Tipos de energia renovables e impacto ambiental de estas.

1. NEW ENERGIES
NICOLE DAYANA OCAMPO S.
KAREN ANGELICA CUERO PAZ.
11-2

2. RENEWABLE ENERGY
Renewable energy replaces
conventional fuels in four distinct
areas: electricity generation, hot
water/space heating, motor fuels,
and rural (off-grid) energy
services.
Ex: the wind, geothermal, hydro,
tidal, solar, wave, biomass and
biofuels.
Sunflower icon of
renewable energy for its
massive use of solar light,
use for biodiesel and
"similar" to the Sun

3. ALTERNATIVE ENERGIES
OR GREEN ENERGIES
Alternative energy is
those that can supply the
energy or current energy
sources, either by its
lower polluting effect or
primarily for its possibility
of renewal.
Ex: wind energy, biofuels
and solar thermal energy

4. WIND ENERGY
Wind energy is the
energy derived from
wind, that is, the kinetic
energy generated for
the effect of air
currents.

5. BIOFUEL
Biofuel is a mixture of
hydrocarbons that is used
as fuel in internal
combustion engines
Ex: The beet, Sugar cane
produce ethanol, maize and
cassava.

6. SOLAR THERMAL ENERGY
It involves collecting
the sun's energy
through solar panels
and convert it into
heat which can be
used for many needs.

7. HYDRAULIC ENERGY
It is called
hydropower, to that
obtained from the use
of kinetic and potential
energy of the water
stream, waterfalls and
tides.

8. WAVE ENERGY
Wave energy it is the
energy that allows the
production of
electricity from
mechanical energy
generated by the
movement of the
waves.

9. BLUE ENERGY
Blue energy is the
energy obtained by the
difference in salt
concentration between
seawater and river
water. This renewable
energy has great
potential in regions with
flowing rivers.

10. ENVIRONMENTAL IMPACT
• They replace the use of
fossil fuels significantly
reducing the impact
environmental
.Are inexhaustible or they
can renew soon
• They generate wealth
and quality jobs so direct
and indirect.
• In the vast majority of
cases it is reducing
reliance on indigenous
resources Energy to third
countries.

11. ENVIRONMENTAL IMPACT
Have generated new devices friendly to the
environment.
Ex: Solar toys,electric car or solar car, solar
panels, water bulb, inter alía.
