Bryony Worthington, the environmental campaigner who was ennobled by the last government and then proceeded to run amok through UK energy policy, has penned a critique of Dieter Helm's book on solving the UK's energy problems. Helm's objective is to do this without actually trashing the economy or killing off too many old folk.
Worthington's approach is rather different of course. She notoriously favours only hair-shirt policies on energy - if objectives are achieved without any pain they don't count in her book (see here). It's therefore hard to take her views on anything terribly seriously. For those who want a laugh, she seems to think that subsidising technologies that don't work is the way forward.
