You obviously didn't live in London and go to school in the 50s. We used to put a scarf over our nose and mouth (which were covered in muck where we breathed through) and truly there were smogs where you couldn't see 4 meters in front of you on the way to school (though we talked in yards, in those days) .
Insulation of every house would do a lot to reduce fuel poverty, which I think is the only legitimate grumble. It would also create proper jobs. I cannot understand why the green deals are turned on and then off, just when installers are trained and companies have a full order book. We benefited from a green deal grant to insulate the walls of our maisonettes, massively increased the comfort of our tenants, ended the condensation and mould in the cold corners and dramatically reduced their energy bills. (They never even said thank you!)
When we were in school our science teacher was a nuclear skeptic, he said if every home had a thatched roof we wouldn't need nuclear power.
