Cuba faces blackouts as oil shortages threaten power, after U.S. actions cut imports.

Cuba is facing imminent nationwide power outages as oil reserves are expected to last only 15 to 20 days after Mexico halted a key shipment and the U.S. blocked Venezuelan supplies. President Donald Trump declared a national emergency and signed an executive order authorizing tariffs on countries supplying oil to Cuba, citing the island’s ties to Russia, China, Iran, and militant groups. With oil imports down to about 3,000 barrels per day in 2026, authorities warn of widespread blackouts and fuel rationing unless deliveries resume.
