Wind power in the United States is a branch of the energy industry that has expanded quickly over the latest several years. Texas, with over 22,000 MW of capacity, about 15% of the state's electricity usage, had the most installed wind power capacity of any U.S. state at the end of 2018. Texas also had more under construction than any other state currently has installed. The state generating the highest percentage of energy from wind power in Iowa, while North Dakota has the most per capita wind generation.
The American Wind Energy Association, a national trade association advocating for public policies friendly to the wind power industry, has gathered the data. It used turbines in place of a bar chart to indicate how much electrical capacity each state generates. Wind is a tricky thing to harness for electrical power, but there appears to be a correlation between the amount invested and total power returned.
Obtaining 20% from wind requires about 305 GW of wind turbines, an increase of 16 GW/year after 2018, or an average increase of 14.6%/year, and transmission line improvements. Analysts estimate around 25 GW of added US wind power in 2016-18, depending on the Clean Power Plan and PTC extensions. After the current PTC phase-out in 2021, additional wind power capacity is expected to be around 5 GW per year.
