The document discusses different types of electric power plants including conventional power plants like nuclear, fossil fuel, and hydroelectric plants as well as non-conventional plants such as wind, solar, and geothermal. It describes how each type of plant works and generates electricity and also addresses the environmental impacts of electric power generation including resource depletion, pollution from transportation and operations, and effects of infrastructure development.

3. ELECTRICITY
Electricity is the most widely used form of energy in
industrialised societies for two reasons:
-It can be easily transformed into other forms of
energy(light,heat...)
-It can be transported long distances inexpensively
and with very little energy lost

9. NON CONVENTIONAL
ELECTRIC P.PLANTS
- Wind power plants and wind farms
-Solar power plants
-Geothermal power plants
-Biomass thermal power plants
-Ocean power plants

10. WIND POWER
They use the kinetic energy
of the wind to move the PLANTS
blades of the wind turbine
There are also “Wind farms”
wich are a clean form of
generating electricity

11. Th e r e a r e tw o typ e s : SOLAR POWER
PLANTS
Photo-thermal power plants,it Photovoltaic power
uses the heat generated by plants,uses
solar radiation to produce photovoltaic cells to
steam and move a rotor in transform solar
the generator radiation into electricity.
To do this special mirrors are
used,called heliostats

12. GEOTHERMAL
These plants use the heat found
POWER PLANTS
at deep levels in the earth.
This heat may reach the
surface in the form of steam,
gases or hot water
This energy may be used
directly or indirectly.

13. BIOMASS THERMAL
POWER PLANTS
Biomass is subjected to different physical and chemical processes in
order to produce fuel such as charcoal,alcohol or biogas
This type of fuel is burnt at biomass power plants.They come from:
Forestry and agricultural waste
Specific crops,such as sunflowers and sugar beet
Waste from agri-food industries

14. OCEAN POWER
PLANTS
These power plants use the energy from the seas and the oceans.
Use three types of energy from the sea:
-The mechanical energy from the tides
-The mechanical energy from the waves
-The energy from the ocean's thermal gradient
These power plants are still in the experimental phase and their level
of production is still very low.

15. ENVIRONMENTAL
IMPACT
E n v ir o n m e n t a l im p a c t a s s e s m e n t
An electrical power plant produces an ecolological change because
it produces waste and needs an infrastructure.
To avoid that is necessary to do an environmental impact assesment
and an environmental study to show all the consequences

17. Do you think wind turbine can
produce fresh water?
We think that 1000 liters of
water are a very small
amount of water to everyody,
but it is a good idea that we
can develop with better
technology
We think that in a near future
this idea can be developed
with better results
