Cuba has a big problem. The country has no lights. Ten million people have no power. This is a big problem.
The problem is no fuel. People are not happy. The power went out Monday.
Cuba needs oil for power. But Cuba has no oil. The leaders say no oil came. Venezuela sent oil before. Now Venezuela has less oil.
Old power places need oil. They are very old. Venezuela is Cuba's friend. They send oil to Cuba.
But Venezuela has problems. They have less oil. Some oil came. But it was not enough. Cuba wants more oil.
Other countries make problems. They stop oil for Cuba. This makes the fuel problem bad.
Life is hard with no power. Many things do not work. People are upset. They are not happy.
Fixes are happening. But big problems stay. Cuba will have hard times. This shows Cuba's problems.
