The next fight over appliance efficiency is not about how many gallons a dishwasher uses or how much electricity a refrigerator consumes. It is about the rulebook Washington uses before it can set those numbers at all.
Connecticut, joined by energy officials from the District of Columbia, Maine and Washington, has opposed a Department of Energy proposal that would rewrite the federal “Process Rule” governing how future efficiency standards are developed. The states argue that the changes would make new or stronger standards harder to adopt and could ultimately raise household energy costs.
The state challenge follows a broader split over DOE’s July proposal. Efficiency advocates say the new framework would create barriers to standards with large long-term savings, while free-market groups argue DOE needs stronger guardrails to prevent rules that increase purchase prices or eliminate appliance features consumers value.
That dispute sounds procedural. For appliance makers, retailers and buyers, it is anything but. The Process Rule shapes how DOE evaluates future standards covering products ranging from refrigerators and dishwashers to washers, dryers, water heaters and cooking appliances.
What DOE Wants to Change
In its official Process Rule docket, DOE proposes to make parts of its rulemaking procedure binding on the department, restore a “walk-up” method for comparing efficiency levels, define what counts as significant energy savings, add economic thresholds and restore language requiring “clear and convincing evidence” for certain decisions.
The July 7 proposed rule says the changes are intended to increase certainty for affected parties and help the energy secretary determine both whether a product should be regulated and, if so, what standard level should be selected under the Energy Policy and Conservation Act.

One of the most consequential changes is the proposed return to a “walk-up” analysis. In simplified terms, DOE would begin at lower efficiency levels and move upward while testing economic justification and other statutory requirements. Critics argue that approach can stop the analysis before DOE reaches the most efficient level that might still be economically justified.
Why States Object
Connecticut officials framed their opposition around energy bills and the cumulative effect of federal standards. Their filing, described by the governor’s office and state energy regulators, argues that weakening the process for future standards would allow more energy use over the life of household products.
The policy argument is especially important because appliance efficiency is paid for in two places. A stricter standard can raise manufacturing costs or limit low-cost designs at the time of purchase, but lower energy or water use can reduce operating costs over years of ownership. Federal law requires DOE to weigh technological feasibility and economic justification rather than simply choosing the product that consumes the least energy.
The Institute for Policy Integrity, in separate comments filed Aug. 21, argued that DOE’s proposed numerical thresholds and walk-up methodology could block standards even when the lifetime consumer benefits exceed the costs. The group also challenged DOE’s treatment of environmental benefits.
Supporters See Consumer Choice and Regulatory Restraint
Opposition to stringent appliance rules has grown around a different consumer concern: whether federal standards make products more expensive, slower or less capable in pursuit of relatively small energy savings.
The Competitive Enterprise Institute, which supports the proposed direction, told DOE that the underlying appliance law contains consumer protections that should receive greater weight and that the department should be willing to decline new regulation when appropriate.
DOE itself says its proposal reflects federal policy emphasizing consumer choice and preserving appliance features. That is a materially different emphasis from an approach centered primarily on maximizing energy savings, and it helps explain why a seemingly technical change in regulatory procedure has drawn such polarized responses.
Manufacturers Also Want Predictability
The appliance industry has another concern that does not fit neatly into the political argument over efficiency: timing.
Six trade groups, including the Association of Home Appliance Manufacturers, asked DOE to extend the comment period because of the proposal’s scope and its relationship to a separate review of the analytical methods DOE uses to set standards. DOE granted a 15-day extension, moving the deadline from Aug. 6 to Aug. 21 rather than the Sept. 8 date the groups requested.
For a manufacturer planning a refrigerator or washer platform years before it reaches a showroom, regulatory predictability has a direct cost. Motors, compressors, insulation, controls and cabinet dimensions can all be affected by efficiency requirements. A standard that changes late in a product-development cycle can be expensive even when the company is capable of meeting it.
The Standards Landscape Is Already Moving
The Process Rule fight is occurring while individual appliance standards are already being challenged and reconsidered. Appliance News reported this week that a federal appeals court set aside DOE’s 2024 cooking-product efficiency standards, which had been scheduled to apply to newly manufactured or imported ranges, cooktops and ovens in 2028.
Congress is also considering legislation that would impose new limits on DOE’s standards process. Appliance News previously examined the Energy Efficiency Reform Act of 2026, which would put some of the same policy direction into statute rather than leaving it solely to agency rulemaking.
The result is a period of unusual uncertainty. Manufacturers cannot assume that standards adopted a few years ago will survive unchanged, and efficiency advocates cannot assume that the procedures used to write the next generation of rules will resemble those used for the last one.
What Consumers Should Watch
Nothing in the proposed Process Rule immediately changes the efficiency of a refrigerator or dishwasher already in a store. It changes the machinery behind future federal standards.
That distinction is important. Claims that the proposal has already increased household bills or eliminated existing appliance standards go too far. The more defensible conclusion is that the rule could change how readily DOE adopts stronger standards in the future — and therefore the balance between upfront appliance cost, product features and long-term utility consumption.
For an appliance buyer, that argument will eventually become concrete. It will show up not as a paragraph in the Federal Register, but as the refrigerator, washer or water heater available in the store — what it costs, what it can do and how much electricity or gas it uses for years after the receipt is gone.
