These people are idiots. One wonders if they actually realise they are calling for all of the nation's 26 million gas boliers to be removed within a short timescale. None of the industries concerned could possibly cope, and many of the home owners concerned cannot afford the change. Electricity costs about four times more than gas too, so a typical heating bill would rise from £500 a year to £2,000 a year. And that assumes that the electricity generators can cope with that kind of demand. They cannot, obviously.
The extra 17,000 wind turbines (which would not work in a storm or on calm days) would require us to devote an extra area of about three times the size of Wales to wind-powered generation. And build it all in five years (while getting rid of the gas boilers, of course). Is that realistic?
The simple way to deal with those who glue themselves to things is to yank them off.
