Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, η (eta), ranges between 0 and 1. See more Energy conversion efficiency depends on the usefulness of the output. All or part of the heat produced from burning a fuel may become rejected waste heat if, for example, work is the desired output from a thermodynamic cycle. … See more In Europe the usable energy content of a fuel is typically calculated using the lower heating value (LHV) of that fuel, the definition of which assumes that the water vapor produced … See more • Cost of electricity by source • Energy efficiency (disambiguation) • EROEI • Exergy efficiency • Figure of merit See more The change of Gibbs energy of a defined chemical transformation at a particular temperature is the minimum theoretical quantity of energy … See more In optical systems such as lighting and lasers, the energy conversion efficiency is often referred to as wall-plug efficiency.
