A private business is lit by an electric generator while the rest of the building remains dark during a nationwide blackout in Havana on July 6, 2026. Cuba on July 6 suffered its third nationwide power outage since the start of the year, the state electricity company said. The impoverished island was already struggling to keep the lights on before US President Donald Trump in January imposed an oil blockade, which has depleted the already dwindling supply of fuel for Cuba's power plants.
