EVERYDAY SCIENCE

Detailed explanation-1: -Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.

Detailed explanation-2: -Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity.

Detailed explanation-3: -To produce electricity, a turbine generator set converts mechanical energy to electrical energy. In the cases of natural gas, coal, nuclear fission, biomass, petroleum, geothermal and solar thermal, the heat that is produced is used to create steam, which moves the blades of the turbine.

Detailed explanation-4: -Nuclear energy is produced from uranium, a nonrenewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity.

Detailed explanation-5: -Fossil fuel power plants burn coal or oil to create heat which is in turn used to generate steam to drive turbines which generate electricity.
