THERE’S a sign at the NorthLink ferry terminal in Lerwick saying ‘Protect our islands from invasive non-native predators’. It’s about biosecurity, not wind farm companies, but that’s exactly how the Shetland Charitable Trust’s former business partner and some of its fellow corporations are now regarded. But when the petroleum industry’s hangers-on turned out to be invasive predators, with merchant bankers (for example, the much-praised Ian Noble) using local entrepreneurs (such as Ian Caldwell) as front men for speculation in land, publicity about their clandestine financial manoeuvrings turned the tide of local public opinion. Because of its large scale, the Viking planning application went before Scottish ministers, not Shetland councillors. Clearly, we need to stop all new wind farm developments now.
