By origin
By use in each country
By availability in nature and capacity for
regeneration
By environmental impact
Electricity
. Electric power plants
How an electric power plant works
alternator
turbine
. Transport and distribution of electrical energy I
Transporting it by high voltage cable attached to towers
Decreasing the voltage at the electncity substations to 3-30 kV
Increasing the voltage to 220 000 V or 400 000 V to prevent significant energy loss, due to the Joule effect
Distnbution to homes, offices, industnes and public faolities Dunngthis srage, the voltage is reduced to 230-400 V.
Conventional electric power plant
Fossil fuel thermal power plants
Combined cycle power plan
Hydroelectric power plants
Gravity-driven hydraulic power plants
water used follows the course of a river and will not be reused
Pump-dniven hydraulic power plants
water descends into a reservoir located at a lower height, then pumped to a higher reservoir to reuse it
Nuclear power plants
nuclear fission reactor
Non-conventional electric power plants
Geothermal power plants
