The first victim: The DirecTivo R10.
We dumped DirecTV a month ago. Thanks to Hulu and Netflix, DirecTV wasn't providing any service except Simpsons reruns. However, we had a couple dozen episodes of various shows on there, so we left it hooked up in case we got desperate for something to watch.
When it was actually driving a satellite dish, this box drew 26 watts. With the satellite disconnected, it draws 18 watts, 24 hours a day, 7 days a week--even in "standby" mode. Needless to say, that puppy got yanked tonight.
DirecTivo R10:
18 watts = 432Wh/day, 12.96kWh/month
Savings = $3.11/month, $37.32/year
