In 2018, an agreement between the key EU institutions - the Commission, the European Parliament, and the European Council - was reached after a long-lasting discourse over the 2030 EU climate and energy policy package. This paper offers a comprehensive assessment of the EU package, with its...

The effectiveness of investment subsidies depends on the existing array of regulatory and information mandates, especially in the energy efficiency space. Some consumers respond to information disclosure by purchasing energy-efficient durables (and thus may increase the inframarginal take-up of...

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...

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...

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...

Residential buildings are responsible for approximately 20 percent of U.S. energy consumption, and single-family homes alone account for about 16 percent. Older homes are less energy efficient than newer ones, and although many experts have identified upgrades and improvements that can yield...

We analyze the evaluations of California energy-efficiency programs to assess the effectiveness of these evaluations in: 1) improving our understanding of their performance and 2) providing a check on utility incentives to overstate energy savings. We find that third-party evaluations are useful...
