Energy is important because we need to use it everyday. Without energy we wouldn't have the sun, because that is solar energy. Without the sun, we would probably die. Our life would be so different without energy because we use electricity so, so much every day, and that's electric energy. We use energy at least 100,000,000 times a day, no doubt.
Energy can be found in so many different places, that it would take forever to list all the places. Though I can list a few places. Energy can be found in your house, in the sky, in a gym, and when you are playing at recess.
I think energy is whenever something, or someone moves in any way, like when you pull a rubber band back then let it go, or when you throw a basketball on the ground as hard as you can, then watch it soar into the sky. Those are all examples of energy, but there are thousands more. Energy is everywhere!
