Energy gives you the power to live out your dreams. Energy comes in many different forms - heat (thermal), light (radiant), mechanical, electrical, chemical and nuclear.
We use energy to do everything we do, from making a house to baking our favourite cookies to sending astronauts into space. Energy is there, making sure we have the power to do it all. There are two types of energy - stored (potential) energy and working (kinetic) energy. For example, the food you eat contains chemical energy and your body stores this ENERGY until you release it when you work or play
