wind energy survey

1- what do you know about wind energy ?




2- Do you think wind energy is cost effective ?





3-  Do we need more wind farms ?




4- Is wind energy clean source of energy ?




5- Should we develop wind energy ?




6-  Do you think the production of wind energy is enough ?




7- Are the advantages of wind energy more of its disadvantages  , and why ?




8- Should we use  small wind turbines over houses or buildings ?



9-  Countries that do not have fossil fuels should they use wind energy ?



10- Within the future developments, do you think wind energy will be efficient ?



11-  How can we reduce the cost of building wind turbines ?



12- Any further comments ?

CLO PHASE 2

Justification:
Wind energy is one of the renewable energies, and it's a clean one, not like fossil fuels but it's not cost effective, so we need to develop it to get more benefit and reduce its cost; then a lot of countries will adapt this idea, mostly the countries that do not have fossil fuels or gas so as a result of developing we will get more energy and reduced rates of co2 in the air which as a result will decrease global warming effects, so in the future our new generations well have more options of energy with reduced costs and also better environment and better health that we have now, so developing this energy well help us in many fields.

Source 1 :
How to make wind turbines more efficient , information about the best design for each place
Description:
This webpage talks about the design to work best with the aerodynamic efficiency, like the design for farms is different from the design of designs for offshore. Also reducing the weight of the rotor blades and they must be twisted  to get more speed, and the height of the tower itself.

Source 2 :
How to reduce wind farms costs, tips and advice to reduce the cost of each wind turbine
Description :
this site describes the new technology that will be used to reduce the cost of wind turbines which is called circulation control; as an example, this method will eliminate the complexity of wind turbine blades. Also this thing will allow us to use new geographic places and as a result wind farms will expand .

Source 3 : How to build a wind tribune in home as they say homemade steps and tools.
Description :
this web page will explain how to make wind tribunes; there are three initial parts: first the generator that changes the mechanical movement to electricity; also the blades that capture the movement of air which needs to connect to moving parts; finally the tower which needs to be placed a little bit high.
