Hey NY Times, now do an article on clothes dryers which use 4x more energy than the BTC network[1][2] while air-drying can do it without any electricity.
Or try to estimate how much power the current financial industry takes, hint: it's not exactly a small scale operation. But while the motive for attacking BTCs might not always be honest (see this article also has no shame in casually calling out the early adopters of Bitcoins as "anarchists"), the point about energy consumption isn't entirely invalid. Right now it's probably on the line of being fine, but it a puts a real hard cap on how much further BTC will be able to scale. We definitely can't have another 10x increase in power consumption or something like this. So maybe protocol changes are needed, or things will slowly shift somewhere else, just something to keep in mind.
