Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry , it is the stage prior to its delivery ( transmission , distribution , etc.) to end users or its storage , using for example, the pumped-storage method.

A plan to replace coal, oil, or natural gas fuel with other sources to produce electrical energy. fossil-fuel power station A power plant using coal, oil, or natural gas fuel. Fourier series A set of coefficients of sine and cosine waves; this can represent a time function as a function of frequency. Fourier transform
The thermodynamic cycle used by most boiler–turbine generating units. This cycle includes addition of heat in the boiler, extraction of energy through expansion of steam in the turbine, and rejection of heat using the condenser and cooling tower. Brayton cycle: Reaction turbine
Another machine used for converting mechanical energy into electrical energy by means of electromagnetic induction is called a dynamo or direct current generator. The key difference between an alternator and a generator is that the alternator delivers AC (alternating current) to the external circuit, while the generator delivers DC (direct ...
A certain amount of generation must always be held in reserve to cushion an electrical grid against inevitable disturbances and losses. [73] With increasing levels of variable renewable energy (wind and solar energy) in the grid, it has become more challenging to match supply and demand. Storage plays an increasing role in bridging that gap.
The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal , oil , and natural gas to generate electricity. Cleaner sources include nuclear power , and increasingly use renewables such as the sun , wind , waves and running water .
Water is pumped uphill into reservoirs during periods of low demand to be released for generation when demand is high or system generation is low. [22] Other forms of electricity generation with hydropower include tidal stream generators using energy from tidal power generated from oceans, rivers, and human-made canal systems to generating ...
