Four Ways The Solar Boom Has Rattled Utilities Sept 24 2013

The push for green energy in the United States may be hindered by the limitations of our outdated power grids, which are unsuited for unpredictable energy sources like sunlight and wind, according to Los Angles Times’ Evan Halper.

The current grid system is designed to “keep the supply of power steady and predictable,” Halper writes. But energy from renewable sources isn’t steady and can’t be controlled — a windy day could overload the system, while sudden cloud cover above a solar field would make it hard to keep the lights on. . . .

This isn’t a reason not to invest in green energy, since our aging and over-stretched power grid is already in need of an expensive upgrade. . . .
