3. Conventional electric
power plants
They produce most of the energy that we use.
Types:
● Nuclear power plants.
● Fossil fuel thermal power plants.
● Hydroelectric power plants.

4. Nuclear power plants
●They break down the fuel and it produces large
amounts of heat this heat is used to produce a
high pressure stream that moves the
turbines, this turbines are connected to a
generator that produces electricity.
● Main fuel: Uranium.
● Advantages:high return on their energy
production.

5. Fossil fuel thermal power

9. Non-conventional electric
power plants
● Advantages:They contaminate less than
conventional power plants,they use
renewable sources and reduce the energy
dependence.
● Disadvantages:they generate much less
energy

10. Types of non-conventional
electric power plants
● Wind power plants and wind farms
● Solar power pants
● Geothermal power plants
● Biomass Thermal power plants
● Ocean power plants

11. Wind power plants and wind
farms
● They use the movement of the wind,to move
blades which generate electricity thanks to a
transformation center at the bottom of the
tower where the blades are.
● Wind farms can only be installed in places with
good wind conditions
● A wind power plant produces between 1MW
and 10MW

12. Solar power plants
● They use the energy from the sun to produce
electricity
● Photovoltaic power
● Photo-thermal power plants

generator.

13. Geothermal power plants.
● They use the heats
found at the deep of the
Earth to produce
energy.
● These energy cn be
used:
● Directly:hot
water,heating and
industrial uses.
● Indirectly:the heat
generates stream which
produce electricity

14. Biomass thermal power
plants.
● Energy is produced
by burning organic
wastes,the steam
from the burning
moves a turbine
conected to a
generator.

15. Ocean power plants.
● These power plants
use the force of
waves and tides to
produce energy.
● They are in a
experimental fase so
they don't produce
too much energy.

18. From wind to water
 Eole water,the French research companyhas created a new
air rotor which can convert the whater steam in the air into
drinking water.
 The air enters into the turbine and goes into an electric
cooling compressor which condense the water in the air.
 One turbine can produce up to
1,000 liters of water every day
