Who won't need energy or water or food in the future?
Some companies make food, but are ethically questionable (ADM). Some make technology that doesn't sell (CPST). Some really have nothing to do with the earth's ecology but are cool because they make life nice for me (VLCM).
Although energy prices are high, nuclear power is still basically inexpensive... and coal so congressionally supported that wind and solar power companies (ESLR) have a difficult time..... Energy for cars? Hydrogen? I'm all for it, but as for investing.......I'm little wiser now.....Willie Nelson was just in the Wall Street Journal selling his new name brand BioWillie biodesiel....+ positive.
The thought of energy coming from somewhere besides oil sounds good to me. fuel cells?.
