Electrical energy generation involves the conversion of non-electrical power into a form of current that can be applied for industrial purposes. An electric charge is the product of subatomic interactions between particles, such as electrons. A charge will move across any material in which electrons can become excited, and if the necessary conditions are met, the charge will perpetuate itself into an electrical flow, or current. Electricity is typically generated by harnessing other forms of energy output, such as heat from fuel combustion or the kinetic motion of wind and water. Due to its versatility as a power source, electricity has a huge number of uses in the modern world, ranging from mass telecommunications and machinery operation to heating and lighting.
