A glut of government-subsidized wind power may help accomplish a goal some environmentalists have sought for decades: kill off U.S. nuclear power plants while reducing reliance on electricity generated by burning coal, Bloomberg reported.

The new wind farms increased financial pressure on traditional generators such as Dominion Resources Inc. and Exelon Corp. in their operating regions. That's because wind energy undercut power prices already driven to 10-year-lows by an abundance of natural gas.

"Right now, natural gas and wind power are more economic than nuclear power in the Midwestern electricity market," Howard Learner, executive director of the Environmental Law and Policy Center, a Chicago-based advocate of cleaner energy, said in a phone interview. "It's a matter of economic competitiveness." Read more.
