Energy Department Sets New Efficiency Standards for Microwave Ovens

June 5, 2013

The Energy Department announced on May 31 that it has finalized new energy efficiency standards for microwave ovens that will save consumers nearly $3 billion on their energy bills through 2030. Over the next 30 years, the reduction in greenhouse gas emissions due to the new standards will be equivalent to taking more than 12 million new cars off the road for one year.

The new standards for microwave ovens will reduce energy consumption in standby mode by 75% in counter-top microwave ovens and over-the-range microwave ovens without convection features, and by 51% for over-the-range microwave ovens with convection, preventing 38 million metric tons of carbon emissions over the next three decades. The present value of the net financial savings to consumers over the next 30 years is $3.4 billion. The standards will go into effect in 2016. See the Energy Department press release.
