The most frequent questions I have seen about wind power is "what do you do if the wind isn't blowing?" This article answers that question, as well as another one. What do you do with the extra electricity when the wind IS blowing but electrical demand is down? The answer to both these is stored power, and there are a number of ways to do it including batteries, elevated water, generation of hydrogen, etc.

In 2011 rural MN rate payers lost $70 million JUST on the portion of wind electricity being produced at times when the utilities could not use it (and couldn't store it). MREA - what's the total for 2102? $135 Million? This piddling amount of environmentally dangerous battery storage isn't ready to even start to touch grid level storage needs. Maybe we could stop building wind turbines until after the major technical flaws are worked out. Or, we could continue our current practice of driving people from their homes, squandering $billions, and slaughtering birds and bats for a failed energy idea.
