Wind farms are inefficient, only working at their design capacity for a fraction of the time and are unsightly, despoiling HUGE tracts of previously unspoilt, wild, desolate, beautiful wilderness . That feeling of "getting away from it all" , so important for the mental well being of millions of ordinary people, would be lost.
They are also extremely noisy for people living close to them.
Where they are built invariably tends to be in isolated rural areas. Which are deathly QUIET at night. So regardless of the low , by industrial standards, decibel rating, nobody can get to sleep!
Again, detrimental to health, increased cost to the NHS and a probable productivity loss to the nation.
Because they cannot ever provide enough power for the future needs of the UK, especially in winter, when we need more power than at any other time, (Winter wind is of much lower strength than at other times of the year), they need to be "backed up" with conventional power stations.
These (coal, gas and nuclear), need to be kept running at all times. They cannot just be switched on or off at will.
So their ( the wind farms ) existence is an uneccessary duplication of power generating capacity.
Why is this idea important?
If cars and trucks need to be electrically powered, either using batteries or hydrogen fuel cells, (both drawing current from the Grid), we will need a lot of electricity.
An awful lot. So much electricity that there is only one way of producing it. France is 78% nuclear already, and still increasing. The French do not have two heads each.
