Energy efficiency in homes to reduce CO2 emissions?

No point in changing energy effeciency of homes. LOOK AT ALL THOSE TRUCKS!! The stupid EPA doesnt put strict regulations on their emissions.

I seen a chap with solar panels on the roof of his van. he used them to charge three batteries that in turn charged all his power tools he used in his job as a mobile joiner. I looked into installing a system in a house using 12 volt lighting and a battery accumulator system to run TV, fridge etc. I found the cost would be around £10,000 and you need a licence and a system to put surplice power back onto the national grid. Economics show that the cost x return make this at present not economic option. However if prices keep rising it will be in a few years.

With the scale of new housebuilding in Britain there is plenty point in CO2 reduction methods. It should be legislation that all new builds are thoroughly insulated and have a form of micro energy production - ie windmill or solar hot water etc. This is in line with Greenpeace's campaign on decentralised energy - that we shouldn't just be supporting large scale windfarms and projects, (as with all large scale private developments, there will be badly thought out ones) but localised means of energy production which avoid the need for centralisation and use of pylons and miles of cable - which lose up to 1/3 of energy in transporting it to our homes.
