5.ELECTRIC POWER STATIONS THAT USE NON-RENEWABLE ENERGY SOURCES:
There are two types:Thermal power station and nuclear power stations.

5.1.THERMAL POWER STATIONS THAT FOSSIL FUELS:

• Produce thermal energy.

• Fossil fuels,such as coal,oil  and natural gas,are used to heat wáter in a boiler.

COMBINED-CYCLE POWER STATION:
The first system burns natural gas with compresses air.This produce superheated gases,which turn a turbine to generate electricity.The second system uses the hot gases from the first system and uses them to produce steam in a heat recovery boiler.

5.2.NUCLEAR POWER STATION:
The reactor radioactive material as fuel.The most commonly used materials are isotopes of uranium.

Advantages:Of nuclear power stations are their productivity and profitability.They produce lots of electricity that can be sold at a profit.

Disadvantages:Of nuclear power stations are the risks of nuclear accidents an the management and storage of radioactive waste.
