New Efficiency Standards for Appliances Provide Cuts Equal to Removing 100 Million Cars

Cutting electricity use by dishwashers and refrigerators could save 550 million metric tons of CO2 over the next 25 years

Join Our Community of Science Lovers!

Major appliance makers and pro-efficiency groups have privately agreed on higher standards for the biggest energy users in the home, such as dishwashers and refrigerators.

The groups have written an agreement outlining these standards, and they will now take it to the Department of Energy, which sets energy standards for appliances every few years, U.S. EPA and Congress.

The Association of Home Appliance Manufacturers, or AHAM, represented the industry perspective in the talks. On the other side of the table were parties like the Natural Resources Defense Council, the Alliance to Save Energy and the American Council for an Energy-Efficient Economy -- major advocates for aggressive energy-efficiency laws.

The mix of players is notable because virtually everyone that would have shown up to the DOE proceedings essentially convened outside of that process.

DOE's procedure may seem arduous to some and thorough to others. After DOE proposes a standard, it takes formal input from industry, advocacy groups and the public. The procedure also combs through technical documents to try and find the maximum efficiency standard that causes the least economic harm.

All the information is compiled into documents that circulate among the interested parties again.

The process usually takes about three years, according to Andrew deLaski, executive director of the Appliance Standards Awareness Project, a pro-efficiency group.

A 3-year process completed in 3 months
DeLaski was also at the talks with AHAM, and he said this took about three months.

AHAM, like many other manufacturer groups, has sought to avoid a "patchwork" of regulations that lets some states require super-efficient appliances while others don't. A 1987 law sets up "federal pre-emption," so states can't set appliance standards higher than Washington does (ClimateWire, June 17, 2009).

DOE is scheduled to set new standards for many appliances in the next few years, including the home's biggest energy users: refrigerators, freezers, clothes washers and dryers, dishwashers and room air-conditioning units.

The agreement signed by AHAM and the other groups proposes higher standards for these appliances. Some will inch forward with 5 percent savings; others will leap ahead with almost 50 percent.

Refrigerators and freezers will use 10 to 30 percent less energy than current standards, depending on their type.

DeLaski said talking directly to the manufacturers also allowed energy-efficiency advocates to focus on the appliances that are the biggest sellers and the biggest energy users, and less on the small fish.

Emission cuts could be very large
The groups said the agreement, if adopted, would cut 550 million metric tons of CO2 over 25 years, the equivalent of taking 100 million cars off the road for a year.

Kevin Messner, AHAM's vice president of government relations, said these are the same groups it would have met at DOE anyway, but by meeting privately, there was more room for give and take.

A DOE rulemaking would zero in on a single question: for example, "What is the maximum energy a new refrigerator should use?" But by meeting with the other groups, AHAM roused support for a policy outside DOE's purview -- a tax incentive for manufacturers that they say is necessary to keep companies making super-efficient products.

"There's a lot more flexibility that we have because we're not constrained by the walls of the regulatory process," Messner said.

The groups agreed on another sweetener. EPA handles Energy Star, the program that defines and labels the most energy-efficient appliances available. Currently, since there is no smart grid, "smart" appliances that corral their own energy use have no additional label.

The groups will ask EPA to score these "smart" appliances as using 5 percent less energy than regular ones. DeLaski said there's no firm analytical reason for this number -- without a smart grid, no one knows just how much energy a smart appliance would save -- but it is an acceptable incentive to get manufacturers interested.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
