Study Finds Costs of Residential Energy Efficiency Investments are Double the Benefits

Energy efficiency improvements are central components of several major energy policy initiatives globally and a core pillar of most long-term carbon abatement strategies. However, there is a gap between the uptake of efficiency measures and their perceived attractiveness based on projected costs and benefits.

To explore these issues, a research team from the University of Chicago and the University of California, Berkeley, conducted a first-of-its-kind field test of one energy efficiency program: the Federal Weatherization Assistance Program. The analysis was based on a randomized controlled trial conducted with a sample of more than 30,000 households in the state of Michigan. Such experiments are considered the gold standard for evidence.
