All the vampire metaphors in the world aren't making vampire power consumption less of a problem.
The answer, probably, is yes. Good magazine made an awesome graphic about this a while ago, showing what it might be costing you. According to one Cornell University study, you might have as many as 20 vampires lurking in your house, and your PlayStation or your plasma TV or your computer--they're only the start. That same study found that "your TV with remote control likely uses more energy during the 20 hours a day that it’s turned off and in a 'standby power' state than it does during the hours you watch the tube."
What to do about that is in dispute, between the California Energy Commission and consumer electronics companies, and their fight just got a little bit bigger.
If you're worried about vampire power sucking consumer electronics, you don't have a lot of options. You can religiously unplug everything and turn it off, but that won't work for your TiVo, which goes through a lengthy re-boot after being powered down. Investor-owned utilities like PG&E make a moderate-sized deal of recommending Energy Star appliances. But the Federal EnergyStar and EnergyGuide labels aren't required on consumer electronics. So all that useful information EnergyGuide requires, "an estimate of the product's energy consumption or energy efficiency...the highest and lowest energy consumption or efficiency estimates of similar appliance models." Optional for consumer electronics.
It what sounds like one surreal eco-horror flick, the state of California’s Energy Commission has declared war on “vampire” chargers that greedily suck electricity and drive up utility bills. Citing the statistic that up some chargers waste up to 60% of the electricity they consume, I can’t stop glaring at my cable box. But I digress.
California is actually the first state to adopt such measures, with the Commission voting 3-0 to lay the smack down on said charging units, even amidst the expected objections including some from the Association of Home Appliance Manufacturers. Given the number of chargeable devices that currently litter our lifestyles, it’s a move that’s right one time, if not overdue.
The new regulations (which require the products consume less energy while providing the same services) kick in on February 1, 2013, and are projected to save enough energy annually to power a city the size of Bakersfield, not to mention a whopping $306 million for ratepayers.
