Question: Where does the state with the river of the same name, that is the mouth of the English River, rank in wind energy production?

full_context: Document 1: 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 2: 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 3: Elk River (Kansas): The Elk River is a tributary of the Verdigris River in southeastern Kansas in the United States. Via the Verdigris and Arkansas rivers, it is part of the Mississippi River watershed.
Document 4: 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 5: 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.
Document 6: New Haven, Connecticut: The city is drained by three rivers; the West, Mill, and Quinnipiac, named in order from west to east. The West River discharges into West Haven Harbor, while the Mill and Quinnipiac rivers discharge into New Haven Harbor. Both harbors are embayments of Long Island Sound. In addition, several smaller streams flow through the city's neighborhoods, including Wintergreen Brook, the Beaver Ponds Outlet, Wilmot Brook, Belden Brook, and Prospect Creek. Not all of these small streams have continuous flow year-round.
Document 7: 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 8: 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 9: Elk River (Oklahoma): The Elk River is a tributary of the Neosho River in southwestern Missouri and northeastern Oklahoma in the United States. Its tributaries also drain a small portion of northwestern Arkansas. Via the Neosho and Arkansas rivers, the Elk is part of the Mississippi River watershed.
Document 10: Tongue River (North Dakota): The Tongue River is a tributary of the Pembina River in northeastern North Dakota in the United States. It drains an area of the prairie country near the Canada–US border in the extreme northeast corner of the state in the watershed of the Red River.
Document 11: Minnesota River: The Minnesota River is a tributary of the Mississippi River, approximately 332 miles (534 km) long, in the U.S. state of Minnesota. It drains a watershed of nearly , in Minnesota and about in South Dakota and Iowa.
Document 12: River Yeo (South Somerset): The River Yeo, also known as the River Ivel, is a tributary of the River Parrett in north Dorset and south Somerset, England.
Document 13: Boone River: The Boone River is a tributary of the Des Moines River in north-central Iowa in the United States. It is long and drains an area of . Via the Des Moines River, it is part of the watershed of the Mississippi River.
Document 14: English River (Iowa): The English River is a tributary of the Iowa River in southeastern Iowa in the United States. The main stem of the river is long. Including its longest headwaters tributary, the North English River, the total length increases to . Via the Iowa River, it is part of the Mississippi River watershed. The Deep River is a minor tributary of the English River. The towns of North English, South English and Deep River are named for the English and Deep rivers.
Document 15: 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.
