I can't speak for the UK, but A big thing is that in the last 20-25ish years at least in a US home the big ones for me as far as efficiency improvements are

- CRTs got replaced by LCDs, and LCDs even 25 years ago were maybe around half the wattage

- CFLs and then LED Light bulbs replacing older filament bulbs.

- The switch from desktop PCs that might take 100-200W before even considering the screen, to Laptops that might use 50W on average.

With the smaller thought of:

- Set-top appliances like rice cookers and air-fryers that tend to be better for smaller everyday cooking than a full-on oven or stovetop.

And it's fun to think about, e.x. I remember when I had to move back in 15-ish years ago my parents (very politely!) complained about the power bill increase until I went ahead and did the one-time cost of switching all the bulbs I could to LED. That change alone managed to cover the PC, monitors, and TV I had at the time.

Realistically, your average citizen is using less power than they were even 40 years ago, even with all the additional technology they have.

It's not a good look that the UK seemingly isn't installing air conditioning, decarbonizing heating, or adopting electric vehicles. Efficiency is good after you have high living standards but the UK should probably focus on growth first.
reply
It comes from an idea that economic progress is coupled with increased energy use, a fallacy that hasn't been true for decades, even for fossil fuels. It's well established that the cheapest additional capacity is efficiency. One of the reasons I am not so concerned about the AI energy needs, especially because the US has a lot of wiggle room.
reply
There's a lot of HN and YC-aligned people who don't believe this, despite the empirical evidence of the last few decades.

To take the stupidest version of the argument (not going to sugarcoat it, I think it was embarrassingly stupid) there was Marc Andreesen's Techno-Optimist Manifesto where he called for a 1000x increase in energy production from nuclear fission and fusion. I quote directly:

"We believe energy should be in an upward spiral. Energy is the foundational engine of our civilization. The more energy we have, the more people we can have, and the better everyone’s lives can be. We should raise everyone to the energy consumption level we have, then increase our energy 1,000x, then raise everyone else’s energy 1,000x as well."

reply
Driving energy costs to near zero drives down the cost for literally every other process, manufacturing or extractive or services. A 1000x increase in energy practically lets you extract so much material for cheaper that the cost of materials, and the associated logistics, goes down.
reply
That is self-evidently true but misses the point.

The point of using energy is not to use energy. What matters is the services that energy delivers, be it a hot shower, a drive to the grocery store, a new house, a squillion tokens of AI computation. If we can get the services we want more cheaply by energy more efficiently, this is a good thing, not a disaster for humanity.

For completeness, I acknowledge that there are people for whom energy usage is inherently bad, which is equally silly. What matters are the downside impacts of the energy use, not the energy use itself.

reply
Well given that cheap energy follows Jevon's paradox, it makes complete sense. If each unit of energy becomes cheaper to produce (which renewables are driving today), then you should see more consumption of that cheap energy into economic activity. Economic progress is easily coupled with increased energy use.

The US has a lot of wiggle room wrt energy consumption because it has ceded the role of being the world's factory to China. At the same time, the US is the world's data center and software development hub, and the world's finance hub, and the world's bank. What does the UK have in comparison?

> There's lots of amusingly Telegraph-esque outrage here. But the article makes it clear that the reduction is due to reduction in demand, due in part to improvements in efficiency, but also regrettable deindustrialization, and increased importing of electricity

Right – those things aren't great. What's so amusing or outrageous about pointing that out?

> Nobody is planning to ration electricity suppies.

Did the link say they were? Maybe I missed it.

reply
The Telegraph-esque outrage in the comments here is explicitly people complaining about the idea of rationing their electricity, which as you point out is not suggested by any part of the article.
reply
There are comments here saying yes, rationing is planned.
reply
I don't see any evidence for that. Just people saying it.
reply
To be fair, the people who think it believe that smart meters are how it will happen, so their existence would be all the evidence they actually need that it will.

I have no view either way (or a smart meter)

reply
Smart meters themselves aren't the problem. It's meters that can control HVAC.
reply
There don't seem to be any comments on this thread referring to rationing.

And FYI energy rationing has been one policy consideration for decades.

UK gov energy rationing proposal [1] 'Personal carbon allowances [2]

There's always discussion about this sort of thing, it's not fear mongering to point out that fact.

Trivially falsifiable statement, just read the comments in this thread:

https://news.ycombinator.com/item?id=50076266

>> But their great idea to deal with the shortage is intermittent availability of power.

In other words: rationing.

reply
One possible reference to rationing - that is actually not a reference to rationing - does not infer that the thread is loaded with Telegaph-esque rants about rationing.

You're doubling down on the misrepresentation.

There are zero references to rationing on this thread - and yet the top commenter calling this out as some kind of 'Telgraph-equ' nonsnes.

'Intermittent availability of power' - is absolutely not a reference to 'rationing' and if it were, it wouldn't be any kind of basis for hyperbole over 'rationing'.

I gave evidence of two examples of govenmental policies around rationing, and it's definitely not via 'power outages' - that's absurd - rolling blackouts only happen during emergency situations.

You've stated that the conversations has tilted to 'rationing' is 'trivially falsifiable' and at the same time haven't produced any evidence.

reply
> Did the link say they were? That seems like a red herring.

By "here" I meant posts on this thread, not in the content of the article.

reply
Thats a basic misrepresentation though. And the condescending fear mongering out 'telegraph-esque' does not help.

The quote is:

"Deindustrialization has reduced demand,"

Leaving out 'Deindustrialization' is leaving out most of the story.

That is the gaph of industrial decline.

It's not that the 'dishwashers' are using less electricty so much as dishwashers are no longer designed and made in the UK. That is the story.

Probably less than 20% of that curve is 'green good news' - 80% of it is deindustrialization which is a primary economic malaise.

That deindustrialization is now starting to hit 'core' industry like auto - and a fundamental driver of the far right.

Industrial use of electricy is about where it was in the 1980s because industry ha moved elsewhere, like China.

AfD cannot get enough votes without that curve - Mercedes is closing down while China expands. That's the story.

reply
> Probably less than 20% of that curve is 'green good news'

I would call this a basic misrepresentation, but you just pulled that number out of thin air. Or somewhere worse?

50% of the decline is from industry, 50% from residential[1]. During that timeframe, industrial output increased.

[1] gives different numbers. About 3x decrease in industrial energy consumption since 1970. Steel production decrease is about 3x ([2]). Chemical production has shifted from bulk production to pharmaceuticals.

That’s a different metric - “million tonnes of oil equivalent”. That’s not the same as electricity consumption - that’s the total amount of energy used in all kinds of industrial processes.
reply
The data across the board supports the notion that reduction in electricity is an industrial phenomenon overall, there is no data to suggest this is a 'consumer green activity' phenom - not even the link you provided.

All of think links here, the person you are responding to, mine (above) and your own directly point towards reduction in industrial use.

reply
Rather than post incessantly about the vague “across the board data” and “probably X and Y” you could always cite a source.

Just a thought.

reply
No, literally the evidence you provided does not support the 50/50 thesis, moreover, the data does show that residential reduction is a marginal - and you're probably failing to take into consideration the UK has grown by more than 10M people during that period aka this is 'per capita' - not aggregate.

This government data is must more substantial than that link, and it puts the ratio at 70% reduction in electricity due to deindustrialization.

Moreover - the OP's comment was a blatant misrepresentation (lie) - by ignoring deindustrialization, the primary factor as stated in the article (and in reality) - plus a bit of a thrown slander aka the 'Telegaph-esque' nonsense.

This is not Twitter.

This is not even controversial.

Industrial usage fell about 100k TJ, household fell ~110k TJ since the peak.

The linked numbers are not per-capita, they are absolute.
