Scientists define energy as the ability to get work done. You could be breathing, giving a party, building a pyramid, or even taking a nap. But where is energy?

Energy is in wind, waves, and sunlight, as well as in streams and rivers. There is definitely energy in you. And it’s in every other living thing, whether animal or vegetable.
