Popping the Clean Energy Fund Bubble Will Set the Stage for Future Growth

I don't think that graph accurately represents a bubble, because it doesn't represent money, it's just the number of ETFs and mutual funds devoted to renewable energy. And I'd say under 20 total is still a pretty small number. Some of these ETFs are pretty small (net assets in the funds less than $100M) and not very liquid. If you're trying to show that not all of these funds will survive, well yea, I agree with you there. But if you're trying to show that the renewable energy sector is somehow overvalued, I don't think that chart works at all. Show me something with the amount of $$ in these renewable energy funds or something, not just the number of funds.
