I think we need a fundamental change in how we cook and heat homes. Our housing stock is terrible and houses built as cheaply as possible rather than with the long term cost of ownership taken into account.
How inefficient is oven and hob cooking - all the wasted heat.
We need to radically look at how we keep food (fridges and freezers) how we cook it and how we heat our homes and provide hot water - it is all very inefficient at the moment.
Then you add on how we use electricity in the home - or rather waste it with hairdryers and stylers, phone charging and other electronics, the way TVs and so on use electricity as well.
I am terrified of the bills and we are having a new more efficient boiler fitted (alth still LPG unfortunately) we will have solar and batteries installed and I will be looking seriously at all our electronic equipment and asking what we can do without.
We have actually been spoilt over the last 30 yrs or so regarding the cost of these essentials.
