ACEEE has been working to support the development of energy efficiency technologies, programs, and policies for nearly 30 years, and has achieved many significant accomplishments, including:

Equipment Standards

Leading efforts to develop, promote, and negotiate appliance and equipment standards, including standards adopted by Congress in legislation in 1987, 1988, 1992, 2005, and 2007. Nearly 50 products are now covered by federal standards, with savings in 2010 from standards already adopted equal to more than 7% of 2010 U.S. electricity use.

Utility Energy Efficiency

Playing a major role in developing and implementing utility energy efficiency programs, which are now spending more than $2 billion per year and reducing U.S. electricity use by about 2.4%.

Federal Legislation

Playing a leading role in the development of energy efficiency provisions in the federal Energy Policy Acts of 1992 and 2005, the 2002 and 2008 Farm Bills, and the Energy Independence and Security Act of 2007.

State Consultation

Assisting many states with adopting and implementing energy efficiency policies and programs. For example, we played a leading role in helping to pass 2008 legislation in Maryland that commits the state to reducing electricity use by 15% by 2015. We continue to provide advice on strategies for meeting this target.

Policies and Programs

Tracking best practices in state and utility energy efficiency policies and programs.

Building Codes

Helping to develop model building codes for new homes and commercial buildings, which have been adopted in the majority of U.S. states.

Combined Heat and Power

Collaborating with many government officials, companies, advocates, and trade associations to advance programs and policies that encourage the use of combined and power systems (CHP) that cut energy waste in electricity generation by as much as half.

Transportation Efficiency

Initiating the first transportation efficiency program by a non-governmental organization, contributing to recent U.S. fuel efficiency standards for passenger vehicles and heavy-duty trucks, and also leading initiatives on efficiency in freight movement and strategies for reducing vehicle miles traveled.

Economic Analysis

Providing assessments of net jobs and other economy-wide benefits resulting from local, state, and national investments in energy efficiency improvements.


Supporting strong research and development programs at the federal and state levels, in order to develop the next generation of efficiency technologies and practices.


Issuing more than 300 publications on energy efficiency topics.

These steps, combined with efforts from our many allies, have helped slow the growth in U.S. energy demand since the 1970s. If energy use per dollar of Gross Domestic Product (adjusted for imports) were the same as in 1970, the United States would have used about 78% more energy than it actually consumed in 2010. In other words, energy efficiency is now our number one energy resource, accounting for more than 70% of what energy use would have been, had earlier technology and market trends remained static.
