Power Stations

An electric power station is a factory in which energy is converted from one form to electrical energy.

Types of Power Stations;

There are mainly three types of power stations:

• Thermal
• Hydro-electric
• Nuclear

Thermal Power Stations:

• In a conventional thermal power station, the thermal energy is generated from coal, gas or oil.

Hydro-Electric Power:

• Hydro-electric power stations are used where water resources are available in an ample quantity at sufficient head 
• Such plants are built along with the dam
• Low energy cost due to low operating cost

Nuclear Power Stations:

• The reserves of fossil fuel (coal, oil and gas) are gradually depleting, thus, there is a need to seek alternate sources of energy
• In a nuclear power station, like Karachi Nuclear Power Plant, instead of a furnace there is a nuclear reactor, in which heat is generated by splitting the atoms of the nuclear fuel, known as Uranium. 
• It reduces the demand for coal, oil and gas
