Finite resource
Large amount of pollution
Blown into the furnace
Water is turned into steam by the heat because is pumped through pipes inside the furnace
Steam is the piped to the turbine
Pressure of the steam against the turbine blades turns the turbine shaft
Turbine shaft is connected to the shaft of the generator
Where magnets spin within coils to produce electricity
Driving their turbines in the same mode as a coal fired plant
Clean
Efficient
Dangerous
Pressurized water reactor
Water is heated and circulated around the pipes inside the steam generator, in order to create steam
Boiling water reactor
Water heated by fission actually boils and turns into steam
Which in turn are coupled to synchronous generators and hence produce electricity
Waste free
Expensive
Impact
Ethanol
Produced by means of the fermentation of materials which contain sugar
Corn
Biodiesel
Produced by a transesterification where glycerine is separated from fat or vegetable oil adding ethanol or methanol
