The U.S. Environmental Protection Agency’s (EPA) Green Power Partnership has recognized the participating organizations that generate the most “green” electricity on site. The Los Angeles County Sanitation Districts ranked second on the list. More than 50 percent of the electricity that the districts use is generated from biogas.

According to EPA, the top five organizations on the list use more than 535 million kWh of on-site green power and prevent carbon dioxide emissions equivalent to the emissions from more than 70,000 passenger vehicles per year.

“These companies are leading a nationwide move to the clean energy economy, one that can create million of jobs, reduce our dependence on foreign oil, and protect against global climate change,” said EPA Administrator Lisa P. Jackson in a press release. “Our Green Power Partnership leaders are setting the standard for our clean energy future.”
