In 2005, greenhouse gas (GHG) emissions from residential energy use hit an all-time high in the United States. Each year since, emissions have dropped at an average annual rate of 2 percent.
In a study published in Environmental Research Letters, “Drivers of change in US residential energy consumption and greenhouse gas emissions, 1990–2015,” a team of researchers from the Yale School of the Environment (YSE) outlined several factors that have contributed to this decrease, highlighting efficiencies in new home construction, energy consumption and household appliances, as well as less emissions in electric generation.
“Without the reductions in GHG intensity of electricity, residential GHG emissions would have been higher,” growing by 30 percent from 1990 to 2015 rather than the current 6 percent, says YSE PhD student Peter Berrill from the Center for Industrial Ecology, who co-authored the paper with Ken Gillingham, associate professor of economics at YSE, and former YSE faculty member Edgar Hertwich.
