The American Gas Association (AGA) released a new study, Building for Efficiency: Home Appliance Cost and Emissions Comparison, that analyzes the relative impacts of natural gas and electric appliances in new construction homes. The study uses publicly available datasets from the U.S. Department of Energy, U.S. Energy Information Administration, and National Renewable Energy Laboratory Cambium Database to compare the cost, efficiency, and emission differences between residential appliances powered by natural gas and electricity.
