The U.S. Department of Energy announced an agreement for new energy efficiency standards for commercial furnaces and rooftop air conditioners on Thursday.
The federal government called the standards the largest in U.S. history for the amount of energy that will be saved: nearly 15 quadrillion BTU over the next 30 years.
“They will save about the same amount of energy as all the coal burned in the U.S. to generate electricity in a year,” according to Rhea Suh, president of Natural Resources Defense Council. “These are very, very promising days in the global fight to slow, stop and reverse climate change.”
