ENERGY AND ITS TRANFORMATION
ENERGY SOURCES
Energy sources are natural resources from which we obtain different forms of energy that can be transformed for a specific use.
The energy we consume has many different uses
Industrial uses
Household use
We can classify energy sources in several ways
By availability in nature and capacity for regeneration
Renewable
Non-renewable
By origin
Primary
Secondary
By use in each country
Conventional
Non-conventional
By environmental impact
Clean or non-polluting
Pollutants
ELECTRICITY
Electricity is the most widely used form of energy industralised societies for two reasons
It can be easily transformed
It can be transported long distance
ELECTRIC POWER PLANTS
Electric power plants are facilities where primary or secondary energy is transformed into electricity,
The turbine converts mechanical energy into the rotating movement of a shaft
An alternator has a fixed part, called a stator, and a moving part, called a rotor, connected to the turbine shaft
TRANSPORT AND DISTRIBUTION OF ELECTRICAL ENERGY
Electric power plants are usually located far away from the points where the energy is used — fur safety reasons, space requirements or physical and geographical considerations.
CONVENCIONAL ELECTRIC POWER PLANTS
NUCLEAR POWER PLANTS
This type of plant includes a nuclear fission reactor that produces the
pressunsed steam needed to move the turbine rotor. Uranium is the main fuel used.
FOSSIL FUEL THERMAL POWER PLANTS
At this type of power plant, water is heated in a boiler by the heat
generated from the combustion of a fossil fuel, usually natural gas or coal. The steam that's generated moves the turbine connected to the generator.
Combined cycle power plant
Electricity is generated as a result of two combined cycles, a cycle that uses air and gas, and a conventional thermal cycle
HYDROELECTRIC POWER PLANTS
This type of power plant uses the potential energy provided by the height of the stored water in a dam, converting it into kinetic energy. This energy moves the blades of the turbine
Gravity-driven hydraulic power plants
Pump-dniven hydraulic power plants
NON-CONVENTIONAL ELECTRIC POWER PLANTS
The environmental problems caused by conventional power plants have led to the creation and development of non-conventional or alternative energy power plants
WIND POWER PLANTS AND WIND FARMS
SOLAR POWER PLANTS
Photo-thermal power plant
Photovoltaic power plant
GEOTHERMAL POWER PLANTS
BIOTHERMAL POWER PLANTS
OCEAN POWER PLANTS
