The Energy Revolution was a campaign through which Cuba attempted to decarbonize its economy. It was announced by Fidel Castro on July 26, 2005, in the wake of massive disruption to Cuba's electric grid during Hurricane Dennis, during a speech commemorating the attack on Moncada Barracks. The campaign attempted to decentralize Cuban electricity infrastructure. It replaced durable household goods with more energy efficient models, and increased the use of renewable energy resources. However, As of 2026, Cuba remains dependent on imported oil. Cuba burns 100,000 barrels of oil daily to supply electricity, with small contributions from other sources.
