Energy efficiency in buildings is crucial for climate change mitigation. Both national and state mandates increase energy efficiency, but most energy efficiency mandates in the United States are at the state level. The federal government mandates that its new buildings be energy efficient, and...

Energy efficiency provides a substantial opportunity to tackle increasing greenhouse gas emissions. However, in traditionally regulated energy markets, energy providers maximize their profits by selling electricity or heat as long as their marginal revenue exceeds their marginal costs of...

This paper measures energy efficiency improvements of US single-family homes between 1997 and 2001 using a two-stage procedure. In the first stage, an indicator of energy efficiency is derived by means of Data Envelopment Analysis (DEA), and the analogy between the DEA estimator and traditional...
