Homeowners will have to turn down radiators by 10C if Britain is to hit climate change targets | Daily Mail Online

It really is time that the Government took some advice from Engineers. All of these "everything electric" plans are completely unworkable without the replacement of the entire electrical distribution system and 10 new nuclear power stations. The cost £3 trillion. By 2030, you have to be having another laugh at the public. Air source heat pumps sound ok on paper until you understand the specification. With air at -10C (not unusual in Britain) and 50C outlet temperature they perhaps give 2 times the heat available from electricity directly. The electricity costs 4 times as much as gas, guess what, you pay twice as much money to run a complex system which is expensive to maintain! The article above is Green rubbish, no truth whatsoever. As for Hydrogen, forget that, it needs twice the electricity to make it as the heat from burning it. Simple chemistry, not understood by the new "Green" Government.
David CEng etc (Thats a real Engineer by the way!)
I got another Engineers reply
@David Stone
As another real Engineer I completely agree. Unfortunately the entire government is technically and scientifically illiterate, something that ministers actually seems to revel in. They like to say that they are led by the science but that is simply not true. They are led by dogma. Having "green" taxed electricity to the point where it is uneconomical for high power applications such as heating and transport they now want to mandate it as the only energy source that is "green", which, of course, it is not.
It is not just the Mail!
