The differences are HUGE!
Fossil fuels such as coal, oil and natural gas produce electricity usually by boiling water into steam. The steam is used to turn the electricity turbines to generate power.
The amount of pollution is collosal! Carbon dioxide, water vapor (both adding to the greenhouse layer), nitrous oxides and sulfur oxides (contributing to air pollution and acid rain), and in the case of coal power stations, fly ash and Mercury as well as the waste ash after burning.
Hydro-electric power stations use the energy of moving water and gravity to turn turbines to produce electricity. There is no carbon dioxide or any kind of pollution given off, so the energy is "clean and green".
(The building of the dams for hydro-electricity often damages the environment, the river banks and countryside, and sometimes cause earthquakes. There is also a certain amount of carbon dioxide and other pollution and waste produced in the manufacture of the turbines and the concrete and building of the dam.)
Hydroelectric power is about 90% efficient while fossil fuels are about 60% efficient.
they arn't the same type of energy
No it is its own source of energy
No, hydroelectricity is a Alternative energy resource.
whatever you want the advantages to be.
hydroelectric energy is free to the fuel fossil
Hydroelectric power is an alternative to production of electricity produced by fossil fuels
No, hydroelectric power is produced from the movement of water spinning a turbine. Fossil fuels (coal, oil and natural gas) produce energy by burning.
They both produce electricity, the first is clean and renewable, the second is not.
Fossil fuel is spelt correctly...
Coal is used in furnaces to heat water in a boiler to superheated (above 100 degrees Celsius) temperatures, and this steam is used to drive a turbine which, in turn, drives an alternator. A hydroelectric plant uses the vertical fall of water to drive a water turbine which drives an alternator.
Considerably safer and cheaper then decommissioning a fossil fuel, nuclear or hydroelectric powerplant relatively expensive
