Imagine our planet is a big, beautiful house where we all live, including animals and plants. We need energy to keep our house bright, and warm, and to use things like refrigerators and to play video games.
Energy from coal and oil makes the air and water dirty. This makes our house messy and too warm!
Energy from wind turbines is just about endless and free! Using clean energy is our way of keeping our big house clean, safe, and wonderful for everyone.
