Energy and Environmental Management (EAEM) Magazine
A survey by the Environmental Protection Agency based on consumption per year shows that global brands, including computer companies, topped the list in 2012.
Intel had the greatest use of renewable energy, with three trillion watt-hours of power: that’s 3 terawatt-hours (3TWh), which represents 100% of its electricity requirements.
Microsoft came second with 1.936TWh, but still sources one fifth of its electricity from conventional sources.
Apple came 10th in the list, with 537.4GWh, or 85% of its requirements.
