Does everything on earth create energy?

    Technically, no.  According to the first law of thermodynamics, Energy can never be created or destroyed — it just “is”.  In many cases, we can take the energy of something and convert it into usable energy like electricity.  A good example of energy conversion is a catapult.  A heavy weight is lifted on one end of a fulcrum, giving it “potential” energy, while the other end of the fulcrum is loaded with a projectile.  When the weight is dropped, its energy is converted from potential to “kinetic” energy, causing the projectile to be hurled through the air.

    On the other hand, Einstein’s famous equation, E = mc^2, states that everything that has mass (e.g. nearly everything on Earth), also contains energy.  Energy is inherent in mass!
