What do we know about the size of the rebound effect? Should we believe claims that energy efficiency improvements lead to an increase in energy use? This paper clarifies what the rebound effect is, and provides a guide for economists and policymakers interested in its magnitude. We describe how...

We use a unique dataset that combines the responses from an original survey of households, information about the structural characteristics of their homes, utility-provided longitudinal electricity usage records, plus utility program participation information, to study the uptake of energy...

We compare a range of energy efficiency policies in a durable good market subject to both energy-use externalities and price-quality discrimination by a monopolist. We find that the social optimum can be achieved with differentiated subsidies. With ad valorem subsidies, the subsidization of the...

We focus on two utility programs intended to reduce energy usage and the associated CO₂ emissions — a home energy audit and rebates on the purchase of high-efficiency air-source heat pumps. We use a unique panel dataset from participating and non-participating households to estimate the...

In addition to the already present Climate and Energy package, the European Union (EU) plans to include a binding target to reduce energy consumption. We analyze the rationales the EU invokes to justify such an overlapping and develop a minimal common framework to study interactions arising from...

Energy efficiency is one of the key crossroads between energy, climate and economic issues. In fact, it represents one of the most cost effective ways to enhance security of energy supply, to reduce emissions of greenhouse gases and to enhance economic competitiveness at one fell swoop. This...

Concerns about climate change are growing, and so is the demand for information about the costs and benefits of mitigating greenhouse gas emissions. This paper seeks to estimate the benefits of climate change mitigation, as measured by the public's willingness to pay for such policies. We...

We examine the effect of energy efficiency incentives on household energy-efficiency home improvements. Starting in February 2007, Italian homeowners have been able to avail themselves of tax credits on the purchase and installation costs of certain types of energy efficiency renovations. We...

We evaluate incentives for residential energy upgrades in Italy using data from an original survey of Italian homeowners. In this paper, attention is restricted to heating system replacements, and to the effect of monetary and non-monetary incentives on the propensity to replace the heating...

Energy efficiency is a foundation of any good energy policy. The economic, security, and environmental benefits of energy efficiency have been recognized for decades. We explore energy efficiency policy insights derived from survey work in developing countries in 119 projects across nine...
