Everybody's seen them. The photovoltaic (PV) panels that face the sun 
        and turn light into electrical energy. You can see them on emergency call 
        boxes, rural water pumps and a few eccentric homeowners who want to live 
        off the grid.'
      The game has changed. Now PV installations are covering entire rooftops 
        of large retail and industrial corporations. A combination of climate 
        awareness, energy efficiency, tax breaks and pure economics have spurred 
        several of the world's largest corporations to go green. Corporations, 
        schools and government buildings have large, flat roofs  providing 
        the perfect site for a solar installation. That power can supply the building 
        tenant, or be sold back into the grid to supply green electricity to other 
        customers. In most cases, this generation matches the need for peak power 
        during the day.
      Google, 
        Microsoft, Kohl's, Tiffany's, Target, 
        Wal Mart and Qualcomm are a few of the corporate leaders installing 
        rooftop solar. And there are other ways to make money and sense. Recently 
        PepsiCo pledged to offset 100% of the electricity used in U.S. facilities 
        by purchasing Renewable Energy Credits. Investment managers State Street 
        Global Advisors announced they are now buying green energy for their Boston 
        headquarters. 
      All of us use electrical energy in our daily lives. Imagine your grocery 
        store, local school, commercial and government buildings covered with 
        solar cells. Can you become a green energy customer through your local 
        utility? What if your city becomes a leader in promoting energy efficiency 
        and buying green power? Today, it's possible to make money and sense.
