ELECTRIC POWER STATIONS THAT USE NON-RENEWABLE ENERGY SOURCES

- Thermal power stations.
Produce thermal energy.

Fossil fuels are used to heat water in a boiler, then the boiler turns a turbine, which is connected to the rotor of a generator and produces electricity and it is transported. After that the steam goes to a condenser and becomes liquid water again. Finally, the water is pumped back to the boiler.

In combined-cycle the electricity is genertaed in two systems.
· First system: burns natural gas with compressed air and this produce superheated gases.
· Second system: use the hot gases from the first system.

- Nuclear power stations.
Is a thermal power station that uses a nuclear reactor to produce heat. The reactor uses radioactive material such as uranium.
· Advantages: productivity and profitability.
· Disadvantages: the risks of nuclear accidents and the management and storage of radioactive waste.
