Iowa is a leading U.S. state in wind power generation and electricity, with 5,133 MW of capacity (ahead of all states except Texas and California). Iowa produces 20% of all the electricity generated in the state from wind turbines, ranking it first in the nation and second in the world.
Spain has a robust and diverse renewable energy portfolio that has drastically reduced its reliance on fossil fuels. Spain imports more than 80% of its gas and coal for domestic consumption from overseas, making energy security a national priority.
Wind power has a long history in Texas. In 1970, West Texas State University began wind energy research which led to the formation of the Alternative Energy Institute (AEI) in 1977. AEI has been a major information resource about wind energy for Texas.
According to the American Wind Energy Association, as of the fourth quarter 2012, Colorado ranked tenth for wind power capacity with 2,301 megawatts (MW) installed. In 2006, Colorado only had 291 MW of capacity, despite a strong wind resource.
