Electricity is the flow of electrical power or charge. It is a secondary energy source. We get it from the conversion of other sources of energy like coal, natural gas, oil, nuclear power and other primary sources.
The methods to generate electricity are as follows:
- Electricity through fossil fuels: Electricity can be produced by burning fossil fuels. Fossil fuels can be petroleum, coal and natural gas. Fossil fuels are used to make fire and boil water. When the water is heated enough, its vapor are used to move turbines and make electricity.
- Electricity through water: This is also known as hydropower. It is a process in which a running water is used to spin turbines connected to a generator thus making electricity.
- Electricity through wind: This is also known as wind power. It is a process in which wind is used to move turbines and make electricity.
- Electricity through nuclear: This is also known as nuclear power. It is a method in which steam is produced by heating water through a process called nuclear fission. This steam spins a turbine generating electricity.
- Electricity through sun: This is known as solar power .Solar-thermal electric generators use the radiant energy from the sun to produce steam to drive turbines, thus producing electricity.
- Electricity through biomass: Biomass includes wood, municipal solid waste (garbage), and agricultural waste, such as corn cobs and wheat straw. These sources replace fossil fuels in the boiler. The combustion of wood and waste creates steam that is typically used in conventional steam-electric plants.
