Electricity net generation
Generation data consist of both utility and non-utility sources from electricity and combined heat and power plants. Data are reported as net generation, not gross generation. The difference between gross and net generation is generally about 6% for fossil fuels stations, 1% for hydro stations, and 5% for all others. Fossil Fuels electricity generation consists of electricity generated from coal, petroleum, and natural gas. Solar electricity generation includes solar photovoltaic and solar thermal generation, and distributed solar generation where available. The term biomass and waste used here is similar to the term combustible renewables and waste. Electricity net generation excludes the energy consumed by the generating units and generation from hydroelectric pumped storage. Generation from hydroelectric pumped storage plants is included in total generation.
