Well, perhaps we might get the kind of investment we need in clean energy after all. Business Week reports on how green is Wall Street's new darling:

You know a cultural movement is real when the money men get on board. In just the past year a broad swath of financiers -- venture capitalists, hedge funds, investment banks, public pension funds, and even stodgy insurers -- have begun sinking billions of dollars into producers of ethanol, fuel cell superbatteries, microscopic bugs that turn glucose into plastic, environmentally friendly pesticides, anything that might tap into the green craze. Saving the planet, protecting America, doing God's work, cynically exploiting a feel-good trend -- call it what you will. Wall Street sees money to be made.
