You could look into some geothermal companies (hot rock energy - greenhouse gas free). The one I invested in is GDY but there are a few others that look good too. Also, check out some rare earth companies. Rare earths are used to make very efficient electric motors used just about everywhere from photo copiers to cars and busses etc. There is a lot of rare earth in every hybrid car. The rare earth company I like (and have shares in) is ARU (which was given a buy recommendation in the latest Dines Letter that came out this weekend).
