Intel, Microsoft and Apple are among the top 10 US companies sourcing their electricity from renewable energy sources.

The US Environmental Protection Agency has unveiled a list of the top 50 organisations that are choosing to use electricity from green sources.

The EPA defines green power as electricity produced from solar, wind, geothermal, biogas, eligible biomass and low-impact small hydroelectric sources.

Intel – which uses renewables to cover 100 per cent of its electricity load – came first, followed by Microsoft and Kohl’s department stores.

The rest of the top 10 were Whole Foods Market, Wal-Mart, the US Department of Energy, Staples, Starbucks, Lockheed Martin and Apple.

For the first time, the EPA also has released a list of partners that have committed to purchasing green power for a period of five years or more. Of the 47 partners on the list, 15 are higher education institutions. The EPA states that these organizations “send a strong signal to renewable energy developers, stating that they are committed to green power for the long-term”. Among the higher education institutions are the state universities of Oklahoma, Ohio and Iowa.
