The confluence of several pending environmental rulemakings will require billions of dollars of investment across the industry and changes in the operation of facilities. These changes may lead to retirement of some facilities, and there has been much debate about their potential effects on...

Several recent studies have used simulation models to quantify the potential effects of recent environmental regulations on power plants, including the Mercury and Air Toxics Standards (MATS), one of the US Environmental Protection Agency’s most expensive regulations. These studies have...

The Regional Greenhouse Gas Initiative is an effort by nine states to constrain carbon dioxide emissions from the electric power sector using a cap-and-trade program. This paper assesses the importance of long-term electricity contracts under the program. We find that 12.2% of generation will be...

The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter—arguably, the number-one environment-related public health threat facing the nation. We present an...

For years economists have urged policymakers to use market-based approaches such as cap-and-trade programs or emission taxes to control pollution. The SO2 allowance market created by Title IV of the 1990 U.S. Clean Air Act Amendments (CAAA) presents the first real test of the wisdom of...

We investigate the cost-effectiveness and distributional effects of a revenue-raising auction, grandfathering, and a generation performance standard as alternative approaches for distributing carbon emission allowances in the electricity sector. We solve a detailed national electricity market...

We analyze policies to promote renewable sources of electricity. A renewable portfolio standard raises electricity prices and primarily reduces gas-fired generation. A “knee” of the cost curve exists between 15% and 20% goals for 2020 in our central case, and higher natural gas prices lower...

The Regional Greenhouse Gas Initiative (RGGI) is an effort by nine Northeast and Mid-Atlantic states to develop a regional, mandatory, market-based cap-and-trade program to reduce greenhouse gas (GHG) emissions from the electricity sector. The initiative is expected to lead to an increase in the...

Policies to cap emissions of carbon dioxide (CO2) in the U.S. economy could pose significant costs on the electricity sector, which contributes roughly 40 percent of total CO2 emissions in the U.S. Using a detailed simulation model of the electricity sector, we evaluate alternative ways that...
