Climate of North Dakota: Autumn weather in North Dakota is largely the reverse of spring weather. The jet stream, which tends to weaken in summer, begins to re-strengthen, leading to a quicker changing of weather patterns and an increased variability of temperatures. By late October and November these storm systems become strong enough to form major winter storms. Fall and spring are the windiest times of the year in North Dakota.
Document 8: Top of the World Windpower Project: The Top of the World Windpower Project is a 200 megawatt wind farm located near Casper, Wyoming, USA. The project, operated by Duke Energy, was constructed on approximately of land held under long-term lease in Converse County. The Top of the World Windpower Project began operation in 2010.
Document 9: Wrigley Field: In April and May the wind often comes off Lake Michigan (less than a mile to the east), which means a northeast wind ``blowing in ''to knock down potential home runs and turn them into outs. In the summer, however, or on any warm and breezy day, the wind often comes from the south and the southwest, which means the wind is`` blowing out'' and has the potential to turn normally harmless fly balls into home runs. A third variety is the cross-wind, which typically runs from the left field corner to the right field corner and causes all sorts of havoc. Depending on the direction of the wind, Wrigley can either be one of the friendliest parks in the major leagues for pitchers or among the worst. This makes Wrigley one of the most unpredictable parks in the Major Leagues.
Document 10: Tatanka Wind Farm: The 180 MW Tatanka Wind Farm, is located in Dickey County and McIntosh County, North Dakota, and McPherson County, South Dakota. It is the largest wind farm in North and South Dakota and generates enough renewable energy to power more than 60,000 U.S. homes.
Document 11: Wind power in Indiana: Wind power in Indiana was limited to a few small water - pumping windmills on farms until 2008 with construction of Indiana's first utility - scale wind power facility, Goodland (phase I) with a nameplate capacity of 130 MW. As of September 2017, Indiana had a total of 1897 MW of wind power capacity installed, ranking it 12th among U.S. states.
Document 12: Renewable energy commercialization: Some of the second-generation renewables, such as wind power, have high potential and have already realised relatively low production costs. Global wind power installations increased by 35,800 MW in 2010, bringing total installed capacity up to 194,400 MW, a 22.5% increase on the 158,700 MW installed at the end of 2009. The increase for 2010 represents investments totalling €47.3 billion (US$65 billion) and for the first time more than half of all new wind power was added outside of the traditional markets of Europe and North America, mainly driven, by the continuing boom in China which accounted for nearly half of all of the installations at 16,500 MW. China now has 42,300 MW of wind power installed. Wind power accounts for approximately 19% of electricity generated in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland. In Australian state of South Australia wind power, championed by Premier Mike Rann (2002–2011), now comprises 26% of the state's electricity generation, edging out coal fired power. At the end of 2011 South Australia, with 7.2% of Australia's population, had 54%of the nation's installed wind power capacity. Wind power's share of worldwide electricity usage at the end of 2014 was 3.1%. These are some of the largest wind farms in the world:
Document 13: Wind power in the United States: In 2016, Nebraska became the eighteenth state to have installed over 1,000 MW of wind power capacity. Texas, with over 20,000 MW of capacity, had the most installed wind power capacity of any U.S. state at the end of 2016. Texas also had more under construction than any other state currently has installed. The state generating the highest percentage of energy from wind power is Iowa. North Dakota has the most per capita wind generation. The Alta Wind Energy Center in California is the largest wind farm in the United States with a capacity of 1548 MW. GE Energy is the largest domestic wind turbine manufacturer.
Document 14: Geography of Nigeria: With the Intertropical Convergence Zone (ITCZ) swinging northward over West Africa from the Southern Hemisphere in April, heavy showers coming from pre-monsoonal convective clouds mainly in the form of squall lines also known as the north easterlies formed mainly as a result of the interactions of the two dominant airmasses in Nigeria known as the Maritime tropical (south westerlies) and the Continental tropical (north easterlies), begins in central Nigeria while the Monsoons from the south atlantic ocean arrives in central Nigeria in July bringing with it high humidity, heavy cloud cover and heavy rainfall which can be daily occurrence lasting till September when the monsoons gradually begin retreating southward to the southern part of Nigeria. Rainfall totals in central Nigeria varies from 1,100 mm (43.3 in) in the lowlands of the river Niger Benue trough to over 2,000 mm (78.7 in) along the south western escarpment of the Jos Plateau.
Document 15: Wind power in Iowa: Wind farms are most prevalent in the north and west portion of Iowa. Wind maps show the winds in these areas to be stronger on average, making them better suited for the development of wind energy. Average wind speeds are not consistent from month to month. Wind maps show wind speeds are on average strongest from November through April, peaking in March. August is the month with the weakest average wind speeds. On a daily cycle, there is a slight rise in average wind speeds in the afternoon, from 1 to 6 p.m. Estimates by the National Renewable Energy Laboratory (NREL) indicate Iowa has potentially 570,700 Megawatts of wind power using large turbines mounted on 80 meter towers. Iowa ranks seventh in the country in terms of wind energy generation potential due to the strong average wind speeds in the midsection of the U.S. The Iowa Environmental Mesonet distributes current weather and wind conditions from approximately 450 monitoring stations across Iowa, providing data for modelling and predicting wind power.
