> What is obsession with the light

Because the comment triggering this branch suggested improvements in efficiency must imply wanting to consume more. Light is one of those things, where the rule doesn't automatically apply. It's not the only thing I mentioned, you just chose to skip the others to make your job of arguing easier.

> Heating, cooking and appliances use the most

Even there you get more for less. Induction stoves are way more efficient than the old heating elements but do you want to spend more time in front of the stove because the electricity is cheaper? Some times, but not that common. Heat pumps are way more efficient than a boiler but it doesn't guarantee that you want hotter shower water or warmer room. But more importantly, most heating isn't electric. Natural gas, oil, or wood were always far more common. In the UK today almost 75% of heating is gas. Electricity is less than 10% [0] so it contributes little to the topic of the article.

Now let's get to the confounding factors which go down the pit of ignorance. Natural gas was always subsidized almost everywhere in the world whether you know it or not. District heating is more of the same. Where I live there are still "heating electricity" plans so people get a better price if they happen to use electrical heating because the provider knows that small number of people will suffer compared to others.

Another confounding factor, the push for extreme efficiency. Heat pumps have some big limitations that nobody wants but choose to live with for the sake of efficiency and self sufficiency. Because people also install solar panels on their roof and power their appliances without anyone ever reporting how much more heating or cooking was provided with 0 load on the grid.

In reality the biggest consumers which dwarf cooking appliances are industrial ones. And there the drop is real. Manufacturing moved abroad and electricity production moved with it. Maybe mass EV adoption can push the demand/production line back up.

> Seems like you don't live in the UK.

You are correct, I do not. This shouldn't prevent me from having an informed opinion though. Much like how I can write to you in English without living there.

Writing in English is one thing but the cultural divide between the US and the UK is enormous, so I think all the context counts for quite a lot.

I see things stated (and assumed as a norm) by people in this thread that are just miles off.

If you're working off data and not assumptions though, fair enough.
