70 regulations2026-02-19 Petroleum-Equivalent Fuel Economy Calculation, Interim final rule; request for comments
The federal government is updating how it measures fuel economy for vehicles that use alternative fuels like electricity or hydrogen. This change helps consumers and manufacturers understand and compare how efficient different types of vehicles are, making it easier to choose cleaner and cheaper transportation options.
2026-02-13 Energy Conservation Program: Energy Conservation Standards for Small Electric Motors; Final determination
The federal government has set new efficiency standards for small electric motors to reduce energy waste and lower electricity costs. These standards will apply to motors commonly used in household appliances, HVAC systems, and commercial equipment, requiring manufacturers to make them more efficient starting in 2026.
2026-02-13 Energy Conservation Program: Energy Conservation Standards for Metal Halide Lamp Fixtures; Final determination
The federal government is setting new energy efficiency standards for metal halide lamp fixtures, which are industrial and commercial lighting systems commonly used in warehouses, sports facilities, and outdoor areas. These standards will require manufacturers to make these fixtures use less electricity, reducing energy costs for businesses and lowering overall energy consumption nationally.
2026-01-08 Petroleum-Equivalent Fuel Economy Calculation; Final rule, technical amendment
The federal government is updating how it measures fuel efficiency for vehicles that run on alternative fuels like ethanol and electricity. This technical adjustment helps ensure that car manufacturers are accurately reporting how far these vehicles can travel on a gallon of fuel equivalent, which affects what cars are available to consumers and company compliance with fuel economy standards.
2025-09-09 Energy Conservation Program for Appliance Standards: Certification Requirements, Labeling Requirements, and Enforcement Provisions for Certain Consumer Products and Commercial Equipment; Final rule; Congressional Review Act (CRA) revocation
This regulation updates federal rules for how appliance and equipment manufacturers must test, label, and certify their products to show energy efficiency. The changes affect both the companies that make these products and consumers who buy them, as clearer labeling helps people understand how much energy appliances use and how much they'll cost to operate.
2025-09-09 Energy Conservation Program: Test Procedure for Central Air Conditioners and Heat Pumps; Final rule
This federal rule updates how the government tests central air conditioners and heat pumps to measure their energy efficiency. The new testing procedure will help ensure these machines are accurately labeled for how much energy they use, allowing consumers and businesses to make better choices about which cooling and heating systems save the most money on utility bills.
2025-09-03 Public Input on Energy Conservation Standards for Manufactured Housing; Request for information
The federal government is asking for public feedback on energy efficiency standards for manufactured homes (mobile homes and factory-built houses). These standards aim to reduce energy costs and environmental impact for the millions of Americans who live in manufactured housing by requiring builders to use more efficient heating, cooling, and insulation systems.
2025-07-02 Energy Conservation Standards for Manufactured Housing; Final rule
This regulation sets new energy efficiency standards for manufactured homes (mobile homes) to reduce energy waste and lower utility bills for residents. The standards require manufacturers to build these homes with better insulation, windows, and heating/cooling systems, making them cheaper to operate while reducing environmental impact.
2025-05-29 Energy Conservation Program: Test Procedure for Central Air Conditioners and Heat Pumps; Notice of proposed rulemaking and request for comment
The federal government is proposing new rules for how air conditioning and heat pump systems are tested to measure their energy efficiency. These tests help consumers compare how much electricity different cooling and heating systems use, so they can make informed choices and save money on their energy bills.
2025-05-27 Clean Energy for New Federal Buildings and Major Renovations of Federal Buildings; Correction; Final rule; stay; correction
This federal regulation requires that new federal buildings and major renovations of existing federal buildings must use clean energy sources like solar and wind power. The rule aims to reduce government buildings' carbon emissions and support the clean energy industry while potentially lowering long-term energy costs for taxpayers.
2025-05-20 Energy Conservation Program: Energy Conservation Standards for Commercial Refrigerators, Freezers, and Refrigerator-Freezers; Final rule; withdrawal
The federal government has withdrawn a proposed rule that would have set new energy efficiency standards for commercial refrigerators, freezers, and refrigerator-freezers used in stores and restaurants. By withdrawing this rule, the government is canceling the efficiency requirements it had been developing since 2017, meaning businesses will not be required to meet these new standards.
2025-05-20 Energy Conservation Program: Energy Conservation Standards for Walk-In Coolers and Walk-In Freezers; Final rule; withdrawal
The federal government has withdrawn a proposed rule that would have set energy efficiency standards for walk-in coolers and freezers used by businesses like restaurants and grocery stores. By withdrawing this rule, the government is canceling plans to require these commercial refrigeration units to use less electricity, which means businesses will not face new efficiency requirements in this area.
