yup


banning gas boilers only makes any sense when 100% of UK electricity
production is carbon free


It can make sense to reduce local pollution.

until it is, simply transferring gas use to additional electric use is
just daft


What is daft is charging a higher price per kilowatt of electricity than
gas.


That's mostly down to the second law of thermodynamics.


Efficiency = (input temp - output temp)/(input temp) for a heat engine.


A gas power station is 30-50% efficient, the rest being waste heat
unless you can use it for something like district heating.


If that is the case, burning it directly to heat our homes etc makes more
sense.
