Dallas-based HKS Architects has offset 100% of annual electricity consumed at its 110,000-sq-ft corporate headquarters with the purchase of 4.3 million KW hours of renewable energy credits generated by wind farms across the U.S. through the Boulder, Colo.-based provider Renewable Choice Energy.
The EPA estimates that the purchase helps avoid a similar amount of CO2 emissions as produced by driving more than 4.8 million mi in an average car.
