Each quarter, the U.S. Environmental Protection Agency updates its Green Power rankings for U.S. businesses and communities making investments in clean, renewable energy.
Wal-Mart Stores Inc. tops the recent list generating 174.8 million kilowatt-hours of renewable energy at its U.S. stores.
Environmentalists say the retail Goliath still has room for improvement as the renewable 174.8 million kWh is just about 1% of its annual energy consumption and 4% of its electricity needs.
Wal-Mart uses a combination of biogas, solar and wind initiatives at various stores around the country.
Other retailers on the list include Kohl’s Department Stores, which generates about 36.5 million kWh or 2% of its annual energy consumption but 105% of its electricity needs.
Whole Foods also ranks high among retailers generating 107% of its electricity needs by harnessing power from solar and wind.
