What is Energy?

In the simplest terms, energy is the ability to do work. Energy is also represented in terms of any source of usable power. In different ways, energy is used to do almost everything such as jumping, walking and the operation of machinery. For instance, the foods human consume contain energy which is stored in the body and converted into energy every time we engage in any duty or work such as sports. The stored energy is termed as potential energy while the working energy is termed as kinetic energy.

The electricity used in our homes is also a form of energy because it is a form of usable power. The places from which the different energies are obtained are known as energy sources. Examples include burning coal, nuclear reactions, petroleum, and so on. Energy sources are divided into two major categories namely renewable energy and non-renewable energy.

Renewable energy is from sources that can be replenished easily while non-renewable energy cannot be easily replenished. Example of renewable energy is wind energy while fossil fuel is an example of non-renewable energy. In physics, energy is explained as the thermodynamic quantity equivalent to the capacity of a physical system to do work. The units of energy are ergs or joules.
