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.
AGA also conducted a survey of their U.S. and Canadian members to assess the status and metrics of ratepayer-funded natural gas efficiency and low-income weatherization programs for the 2021and 2022 program years. The survey found that natural gas utility efficiency programs in North America continue to grow, diversify, and achieve energy savings. In 2022 alone natural gas efficiency programs saved 336 million therms of energy, roughly 1.7 million metric tons of avoided CO2 emissions. The report and associated appendices can be found on the AGA website here.
