The Department of Energy, or DOE, announced Friday that it’s strengthening energy efficiency requirements for light bulbs in U.S. markets, in a move anticipated to save Americans $27 billion on their utility bills over 30 years. The DOE estimates that the new standards will prevent 70 million metric tons of carbon from being emitted over 30 years — equivalent to the annual emissions of 9 million homes.

Under the new standard, a light bulb as bright as an old-school 60-watt incandescent bulb would require no more than 6.5 watts of electricity.
The federal government has already once strengthened its efficiency standards under the Biden administration. Last year, the classic…
