TIME: Ice Makers Are Destroying the Planet!

Want to save the Earth? Easy, just buy a couple of ice trays. To the long list of human inventions that are wrecking global climate—the internal combustion engine, the industrial era factory—add the automatic ice maker.

Climate modelers have long known that households are far bigger contributors to global warming than most laypeople realize. For all the blame tailpipe emissions take for escalating  temperatures, homes and office buildings are actually the single largest contributor to greenhouse gasses. One key reason is the 100-plus million refrigerators in America's 111 million households. According to the Department of Energy, the standard fridge sucks up about 8% of the electricity used by all homes—a pretty big share given the dozens of big and small appliances and electronics that are also drawing juice.

…the Department of Energy has announced that it intends to add 84 kilowatt hours to the efficiency rating of every refrigerator equipped with an icemaker. Consumers will feel that fact in the wallet—and if manufacturers don't scramble to improve their numbers, they soon will too.
