retail store, which engineers predict will produce energy equal to or greater than it consumes. Walgreens plans to achieve that by utilizing solar panels, wind turbines, geothermal technology, energy-efficient building materials, LED lighting and ultra-high-efficiency refrigeration. The store will be located in Evanston, Ill. "We are committed to reducing our carbon footprint and leading the retail industry in use of green technology," said Thomas Connolly, Walgreens vice president of facilities development. "We are investing in developing a net-zero store so we can learn the best way to bring these features to our other stores. Because we operate 8,000 stores, we believe our pursuit of green technology can have a significant positive impact on the nation’s environment." The store plans to generate electricity and reduce its usage by more than 40 percent through several technologies in the store including: more than 800 roof-top solar panels, two wind turbines, geothermal energy obtained by drilling 550-feet into the ground below the store, where temperatures are more constant and can be tapped to heat or cool the store in winter and summer, LED lighting and daylight harvesting, carbon dioxide refrigerant for heating, cooling and refrigeration equipment, and energy efficient building materials.
