Walmart, BMW Lead for On-site Renewable Energy Generation

Feb 11, 2013

Every quarter, the U.S. EPA updates its Green Power rankings for US businesses and communities making investments in clean, renewable energy.

One list we watch closely is the one that follows on-site generation, because it reflects direct investments, not just purchases of renewable energy credits (RECs).

Considering all its rooftop solar investments, it shouldn't surprise you all that much that Wal-Mart Stores tops the latest ranking. It now uses 174.8 million kilowatt-hours (kWh) of renewable energy at its US stores, generated by a combination of biogas, solar and wind. The No. 2 company on the EPA list, BMW Manufacturing,  gets an impressive 38% of the electricity it needs from on-site renewable generation sources (70.8 million kWh). It relies on biogas.
