This is my Class work

1. Wind E nergy

2. Introduction - Definitions - B asic parts - H ow does it work ? - A dvantages - Disadvantages - P roduction in europe - Around the world - C onclusions - Others - C redits

3. D efinition Definition : the wind Energy is the Energy derivered from wind , used to generate mechanical power o r electicity .

4. Basic P arts .

5. How does it work ? 1ºst: The wind move the rotor blade 2ºnd: The rotor blade move the gear box 3ºrd: the gear box rataate 50 times tha the ususal and create mechanic energy 4ºth: the genator transform the mechanic enegy to electricity 5ºth: the elctrycity go trougt the power cables to the transformer and then to the swichards .

6. Advantages ADVANTAGES - The wind is free and with modern technology it can be captured efficiently . - Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants . - Although wind turbines can be very tall each takes up only a small plot of land. This means that the land below can still be used. This is especially the case in agricultural areas as farming can still continue . - Many people find wind farms an interesting feature of the landscape . -  Remote areas that are not connected to the electricity power grid can use wind turbines to produce their own supply . - Wind turbines have a role to play in both the developed and third world . - Wind turbines are available in a range of sizes which means a vast range of people and businesses can use them. Single households to small towns and villages can make good use of range of wind turbines available today.

7. D isadvantages DISANDVANTAGES - The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. There will be times when they produce no electricity at all. -Many people feel that the countryside should be left untouched, without these large structures being built. The landscape should left in its natural form for everyone to enjoy. -Wind turbines are noisy. Each one can generate the same level of noise as a family car travelling at 70 mph. -Many people see large wind turbines as unsightly structures and not pleasant or interesting to look at. They disfigure the countryside and are generally ugly. -When wind turbines are being manufactured some pollution is produced. Therefore wind power does produce some pollution. -Large wind farms are needed to provide entire communities with enough electricity. For example, the largest single turbine available today can only provide enough electricity for 475 homes, when running at full capacity. How many would be needed for a town of 100 000 people?

8. Production in Europe

9. Around the world

10. C onclusions My conclusión is the wind Energy could be improved but its a good renewbable enegy but it generates low Energy and it depends on the wind if theres no wind this not generate power

11. O thers - Humans have used wind energy since he learned to sail boats to sail . -The first windmills were used to grind grain in ancient Persia.

12. O thers -Each year the production of wind energy is enough to provide all the energy needs of the city of Chicago.

13. O thers It needs to cover 13% of the land in the world with wind turbines to supply energy to everyone.
