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 phasedown of coal for electricity generation is considered vital to meeting global climate targets. Many countries have pledged to stop using coal, with some as early as 2030. While the United States has no target currently in place, several states do. In this paper, we examine the...

Environmental policy is increasingly concerned with measuring emissions resulting from local changes to electricity consumption. These marginal emissions are challenging to measure because electricity grids encompass multiple locations and the information available to identify the effect of each...

Green hydrogen may decarbonize sectors which are difficult to electrify, and the recent Inflation Reduction Act (IRA) provides tax credits to encourage hydrogen production. We analyze a model in which hydrogen produced using electricity replaces natural gas. The electricity may be procured from...

Electric vehicles have a unique potential to transform personal transportation. We analyze the transition to electric vehicles with a dynamic model that captures the falling costs of producing electric vehicles, the decreasing pollution from electricity generation, the increasing...

We determine the change in air pollution damages from U.S. power plant emissions over 2010 to 2017. Annual damages fell from $245 billion to $133 billion over this period, with most of the decline occurring in the East. Decomposition shows that changes in emissions rates reduced damages by $63...

The COVID-19 pandemic resulted in stay-at-home policies and other social distancing behaviors in the United States in spring of 2020. This paper examines the impact that these actions had on emissions and expected health effects through reduced personal vehicle travel and electricity...

We determine the environmental benefit of using electric buses rather than diesel or CNG for urban transit. For diesel and CNG we calculate air pollution damages by combining emission rates with damage valuations from the AP3 integrated assessment model and the social cost of carbon. For...

We examine the distributional effects of changes in local air pollution from driving electric vehicles in the United States. We employ an econometric model to estimate power plant emissions and an integrated assessment model to value damages in air pollution from both electric and gasoline...

Electric vehicles offer the promise of reduced environmental externalities relative to their gasoline counterparts. We combine a theoretical discrete-choice model of new vehicle purchases, an econometric analysis of the marginal emissions from electricity, and the AP2 air pollution model to...
