The Roscoe Wind Farm in Roscoe, Texas, owned and operated by E.ON Climate & Renewables is one of the world's largest capacity wind farms with 634 wind turbines and a total installed capacity of 781.5 MW. At the time of its completion in 2009, it was the largest wind farm in the world, surpassing the nearby 735.5-megawatt Horse Hollow Wind Energy Center.In 2012, it was overtaken by California's 1,020-megawatt Alta Wind Energy Center.
Roscoe is a city near the intersection of Interstate 20 and US Highway 84 in Nolan County in the U.S. state of Texas. The Union Pacific Railroad passes through the center of the city. Another rail line, the Roscoe, Snyder and Pacific Railway (RS&P), used to extend 50 miles (80 km) from Roscoe to Fluvanna, passing through Snyder, Texas. Built in 1908, the railway served as a bridge between the Atchison, Topeka and Santa Fe Railway and the Texas and Pacific Railway. Although the RS&P became one of the most profitable short lines in the nation during its early years, passenger service was discontinued in 1953, freight service was discontinued in the late 1970s, and the tracks were removed in 1984. Roscoe is now home to the Plowboy Mudbog which is held twice a year, during the Independence Day Celebration, which is held on July 4 weekend, and in October, usually coinciding with the Wind Festival. The July mudbog normally draws around 70 to 80 trucks competing for prize and bragging rights.
E.ON SE is a European holding company based in Essen, North Rhine-Westphalia, Germany. It runs one of the world's largest investor-owned electric utility service providers. The name comes from the Greek word aeon which means age. The company is a component of the Euro Stoxx 50 stock market index, DAX stock index and a member of the Dow Jones Global Titans 50 index.
A wind farm or wind park is a group of wind turbines in the same location used to produce electricity. A large wind farm may consist of several hundred individual wind turbines and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm can also be located offshore.
Roscoe was constructed in four phases. The first phase, Roscoe, was constructed in 2008 and consists of 209 Mitsubishi 1-megawatt turbines. Phase two is called Champion was also completed in 2008 and includes 55 Siemens 2.3-megawatt machines. The third phase is called Pyron. Its 166 GE 1.5-megawatt turbines were commissioned in mid-2009 shortly before the fourth phase, Inadale, was completed. Inadale adds 197 more Mitsubishi 1-megawatt turbines to the existing project.
The project cost more than $1 billion and provides enough power for more than 250,000 average Texan homes. It is located about 200 miles (320 kilometres) west of Fort Worth, spanning parts of four Texas counties and covering nearly 100,000 acres (40,000 ha), several times the size of Manhattan.
Cliff Etheredge, a local cotton farmer, helped to organize the project. In addition to its large size, the farm is also notable for the large number of individual land owners (as many as 400) who share in royalties from the project. Wind farms are helping to revive the local economy in remote areas of West Texas and the Texas Panhandle.
The Texas Panhandle is a region of the U.S. state of Texas consisting of the northernmost 26 counties in the state. The panhandle is a rectangular area bordered by New Mexico to the west and Oklahoma to the north and east. The Handbook of Texas defines the southern border of Swisher County as the southern boundary of the Texas Panhandle region.
The Roscoe Wind Farm and Cliff Etheredge are featured in the 2010 documentary film, Carbon Nation.
Carbon Nation is a 2010 documentary film by Peter Byck about technological- and community-based energy solutions to the growing worldwide carbon footprint. The film is narrated by Bill Kurtis. ASIN: B0055T46LA (Rental) and B0055T46G0 (Purchase).

Wind power in the United States is a branch of the energy industry that has expanded quickly over the latest several years. For the twelve months through November 2017, 254.2 terawatt-hours were generated by wind power, or 6.33% of all generated electrical energy.
Wind power in Texas consists of many wind farms with a total installed nameplate capacity of 22,637 MW from over 40 different projects. Texas produces the most wind power of any U.S. state. According to ERCOT, wind power accounted for at least 15.7% of the electricity generated in Texas during 2017, as wind was 17.4% of electricity generated in ERCOT, which manages 90% of Texas's power.
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. As of 2008, Blue Canyon remains Oklahoma's largest wind farm; however, several organizations including Oklahoma Gas & Electric plan to greatly increase Oklahoma's wind power capacity, and future projects may be larger.

The US state of Colorado has vast wind energy resources and the installed electricity capacity and generation from wind power in Colorado has been growing significantly in recent years. The growth has been sustained due to a combination of falling costs, continuing federal incentives, and the state's aggressive renewable portfolio standard that requires 30% of the state's electricity to come from renewable sources by 2020.
