In our weekend review, the redoubtable broadsheet columnists grapple with the pending green fatigue by talking about the most practical thing they can think of: energy production.

Nick Cohen in the Observer accuses the green hardline of imperilling our energy supply and increasing the risk of a green backlash while economic conditions worsen.
