So, most estimates agree for the UK it will take about 3 times national GDP investment to build the infrastructure needed to go all electric. It will take 50 years to build.
Now, we have to tackle all the poorly insulated homes in the UK so they can actually use less energy / require lower BTU to heat. Nobody knows how much that would cost, which is probably more than updating the infrastructure. It will take a long time, simply not enough trades to carry out the work.
So in summary, to go green the UK cannot afford it, can’t do it in time and hasn’t the trades to complete it.
The view of me, one of the unwoke (my preferred pronouns are sensible, realistic and fact based) is that lots will be spoken about climate change and CO2 but the harsh reality is that we won’t do anything about it.
