So, the subsidies have flowed, the markets are rigged, the countryside has been besmirched with windfarms, the coal-fired power stations closed or switched to biomass and the rooftops have been tiled with solar panels.
And the result?
The Scottish Government has missed its greenhouse gas emissions target following a rise in pollution last year.
It means a massive turnaround will need to have been achieved in 2013 – a reduction of around 13.8% – to get back on track.
And Opposition Tory MSPs have urged the government to use nuclear power and allow shale gas drilling to help Scotland meet its self-set targets.
The scale of emissions across the country increased by 0.8% to a carbon dioxide equivalent of 55.665 million tonnes.
The target for 2012 was 53.226 million tonnes, while greenhouse gas levels in 2011 hit 54.252 million tonnes.
