Electric steam boiler on the training ship Golden Bear. An electric steam boiler is a type of boiler where the steam is generated using electricity, rather than through the combustion of a fuel source. Such boilers are used to generate steam for process purposes in many locations, for example laundries, food processing factories and hospitals ...
L.D. Porta gives the following equation determining the efficiency of a steam locomotive, applicable to steam engines of all kinds: power (kW) = steam Production (kg h −1)/Specific steam consumption (kg/kW h). A greater quantity of steam can be generated from a given quantity of water by superheating it.
Map of all utility-scale power plants. This article lists the largest electricity generating stations in the United States in terms of installed electrical capacity. Non-renewable power stations are those that run on coal, fuel oils, nuclear, natural gas, oil shale, and peat, while renewable power stations run on fuel sources such as biomass, geothermal heat, hydro, solar energy, solar heat ...
The cycle 1-2-3-4-1 which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking place in the high temperature region. The cycle a-b-c-d-e-f-a which is the Rankine steam cycle takes place at a lower temperature and is known as the bottoming cycle.
Worldwide, most electric power is produced by steam–electric power plants. [1] The only widely used alternatives are photovoltaics , direct mechanical power conversion as found in hydroelectric and wind turbine power as well as some more exotic applications like tidal power or wave power and finally some forms of geothermal power plants.

A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.

Coal generated 16% of electricity in the United States in 2023, [1] an amount less than that from renewable energy or nuclear power, [2] [3] and about half of that generated by natural gas plants. Coal was 17% of generating capacity. [4] Between 2010 and May 2019, 290 coal power plants, representing 40% of the U.S. coal generating capacity, closed.
