Google has been completely carbon neutral since 2007—the same year the company installed the world’s largest corporate photovoltaic system at its Mountain View, Calif., campus. The company’s data centers are some of the world’s most efficient, requiring 50 percent less energy than average facilities. The centers are kept at a temperature of 80 degrees to reduce energy needs, and the company uses “free cooling” to remove heat from the center. Google claims that because of these steps, the carbon emissions from 1,050 Google searches are equivalent to those released by a glass of orange juice.
