This paper evaluates an intervention that randomized information letters about energy efficient investments and behaviors among 120,000 customers of two utilities in Germany. We find that conservation effects differ considerably between both utilities, ranging from a precisely estimated zero...

Rebates that reward economic agents if they meet a minimum conservation threshold are a popular policy to encourage energy conservation. However, most threshold-based rebates are structured such that they do not encourage reduction beyond the threshold. In this paper, I show theoretically that...
