3. Types of energy
Mechanical energy
Electrical energy
Electromagnetic energy
Sound energy
Chemical energy
Nuclear energy
Thermal or calorific energy

4. Mechanical energy
Mechanical energy is energy that is produced by
the position and motion of a body, can be
potential and kinetic.
-Kinetic energy is produceed by the motion of an
object
-Potencial energy is produced when an object
move from its stable position of equilibrium.

5. Electrical energy
The electrical energy produced by the motion of
electrical charges through a lead wire.

6. Electromagnetic energy
Is the energy that is produced from
electromagnetic radiation.This energy is
transported by electromagnetic waves. One of
this is the luminous energy.

7. Sound energy
The sound energy is the energy that carry sound
waves. It comes from the vibrational energy of
sound focus and spreads to the medium particles
that cross in the form of kinetic energy and
potential energy.

8. a
Chemical energy is a form of potential
energy. Is the energy involved in the
bond formed between two atoms. Each
atom in a chemical compound involves
different amounts of energy.

9. Nuclear energy
Nuclear energy is the energy released in nuclear
reactions. We also refer to nuclear energy as the
energy by which we get other energies such as
electric, thermal or mechanical energy from
nuclear reactions.

10. Thermal or calorific energy
Thermal energy is heat energy produced by
burning a fuel, which may be solid, liquid or
gaseous, also obtained by electricity, by
friction, by nuclear fission ...
This energy is generated by the movement of
the particles forming the subject.
Thermal energy is the result of adding all the
mechanical energy associated with the
movements of the different particles that form
and unit of thermal energy is heat.
In the thermal energy, there are 2 types: the
heat energy and solar thermal.

11. Energy sources
Renewable energy
Non renewable energy

12. Renewable energy
It is called renewable
energy to the energy
obtained from natural
sources
inexhaustible, or the
immense amount of
energy they contain,
or because they are
able to regenerate by
natural means.

13. Non-renewable energy
Non-renewable energy
refers to those
sources of energy
found in nature in a
limited amount and
once consumed in its
entirety can not be
replaced, because
there is no production
or extraction system
viable.

15. POWER STATIONS
A power plant is a plant where some kind of
fuel is used in order to produce electricity.
In this way there are: thermal plants (using
steam or gas turbines), hydroelectric (using
water power by means of hydraulic turbines
and generators with automated operation),
nuclear, wind (using wind energy) and solar
(solar energy).

16. ABOUT WIND TURBINES THAT PRODUCE FRESH WATER
This report explains the process of how fresh water
can be produce from humid air by using wind
turbines. This project is very important, because if
it’s carried out, it could solve many problems, for
example: islands cannot centralized their water
supply, or some remote communities in arid
countries where water resources are scarce.
