The document discusses different types of power plants including coal fired power stations, brown coal power stations, hydroelectric power plants, and windfarms. Coal fired and brown coal power stations generate thermal energy from fuel combustion in steam boilers which is then converted to mechanical energy to power generators. Hydroelectric power plants convert the potential energy of water into electricity using industrial plants. Windfarms produce electricity using wind turbine generators, providing a clean energy source without fuel combustion.

3. Coal fired power station
Thermal energy typically comes from the combustion of fuel in a steam
boiler
The turbine follows the steam conversion of thermal energy into mechanical
energy drained shaft to an electrical generator

4. Brown coal power station
Thermal energy typically comes from the combustion of fuel in a steam
boiler
The turbine follows the steam conversion of thermal energy into mechanical
energy drained shaft to an electrical generator
In Belchatow is the largest Brown coal power station in Poland.

7. Hydroelectric power plants
Hydroelectric power is the most extensively used source of renewable
energy. Industrial plant converts the potential energy of water into
electricity
Hydropower plants are relatively cheap source of energy and can quickly
change the power generated depending on demand
In Poland in 2013, hydropower accounted for 1.5% of electricity production

11. Windfarms
The power plant produces electricity using generators (wind turbines) wind-
powered
Electricity derived from wind energy is considered to be ecologically clean
production of energy does not involve combustion of any fuel
The principle of operation of the power plant is simple and consists in the
fact that the windmill blades are driven by wind thereby producing electricity
in a turbine fan.
