Cuba experienced a nationwide blackout after its national energy grid suffered a total collapse. The energy ministry confirmed the complete disconnection of the electrical system on social media, plunging the island and its population of approximately nine million residents into darkness. The severe failure stems from a combination of chronic fuel shortages, decades of underinvestment, deteriorating Soviet-era infrastructure, and a tightening U.S.-imposed oil embargo that has heavily choked off essential petroleum imports. Authorities have launched restoration efforts, prioritizing essential facilities such as hospitals and water treatment plants through isolated micro-networks. However, the system remains highly unstable and vulnerable to repeated failures following numerous major blackouts over recent months. The ongoing energy crisis continues to severely disrupt basic public services, communications, and daily economic activity across the country, intensifying humanitarian concerns as officials struggle to achieve stable, long-term generation recovery.
