Why Miliband’s turbine building spree leaves Britain vulnerable to Putin’s missiles

Another security headache wind farms are causing relates to the country’s air defences, with the Royal Air Force concerned that turbines are interfering with radar signals. The problem occurs when their blades reflect the electromagnetic pulses pinged out to detect incoming aircraft and missiles, generating unhelpful background noise for the system operators. Each blade on a turbine can generate a false return, creating the potential for massive disruption from some sites. The first two phases of Dogger Bank, the UK’s biggest wind farm, boast 190 turbines alone. Professor Justin Bronk, an air power expert at the Royal United Services Institute, says the expansion of windfarms in the seas off northern and western Britain will be of most concern.
