“The blackout is the culmination of decades of disinvestment, an economic crisis, and global factors affecting the country’s oil supply, and there doesn’t seem to be a long-term solution to the crisis.
The Cuban government regularly imposes hours-long blackouts in different parts of the country to conserve the fuel necessary to run the electrical plants. But the current outage is different. It was sparked by a breakdown at one of the country’s aging electrical stations and has affected every facet of life for ordinary people: They cannot cool or light their homes, food is spoiling in refrigerators, they cannot cook, and many can’t access water to drink or wash.
Though the situation has now reached a crisis point, it’s a tragedy that has developed over time and emphasizes Cuba’s fragile economy, development imperatives, and its tenuous place in world politics.”
