ELECTRICITY
Electricity is the most widely used form of energy in industrialised societies.
In can be easily transformed
It can be transported long distances
Electric power plants
Facilities where primary or secondary energy is transformed into energy
Turbine-alternator systems
Turbine
Converts mechanical energy into the rotating movement of a shaft
Altenator
Fixed part
Stator
Moving part
Rotor, connected to the turbine shaft
As the rotor shaft moves, alternating electrical current is produced on each of the stator's coils
Conventional
Nuclear
Nuclear fission reactor
Fossil fuel
Water heated in a boiler
Hydroelectric
Water in a dam
Non- conventional
Wind
Wind turbine
Solar
Photo-thermal
Photovoltaic
Geothermal
Heat under the surface
Biomass
Organic compounds from natural processes
Ocean
Energy from seas and oceans
Cannot be stored
Environmental impact
Processes with an environmental impact
