Sustainable Energy for All (SE4ALL) is a global initiative led by the Secretary-General of the United Nations, Ban Ki-moon to achieve universal energy access, improve energy efficiency, and increase the use of renewable energy. It was launched to coincide with the designation of 2012 as the International Year of Sustainable Energy for All by the UN General Assembly in December 2010.

UN General Assembly resolution 65/151, which was passed on 20 December 2010, designated 2012 as the International Year of Sustainable Energy for All. This was in recognition of the growing importance of energy for economic development and climate change mitigation.
