Electricity energy
Energy consumption, energy resources and the place of electricity

Electricity was first generated mainly by hydroelectric power, before thermal power plants gradually came to dominate to meet rapidly growing needs. Whether they run on fossil fuels (coal, oil, natural gas), nuclear fission or biomass or household waste, these power plants use a steam or combustion turbine (except for low-power diesel internal combustion engines), driving an alternator. This thermomechanical conversion method has an efficiency ranging from 30% to 60%...
