Generating electricity with wind is supposed to reduce emissions by allowing coal fired power plants to be shut down. The idea is to replace electricity generated in coal plants with electricity generated by windmills. The problem is, we can’t shut down our coal plants, so the theory doesn’t work.
We can’t shut down our coal-fired power plants because we still need electricity when the wind isn’t blowing hard enough to turn the windmills. Can you imagine your power going off every time the wind slows down!?
