Over the last two decades, U.S. households have received $47 billion in tax credits for buying heat pumps, solar panels, electric vehicles, and other "clean energy" technologies. Using information from tax returns, we show that these tax credits have gone predominantly to higher-income...

Residential natural gas customers in the United States face volumetric charges that average about 30 percent more than the marginal cost of gas. This inefficient departure from marginal cost pricing allows gas utilities to cover their fixed infrastructure and operating costs. Proposals for...

Residential natural gas customers in the United States face volumetric charges for natural gas that average about 30% more than marginal cost. The large markup on natural gas - which is used to cover the fixed infrastructure and operating costs of the local distribution companies - is widely...

Economic research on climate change has been crucial in advancing our understanding of the consequences associated with global warming as well as the costs and benefits of the various policies that might reduce emissions of greenhouse gases. As nations work to develop climate policies, economic...

One concern with subsidies for low-carbon technologies is that they tend to go predominantly to high-income households. Previous research has shown, for example, that the top income quintile receives 60% of subsidies for rooftop solar and 90% of subsidies for electric vehicles. This paper finds...

Since the 1970s, high volumetric (per kilowatt-hour) electricity prices have been justified in many policy discussions as encouraging more efficient use of electricity and placing more of the cost burden on those who are less prudent in their use. The argument has been used in support of...

The prospect for electric vehicles (EVs) as a climate change solution hinges on their widespread adoption across political lines. This paper uses county-level data to show that from 2012-2023, about half of all new EV registrations in the U.S. went to the 10% most Democratic counties. This...

Encouraged by the declining cost of grid-scale renewables, recent analyses conclude that the United States could reach net zero carbon dioxide emissions by 2050 at relatively low cost using currently available technologies. While the cost of renewable generation has declined dramatically,...
