"Expanding Use of Wind Power Feasible, but May Be Costly"

"Wind could replace coal and natural gas for 20 to 30 percent of the electricity used in the eastern two-thirds of the United States by 2024, according to a study released Wednesday by the Energy Department.
But doing so would require a reorganization of the power grid and a significant increase in costs. And it would have only a modest impact on cutting emissions linked to global warming, the study found.

The Energy Department under President Obama has been a proponent of renewable energy, and the study tackles one of the biggest questions involving wind energy: How much can the power system use and still remain stable, given that the amount of electricity generated by wind turbines is as fickle as the breeze?"
