Buildings account for roughly 40% of U.S. energy use. ACEEE advances the policies, codes, and programs that make homes and commercial buildings more efficient, from stronger building codes and appliance standards to weatherization programs that reduce energy costs for the households that need it most.
Transportation is the largest source of U.S. greenhouse gas emissions. ACEEE works to reduce those emissions through stronger vehicle standards, equitable EV charging infrastructure, smarter freight systems, and support for transit and communities that reduce vehicle miles traveled.
U.S. industry consumes roughly a quarter of the nation’s energy. ACEEE advances efficiency in industrial processes, supports electrification technologies like industrial heat pumps, and works to reduce the embodied carbon in the materials and chemicals that build our economy.
Utilities are on the front lines of rising electricity demand. ACEEE works with utilities, regulators, and policymakers to design programs and rate structures that treat efficiency and demand flexibility as central to a reliable, affordable, and clean grid.
Low-income households spend three times more of their income on energy than other families. ACEEE works to ensure that efficiency’s benefits reach renters, frontline communities, and households carrying the highest energy burdens, because that’s where the need and the impact are greatest.
How people use energy matters as much as the technology they use. ACEEE researches the behavioral science behind energy decisions and works to connect efficiency with health outcomes, from reducing indoor air pollution to improving the homes of people with chronic health conditions.
ACEEE’s independent research and advocacy depend on the support of foundations, businesses, and individuals committed to a cleaner, more affordable energy future for all Americans.
