Actually I understand it reasonably well: the wind blows, the turbine turns, electricity flows. That is the easy part.
The hard part to understand is this: why is wind powere not profitable? It seems doubtful to me that wind turbines should cost a lot more than steam or deisel turbines, and once in place there are no fuel costs. The wind is free, at least I always believed that.
Superficially it seems that wind should be a profitable energy source, but it apparently is not. What's the deal?
