The Inflation Reduction Act (IRA) represents the largest federal response to climate change to date. We highlight the key climate provisions and assess the Act's potential economic impacts. Substantially higher investments in clean energy and electric vehicles imply that fiscal costs may be...

We categorize the primary incentive-based mechanisms under consideration for addressing greenhouse gas emissions from electricity generation--pricing carbon, setting intensity standards, and subsidizing clean energy--and compare their market outcomes under similar expansions of clean electricity...

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,...

Effective and economical expansion of renewable energy is one of the most urgent and important challenges of addressing climate change. However, many countries are facing a problem because existing network infrastructures (i.e., transmission networks) were not originally built to accommodate...

We investigate the short- and long-term effects of a natural gas boom in an economy where energy can be produced with coal, natural gas, or clean sources and the direction of technology is endogenous. In the short run, a natural gas boom reduces carbon emissions by inducing substitution away...

Many US states have set ambitious renewable portfolio standards (RPS) that require utilities to switch from fossil fuels toward renewables. RPS increases the renewables capacity, bond issuance, maturity, and yield spreads of investor-owned utilities compared to municipal producers that are...

We study how the implementation of emissions trading systems (ETS) impacts emissions reductions and the usage of renewable energy using a panel sample of the largest 100 countries worldwide. Exploiting the cross-country variations in ETS implementations, we show that ETS adoption materially...

Decarbonization and electrification will require a transformed electricity grid. Our long-run model of entry and exit of generation and storage capacity captures crucial aspects of the electricity industry such as time-varying demand for electricity, intermittency of renewables, and...

The U.S. regulation of high-voltage transmission is highly complex and, as a result, generally poorly understood. The complexity is created by separate, but overlapping, jurisdictional authorities of the U.S. federal regulators and those of individual states, districts, and territories. While...

Natural gas has replaced coal as the dominant fuel for U.S. electricity generation. However, U.S. states that regulate electric utilities have retired coal more slowly than others. We build a structural model of rate-of-return regulation during an energy transition where utilities face tradeoffs...
