The Biden administration finalized energy efficiency regulations targeting common everyday lightbulbs late Friday, as part of its sweeping climate agenda.
The Department of Energy announced the new standards for general service lamps, which include the most common types of residential and commercial lightbulbs. The agency said the regulations will slash greenhouse gas pollution, ultimately cutting 70 million metric tons of dangerous carbon dioxide over the next three decades.
“Making common household appliances more efficient is one of the most effective ways to slash energy costs and cut harmful carbon emissions,” Energy Secretary Jennifer Granholm said in a statement.
“Under President Biden and as directed by Congress, DOE is following the lead of lightbulb manufacturers, helping American families flip the switch on massive energy savings through strengthened energy efficiency standards.”
In addition to its projected emissions reductions, DOE said the new lightbulb efficiency standards will save American families $1.6 billion in household energy costs every year.
Under the rules, which will be implemented beginning in mid-2028, manufacturers will be mandated to raise the efficiency level of most common lightbulbs from 45 lumens per watt to more than 120 lumens per watt, a nearly 170% increase. Only LED bulbs will be able to comply with the standards, not compact fluorescent bulbs.
While U.S. households have increasingly switched to LED light bulbs since 2015, fewer than half of households reported using mostly or exclusively LEDs, according to recent results from the Residential Energy Consumption Survey.
Overall, 47% of households use mostly or only LEDs, 15% use mostly incandescent or halogens, and 12% use mostly or all compact fluorescent, with another 26% reporting no predominant bulb type, the federal data showed.
