According to The Committee On Climate Change report, they recommend a ban on Gas boilers for home heating, in all new houses built after 2025. Talk about cat and pigeons?

'The water could be heated by waste heat from industry'. quote from the BBC report.
Who are these muppets, we don't really have any industry left to produce waste heat -- same as we don't have much industry left to train all the apprentices that have suddenly become flavour of the month again after a gap of 30 to 40 years where no-one has been trained ( except as plumbers or gas fitters, tattooists, and hairdressers and tanning salon assistants ).
We missed a great opportunity to use waste heat from power stations ( like the Russians have always done) to heat local houses ( when we actually had power stations that is ). Problem with ground source heat pumps not everywhere is suitable, and while air heat pumps are quite economical ( about 2:1) they are nowhere near as economical as ground source ( about 4 or 5:1 ).
A gas boiler working at 90% efficiency is a better alternative than using electricity from a gas fired power station at a much lower efficiency when generating and transmission losses are part of the equation.
Government and experts keep talking about global warming but once again over-population is never mentioned because big business ( who now have governments on their payroll ) need an ever-expanding population as a market for their goods.
to me 'expert' can be broken down into two parts
ex = former / used to be
spert ( spurt) = a drip under pressure
