Energy is the ability to do work and comes in many forms including light, thermal, kinetic, gravitational, chemical, nuclear, and sound. Different types of energy can be converted from one form to another according to the law of conservation of energy, but energy itself can neither be created nor destroyed. For example, falling water converts its potential energy into kinetic energy which can then be used to generate electricity.
