Attorney General Becerra Fights to Protect Cost-Saving Energy Efficiency Standards for Consumers and Small Businesses SACRAMENTO – California Attorney General Xavier Becerra today joined a lawsuit challenging two final rules promulgated by the U.S. Department of Energy (DOE) during the final days of the Trump Administration as part of its longstanding effort to undermine our nation’s energy efficiency program. The rules would protect gas-powered residential furnaces and commercial water heaters from tougher energy efficiency standards – standards that would apply if they were in the same category as electric powered products. The rules would deny consumers and businesses over $30 billion in savings over the next 30 years.
