ACEEE’s rigorous research and advocacy help lower families' utility bills, reduce strain on the electric grid, and cut pollution.
Our experts have helped secure major progress in U.S. energy policy over the decades, from negotiating the first energy-saving standards for common household appliances in the National Appliance Energy Conservation Act—signed by President Reagan in 1987—to shaping the largest-ever federal investments in energy efficiency in 2022’s Inflation Reduction Act.
Today, families are feeling the squeeze of rising utility bills, and the U.S. energy system is straining under demand growth. Efficiency is the fastest, most affordable response, and it can be deployed at scale now. ACEEE provides analysis and practical insights to help policymakers, businesses, and local communities understand and act on efficiency opportunities that will provide lasting relief.

Our Initiatives
With the Appliance Standards Awareness Project, which is housed at ACEEE, we champion robust efficiency standards for appliances. Standards for new water heaters, for example, updated in April 2024, will save many households about $170 each year on utility bills, according to the U.S. Department of Energy.
The Chemical Catalyst Collaborative is a partnership of five organizations to advance technical and policy solutions that reduce toxic pollution and greenhouse gas emissions from the chemical manufacturing industry.
ACEEE's Energy Equity for Renters initiative helps tackle the challenge of reducing energy waste in rental housing. Our goal: protect the climate, reduce energy costs, and preserve affordable neighborhoods.
The Industrial Heat Pump Alliance is a collaborative effort that publishes research and convenes heat pump suppliers, end users, and other decision-makers to accelerate adoption of industrial heat pumps.
We collaborate with local governments and community-based organizations to ensure people of all income levels benefit from clean energy. Residential Retrofits for Energy Equity is our nationwide initiative that helps jump-start energy upgrades for affordable housing.
ACEEE in the newsA few of our favorite media highlights from the past month: |

| Through energy efficiency, the United States can halve domestic energy use and associated greenhouse gas emissions by 2050. This ambition, vital to preventing the worst effects of climate change, will not be realized without bold mobilization of efficient technologies and strategies. ACEEE is committed to meeting this urgent challenge. Our Call to Action lays out our vision for tackling climate change and the milestones we aim to reach by 2030. |
"ACEEE is needed more than ever on our carbon-challenged planet, so let’s do everything we can to make its next 40 years even more productive.” —Dan Reicher, executive director of Stanford University’s Steyer-Taylor Center for Energy Policy and Finance | “ACEEE has played an indispensable role in tracking [efficiency] progress, pointing to challenges and opportunities and keeping our eye on the prize: getting the biggest bang out of every dollar spent on energy.” —Susan Tierney, senior advisor, Analysis Group |
Where we've been
-
2010–2019
- Helped set new U.S. product efficiency standards, which will avoid three billion metric tons of carbon dioxide emissions by 2030 and save hundreds of billions of dollars.
- Led efforts to hike heavy-duty vehicle fuel economy standards, which will reduce average fuel consumption and greenhouse gas emissions of new trucks and buses by 37% from 2010 levels.
-
2000–2009
- Led efforts to establish CAFE provisions (2007) and heavy-duty fuel economy standards, spurring an increase in the average new car’s fuel economy from 20.6 miles per gallon in 2007 to 24.9 mpg in 2017, to a projected 36.0 mpg in 2025.
- Led efforts to expand appliance standards to 23 additional products, including light bulbs, through 2005 and 2007 U.S. legislation.
-
1990–1999
- Helped launch the voluntary ENERGY STAR® program, which helps consumers find energy-efficient products and improves the efficiency of buildings and homes.
- Led efforts to include lamp, motor, and HVAC standards in the Energy Policy Act of 1992, which will achieve cumulative energy bill savings of $340 billion by 2035.
-
1980–1989
- Led efforts to develop and adopt U.S. energy efficiency appliance standards, which now save a typical household about $500 each year on utility bills.
- Played key role in defending and expanding the Department of Energy’s energy R&D programs.
