TWINSBURG, Ohio (AP) — Upon entering Power Appliance, a store in a Cleveland suburb, Judy Sautner’s primary aim was to find a reliable yet affordable replacement for her daughter’s broken dryer.

“I wasn’t really worried about all the bells and whistles,” said Sautner.

According to Jay Buchanan, the store’s owner, many customers share Sautner’s priorities and often opt for appliances featuring the Energy Star label.

This U.S.-endorsed program asserts that its iconic blue symbol on energy-efficient appliances helps households save an average of $450 annually on their bills. Since its inception in 1992, Energy Star products have also averted 4 billion metric tons of greenhouse gas emissions, a leading factor in climate change.

But the program’s future is unclear. The Environmental Protection Agency has announced an agency reorganization plan that would eliminate its Energy Star offices. That would make it more difficult for customers to find energy efficient appliances. Here is a look at Energy Star along with tips to find energy efficient appliances if the program goes away:

How Energy Star works

Energy Star is a voluntary labeling program. The EPA sets energy efficiency standards for various machines, and then companies that produce them can try to hit or exceed those standards. If they do, they get the Energy Star sticker certifying it works as well as a standard product and uses less energy.

Companies are incentivized to make products that earn that sticker because state and local utility rebate programs, along with federal tax incentives, base qualifying appliances on the program. Consumers who want to save money through incentives and lower gas and electric bills know to look for it. And according to the program’s website, roughly 90% of households recognize the symbol.

Qualifying specifications vary depending on the appliance, but requirements include the amount of energy consumed when a machine is turned off, the inclusion of a low-power or “sleep” mode and a minimum efficiency rating when it’s operating.

If Energy Star goes away

Finding and buying energy-efficient products without that certification wouldn’t be impossible, just difficult, said Elizabeth Hewitt, associate professor of technology and society at Stony Brook University.

“You have to become a really savvy shopper,” she said.

It would mean consumers searching for, say, a dishwasher, would have to put together a list of options, gather specifications that come with each product, compare them, and recognize which numbers indicate that the dishwasher is energy efficient.

Specifications for a washing machine, for example, might include how many clothes can fit in a load, the gallons of water per load and the electricity required to run a cycle, while a furnace’s specs focus on how good it is at converting energy into heat, how much of that heat leaks and how well its fan does at blowing hot air into the house.

Converting all those numbers into a single seal of approval would be complicated.

“Unless they’re deep into analytics, they’re not gonna freakin’ know,” said Buchanan.

Buchanan said his customers usually ask for help finding energy efficient appliances. So if that seal of approval disappears, it’ll change his life more than the lives of his customers. He said he’ll have to do the work to figure out which appliances will save on energy bills.

The concern, said Executive Director Ben Stapleton with U.S. Green Building Council California, a nonprofit focused on sustainable building, is that extra set of steps will deter people from prioritizing energy efficiency.

“If we’re just relying on the manufacturer and relying on people to go through the manual to see what the power draw is, it’s hard to imagine that being effective,” he said.

Tips for picking appliances

Many utilities are incentivized to help households and businesses buy efficient appliances.

If Energy Star were to go away, utilities would need to figure out a new way of determining which appliances qualify for their incentive programs, said Mark Kresowik, senior policy director with the nonprofit American Council for an Energy-Efficient Economy. Calling and asking them about qualifying appliances would be a good place to start, he said.

Consumer Reports, an organization that does independent product reviews, can provide information about appliances and their performance, although it requires a subscription to access some of its more detailed information.

The Consortium for Energy Efficiency, a collaboration with primarily utilities, has its own energy efficiency standards. Right now those standards are designed with Energy Star in mind, but Kresowik said incentive programs could shift to using product specifications.

The fate of Energy Star is still uncertain. The broad reorganization at the EPA reported last month would eliminate or reorganize large parts of the offices that keep the program running, but the EPA has not directly confirmed a plan to shut it down or provided a timeline.

Regardless of what happens to Energy Star or what appliances are bought, Stapleton said consumers always have agency to use products in an energy-efficient way, such as washing clothes in cold water or avoiding the water-heavy dishwasher settings. It always helps to choose the right sized products.

“Maybe I don’t need the largest microwave that’s on the market,” he said.
