ANY TIME THE WIND BLOWS:

Batteries at a Wind Farm Help Control Output (MATTHEW L. WALD, 10/29/11, NY Times)

The technology is young, and the finances are challenging. But the task of smoothing output, and the more ambitious one of storing many hours of electricity generated by wind production, seem likely to become ever more important as states require that a rising percentage of their electricity come from renewable sources.

The 13-state regional power grid that includes West Virginia, for example, has a capacity of 4,800 megawatts of electricity from the wind. But that number would grow eightfold if all of the states involved reached their renewable targets.
