I'm trying to improve the energy efficiency of my Edwardian house so any help with that would be greatly appreciated. I'm lumbered with a diesel car and am finding it hard to work out what is the best thing to do now that the emissions have been found to be far worse than petrol after all. So any thoughts on that would also be great.

I'm happy to help with general mitigation issues, shopping, waste, second life, repair and reuse, real nappies, alternatives to disposables in general, the Climatarian diet, getting a meat loving family to cut down and eat more veg, home solar energy installation.
