The US Environmental Protection Agency (EPA) updates its rankings for businesses investing in renewable energy every quarter. Over the last quarter, Walmart and BMW have come out as leaders in renewable energy generation.
...it shouldn't surprise you much that Wal-Mart Stores tops the latest ranking. It now uses 174.8 million kilowatt-hours (kWh) of renewable energy at its U.S. stores, generated by a combination of biogas, solar and wind.
That's just one percent of its annual energy consumption, though.
The No. 2 company on the EPA list, BMW Manufacturing, actually gets an impressive 38 percent of the electricity it needs from on-site renewable generation sources (70.8 million kWh). It relies on biogas.
Coca-Cola Refreshments is third (47.5 million kWh, or 6 percent), followed by the U.S. Air Force (37 million kWh, which is less than one percent) and Kohl's Department Stores (36.5 million kWh, or two percent).
