Solar Energy Is Up - But Wind Power Is Also Surging

Why does no one want to talk about what we do for power on a cloudy, still day? This means that there has to be back up equal to the wind or solar capacity. This is a major impact on the cost of both. Until there is a way to store the electrical energy efficiently, solar and wind will not become mainstream.

U.S. Wind Power Doubles to More Than 20 Gigawatts in Two Years

The achiles heel of wind and solar power is a cloudy day with no wind requiring back up power generation capable of filling the void. This aspect is not talked about when the economics of green power is discussed. It does make sense when the product of the electricity can be stored ie. desalination. Presently, there is not an economic solution to storing electricity.
