INTRODUCTION
Wind energy is an indirect form of solar energy, as are the differences in temperature and atmospheric pressure induced by the absorption of solar radiation which set in motion the winds.
today is primarily used to generate clean and safe energy. Formerly
used to propel marine vessels and move grain mills. Today is mainly used to generate clean energy.
is estimated that 2% of solar energy received by the Earth becomes kinetic energy winds.
The wind energy applications were limited to local uses, in isolated regions - to a power level of a few kW to tens of kW, or to a complementary role in food supply electricity networks - with levels power to a few MW.
The most favorable areas for the implementation of large wind turbines are the coastal regions and the Great Plains, where steady winds blow regularly: it is necessary to average wind speed exceeding 30 km / h. 
A
energy advantages
Wind power advantages over other conventional energy sources:
- should indirectly from the sun, which warms the air and causes the wind.
- is renewed continuously.
- is inexhaustible.
- is clean. Do not pollute.
- is indigenous and universal. There is worldwide.
- is becoming cheaper as technology advances.
- allows development without despoiling nature, respecting the environment.
- facilities are easily reversible.
A Cleaner Energy
Electricity generation from wind does not produce toxic gases, or contribute the greenhouse effect or acid rain. Each Kw.h electricity from wind power instead of coal, prevent the emission of a kilogram of carbon dioxide CO2 - into the atmosphere. Each tree is capable of absorbing 20 kg of CO2, generate 20 kilowatts of clean energy, has the same effect, from the point of air pollution, planting a tree.
TASKS 
know the topic doing work in which they answer the following questions posed, using the resources listed below.
Where does wind power?
- What amount of energy radiated by the Sun to Earth?
- Are all areas of the Earth captures the same amount of solar energy? How
- winds occur?
How wind energy is captured?
- How a wind turbine captures energy from the wind?
- what factors does it depend?
- What influence does the diameter of the blades at the energy captured by the wind? WTG
- What are the key components of a wind turbine?
- Types. Make a brief classification thereof.
How to measure wind speed?
- What is the name the devices that measure wind speed?
- drawing up a classification of them.
- How does the terrain on the wind speed?
areas and regions of greatest wind potential
- See a wind map of the peninsula. What are the areas of highest potential?
To work must follow the following steps:
1 .- Establishment of the group: In groups of two components. Their teacher will be to avoid conflicts, and foster camaraderie.
2 .- Distribution of tasks: Each student will pay for information about half the issues identified in tasks.
3 .- Search for information: Each group member will seek information on issues that have been allocated in the two types of sources listed: web or literature. This information will be collected in an orderly manner for further processing. 4 .-
Sharing Search results: The two members of each group will present the results of your search particular, deciding together what information (both graphic and textual) becomes part of the work and what is discarded. 5 .- Making
end of work: work is drawn up using the word processor available in the center. RESOURCES

ASSESSMENT
must give the teacher the results of your research. An evaluation of the same according to the following criteria:
- points for the job.
- Using the proposed links for the job.
- level synthesis of the information found on the web.
CONCLUSION
With all the information you can find something you can learn more about new technologies, especially wind power.
