Background

Energy is a physical quantity that describes the amount of work that can be performed by a force to produce heat or light or movement.  We need energy for everything we do; energy is, and will continue to be, a primary engine for human and economic development.
One of the laws of the universe is that matter and energy cannot be created nor destroyed.  But energy can be changed in form. It is a concept created by humans to quantify interactions between very different physical phenomena. These exchanges are controlled by the laws and principles of thermodynamics. The unit for measuring it is the Joule.
