Cuba's lights went out. The whole country has no power. This happened three times. People are sad.
The lights went out Sunday. No power for anyone. Some lights came back. But many people have no lights. Hospitals get power first. This is hard for many people.
Cuba needs oil. It does not have much oil. The US stops some oil. This makes it hard to get oil.
People are not happy. They make noise. Some people go to the leaders. The power problem is bad for money.
Help is coming. Some help is on the way. Bad weather stops some help. Cuba has problems now.
