Wind Power

Energy sources of most impact to the environment are coal and hydrocarbons which mainly affect water bodies, soils and wildlife, and human health.

Minihidroeléctica: The exploitable hydropower potential in Mexico is significant although its use is low and is concentrated mainly in the south of the country where water resources are abundant. The proportion of this energy is zero for public purposes.



Wind energy: Energy obtained through wind turbines convert the kinetic energy of the wind into electricity through a turbine. The main areas of greatest wind potential.


Solar energy: For the exploitation of this energy source available thermal and photovoltaic systems photo. The photo thermal systems convert solar radiation into heat and transfer it to a working fluid, the heat is then used to heat buildings, water, power turbines to generate electricity, dry beans or destroy hazardous wastes.





Renewables are generally more expensive to produce and use than fossil fuels. Besides other factors, renewable resources are often in remote areas, and is expensive to build power lines to cities where it is needed the electricity they produce. The use of renewable sources is also limited by the fact that not always available - cloudy days reduce solar energy, calm days reduces the power of the wind and drought reduces water available for hydropower.





If you are in Mexico, the main wind resource in Mexico is located in the Isthmus of Tehuantepec, in Oaxaca. In windier areas (Sale), the annual average wind speed at 50m height exceeding 10m / s in the coastal plain where there are also areas with high winds, moderate and low.
