Here is something that Aussies should consider, an issue which has arisen here in the UK regarding wind turbines, at least offshore wind farms. It has been found that the wind turbine blades interfere with radar signals. UK fighter pilots knew this for some time and would in training exercises fly into wind farm areas knowing that the blades’ rotation would interfere with radar detection.
Now the UK air force is seeing a problem here with the growing number of these wind farms, as Russian ships had been observed mapping communication and power cables in the North Sea earlier this year. It is likely that the growth of offshore wind farms is set to be a security threat.
