Cuba’s energy crisis has reached critical levels as the island nation struggles to withstand a US blockade on oil imports used for power and transport. Cuba’s outdated, oil-dependent electricity grid now faces constant blackouts, especially after domestic reserves of diesel and fuel oil ran out in mid-May. Power plants burning domestically produced oil and natural gas, alongside solar capacity ramped up over the last two years, provide short windows of electricity supply during the day. The country has continued to import Chinese solar equipment in 2026 to further build out capacity, but has a long road to free itself from oil imports.
