About Us +
Researchers in EAEI focus on three broad areas: Energy Markets, Policy, and Infrastructure; Energy and Environmental Systems Analysis; and Appliance and Equipment Energy Efficiency Studies.

We develop analytical and experimental methods and tools to assess the technical, economic and market potential of energy technologies, as well as the associated social, economic, health and environmental impacts.

EAEI researchers provide unbiased, scientific, high quality and innovative research and technical assistance to government agencies in the United States and throughout the world. We help these entities develop long-term strategies, policies and programs that facilitate energy efficiency and the deployment of clean energy technology with minimum environmental and health impacts in all sectors and industries.
