There’s extra federal funding than ever to chuck fossil fuels out of houses, due to the historic 2022 Inflation Reduction Act, which incorporates $4.5 billion in focused rebates to impress the home equipment of low- and moderate-income households. That quantity isn’t practically sufficient to cowl the price of retrofitting the roughly 36 million lower-income U.S. households that warmth with gasoline, propane, and oil — estimated at $625 billion, in keeping with Nadel. But it’s a down cost, he mentioned.
To decide the consequences of prioritizing electrification for lower-income households, the examine authors modeled two very totally different futures during which 75 p.c of U.S. residential vitality use is inspired by 2050. In one situation, lower-income households lag far behind higher-income counterparts and solely about half have electrified. In the opposite, they’ve stored tempo and 80 p.c have electrified by midcentury.
The first situation would total find yourself costing $88 billion, the staff discovered, whereas the second would end in web financial savings of about $96 billion via decreased utility payments. Moreover, accounting for the social and well being impacts, equitable electrification would yield $140 billion extra in advantages than an inequitable strategy.
The staff estimated these prices and advantages of electrifying lower-income households by drawing on constructing traits and vitality use knowledge for a consultant pattern of greater than 18,000 houses from the U.S. Energy Information Administration’s 2020 Residential Energy Consumption Survey. The authors additionally relied on federal sources and instruments to mannequin the social impacts of greenhouse gases and outside air air pollution.
The authors concluded that switching households to heat-pump water heaters and heat-pump HVAC methods delivers the best advantages. ACEEE recommends policymakers promote these swaps first.
Still, the largest hurdle to electrifying lower-income houses is that “it’s not low cost,” Nadel mentioned. “Some kind of public financing will likely be crucial.” To assist cowl the upfront prices, states will possible want to drag from a mixture of sources, he mentioned, such because the tax base, the federal authorities, and cap-and-invest applications that put a value on carbon and use the income for carbon-slashing initiatives. The societal advantages of those public investments, he famous, can pay off.
