Companies in Established Alternative-Energy Technologies

Large Companies in Established Alternative-Energy Technologies 

Many investors may already have exposure to alternative-energy companies in their investment portfolios without realizing it. For example, General Electric became a world leader in solar power this year when it took over AstroPower, adding to its position as a key player in the wind-turbine industry and providing equipment for the nuclear industry. The company announced earlier this year that it hoped to double its revenues by 2010 through the sale of environmentally cleaner technologies.38 

There are companies that offer purer plays in certain industries, specifically wind and solar energy.These include Vesta of Denmark and Gamesa of Spain in the wind-power industry, and Massachusetts-based Evergreen Solar in the solar sector. Stock prices for such companies often already reflect expected rapid rates of growth in these sectors of the energy market. If you are considering such an investment, you should consult your investment professional to determine whether it is a good time to purchase such a stock.
