ENERGY
1.Energy sources
Household uses
Industrial uses
(hydraulic, geothermal, nuclear, wind power, solar, petroleum and its derivatives, coal, natural gas, biomass, tidal power)
2.Electricity
It can be easily transformed
in other forms of energy .
It can be transported long distances
inexpensively and with very little energy bein lost.
Electric power plants
works:
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
different plants
electrical power station
high voltage network
distribution to industry
medium voltage network
electricity substation
distribution to industry and to homes
low voltage networks
3.Conventional electric power plants
Nuclear power plants
, this type of plant includes a nuclear fision reactor that produces the pressurised steam neded to move the turbine rotor.
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.
Hydroelectric power plants
, this type of power plants uses the potential energy provided by the height of the stored water in a dam, converting itinto knetic energy. This energy moves the blades of the turbine
4.Non-conventional electric power plants
Wind power plants and wind farms
, use kinetic energy of the wind to move the blades of a rotor at the top of a tower; wind turbine
Solar power plants
Photo-thermal power plants
Photovoltaic power plants
Geothermal power plants
,use the heat found at deep levels in the earth. This heat may reach the surface in the form of steam, gases or hot water.
Biomass thermal power plants
. consists of all organic compounds that are produced through natural process.
Ocean power plants
, these power plants use the energy from the seas and the oceans. The concept is to use three types of energy from the sea. (tides, waves, thermal gradient)
5.Enviroment impact
Environmental impact assement
study must also asses both the economic and social consequences of the project in the area, to decide whether or not go ahead with the plan.
Environmental impacts
Extraction of natural resources
Fuel transport
Electricity generation
Final energy use
Waste tratment
to reduce the waste generated by the thermal power plants, as well as their effects, several measures can be taken.
Some solutions
, effiency, energy diversification and energy savings.
