From Racecars To Lightbulbs: Where does energy come from?

We can get energy from many things Oil

Why is energy important? Hello! I am energy! I am all around, all the time even though you can’t see me. Everything has energy in it. It’s what makes things move faster, or feel really hot, or shine brightly. Here, let me show you.

First, let me show you what happens when I add energy to this bouncy ball. You see, the energy is causing the ball to bounce. Don’t worry, energy cannot be destroyed. It can only be changed from one form to another. By hitting the other ball, I changed from bouncing energy to rolling. Now, let me show you what else I can do.

Here is one last trick. I’m still here. I moved from the rolling ball to this windmill, and caused it to start spinning. Spinning the windmill changed me into electrical energy, so now I am able to power this light bulb and create light.
