Okay kiddo, so a long time ago in the 1970s, people had big problems getting enough energy to power their homes and cars. They couldn't just go to the gas station or turn on the lights like we do now. There were a few reasons for this energy crisis.
First, in the Middle East, where a lot of the world's oil comes from, some countries were not happy with other countries and decided to stop selling their oil. This means that countries like the United States had to find other places to get their oil from, which was more expensive and took longer to get.
Second, the fuel that people could get was really expensive, so people had to wait in long lines at gas stations just to get a tiny bit of gas. Sometimes, they even had to wait for hours.
Third, people started realizing that we were using too much energy and causing harm to the environment. There were protests, and people started using less energy or looking into alternative ways to get energy, like solar power or wind power.
Overall, the 1970s energy crisis was a time when people had to think more carefully about how they used energy because it was harder and more expensive to get. But it also helped us realize that we need to find better ways to get energy that won't harm the world we live in.
