As part of President Obama’s Climate Action Plan, the Energy Department announced a new energy efficiency standard for furnace fans. The new standard will help reduce carbon pollution by up to 34 million metric tons – equivalent to the annual electricity use of 4.7 million homes – and save Americans over $9 billion in home electricity bills through 2030, the department says. Last year, about 3 million furnace fans were shipped in the U.S. A standard furnace fan for a 70,000 Btu per hour furnace consumes roughly 1,000 kilowatt-hours per year, and the new standard could reduce energy use by 46 percent.
