What's wonderfully convenient, almost on a can't-live-without-it level, but horribly wasteful of electricity? Your DVR. DVRs consume $3 billion in energy a year, and most of it is while they're turned off. Or don't you notice that the thing keeps humming away and the hard drive keeps rattling? Can't they go into sleep mode and wake up when needed like laptops can? (Los Angeles Times)
