Myriad policy measures aim to reduce greenhouse gas emissions from the electricity sector, promote generation from renewable sources, and encourage energy conservation. To what extent do innovation and energy efficiency (EE) market failures justify additional interventions when a carbon price is...

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...

We analyze the cost-effectiveness of electric utility ratepayer-funded programs to promote demand-side management (DSM) and energy efficiency (EE) investments. We specify a model that relates electricity demand to previous EE DSM spending, energy prices, income, weather, and other demand...

Promoting energy efficiency (EE) has become a leading policy response to greenhouse gas emissions, energy dependence, and the cost of new generators and transmission lines. Such policies present numerous puzzles. Electricity prices below marginal production costs could warrant EE policies if EE...

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 enegy-efficiency equipment or building retrofits that would more than pay for themselves in terms of...

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...

Twenty states in the United States have adopted energy efficiency resource standards (EERS) that specify absolute or per¬centage reductions in energy use relative to business as usual. We examine how an EERS compares to policies oriented to meeting objectives, such as reducing greenhouse gas...

Energy efficiency resource standards (EERS) refer to policies that require utilities and other covered entities to achieve quantitative goals for reducing energy use by a certain year. EERS policies generally apply to electricity and natural gas sales and electricity peak demand, though they...

California will implement a cap-and-trade program to limit emissions of carbon dioxide covering industry and electricity sector emissions in 2013, expanding to cover transportation and natural gas in 2015. Although cap-and-trade would increase annual electricity costs for the average customer by...

The failure of consumers to make seemingly cost-effective investments in energy efficiency is commonly referred to as the energy efficiency gap. We review the most recent literature relevant to the energy efficiency gap and in particular discuss what the latest insights from behavioral economics...
