Ron McKay's Diary: Is 'It's Scotland's wind!' the next SNP war cry now that oil has become an ecological affront? A child at Whitelee Windfarm in East Renfrewshire, the UK's largest onshore wind farm, as the Scottish Government said an emergency summit convened in the wake of Westminster's decision to scrap a subsidy scheme for onshore wind farms was It’s Scotland’s wind! I don’t expect we’ll see that slogan from the SNP in future elections (or referendums) as oil figured in the 1970s one, before it began to run out and also become an ecological affront. It’s currently at just over half the price – $68 a barrel – which, in 2014, economist Andrew Wilson predicted in the White Paper would have a robust and “baked-in price” of $112. Which only goes to prove that economics is too important to be left to economists.
