Energy is natural resources and things that we use to make things work. The environment is the world around us. Energy and the environment are connected because the things we use to get energy can have an effect on the environment. For example, burning fossil fuels like coal, oil, and natural gas makes a lot of pollution which can harm the environment. So if we want to help keep the environment healthy, we need to use energy more wisely and find better ways to get it that don't hurt the environment.
