Frequent power outages suggest the need for greater demand-side management.

This landmark work lauds the benefits of decreased energy consumption, investigating its relationship to public policy and analyzing its potential billion-dollar benefits to the U.S. economy.

U.S. consumers tend to use energy indiscriminately—something they may no longer be able to do with impunity. This game-changing book asserts that reducing energy consumption should be a frontline strategy to address global climate change, threats to energy security, and the challenge of grid reliability. The book supports two bold arguments: that policies motivating greater investment in high energy efficiency should be a priority, and that energy efficiency can help the nation in times of crisis.

To make their case for the necessity of prioritizing demand reduction, the authors examine the policies and markets operating in a number of leading cities, states, and nations across the globe to uncover the keys to their success. These examples show how demand-side strategies can significantly reduce pollution, cut costs, and make the electric grid more resilient. The authors explain why these technologies are not widely adopted and assess the potential savings they can produce. The book will be an eye-opener for policymakers, energy professionals, and the public as it demonstrates how cost-effective demand reduction policies can improve air quality, strengthen electricity markets, and generate jobs.

Marilyn A. Brown, PhD, is endowed professor in the School of Public Policy at the Georgia Institute of Technology, where she created and directs the Climate and Energy Policy Lab. She previously held leadership positions at Oak Ridge National Laboratory, where she became a national leader in the analysis and interpretation of scenarios for a sustainable energy future. Brown contributed to the reports of the Intergovernmental Panel on Climate Change (IPCC), which shared the Nobel Peace Prize in 2007 with Al Gore. In addition, she is a presidential appointee to the board of directors of the Tennessee Valley Authority, the largest U.S. public power corporation. She cofounded the Southeast Energy Efficiency Alliance and served on seven committees of the U.S. National Academies of Sciences. She has authored or edited more than 250 publications, among them Climate Change and Global Energy Security and Energy and American Society. In 2014, she received a Brook Byers Professorship, the highest title bestowed at Georgia Tech for those engaged in sustainability related research and education.

Yu Wang is assistant professor of global energy policy in the Department of Political Science at Iowa State University. She is an experienced modeler of the U.S. energy market, and was named the 2013 Outstanding PhD Student of the School of Public Policy at the Georgia Institute of Technology. Her research focuses on energy efficiency, renewable energy, and public policy analysis. Several sections of this book are derived from her dissertation research on U.S. Electric End-Use Energy Efficiency: Policy Impacts and Potential Assessment.


"Green Savings combines the theories, data, and policy analysis needed to understand energy efficiency. The case studies offer practical insights for entrepreneurs as well as policymakers at a range of scales on how to promote energy efficiency."—Nick Eyre, Program Leader in Energy and Associate Professor, Environmental Change Institute, University of Oxford

"A very useful book. Green Savings provides a thorough inquiry into energy efficiency, from market to policy, from technologies to productivity, from past performance to further potential, and from American states to global leaders. Its section responding to the views of skeptics is particularly strong."—Steve Nadel, Executive Director, American Council for an Energy-Efficient Economy

"A comprehensive and in-depth analysis of energy efficiency policies with intriguing state and country case studies. Considering energy efficiency as an important resource, Green Savings provides the insights and fundamentals you'll need as utility planners, city and state energy officers, and national leaders."—Clark Gellings, Fellow, Electric Power Research Institute
