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.

ALTERNATIVE ENERGIESOR 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
WIND ENERGY
Wind energy is the energy derived from wind, that is, the kinetic energy generated for the effect of air currents.
BIOFUEL
Biofuel is a mixture of hydrocarbons that is used as fuel in internal combustion enginesEx: The beet, Sugar cane produce ethanol, maize and cassava.
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.
HYDRAULIC ENERGY
It is called hydropower, to that obtained from the use of kinetic and potential energy of the water stream, waterfalls and tides.
WAVE ENERGY
Wave energy it is the energy that allows the production of electricity from mechanical energy generated by the movement of the waves.
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.
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.
ENVIRONMENTAL IMPACT
Have generated new devices friendly to the environment.
Ex: Solar toys,electric car or solar car, solar panels, water bulb, inter alía.
