The U.S. Environmental Protection Agency (EPA) has challenged Fortune 500 companies to double their green power purchases by the end of 2007, which could total to more than 5 billion kilowatt hours (that's enough energy to run more than 400,000 homes for a year).
On Monday, 40 companies accepted the challenge, including Wells Fargo (already the largest corporate purchaser of green power), Whole Foods (second largest), Johnson & Johnson (third largest), Cisco Systems, and Hewlett-Packard. Cisco and HP are not currently large purchasers of green energy, so their increases will be significant.
Number 1 and 2 on the Fortune 500 list, Exxon Mobil and Wal-Mart, have not accepted the challenge. Defend your honor, gentlemen!
On a related note, the growing influence of corporate leaders in the renewable energy markets will be explored at the Renewable Energy Marketing Conference in San Francisco this week. Business leaders, global warming experts, and renewable energy providers will discuss the future of the sector.
