The journal aims to publish articles that will serve several goals: to synthesize and integrate lessons learned from active lines of economic research; to provide economic analysis of public policy issues; to encourage cross-fertilization of ideas among the fields of economics; to offer readers an accessible source for state-of-the-art economic thinking; to suggest directions for future research; to provide insights and read- ings for classroom use; and to address issues relating to the economics profession . Articles appearing in the journal are normally solicited by the editors and associate editors . Proposals for topics and authors should be directed to the journal office, at the address inside the front cover . Policy on Data Availability It is the policy of the Journal of Economic Perspectives to publish papers only if the data used in the analysis are clearly and precisely documented and are readily available to any researcher for purposes of replication . Details of the computations sufficient to permit replication must be provided . The Editor should be notified at the time of submission if the data used in a paper are proprietary or if, for some other reason, the above requirements cannot be met . Policy on Disclosure Authors of articles appearing in the Journal of Economic Perspectives are expected to disclose any potential conflicts of interest that may arise from their consulting activities, financial interests, or other nonacademic activities .

Hunt Allcott and Michael Greenstone any analysts of the energy industry have long believed that energy effi ciencyciency offersoffers anan enormousenormous “win-win”“win-win” opportunity:opportunity: throughthrough aggres-aggres- M sive energy conservation policies, we can both save money and reduce negative externalities associated with energy use. In 1979, Pulitzer Prize-winning author Daniel Yergin and the Harvard Business School Energy Project made an early version of this argument in the book Energy Future: If the United States were to make a serious commitment to conservation, it might well consume 30 to 40 percent less energy than it now does, and still enjoy the same or an even higher standard of living . Although some of the barriers are economic, they are in most cases institutional, political, and social. Overcoming them requires a government policy that champions con- servation, that gives it a chance equal in the marketplace to that enjoyed by conventional sources of energy. Thirty years later, consultancy McKinsey & Co. made a similar argument in its 2009 report, Unlocking Energy Effi ciency in the U.S. Economy : Energy effi ciency offers a vast, low-cost energy resource for the U.S. economy— but only if the nation can craft a comprehensive and innovative approach to ■ Hunt Allcott is Assistant Professor of Economics, New York University, New York City, New York.

Signifi cant and persistent barriers will need to be addressed at mul- tiple levels to stimulate demand for energy effi ciency and manage its delivery . If executed at scale, a holistic approach would yield gross energy savings worth more than $1.2 trillion, well above the $520 billion needed through 2020 for upfront investment in effi ciency measures (not including program costs). Such a program is estimated to reduce end-use energy consumption in 2020 by 9.1 quadrillion BTUs, roughly 23 percent of projected demand, potentially abating up to 1.1 gigatons of greenhouse gases annually. In economic language, the “win-win” argument is that government interven- tion to encourage energy effi ciency can improve welfare for two reasons. First, the consumption of fossil fuels, which comprise the bulk of our current energy sources, causes externalities such as harm to human health, climate change, and constraints on the foreign policy objectives of energy-importing countries. Second, other
