The mechanical power needed to assist in this production is provided by a number of different sources. These sources are called prime movers, and include diesel, petrol and natural gas engines. Coal, oil, natural gas, biomass and nuclear energy are energy sources that are used to heat water to produce super-heated steam. Non-mechanical prime ...
Electricity is a very convenient way to transfer energy, and it has been adapted to a huge, and growing, number of uses. [75] The invention of a practical incandescent light bulb in the 1870s led to lighting becoming one of the first publicly available applications of electrical power.

Electric utilities measure energy using an electricity meter, which keeps a running total of the electric energy delivered to a customer. Electric heating is an example of converting electrical energy into another form of energy, heat. The simplest and most common type of electric heater uses electrical resistance to convert the energy. There ...
The vast majority of electricity used is created from centralised generation. Most centralised power generation comes from large power plants run by fossil fuels such as coal or natural gas, though nuclear or large hydroelectricity plants are also commonly used. [29] Centralised generation is fundamentally the opposite of distributed generation ...
Electric power is the rate of transfer of electrical energy within a circuit.Its SI unit is the watt, the general unit of power, defined as one joule per second.Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively.

Electricity can be used in many ways in which heat cannot. So the loss of energy incurred in thermal electricity plants is not comparable to a loss due to, say, resistance in power lines, because of quality differences. In fact, the loss in thermal plants is due to poor conversion of chemical energy of fuel to electricity by combustion.
