How Much of Cuba's Energy Comes From Renewable Sources?

Though it is difficult to estimate exact numbers for Cuba’s energy use, due to the nature of the Cuban government, it is safe to say that while Cuba relies heavily on fossil fuels – and has its own offshore oil fields – it is making an effort to expand renewable energy endeavors. Solar heaters are sold in Cuba and used in many public facilities; a wind farm has been built on the Cuban island of Turiguano. Even Cuba’s maligned sugarcane industry is being put to good use: Biomass, energy produced from boiling sugarcane waste, is being used to produce power in Cuba.
