The U.S. Environmental Protection Agency's (EPA) proposed greenhouse gas (GHG) performance standards for power plants are an important step forward in regulating GHGs in terms of both their substantive impact and legal precedent. Nevertheless, we have some concerns with the proposal, which we...

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...

Despite several decades of government policies to promote energy efficiency, estimates of the costs and benefits of such policies remain controversial. At the heart of the controversy is whether there is an "energy efficiency gap," whereby consumers and firms fail to make seemingly positive net...

Three types of policies that are prominent in the federal debate over addressing greenhouse gas emissions in the United States are a cap-and-trade program (CTP) on emissions, a renewable portfolio standard (RPS) for electricity production, and tax credits for renewable electricity producers....

Commercial and residential buildings are responsible for 42 percent of all U.S. energy consumption and 41 percent of U.S. CO2 emissions. Engineering studies identify several investments in new energy-efficiency equipment or building retrofits that would more than pay for themselves in terms of...

The electricity sector is responsible for roughly 40 percent of U.S. carbon dioxide (CO2) emissions, and a shift away from conventional coal-fired generation is an important component of the U.S. strategy to reduce greenhouse gas emissions. Toward that goal, several proposals for a clean energy...

In this paper, we introduce a new top-down approach to modeling the effects of publicly financed energy-efficiency programs on electricity consumption and carbon dioxide emissions. The approach draws on a partial-adjustment econometric model of electricity demand and represents the results of a...

Building energy use accounted for 38 percent of total US carbon dioxide (CO2) emissions in 2012, and roughly half of those emissions were attributable to the commercial building sector. A new policy that has been adopted in 10 US cities and one US county is a requirement that commercial and...

Substantially reducing carbon dioxide (CO2) emissions from electricity production will require a transformation of the resources used to produce power. This paper analyzes the economic consequences of a suite of different flexible and comprehensive policies to reduce CO2 emissions from the power...

To investigate how fuel economy is valued in the Indian car market, we compute the cost to Indian consumers of purchasing a more fuel-efficient vehicle and compare it to the benefit of lower fuel costs over the life of the vehicle. We use hedonic price functions for four market segments (petrol...
