1. Energy
By Jose Miguel Herrera and Jorge Salguero

2. What Is Energy?
Energy is the capacity
that an object or body
has to transform a source of
energy into work.
The energy is measoured in
Joules, (J) and KiloJoules
(kJ). Heat is also measured in
Calories,(cal) as Joules,
calories have a larger Unit,
KiloCalories, or Kcal.

3. Types of Energy
Kinetic Energy: The energy that Objects have
when they move.
Potential energy: The energy that objects
have when their equilibrium Point is moved.

4. Types of Energy (II)
Electrical Energy: It's the energy Of an
Electric Current
Electromagnetic Energy: The energy of
electromagnetic waves

5. Types Of Energy (III)
Sound Energy: The sound waves which are
transmitted through vibrations
Chemical Energy: the energy asociated with
Substances or atoms.

6. Types Of Energy (IV)
Nuclear energy: It's contained in the nuclei of
atoms.
It's the vibration of particles in matter.

7. Energy Sources
Energy Sources Is The Resource where we
get the different types of energy. There are
renewable and non-renewable. Both will be
explained in the following slides.

8. Non-Renewable Energy Sources
They are types of energy which will end,
sooner or later. They were formed Many
years ago, they are found deep
underground and need special machinery to
be extracted. They are explained In the next
Slides.

9. Nuclear Energy
It is stored in the nuclei of atoms
It is released by making the atoms crash each
other by:
Nuclear Fussion: 2 light nuclei for a bigger
nucleus
Nuclear Fission: One Big nucleus is split into 2

10. Coal
It was formed 300 Million years Ago, by the
remains of plants and animals. It's extracted
in 2 ways:
Open-Cast Mines: When the coal is found near the
surface
Underground Mines: When the coal is found deep
underground.

11. Petroleum
It was formed by the transformation of the
organic remains of the earth, by the
bacteria. It has lower density than water
has.
It is extracted by oil rigs, they use wells to
find the petroleum and by pumps or natural
force it gets pushed up to the surface. Then
it gets purified, after that, an oil tanker
carries it to it's destination by sea.

12. Natural Gas
It's a mixture of gases formed by the
decomposition of plants and animals. It's
found in underground gas fields, usually
you find petroleum near it.
It's extracted by drilling.
It's transported by transforming it into liquid
and moving it through gas pipelines. It's
destination is a Liquefaction plant.

13. Renewable energy Sources
Now We Will explain several types of
renewable energy sources. A renewable
energy source is a source which energy won't
run out, there are unlimited Resources for it.

14. Hydraulic
The hydraulic energy is the type of Source
that produces energy from the water. It can be
found in Hydroelectric dams. This energy is
cheap, clean and it is not polluted, but
building the dams is very expensive, and in
case of breakage, there is a huge risk of
catastrophe.

15. Solar
The solar energy is the source of energy that
uses the Sunlight to produce it. The Machine
that helps us obtain & Transform the solar
energy Are the solar panels. This energy is
clean and unlimited, but it's quite expensive.

16. Wind
This energy has been always used for moving
things, such as ships, Blades...
The machine we use to produce this energy
are Wind Turbines. This type of energy is Very
Cheap, And unlimited.

17. M a r in e
Th e r e a r e 3 typ e s :
Tid a l: E x t r a c t e d F r o m t h e Tid e s
W a v e : O b t a in e d f r o m t h e w a v e s
O c e a n t h e r m a l: G o t t e n f r o m t h e
d if f e r e n c e o f t e m p e r a t u r e o f
the s u rfa c e a nd b o tto m o f the
sea.

18. Geothermal
This energy comes from the heat stored below
the earth, such as geysers and volcanos.
Depending on the temperature, we can
produce heat or electricity

19. Biomass
It is produced from organic matter waste and
and plant remains. It is used in 2 ways: To
produce electricity and to produce fuels, these
are: charcoal, biogas, biodiesel and alcohol.

20. Municipal Solid Waste (M.S.W)
This is the waste that we produce in our
homes, demolition of buildings, etc. This is is
what goes to the Landfield. Electrical and
Thermal energy is produced through the
incineration of these wastes.

21. Types of power Stations
In the following slides we will explain the
types of power Stations that operate allover
the world these days. A Power station is
usually a building which it's only objective is
to produce energy.

22. Nuclear power plant
A nuclear power plant is the place where the
nuclear energy is extracted. In it, the heat
source is One or more chemical reactors. The
heat produced by them is them moved to a
Boiler which rotates a generator to produce
electric current.

23. It works as follows:

24. Oil rig
An oil rig is the place where oil gets extracted.
It is usually in the sea. It works with a drill
which is mined deep underground, near the
oil. When it reaches the oil, the drill is pulled
up and the oil rises by pressure, or by action
of pumps

25. How does it work?

26. Natural gas Power Plant
It is extracted the same way as petroleum, in
fact, when you look for petroleum, you usually
find natural gas over it. A drill is mined
underground until it reaches natural gas, then
by pressure or the force of a pump, The gas
pulls up.

27. How does it work?

28. Hydraulic power plant
An hydraulic power plant is usually placed in
rivers, it's a big wall by which water passes
throught conducts and moves a generator to
produce electricity.

29. How does it work?

30. Solar power plant
A solar power plant is the place where solar
panels are grouped to produce energy. They
have photovoltaic cells which catch the sun
energy and transform it into heat or electricity.

31. How big is it?

32. Eolic power plant
An eolic power plant is a group of wind
turbines which produce energy from the wind.
They Are usually on Windy places like Valleys.
The wind moves the blades of the turbine
which rotate a generator.

33. How does it work?

34. Coal Mine.
A coal mine is the place where coal is
extracted. As explained before, it can be
buried underground or at the surface of the
earth. Special machinery is used to extract
this material.

35. How Does it work?

36. Geothermal Power station
This is the place where the heat from earth's
crust is stored and transformed into
electricity, or kept in heat form.

37. How does it work?

38. Municipal Solid Waste Plant
This is the place where our Daily Trash is
incinerated to produce electrical or either
thermal energy. The incineration temperatures
should always be over 900ºC and Filters would
be used to prevent the release of toxic
substances to the atmopsphere.

39. This is How it works:

40. Wind Turbine creates Water From
Thin Air – Our Oppinion.
When we first readed it, it looked like
something by which you think: How Come this
can be done? But as we scrolled down we
noticed that the procedure is actually quite
easy. Just pick air, extract the humidity, cool it
down and you got water. Simple as that.

41. Would this help underdeveloped countries?
We think it will. Just get someone nice to
donate the 500k€ it costs and You got water
for like 3-4 african villages. We think that if
you made a NGO (Non-Gubernamental
organisation) you could quickly get some of
these installed in africa. For like 20€ per family
and month, 500 members, you get 10000€ per
month, you can get the money for one in like
2.5 years. Easy. The thing that really
impressed us is that it can produce 1000l of
water a day. One THOUSAND litres of water?
that's a lot. Overall, amazing idea. We liked it a
lot
