Wind Turbines only have a working life of 20 years, so are not sustainable. They require huge amounts of energy to produce their metal casings and the cement used in their construction. One 320-feet high turbine requires 150 tons of cement and 300 cubic metres of steel lining and shuttering for a massive hole some 100-feet deep in order to provide enough support to resist and stabilise the massive torque generated by the spinning blades. Access roads to the site and for each turbine must be able to bear heavy traffic.
The turbines only work a maximum of 29% of the available time and are currently subsidised by £1.5 billion annually from taxpayers' money. When the subsidies cease, much more expensive electricity bills for every householder and business can be anticipated. Danish electricity, after their loss of subsidies, is now 12% more expensive thanks to their turbine policy which has also shown itself to be woefully inefficient. British industry is not even benefiting from their construction! The turbines are manufactured in Denmark or Germany!
Conventional power stations will still have to be relied on and kept working, ready to take up the shortfall, because turbines can only operate between wind speeds of 10 - 50 miles per hour.
The Government has also ignored the huge costs of upgrading and supplying extra national grid power lines which will be needed for all the extra turbines.
