Admirable though the issue of regulations for sustainable homes is, I fear it is all a little too late when one considers the vast amounts of energy wasted in other locations.

The emergence of China as a developing power with a huge construction explosion merely adds to the farce. I however will continue to do my bit. Lower energy lightbulbs and a solar panel provide me with enough light and hot water, and save me £37 a quarter – and I’m still happy, if a little jaded.
