Des Moines, Iowa, recently played host to the American Wind Energy Association due to the state's ability to be the first state in the United States to generate at least 20 percent of electricity from wind power, according to Radio Iowa.

Currently, Iowa has more then 2,500 wind turbines that create more than 4,000 megawatts of electricity, and the state is looking to increase that output to 5,000 megawatts by the end of 2012, says the website.

"The transmission grid in the United States, as a whole, has not seen really significant upgrades in 50 years," Harold Prior, executive director of the Iowa Wind Energy Association, told the website. "We’re going to have to modernize the electrical transmission grid one way or another."

Two more wind projects have been approved in Iowa, North American Wind Power reports.

The Hawkeye Project will add 36 megawatts of energy to the power grid and will be located in Fayette County while the Rippey Project will supply 50 megawatts of energy and will be located in Greene County, according to the website.
