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...

Displacing gasoline with a new source of biofuel, as California’s low-carbon fuel standard proposes to do, will reduce the global demand for oil. This will reduce the world oil price, which will cause an increase in oil use outside of California - the global rebound effect. Conventional wisdom...

Untapped improvements in energy efficiency in the residential sector may deliver large savings in energy use and the CO2 associated emissions. Yet empirical assessments have been difficult and controversial. We collect monthly natural gas meter readings from a sample of homes in Transcarpathia,...

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...

How can information substitute or complement financial incentives such as Pigouvian subsidies? We answer this question in a large-scale field experiment that cross-randomizes energy efficiency subsidies with information about the financial savings of LED lighting. Information has two effects: It...

How do private consumers adapt to changes to energy prices, in particular do they invest in energy-saving measures? We study this question in the context of the rapid rise in energy prices caused by the Russian invasion of Ukraine in February 2022 and the demand for energy efficiency in the UK...

Households reactions to efficiency gains in heating, known as rebound effects, are investigated in this article. First, an increase in temperature for households living in more efficient dwellings is studied (direct rebound). This increased temperature is then converted into energy following the...
