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.
Early power plants relied on water or fossil fuel to generate energy, and many of their basic principles remain in place today, albeit with larger, more complex, and more efficient capabilities. Power storage units, such as batteries and capacitors, have become ubiquitous in energy distribution processes, while electromechanical generators and nuclear power plants produce vast amounts of energy to meet the ever-growing need for electricity.
