$215B in annual energy cost savings starts with heat pumps: ACEEE

A new report from the American Council for an Energy-Efficient Economy (ACEEE), a research and advocacy group, says the country could cut energy costs by an average of $215 billion a year, adding up to $4.8 trillion by 2050, through a broad mix of efficiency upgrades. The biggest source of those savings: switching homes and buildings from gas furnaces and old electric resistance heating to heat pumps, which heat and cool a home using much less energy. The report estimates this cumulative savings works out to almost $31,000 per household by 2050.

The analysis assumes strong policy support, including a full switch to heat pumps for home heating by 2035, driven by incentives and efficiency standards, plus better building design, insulation, and controls in existing homes. About half of the projected 2050 savings would come from buildings, with heat pumps and other efficient appliances as the main driver. The rest comes from industrial efficiency, transportation improvements like better fuel economy and more electric vehicles, and demand flexibility programs that shift electricity use to off-peak times, which the report says could cut peak demand 20% by 2050.

The report notes that a federal building performance standard adopted in 2022 was revoked by the Trump administration last year. For homeowners, the broader message is that heating equipment choices, especially replacing an aging furnace with a heat pump, remain the single biggest lever for cutting both energy bills and strain on the power grid in the years ahead.
