Hydrogen is troublesome as an energy storage. The roundtrip efficiency (electricity -> hydrogen -> electricity) is just… very not worthwhile compared to batteries. Then beyond efficiency there is still the question of “how do we store hydrogen safely?”
Storing energy indefinitely is not a problem for electricity storage, since we are pretty much guaranteed to use the stored energy up in a single day.
It is all quite complicated.
A renewable producer (e.g. solar panels) cannot produce energy 24/7. And when it produces energy, you are not guaranteed the production is stable.
A consumer cannot consume energy 24/7. And when they consume energy, you are not guaranteed the consumption is stable.
To make the issue worse, a producer may not be producing energy when the consumer wants it, and vice versa.
Currently, energy storage is not widely installed. Hence any produced energy must be consumed at the same time.
The factors above combined means that there will be a mismatch. If the production is too great, your electricity appliances will probably explode and whatnot. If the consumption is too great, you experience blackouts. Neither are desirable.
Now consider there is a middleman. The grid. Producers sell energy to the grid. Consumers buy energy from the grid.
At some point in time, due to the factors above, the grid will need (A) zero to negative prices to encourage consumers to buy & use more energy from it, and to encourage producers to produce & sell less energy to it. Or (B) increased prices to encourage consumers to buy & use less energy and producers to produce & sell more energy. A flat price is not realistic. (Residential users only have a flat rate because our demand patterns are more stable.)
But due to the production patterns of renewable energy and consumption patterns of our society, there is a not-insignificant risk that renewable producers will consistently face scenario (A) above making it difficult to cover back the costs.
There are a lot more ways to store energy other than lithium and hydrogen.
Pumped storage, vanadium redox battery, sodium battery, … I’d even say they are most suited for grid-level energy storage.

Last time I asked around about this question, the answer was surprisingly “probably not much”! When a low-power x86 chip (like those mobile chips) is idling (which is pretty much all the time if all you are doing is hosting a server on it) it consumes very little power, about the same level as an idling Pi. It is when the frequency ramps up that performance-per-watt gets noticeably worse on x86.
Edit: My personal test showed that my x86 laptop fared slightly worse than my Pi 3 in idling power (~2 watts higher it seems), but that laptop is oooooooold.
I don’t think it is feasible to build one without a massive scope creeping. The grand strategies have very different focuses depending on the era.

If you squint your eyes just enough, insurance is like gambling… You are betting that something is going to happen to you, the insurance company is betting against that. The insurance company can improve their chances by adding conditions to that something.
Gen Z’s are well aware of traditional phones. Smartphones were not really that ubiquitous (up until 2010(ish)), and by that time Gen Alphas were already born.
I recall reading somewhere the earlier compilers had a hard limit on the length of function names, due to memory constraints.
One of the issues at hand is that X11, the predecessor of Wayland, does not have a standardized way to tell applications what scale they should use. Applications on X11 get the scale from environment variables (completely bypassing X11), or from Xft.dpi, or by providing in-application settings, or they guess it using some unorthodox means, or simply don’t scale at all. It’s a huge mess overall.
It is one of the more-or-less fundamentally unfixable parts of the protocol, since it wants everything to be on the same coordinate space (i.e. 1 pixel is 1 pixel everywhere, which is… quite unsuitable for modern systems.)
Wayland does operate like how you say it and applications supporting Wayland will work properly in HiDPI environments.
However a lot of people and applications are still on X11 due to various reasons.
LoDPI applications are either tiny sized or upscaled (= blurriness), aren’t they?
Yeah I get the display server part. What I meant was that 200% scaling gets you 1920x1080 logical resolution on HiDPI applications – LoDPI applications continue to be blurry just as if you set your actual resolution to 1080p, but HiDPI applications will enjoy the enhanced visual acuity.
Even on smaller screens like the 14" ones, the quality of very high resolution (e.g. 4K) is still quite visible IMO, especially when it comes to text rendering. But it could very well just be my eyes.
It’s not even Linux’s fault. Plenty of apps support HiDPI on Linux.
It’s the developers who still think that LoDPI-only is still acceptable when it’s already 2024.
Isn’t scaling to 200% the same as lowering the resolution to half? And you lose the high DPI for apps that support it too.
Agreed. HiDPI is the way to go and we should appreciate Framework for putting that in their laptops instead of continuing the use of shitty 1366x768 screens.
Xorg is the reason why OP is facing the scaling issues. OP, try to force the apps to run on native Wayland if they support it but don’t default to it. The Wayland page on Arch wiki has instructions on that. Immensely improved my HiDPI experience.

The modern electronic devices are far more railroaded than it was back in the day tho.
Want to download an application? There’s the App Store. No need to download random .exes from sketchy websites (and learn what a “computer virus” is the hard way)
Downloaded a picture? It’s instantly inside your gallery. Back then we needed to find a folder called “Download” or “My Documents” using something called the Explorer!
iPhone and Android made a lot of things dumber and easier to take in, but I feel like it had a detrimental effect on digital literacy.
I was agreeing with you at first – that the protest has no meaningful effects unless it is prolonged – but I stopped here:
Market socialism.
