Not to be too cynical but perhaps it’s more investment BABBLE than investment bubble. We’ve all seen this green energy nonsense come and go over the years and yet nothing ever makes it into the energy marketplace as a succesful competitor. No, the answer lies elsewhere for high energy density sources, it isn’t here.
I agree that it is investment babble, but it is babble that is not likely to stop anytime soon. The greens and their dim allies have plotted to partially nationalize the energy industry. These subsidies and mandates will lead to much higher energy prices and energy shortages. Without the subsidies and mandates, it would be an investment bubble. Ironically, the subsidies and mandates are increasing the cost of these alternative energy projects, in direct contrast to the claims of the alternative energy supporters. Without the mandates, the prices of alternative energy projects would be much lower.
I know you are kidding. You couldn't possibly thing windpower is a passing fancy.
