Despite growing enthusiasm, there is little empirical evidence on how well energy efficiency investments work. Evidence is particularly lacking from low- and middle-income countries, despite a widespread view that these countries have many of the best opportunities. This paper evaluates a field...

This article describes a household production model in which energy-efficient durable goods cost less to operate so households may use them more. The model is estimated using household level data from afield trial in which participants received high-efficiency clothes washers free of charge. The...

Electricity cannot be cost-effectively stored even for short periods of time. Consequently, wholesale electricity prices vary widely across hours of the day with peak prices frequently exceeding off-peak prices by a factor of ten or more. Most analyses of energy-efficiency policies ignore this...

"While public discussion of HR 2454 (the "Waxman Markey" bill) has focused on the cap-andtrade program that would be established for carbon emissions, the bill also includes provisions that would tighten energy efficiency standards for consumer appliances. Supporters argue that appliance...

This paper evaluates a field experiment in Mexico in which a quasi-experimental sample of new homes was provided with insulation and other energy efficient upgrades. A novel feature of our study is that we deploy large numbers of data loggers which allow us to measure temperature and humidity at...
