Energy efficiency is certainly not a concept unique to the United States. Indeed, some of the world’s leaders in energy efficiency reside in Europe, where high energy prices demanded deployment of energy efficient technologies and practices years ago. Although most of ACEEE’s work pertains to the United States, we also advise and assist energy efficiency centers and programs in key developing countries. Senior ACEEE staff have made long-term commitments to help Brazil, Thailand, and China in particular.

Beginning in 1983, we conducted studies of electrical conservation potential and helped establish a successful national electricity conservation program (known as PROCEL) in Brazil. With assistance from ACEEE, PROCEL developed and implemented numerous energy efficiency projects and minimum efficiency standards. In addition, we helped establish a nonprofit organization known as the National Institute for Energy Efficiency in Brazil.

Beginning in 1989, ACEEE has assisted the Thai National Energy Policy Office and other agencies to develop minimum efficiency standards, appliance labels, and demand-side management programs. In 1994, ACEEE began assisting the Beijing Energy Efficiency Center and other organizations in the People's Republic of China with the development of the China Green Lights Program and the China Motor Systems Energy Conservation Program. ACEEE helped advance the adoption of appliance efficiency standards in China as well. ACEEE has also assisted or supported energy efficiency efforts in India, Egypt, the Czech and Slovak Republics, Poland, and other developing countries.

In 2012, ACEEE released it's first International Energy Efficiency Scorecard
