While the acheivement above is very impressive and not to be under-estimated how this can benefit all of us in the future, there is so much we can do to improve existing housing stock.

When we had the survey prior to getting our solar PV array, we got an EPC band of C, thats pretty good for a detatched home built in 1966, the guy said the average is usually a D/E. We acheived it through increasing the insulation of the house, improving the heating systems, and installing low energy lighting, replacing old double-glazing units and such. We have not had a new survey, but the assessor said by installing the solar PV we should probably end up as a B!

So come on eco-people, dont leave it to the Earth-shippers to do it all!
