Cuba experienced a complete nationwide blackout on Tuesday, marking the third such event in just ten days. The recurring power outages are crippling the country and impacting daily life for all citizens. Officials attribute the crisis to ongoing issues with the National Electric System (SEN). A significant contributing factor is the decades-long U.S. oil embargo, which severely restricts Cuba's access to fuel needed to maintain the grid. These blackouts highlight the vulnerability of Cuba’s energy infrastructure and the challenges faced in providing consistent power. The situation raises concerns about economic disruption and public services. Restoration efforts are underway, but full recovery remains uncertain.
