More retailers using solar power

Chains such as Safeway, Whole Foods Markets and Wal-Mart, are pushing solar panel installation projects to gain a 30% tax credit. The US Energy Policy Act (EPAct) provides incentives for purchasing and using solar equipment “placed in service” from January 1, 2006 through December 31, 2008. Most chains have outfitted fewer than 10% of their stores so far.

Kathy Loftus, who is in charge of energy and other initiatives at Whole Foods Market, commented: "We're hoping that our purchases along with some other retailers will help bring the technology costs." If Congress renews the tax provision and more states offer incentives, the grocers promise to shift the solar construction program into high gear with panels on the roofs of almost every big store in the country.

Wal-Mart has 17 stores and distribution centers with solar panels currently operating or in the test phase. The chain is considering a larger program that would have panels and other renewable technologies at hundreds of its stores. In lieu of purchasing a solar-power system, big retailers like Wal-Mart can work with a utility company that will pay the up-front costs and give the grocer a break on power bills. "It really helps make it economical for the retailer," said Kim Saylors-Laster, Energy VP for Wal-Mart.
