Hello, we are Manuel Alejo and Alicia Llera from 3ºA, here is our project of electric power plants

energy sources.

4. Nuclear Power Plants
They produce heat by fission of uranium atoms,
some of them use plutonium.To produce
electricity, a power plant needs a source of heat to
boil water which becomes steam. The steam then
turns a turbine which turns an electrical generator
to produce electricity. The most important part is
the nuclear reactor.

5. Fossil Fuel Thermal Power Plants
First, water is heated in a boiler by the heat generated from
the combustion of fossil fuels. Next, the steam that was
generated, moves the turbine connected to the generator.
Combine cycle power plant: The steam that was generated
is recycle (instead of relaised it to the atmosphere) and
use to produce electricity again.

6. Hydroelectric Power Plant
It uses the force of water to produce electricity.
First, reservoirs collect rainwater, when the
water flows throught the turbines they porduce
electricity.

The wind turns the blades, which spin a shaft,
which connects to a generator and makes
electricity

in the generator.
They use especial
mirrors (heliostats).

10. Geothermal Power Plant
The plants use the heat founded at deep levels in
the earth. This heat may rich the surface in the
form of steel gases of hot water.
It can be used:
1. Directly (hot water and heating indistrial uses
and so on).
2. Indirectly; it generates steel which produce
electricity

11. Biomass Thermal Power Plants
Urban and agricultural organic waste is burned.
The heat and gases produced by decomposing
waste are then used to move turbine echich
generate electricity.

12. Ocean Power Plant
They use the waves, the tides and the differences of temperature in the water to
produce energy:
Waves: Energy is form of the kinetic energy that exists in the moving waves. First, the
wave raises into a chamber, then the water forces the air out of the chamber,
moving air spins a turbine which then turns a generator.
Tides:When tides comes into the shore, they can be trapped in reservoirs behind
dams. Then when the tide drops, the water behind the dam can be let out just like in
a regular hydroelectric power plant.
Difference of temperature:
1. Warm surface water is hot enough to boil a fluid with a low boiling point.
2. The gas from the boiling fluid creates enough pressure to drive a turbine that
generates electricity.
3. The gas is then cooled by passing it through cold water pumped up from the
ocean depths.
4. The gas condenses back into a liquid that can be used again.
5. The water is returned to the deep ocean.

14. Wind turbine creates water
It´s a beneficial project which we can give it a great support,
also, it would be a solution for the zones with problems of
abstinence of water. What the WMS1000 does is to
transform the air humidity into drinking water, and to this
great idea, we add one more thing, we don`t need
traditional or electric energy for this transformation
because it does through a wind turbine. So, it is right
because it does not damage the environment. Many
people would benefit from this project because they do not
have direct access to water and have to travel miles just to
have much water to drink. The problem is that it is very
expensive, but the effort of all countries will be great,
although they do not benefit directly from them
