RENOVABLES Y
LIMPIAS
renewable and clean energy.

2. WHAT THIS?
 Renewable Energy is simply energy from a
source that isn’t used up when the energy is
consumed.
 Several types of renewable energy among the
most common are:
 Solar
 Wind
 hydraulics
 Among other

3. renewable and clean energy is
the same?
 Renewable energy and clean energy have
something in common, used to generate energy
or electricity and do not pollute, but they are not
exactly the same.
 Renewable energies are leveraging the sources
that nature has given us
 Las energías limpias son aquellas que cuando se
usan no generan residuos tóxicos que dañan al
medio ambiente, el gas natural por ejemplo es un
ejemplo de energía limpia

4. advantages and disadvantages of
using renewable energy
advantages

Clean energy, as its name
suggests, do not harm the
environment.
 do not cause the emission
of polluting gases into the
atmosphere
 They do not contribute to
climate change effects
disadvantages
 its poor
implementation

5. advantages and disadvantages of
using clean energy
advantages

These energies do not
pollute
 They are inexhaustible
and diverse
 Do not produce
greenhouse gases
 Produce no nuclear
risk
disadvantages
 It is very expensive and
unapproachable produce
these energies
 All biofuels produce more
carbon dioxide
 Geothermal energy is
considered polluting and
is very restricted
 A great impact on our
landscape

6. countries with the highest number
of renewable energy
 1. China. Its economic development requires a
tremendous amount of energy, based largely on
fossil fuels. The Chinese authorities are
increasingly aware of the consequences for the
environment and the health of its citizens, and drive
for several years the growth of renewables.
 U.S. The share of renewable generation increased
in 2013 to almost 12.9%, despite a drop in
hydroelectric power.
 Brazil. In addition to its enormous potential in
hydroelectric generation, Brazil is betting on other
types of renewables.

7. wind power
 Wind power is the energy from wind, ie the
kinetic energy generated by the effect of air
currents, and is transmuted into other useful
forms of energy for human activities.
 in mexico oaxaca it produces 90% of the wind
energy

8. solar energy
 Solar energy is the energy produced by the sun and is
converted to useful energy by humans, either to
produce electricity or heat something (like its main
applications).
 Solar energy is a clean and renewable energy offers
many advantages. However, not all are benefits and
there are aspects of this energy that are still
improvable.
 The intensity of energy available at a given point on
earth depends on the day of the year, time and latitude.
In addition, the amount of energy that can be collected
depends on the orientation of the receiving device.

9. Hydropower
 Hydropower is produced by the water retained
in reservoirs or swamps high
 It is a source of clean energy, no waste and
easy to store. In addition, the water stored in
reservoirs located in high places can regulate
the river flow.

10. Geothermal energy
 Geothermal energy is produced by the
internal heat of the Earth that has been
concentrated in places underground known as
geothermal reservoirs, that if well managed,
can produce clean energy indefinitely.

11. Computing in renewable energy
 The computing has to do because
this helps us to develop new
technology applications and improve
renewable sources.
 The computing also responsible in
part to check that works well and that
no harm will not occur.
 Check out the following video

13. materials dealing in computing
and to produce energy are:
 optical fiber
 semiconductors
 superconductors
 new ceramics
 new plastic
 light alloys
 special glasses

14. THE END
 both renewable energy and clean computers
need to function in the future improved and
thanks to that we can live in a much better
place.
