I think it's fairly safe to conclude that both structural and cyclical factors have been at work in the recent declines of solar, wind, LED, and geothermal stocks. For the investor, the question should be, "Have the structural factors and most of the cyclical factors been fully priced in?" If so, these stocks will benefit as cyclical factors begin to reverse themselves. If, however, the full effects of the structural problems in these industries have yet to be felt, then even a political and cultural shift back towards pricing in the full costs of fossil fuels may not be enough to make the current batch of solar and wind stocks profitable again.
