This paper explores the question of whether we should be encouraging or discouraging natural gas use in residential space-heating and water-heating applications based on relative source energy use. Our analysis finds that electric heat pumps generally use less energy in warm states and have moderately positive economics in these states if a heat pump can replace both the furnace and a central air conditioner. Moderately cold states can save energy if electricity comes from the highest-efficiency power plants, but life cycle costs for gas furnaces in existing homes will be lower than for heat pumps. In cold states, further development of cold-temperature electric heat pumps and gas-fired heat pumps will be useful.
Expanded utility-funded energy efficiency programs can significantly slow rising electricity demand and reduce electricity bills; this report explains how.
The commonwealth spends almost $11 billion a year buying energy from out of state. Mass Save lowers bills and keeps money at home.
This paper highlights a central lesson for policymakers: Industrial innovation requires alignment across government programs (grants, procurement), financing mechanisms (tax credits, loans), and institutional capacity. When these three are backed by sustained commitment from the public sector, private industry, and external stakeholders, the transition from demonstration to deployment becomes viable.
ACEEE’s independent research and advocacy depend on the support of foundations, businesses, and individuals committed to cutting energy bills, waste, and climate pollution.
