On the island of Cuba, power is gone. The entire Strom-Netz fails completely. This happens a second time now. About 10 million people suffer. Many houses stay dark. Internet and phones fail too.
The tech in Kuba is old. The power plants break down. Oil for power is missing. Kuba gets no fuel from other nations. The government blames the USA. The USA has strict rules for trade.
The USA says something else. The government in Kuba plans badly. That causes the tech to break. In July, 3 big outages happen. The embassy warns travelers now. Power returns to only few parts of Havanna.
