Wind Power 4 All

It's for a project.
What are the pros and cons of using wind power?

b&q are selling wind turbines can any one tell me how they are connected to the house supply as they dont come with meter to sell back to electric supplier

www.greenpowerscience.com A simple wind turbine all around you.

i know nothing about it and would like some info for “dummies”. Who it work , who to install etc…?
anybody?

I am doing a science project and I am completely confused. I have no clue what sustainability means and how it connects to wind power. Any help I would appreciate.

Showing:

Wind needed to meet demands and then data from a certain period of time, showing wind speed and power produced?

Thanx in advance.

Obviously windmills extract some power from the wind using blades that rotate etc, but I wonder if it would be possible to get energy from the wind by mimicing the rocking/swaying motion of trees on a windy day?

I believe that larger windmills with a larger area of blade space exposed to the wind will spin with less wind speed. A tree or something like it provides a lot of space for a less powerful wind to push against…so…would it be possible to construct something like a sail on a hinge to extract more power at lower wind speeds?

I apologise if this all sounds like nonsense. I’m not a scientist, hence the question and I’m guessing that windmills work in a way that is more efficient than my oddball suggestion/idea.

What do you think anyway?

Is this nonsensical or impractical?

Any thoughts/comments appreciated.

Thanks

What is keeping wind power from widespread use and when is it expected to be easily accessible to the general public?
