Four companies account for more than half of all renewable energy sales across the U.S.: Sempra Energy, Pacific Gas & Electric (PG&E), Edison International and Xcel Energy all reported that more than 20 percent of their total energy sales came from renewable resources, according to a report from CERES. Combined, the four companies accounted for more than half of all renewable energy sales across the U.S.

Sempra Energy, owner of Southern California Gas Company and San Diego Gas & Electric, ranked highest for renewable energy sales with nearly 36 percent renewable energy sales.

PG&E was the only company to rank in the top five spots for all three indicators. PG&E ranked second for its percentage of renewable energy sales, at 25.9 percent of total sales, and second for its incremental energy efficiency with savings of 1.79 percent of total retail electric sales. The company ranked third for its life cycle energy efficiency with savings of nearly 18 percent.

The report analyzed the 2014 electric power generation sales of 30 of the largest U.S. investor-owned electric utilities, representing 119 subsidiaries in the U.S. Companies were ranked according to three indicators: Renewable energy sales, actual energy savings from company efficiency programs and estimated energy savings from all efficiency programs combined.
