ニューヨーク・タイムズさんのインスタグラム写真 - (ニューヨーク・タイムズInstagram)「Under new energy efficiency rules that took effect Tuesday, shoppers in the U.S. will no longer be able to purchase most incandescent bulbs. This marks the demise of a technology patented by Thomas Edison in the late 1800s. Taking their place are LED lights, which — love them or hate them — have already transformed America’s energy landscape. LED lights have driven down demand for electricity in American homes, saving people money. With people using less power, LEDs have also helped lower the nation’s emissions of greenhouse gases, which warm the planet and are a major cause of climate change. The new efficiency standard announced by the Biden administration requires light bulbs to meet a minimum standard of producing 45 lumens per watt. (A lumen is a measurement of brightness, and incandescents typically produce far less than that per watt.) An accompanying rule change applies the new standards to a wider universe of light bulbs. 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. Read the full story at the link in our bio. Photo by @maddiemcgarvey」8月2日 4時00分
