Appliance efficiency has increased remarkably over the past several decades. The graph below tracks the energy efficiency of four household appliances over a 35-year period. Three of the products (clothes washers, central air conditioners, and refrigerators), show a 50% or greater reduction in energy use over that period, and the fourth product, gas furnaces, shows a smaller but still significant reduction of 18%.
The final few weeks of 2015 proved busy ones for new national appliance and equipment standards. The Department of Energy (DOE) completed the biggest energy-saving standard in agency history, along with several important but lower-profile standards which will collectively yield large energy and economic savings. Some of them point the way to much larger future savings.
The past year included many successes, including quite a few that we can build on in the new year. Among the notable developments in 2015:
Yesterday, the Department of Energy (DOE) issued two rules affecting ceiling fans: a proposed rule that would establish the first efficiency performance standards for ceiling fans, and a final rule that improves the efficiency of the lights attached to ceiling fans.
Standards the result of negotiations among broad group of stakeholders
Washington, DC—Energy efficiency standards issued today for rooftop air conditioners and heat pumps—which represent the largest energy and pollution savings of any rule ever issued by the Department of Energy—will benefit businesses, manufacturers, and the environment, according to four of the organizations that participated in the negotiations leading to the announcement.

Late yesterday, the Department of Energy (DOE) proposed strong new standards that would reduce the energy consumed by beverage vending machines to keep drinks cold. The proposed standards would cut energy use by 25-65% relative to the least-efficient machines available now, and save money for schools, hospitals, hotels, and other businesses and institutions where beverage vending machines are used.
