CHRISTIAN Vassie is undoubtedly a good man who writes a good letter (Letters, June 16). So, I am cast as a fund manager: a sub-species – including bankers – currently not in vogue, but I am thick-skinned.

Occupying the LibDem’s green fringes is no excuse for failure to acknowledge the difference between ‘cheapest’ and ‘optimal’ solutions. Little wonder York’s great Lib-Dem experiment (2003-11) ended in tears.

A riposte to my letters became his fossil-fuel polemic; but I never mentioned them.

I wrote about nuclear power-generation, Germany’s switch to ‘sustainables’… and the dire economic consequences. Also the UK must be vigilant, given our uneconomic predilection for unreliable wind power; so not a truly sustainable enterprise.

From his comfortable armchair, Xian suggests Germany has demonstrated leadership with its (premature) switch from nuclear to ‘sustainable’ power: to hell with the price.

Let’s hold an ex-councillor panto at Christmas. Xian, playing Marie Antoinette as the Panto Queen can tell Germany’s good Burghers to eat brioche, not Ryebrot. Then, as frostbite sets in, why what a good job they’ve done to save the planet.

It’s a panto, so everything ends happily: bourgeois Greens everywhere, wearing their slippers can enjoy a warm, cosy feeling.
