The Children's Palace tells a story about what is what, which illustrates a problem.

On Friday, my mother took me to the Children's Palace. I am very excited because I haven't been to the Children's Palace for a long time. (Tell me one thing)?

When we arrived at the Children's Palace, we first visited the energy world. It is said in the introduction that the ancients first used lightning to make fire, but they were also very clever. They found that friction can also make a fire. Sometimes we use friction to make a fire, which was handed down by the ancients. We now have a lot of power generation, such as wind power, dust removal, drinking fork barrels and singing oil and water. (through this matter)?

The method of wind power generation is to install windmills on the hillside. When the wind blows over the windmill and rotates, it can generate electricity. The way to generate electricity with oil is to put oil into the generator. ?

Using water to generate electricity is to use the reservoir to open the gate and release water to drive the generator to rotate. After the generator rotates, it can generate electricity. But there are not many power generation resources on the earth, and the future power supply will come from the resources on the moon. If human beings are still dispersing the resources of the moon, they will have no resources to generate electricity. (explain the problem)
