About Us


The American Council for an Energy-Efficient Economy (ACEEE),  a nonprofit, 501(c)(3) organization, acts as a catalyst to advance energy efficiency policies, programs, technologies, investments, and behaviors. We aim to build a vibrant and equitable economy – one that uses energy more productively, reduces costs, and promotes the health, safety, and well-being of all Americans.

ACEEE was founded in1980 by leading researchers in the energy field who were concerned about US dependence on foreign oil. Since then, by significantly improving energy efficiency across all sectors, the United States has halved its energy use relative to the size of the economy. Efficiency now saves more energy each year than the nation uses from any other single energy resource.

Despite this progress, the pace of climate change due to global energy use threatens our world’s well-being and compromises the global economy, our health and safety, and the ecosystems on which we depend. Energy efficiency is vital to mitigate the impacts of climate change. As the leading US center of expertise on energy efficiency, ACEEE is committed to ensuring that the United States reduces its domestic energy use and greenhouse gas emissions by 50% by 2050 while improving our nation’s economy and equity. More details on how we will reach this goal can be found here.

ACEEE has become known as America’s leading center of expertise on energy efficiency. Our reputation is based on the high quality, credibility, and relevance of our work, as well as our bipartisan approach. ACEEE’s thorough and externally-reviewed technical work is widely relied on by policymakers, business and industry decision makers, consumers, media, and other energy professionals. Working collaboratively with these groups, ACEEE can generate and promote solutions to today’s climate challenges. Our three-year strategic plan can be viewed here.
