Although wind energy now makes up 6.5% of the country's electricity supply, low natural gas prices and a phaseout of the production tax credit could put a brake on growth in coming years, according to a new Department of Energy report.
Prepared by the Lawrence Berkeley National Laboratory, the study found that wind added more than 7,500 megawatts of new capacity last year, with 20 states installing new utility-scale wind turbines.
Texas, where wind generated more electricity than coal through the first six months of this year, installed the most capacity in 2018, with more than 2,300 MW. Three states — Oklahoma, Iowa and Kansas — supplied between 31% and 36% of all in-state electricity generation.
Only natural gas and solar added more power than wind, the lab said.
