Facing a deepening energy crisis exacerbated by U.S. sanctions and a halt in oil imports, Cuba is launching an ambitious, China-backed plan to transition 26 percent of its total energy supply to renewables by 2035.

China has become a major partner, providing financial support and expertise for large-scale projects like the La Herradura 1 wind farm and a plan to develop 92 solar parks by 2028, but the transition still faces major hurdles in funding (estimated at $8-10 billion) and a lack of skilled technical workers.
