In 2017 Argentina and Romania accessioned to NEA as its most recent members. Together they account for approximately 85% of the world’s installed nuclear capacity. Nuclear power accounts for almost a quarter of the electricity produced in NEA Member countries. The NEA works closely with the International Atomic Energy Agency (IAEA) in Vienna and with the European Commission in Brussels. Within the OECD, there is close co-ordination with the International Energy Agency and the Environment Directorate, as well as contacts with other directorates, as appropriate.

At the Heiligendamm Summit in June 2007, the G8 acknowledged an EU proposal for an international initiative on energy efficiency tabled in March 2007, and agreed to explore, together with the International Energy Agency, the most effective means to promote energy efficiency internationally. A year later, on 8 June 2008, the G8 countries, China, India, South Korea and the European Community decided to establish the International Partnership for Energy Efficiency Cooperation, at the Energy Ministerial meeting hosted by Japan in the frame of the 2008 G8 Presidency, in Aomori.
