The Senate Committee on Energy and Natural Resources heard testimony this week on the Energy Efficiency Reform Act, a bill that would significantly restrain the Department of Energy's ability to set efficiency standards for household appliances. The legislation targets appliances such as dishwashers and washing machines, which have long been subject to federal efficiency rules.

Under the proposed bill, updating existing efficiency standards would become far harder, and some older standards would be repealed outright. That marks a reversal of the usual process in which the DOE periodically tightens requirements to reduce energy use and consumer costs.

The hearing underscores the continuing political fight over appliance regulation. The outcome could shape how much authority the federal government has to require efficiency improvements in everyday household products.
