Anyone know a good alternative energy stock to invest in?

Thinking about a retirement plan, looking to invest in a positive direction long term, aggressive growth acceptable....

LEDs are all the rage. The technology is advancing so rapidly, that it's hard to keep current.

I know this because we are trying to manufacture and sell high powered LED grow lights. By the time we get a design together, we have to change it because there's a new advance that we must incorporate.

BTW, we are looking for investors.

Global Green (GGRN) is a penny stock focused on "greensteam" landfill-gas energy. Buy it under a dime, not over $0.13. Valcent tech (VCTPF) has an algae-oil vertical growth system that produces far more oil/acre than any pond, but it appears pretty stagnant. They also have a vertical growth vegetable farming system that is now deployed in what I would call "pilot" installations. Could be big in the future for desert agriculture. But like I said, the stock is stagnant and has been since their horrid reverse split last year.

Maybe the best option is to pick a green mutual fund and let their experts make the picks. But the temptation to pick a penny and cross your fingers is great...

I've been researching....thinking maybe a green mutual fund is the best way...do you have any suggestions as to which one?
