One concern I have w/respect to Germany's Feed In Tariffs, is that they may have gone too far. It is my understanding that they are now suffering from grid instability because they now have a significant percentage of wind generation.
Relatively speaking, Germany is a small country. When a large weather front moves thru, the wind generation shifts significantly, thus effecting grid stability. As they tie in to the surronding grids, that effect may be reduced.
