Our efforts to help reduce greenhouse gas emissions and increase environmental awareness continued with the recent opening of new stores in San Francisco, Calif., and Quincy, Mass. Both stores feature rooftop energy-generation systems that use solar power, bringing Lowe's total solar locations to seven. We launched our first solar-panel rooftop systems at four California stores in 2004 and 2005, and installed a system atop our store in Kona, Hawaii, in 2008.
Lowe's solar systems together generated more than 3.5 million kilowatt-hours of electricity in 2010, enough electricity to power 320 homes* for an entire year.
*Estimate based on average annual electricity consumption of 11,040 kilowatt-hours provided by the U.S. Energy Information Administration.
