Windmills are like big fans, but instead of using electricity to make wind, they use wind to make electricity! This is called wind energy. Have you seen big shiny plates on rooftops? Those are solar panels. They soak up the sun’s light and turn it into electricity. This is called solar energy. Ever seen a big dam on a river? It's not just for controlling water, but also for making electricity from the moving water. This is called water energy. These are all clean energies because they don't make pollution. Isn't it cool how nature helps power our lives?
