In addition to higher electricity bills, energy-wasting electronics have a direct impact on the environment. After all, the average home is responsible for twice as much greenhouse gas as the average car, according to the EPA. In the U.S., power plants are responsible for 63 percent of all sulfur dioxide emissions and nearly 40 percent of carbon dioxide emissions, the agency said.
Tips from experts on how to curb consumer electronics' appetite for kilowatts
Look for the Energy Star label
This shows that a product meets the EPA's energy-efficiency criteria. The agency rates dozens of kinds of consumer electronics, including TVs, DVD players, stereo systems and home office equipment.
Ditch the screensavers
Screensavers require continuous processing power and prevent computers from resting in energy-saving "sleep" mode. That can add $50 to $100 to an electricity bill each year, if a PC is left on, the NRDC estimates.
Monitor improvements mean images can't burn into screens, so there's no need to use screensavers any more, the group says.
Unplug power adapters while not in use
Electricity continues to be eaten up by power adapters and chargers even when they're not recharging your cell phone, digital camera or other gadget.
Write your member of Congress
Let legislators know that you'd like to buy more energy-efficient electronics and urge quick action by the EPA and the Department of Energy on new specs for TVs and other devices.

"There's no smoke coming out of your TV when you turn it on," Durrett said. "So you have to think in terms of how that energy is made and how it gets to your home."
Energy Star push
Through its voluntary Energy Star labeling program, the EPA is hoping to encourage high-tech manufacturers to improve the energy efficiency of high-tech devices. On the power adapter front, the agency introduced Energy Star specifications earlier this year and has been working with cell phone manufacturers to implement them.
Samsung will be the first to sell handsets with Energy Star-qualified power adapters, EPA's Durrett said. Consumers should to see them arrive within the next few months, the agency said.
If every power adapter were 90 percent efficient, which the EPA said is possible, consumers could collectively save more than 5 billion kilowatt hours of electricity each year. The energy savings would prevent more than 4 million tons of greenhouse gas emission, equivalent to the average emissions of 700,000 cars, the agency said.
The EPA has also updated its Energy Star specification for computer monitors to address energy consumption while the machines are on. The previous specification deals mainly with sleep and off modes. Monitors sporting the new Energy Star label should start appearing early next year.
The agency is also working on an Energy Star specification for TVs that deals with the power consumed when the machines are on. The current TV specification only takes into account the power used in off-mode, which represents just 10 percent of TV energy use, according to NRDC data.
But the TV on-mode specification won't be ready for at least another two years, Durrett said. One big hurdle is coming up with a measurement method that manufacturers can agree on. The U.S. Department of Energy hasn't updated its method in nearly 30 years, so right now, it only applies to black-and-while TVs.
The NRDC is pressing for quicker action. "The time to act is now, before the sales of big-screen TVs take off due to price reductions," NRDC's Horowitz said. "If progress is not made soon, we will be stuck with a generation of energy-hogging big-screen TVs in people's homes for the next 10 years or so."
The group estimates that reducing active-mode energy consumption in TVs by 25 percent could save the U.S. more than 10 billion kilowatt hours a year, enough energy to power the state of Delaware for a year.

rid entirely of the Energy Star program.
If energy efficiency was ever an issue for anyone, makers would start competing over it and advertising it. Instead, nobody cares if your radio consumes 30W of power of 6W since a kilo (yep 1000) watt hour costs 8 cents.
How do you get the message across to the public though when they make their purchase decision. Their usual criteria is which box is the cheapest? Yes we could have procured a cheaper PSU adapter but it would have consumed another 1 or 2 watts. So another 50 cents to a dollar cost up for lower power could add another $5 at retail when you do the percentage mark-ups and sales tax etc.
The problem is when you add up the millions of boxes deployed you are talking 100's of megawatts when you account for multiple boxes in the home as well which is essential for Analog TV switch off.
So in the end every watt counts! It can be done and we try to do it without adding significant cost to the product. Also note that boxes which consume less power, run cooler and therefore tend to last longer which also helps the environment in terms of energy consumption in manufacture etc etc...
In the end it has to be a concerted effort between governments, retailers and manufacturers to get the message across to the public that they do have the choice if they want it to consume less power.

The only notable exception here in The Netherlands are cars and washing machines: they do have energy consumption class rating information attached to the product in showrooms and stores.
I doubt if that does influence decisions in case of a car, which is more about image than anything else, but I'm sure that in case of a washing machine energy consumption does play a mayor part in the consumer's mind when making a purchase decision.
I think that labeling the energy consumption for any electrical device would certainly help to make consumers at least aware of the after-sales cost they have to pay.
And if I ever will buy a setop box, I'll look for your products ;-)
doesn't seem to have a sleep function but even it's hard drive runs
all the time, which is inexcusable.
I've measured it at 21 watts when it's not doing anything.
*Based on 8 cents per kW/H, which is $0.00008 per watt hour * 24 hours * 366 days * 20 watts
there's no incentive for any politician to advocate saving energy
except in an election year so they can say "See? I'm environmentally
friendly!"
It's things like your dishwasher or oven that consume a lot.

- Yep. That's exatly what will happen if we're not careful. I'm 12. So guess what happens? The next generation has to deal with the stupity of energy wasters. Not a happy thought.
