A new report from the American Wind Energy Association shows Kansas is leading the nation in the number of wind turbines under construction.

The wind industry's fourth-quarter report shows Kansas has 663 turbines under construction. The state tops the construction list with more than 1,188 megawatts of wind power scheduled to come on line this year.

Ohio ranked as the fastest-growing state in wind power last year. Texas still ranked first in the nation for overall wind power.

The U.S. wind industry installed 31 percent more megawatts in 2011 than the previous year.

Denise Bode, CEO of the American Wind Energy Association, says in a news release that the activity is driven by a federal production tax credit.
