United States wind energy policy
There are currently 5,600 MW of projects under construction in 2011. The U.S. Department of Energy's 2011 report "20% Wind Energy by 2030" envisioned that wind power could supply 20% of all U.S. electricity, which included a contribution of 4% from offshore wind power.
MidAmerican Energy Company
In May 2018, MidAmerican Energy announced a new large-scale wind energy project called “Wind XII.” The project consists of 591 megawatts worth of energy created by wind in Iowa. Wind XII will make MidAmerican the first investor-owned electric utility in the United States to generate renewable energy equal to 100% of its customers usage each year.
