The World Resources Institute has corralled several prominent companies (think General Motors, IBM, Johnson & Johnson, and Kinkos) into expanding their use of renewable energy. The group hopes that a coalition of companies will commit to using 1,000 megawatts of renewable electricity by 2010; so far, companies in a dozen states have signed on to use 15 MW of power. IBM said yesterday that its use of renewable power and energy efficiency measures had helped the company cut carbon dioxide emissions by 28 percent in the last decade. Kinkos said it now buys a total of 4.2 million kWh of renewable power per year at 80 of its stores nationwide.
