Computer chip giant Intel has retained its title as the largest purchaser of renewable energy in the US, topping the Environmental Protection Agency's (EPA) latest list of green power purchasers after buying more than 1.3 billion kilowatt-hours (kWh) of green energy last year.
According to the quarterly list, which was released yesterday, just under half the electricity Intel uses is generated by wind energy providers PNM and Sterling Planet - equivalent to the annual electricity usage of nearly 130,000 average US homes.
The Top 50 list was dominated by IT and retail firms, many of which have increased the amount of green energy they purchase in an attempt to meet internal carbon emission reduction targets.
Intel was joined in the Top 10 by PepsiCo, Kohl's Department Stores, Dell, Whole Foods Market, the Pepsi Bottling Group, Johnson & Johnson, the US Air Force, Cisco, and the City of Houston.
A number of high-profile firms also appeared in the Top 50 list for the first time, including Wal-Mart, Dannon, Sony and Motorola.
The list also featured a large number of state and city governments and federal agencies, including the City of Dallas, the City of Chicago, the US Department of Energy and the EPA itself.
The EPA said that overall, the Top 50 companies now purchase more than 11 billion kWh of green power annually, saving carbon emissions equivalent to that produced from the electricity use of more than 1.1 million average American homes.
The agency added that over 1,000 organisations have now signed up to its Green Power Partnership Programme, which helps businesses and public sector bodies procure renewable energy, either through renewable energy certificates, onsite generation or green energy tariffs.
