The US oil blockade has triggered severe fuel shortages and nationwide blackouts across Cuba, but the energy crisis is simultaneously driving one of the world's fastest solar energy buildouts, financed heavily by China — with Cuban solar imports from Beijing jumping from $5 million in 2023 to $117 million in 2025. The core facts are well-sourced and confirmed across multiple outlets, though the framing somewhat softens the humanitarian impact (devastating blackouts for 10 million people) by emphasizing the silver lining of accelerated renewable deployment. The omitted context: how long this transition will take to actually resolve the immediate blackouts, and whether the pace of solar buildout can outrun ongoing electricity shortages in the near term.
