2006 was "The Year of the Energy Revolution" in Cuba. Government Ministries and NGOs developed a nationwide plan focused on energy efficiency and independence. The entire electrical system was upgraded, efficient appliances were distributed among the citizenry, and cadres of young social workers went from house to house in every community teaching energy efficient methods of home maintenance. Cuba became the first country in the world to completely phase out incandescent light bulbs.

During 2006 - 2007 Cuba saved close to one million tons of imported oil through these measures, and reduced their CO2 emissions by 5 million tons.
