Oklahoma generated 15 percent of its electricity from wind in 2013, putting the state in seventh place nationally, according to new rankings released Wednesday.
The state moved up from No. 9 in 2012, when the share of electricity from wind was 10.5 percent. The rankings were compiled by the American Wind Energy Association using federal Energy Information Administration data.
Oklahoma remained in fourth place for the total amount of electricity generated from wind last year, although the total generated grew to 10.88 million megawatt hours from 8.23 million megawatt hours. Texas, Iowa, California and Oklahoma each generated enough electricity from wind to power more than 1 million homes.
The association said wind power topped 4 percent of the electricity on the U.S. grid for the first time last year. That made it the fifth-largest generation source, after coal, natural gas, nuclear and hydroelectric power.
“Wind energy continues to make inroads as a major contributor to the U.S. power mix,” said Elizabeth Salerno, vice president of industry data and analysis for the trade association. “The electricity generated by American wind power has more than tripled since 2008 not only due to significant growth in new wind projects, but also technology innovation leading to more productive turbines.”
In the Southwest Power Pool, the regional transmission organization that runs the grid in Oklahoma and parts of eight other states, wind made up 12 percent of electricity generated in 2013, the association said.
