The state of Iowa has been tireless in their efforts to become more sustainable in the last five years, and now they have numbers to prove it. A press release from earlier this year says that up to 20% of Iowa’s electricity is produced by wind. The document is from the Iowa Policy Project.

The organization’s director, David Osterberg said of the trend, “In the last two years, Iowa added 2,500 megawatts of wind turbine capacity, and now has wind capacity nearly six times the size of Iowa’s lone nuclear plant.” Electricity prices in Iowa are also below the national average even though they have been investing in renewable technology, says the press release. Approximately 5% of Iowa’s electricity was generated by wind power in 2006.
