Neither rule is an explicit ban on incandescents. And a few specialized kinds of incandescent bulbs — like those that go inside ovens, and bug lights — are exempt. But most if not all other incandescents will struggle to meet the new efficiency standards, and the same goes for a more recent generation of halogen lights. “Energy-efficient lighting is the big energy story that nobody is talking about,” said Lucas Davis, an energy economist at the Haas School of Business, part of the University of California, Berkeley. “Going from an incandescent to an LED is like replacing a car that gets 25 miles per gallon with another one that gets 130 m.p.g.,” he said. With the new rules in place, the Department of Energy expects Americans to collectively save nearly $3 billion a year on their utility bills. In the past, a knock on LEDs was that they were more expensive to buy, but prices for LED bulbs have fallen rapidly to near parity with incandescents. The cost savings could come as a boost particularly to lower-income households, which spend a larger proportion of their income on utilities. Research has shown that retailers in poorer neighborhoods had also been among the slowest to phase out energy-guzzling bulbs. Over the next three decades, the rules will also cut carbon dioxide emissions by 222 million metric tons the Energy Department said, which it compared to the emissions from 28 million homes in one year.
