The U.S. Department of Energy (DOE) has proposed energy efficiency requirements for the most common types of light bulbs, which conservation advocates believe will save consumers $300 million each month on their energy bills.
The rule would codify a “backstop,” or minimum efficacy standard, of 45 lumens per watt (lm/W) for general service lamps. DOE’s notice of proposed rulemaking hints at a “staggered implementation” to ease the burden on manufacturers, leading the American Council for an Energy-Efficient Economy (ACEEE) to question whether the Biden administration is moving rapidly enough to combat climate change.
DOE has also finalized a rule revising the agency’s appliance test procedure interim waiver process, which under former President Donald Trump was altered to allow greater flexibility for product manufacturers. Efficiency advocates say those changes allowed inefficient appliances to remain on shelves longer than necessary.
