This paper assesses trends in the global energy sector through 2040 by harmonizing multiple projections issued by private, government, and inter-governmental organizations based on methods from “Global Energy Outlooks Comparison: Methods and Challenges” (Newell and Qian 2015). These...

“Nudge”-style interventions are often deemed “successful” if they cause large behavior change, but they are rarely subjected to full social welfare evaluations. We combine a field experiment with a simple theoretical framework to evaluate the welfare effects of one especially...

Improving end-use energy efficiency—that is, the energy-efficiency of individuals, households, and firms as they consume energy—is often cited as an important element in efforts to reduce greenhouse-gas (GHG) emissions. Arguments for improving energy efficiency usually rely on the idea that...

Firms and governments often use moral suasion and economic incentives to influence intrinsic and extrinsic motivations for various economic activities. To investigate the persistence of such interventions, we randomly assigned households to moral suasion and dynamic pricing that stimulate energy...

Energy-efficient technologies offer considerable promise for reducing the financial costs and environmental damages associated with energy use, but these technologies appear not to be adopted by consumers and businesses to the degree that would apparently be justified, even on a purely financial...

There is limited evidence of behavioral changes resulting from electricity information feedback. Using a randomized control trial from a New York apartment building, we study long-term effects of information feedback from “Modlet” in-home devices, which provide near-real-time plug-level...

“Nudges” are being widely promoted to encourage energy conservation. We show that the popular electricity conservation “nudge” of providing feedback to households on own and peers' home electricity usage in a home electricity report is two to four times more effective with political...

By providing feedback to customers on home electricity and natural gas usage with a focus on peer comparisons, utilities can reduce energy consumption at a low cost. We analyze data from two large-scale, random-assignment field experiments conducted by utility companies providing electricity...

Starting in the 1970s California's residential electricity consumption per capita stopped increasing, while other states' electricity use continued to grow steadily. Similar patterns can be seen in non-electric energy, industry, and transportation. What accounts for California's apparent energy...

We evaluate the effectiveness of energy efficiency labeling in guiding household decisions. Using a carefully designed choice experiment with alternative labels, we disentangle the relative importance of different types of information and intertemporal behavior (i.e., discounting) in guiding...
