It's part of the 'greening' of politics that everyone is supposed to put CO2-reduction at the top of the priority list, and that's the direction in which lip-service is generally paid. In this context, coal-burning is the universal enemy.
But when push comes to shove, and shove comes to parochial concerns - generally jobs - even coal (unabated coal!) gets the benefit of the doubt. The SNP - that's the SNP whose policy is "100% of Scotland's electricity from renewables by 2020" - are of course up in arms about Scottish Power's decision to close Longannet, one of the most heavily CO2-emitting plants in Europe.
And today we have Yvette Cooper, prime candidate for the Labour leadership (and of course MP for Normanton, Pontefract, Castleford and Knottingley), declaring: "dreadful news that SSE plan to close Ferrybridge C next year". Yes, that's another of those big, dirty coal-fired plants.
Perhaps she'll get asked at the hustings how she squares this anguished cry with her official support for the crazy energy policy that started with Ed Milibore's 2008 Energy Act. But probably not because there's no need, really: we all know the answer.
