I didn't realize that it was OK to overstate numbers by an order of magnitude if it made for an interesting conversation

I'm going to try to get back to this and connect it with some other threads. For now though, consider it one more data point in the ongoing story of the challenges faced by people who try to correct falsehoods once they've made their way into the mainstream.

From Marketplace:

Could it possibly be true that watching videos on my smartphone uses as much electricity as two refrigerators?

“This is an example of a claim that sounds interesting, but really has no basis in fact,” says Jonathan Koomey, a research fellow at the Steyer-Taylor Center for Energy Policy and Finance at Stanford University.

Koomey has devoted years of his professional career to fighting this refrigerator analogy. It first came up more than a decade ago, by the same author, then making the claim that a Palm Pilot used the same electricity as a fridge.

Koomey says fighting it again now is pretty frustrating, “I’d rather not have to spend time rehashing this stuff.” But, the claim is back. So Koomey is back; figuring out just how much electricity goes into making and using my smartphone.

By his calculation, it’s about 60 kilowatt-hours.

Mark Mills, a senior fellow at the Manhattan Institute, and the author of the phone-equals-refrigerator claim, estimates it’s closer to 700 kilowatt-hours.

Mills is author of a report called The Cloud Begins with Coal, sponsored by the mining and coal industries. He says he wants to get people thinking about how much electricity these devices use. And he doesn’t think the controversy around the refrigerator analogy distracts people from his bigger point.

“The debate makes it an interesting conversation, like we’re having,” says Mills.

He stands by his calculations and his main assertion: “It is accurate: it uses a lot of electricity. Now if someone were to say, it’s not equal to a refrigerator or equals half a refrigerator or a tenth of a refrigerator, that’s still a big number.”
