1
Fission of nuclear fuel produces heat.
2
The burning of these fuels or the sun's rays produce heat.
The heat generated is used to produce steam under pressure
The steam under pressure moves the turbine
3
The turbine blades or wind turbine propellers move the air or water.
Turbine connected to a generator
Turning the turbine moves the generator
4
The energy contained in the photons of sunlight is converted directly into electricity.

Did you know..?
The electricity distribution network in Spain has a length of more than 600,000km, 15 times the perimeter from the earth.
The electric transport network consists of:
HIGH-VOLTAGE LINES
Transport large amounts of energy over long distances.
MEDIUM VOLTAGE LINES
Transport energy to medium-sized industries.
LOW VOLTAGE LINES
Bring energy to the point of domestic and residential consumption.
