OK so how much wind power and remember it does need backup unless you
have a unique storage idea?..

I don't have a unique idea, but....
There is a lot of pressure on the motor industry to develop an electric car
which can charge up all night and run round town all day. i don't know
enough about it to say for sure it will become a reality but if it does it
will have profound implications for this whole problem of delivering power
when you need it, not when the wind is blowing or the sun is shining.
