What Is Energy?

Energy is the ability to do work, as baking a cake in the oven to moving cars along the road. Energy can appear in one form or another, in other words, it is transferrable and can be converted from one form to another. There are different forms of energy, including kinetic, heat, potential, chemical etc. All forms of life including human, extract energy from the environment and convert it to forms which can be used e.g. from wood to heat and from fossil fuels to electricity.
