Five or ten years ago, interest in Green energy sources was mainly found among environmentalists, not hedge fund managers or investment advisers. But with high energy prices and unrest in the Middle East, one financial expert says that it’s not just “ponytails,” but fancy business suits, that can be found at Green technology conferences. This, according to Grist magazine, which notes that in 2005, so-called clean energy projects were showered with $17 billion dollars in investment money – up nearly 90% from just the year before. Indeed, with everything from ethanol and wind to solar and geothermal seeing new infusions of cash, this could help renewables make more than just a dent on our energy needs.
