Walgreens to use geothermal power for store heating
(ADPnews) - Dec 30, 2010 - US drugstore chain Walgreens (NYSE:WAG) has opened an Oak Park-located store that uses geothermal power for heating and cooling.
The company said on Tuesday that the geothermal system will cut the store's energy usage by about 46%.
Set by geothermal systems developer Indie Energy, the installation harnesses the earth's heat utilising a network of four closed-loop boreholes installed at depths of 650 feet (198 metres), and a heat exchange system with the building that is controlled by Indie's EnergyLoop technology.
