cloudie78··on Italian parliament votes for return to nuclear energy
Okay yeah as expected some people seem to be too fucking dumb, so I’ll expand a bit, in case someone bothers to read this later.

There are several different concepts being collapsed together here.

“Baseload is a myth” is mostly a semantic dodge. Base load is simply the minimum demand on the system. You do not need a special category of plant called a “baseload generator,” but you absolutely need enough firm capacity and energy to meet demand continuously, including when wind and solar are producing very little.

“The grid can handle peak load, therefore it can handle base load” confuses transmission capacity with generation availability. A grid capable of carrying 50 GW does not produce 50 GW. The engineering problem is having enough generation available at the exact hours when it is required.

And batteries do not make that problem disappear. They are excellent for frequency response, peak shaving and moving solar production from noon into the evening. But a battery is an energy buffer, not an energy source. During a prolonged shortage it can discharge only what was previously stored, and then it must recharge. Once the problem lasts several days rather than several hours, the amount of stored energy required becomes enormous.

Germany provides a very useful real-world example.

Germany began its nuclear phase-out under the 2000/2002 agreement, briefly extended reactor lifetimes in 2010, then accelerated the shutdown after Fukushima in 2011. The final three reactors closed in April 2023.

In 2008 German nuclear plants produced roughly 149 TWh of electricity. Germany subsequently built huge amounts of wind and solar, and those renewables have unquestionably displaced a great deal of fossil generation. But Germany eliminated its existing firm, low-carbon nuclear fleet while it was still burning very large quantities of coal and gas.

And then there is the problem Germans have an excellent word for: Dunkelflaute.

This is not some hypothetical edge case invented by nuclear advocates. Germany’s Bundesnetzagentur defines a Dunkelflaute as a period of at least 48 hours during which combined wind and PV generation remains below 15% of installed capacity. Low-wind periods are recurrent; analysis of four decades of German weather data found roughly a five-day period with average wind output below a 10% capacity factor in a typical year, with substantially longer events occurring less frequently.

Germany got a particularly good demonstration in November and December 2024. During two Dunkelflaute episodes, renewable production collapsed while demand remained high. Germany’s own Bundesnetzagentur says that almost the entire controllable power-plant fleet was brought into operation and that substantial electricity imports from neighbouring countries were required. The regulator concluded that Germany urgently needs additional controllable generation capacity for future Dunkelflauten.

That is basically the entire argument in one empirical example. When there is plenty of wind and sun, Germany can have extremely cheap electricity and sometimes negative wholesale prices. When the weather changes, the system suddenly needs the plants that supposedly became obsolete.

And the price swings are spectacular. Germany’s average day-ahead wholesale price in 2024 was about €79/MWh. During the November and December Dunkelflauten it exceeded €300/MWh for dozens of hours and reached approximately €936/MWh at the peak. The Bundesnetzagentur investigated whether those prices resulted from market manipulation and found no such explanation; the underlying condition was very low renewable production, high demand, extensive use of controllable thermal generation and limited remaining dispatchable capacity.

At the retail level Germany also remains one of Europe’s most expensive electricity markets. In the second half of 2025 a typical German household consuming 2,500–5,000 kWh paid €0.3869/kWh, compared with an EU average of €0.2896/kWh—about 34% more. Germany had the second-highest household electricity price in the EU after Ireland.

Those retail prices cannot honestly be attributed entirely to the nuclear phase-out or to renewables: taxes, levies, network costs, fuel prices and the consequences of the European gas crisis all matter. But neither can anyone point to Germany as evidence that a wind-and-solar-heavy system has somehow made firm generation economically irrelevant. Its own regulator is saying the opposite: when Dunkelflaute hits, Germany needs controllable generation and imports, and it says additional controllable capacity is urgently required.

What supplies that capacity today? Coal and gas remain substantial. Germany has zero domestic nuclear generation, yet it still burns coal and natural gas and participates in a European interconnected system containing large quantities of French and other nuclear generation.

So the actual German experiment is considerably less impressive than the slogan. Germany spent decades building an enormous renewable fleet while simultaneously destroying an existing fleet of firm low-carbon reactors. It succeeded in greatly increasing renewable generation and reducing coal use over the long run, but it did not abolish the requirement for firm generation. When wind and solar disappear together, Germany burns dispatchable fuels, imports electricity, draws on reserves and watches wholesale prices rise.

Which brings us back to the original question.

Once you accept that an electrical system requires firm energy during prolonged periods of inadequate intermittent generation, the menu becomes fairly obvious. Hydro and geothermal are excellent where geography permits them. Storage, transmission, demand response and renewable overbuilding all help. Countries fortunate enough to possess enormous reservoirs, geothermal resources or exceptionally strong interconnections can lean heavily on those advantages.

Those countries are not a universally reproducible model. A solution intended to work in most industrial countries has to survive winter demand, multi-day wind lulls, minimal solar production, droughts, transmission constraints and simultaneous weather patterns across neighbouring regions.

Under those conditions, you need some combination of renewables and firm generation. At present, for most countries without exceptional hydro or geothermal resources, large-scale firm generation means principally nuclear or combustion, with storage and interconnection reducing how much of it must run.

So yes: build wind and solar. Build batteries where they make economic sense. Build transmission. Use demand response. Exploit hydro and geothermal wherever available.

But after all of that, somebody still has to answer the boring engineering question: what produces electricity on the fifth cold, dark, windless day after the batteries have discharged?

“Baseload is a myth” does not answer it. “Batteries” does not answer it unless you specify the required energy capacity and how it is recharged. And Germany, of all countries, does not answer it: every serious Dunkelflaute demonstrates why it still maintains dispatchable fossil generation and depends on the wider European grid.

Two words: base load

And no you’re not solving it with a buffer (batteries or any kind of other energy storage for that matter)

cloudie78··on Raspberry Pi blocks changing RAM chips
I bought it, if I want to use a tape drive for my RAM I will do that.

The way they price their RPi’s - are we even surprised there’s now a market for cheap modified Pi’s with more RAM?

cloudie78··on Raspberry Pi 5 EEPROM update now blocks manual RAM upgrades
No it does not sound reasonable.

If they want to reduce the support burden they can use serial numbers to track what board has what ram - if they don’t match no support because it’s modified hardware.

cloudie78··on Google will buy half the electricity from one of Finland's nuclear power plants
Ah sorry, yes.

Let’s not fix that problem, get better at doing the thing that Europe was quite capable of doing (see France, Germany before they decided to let the green ideological extremists less the energy strategy) standardise a design and begin solving the energy problem.

Funny you should mention sovereignty, something a country enjoys when it has a source of energy of its own, especially when we can mine our own uranium right on the continent. Alas, we chose not to.

Instead we listen to the green imbeciles and now we’re buying our uranium and hydrocarbons from abroad.

And yet here we, burning coal because god forbid we run a few nuclear reactors right, green energy for everyone! An amazing success!
cloudie78··on Google will buy half the electricity from one of Finland's nuclear power plants
Ah yes let’s ignore shutting down nuclear reactors replacing them with coal power plants in the name of green energy which was so successful the country goes through a period every year called Dunkelflaute.

But yes let’s strawman into cars and heating instead.

Btw excess heat from the reactor can be and is used for central heating.

I think that’s a good thing, they could also build a nuclear reactor or two or three. Wouldn’t hurt.
cloudie78··on Growing proof that autonomous cars save lives
I’ll risk sounding crass to state the quiet part out loud:

Majority of car accidents outside of the occasional genuine freak accident are self-inflicted. Call it FAFO or Darwinism, whichever you prefer.

I’m saying that having done that myself once in the early days of holding a drivers licence and feeling heroic with my speed and a corner. I was lucky to walk away with minor bruises, mostly to my ego. And wallet.

That day I learned how a car behaves when it loses traction.

15 years later accident free, minus one person bumping the rear left side because they’d thought it would be a good idea to cross over into my lane over a solid line.

Having watched how autonomous driving is “developing” over the same span of time - I’m not convinced, the last decade was spent more on “trust me bro” targeting lawmakers than genuinely trying to have a breakthrough in the technology and we’ve hit a wall (no pun intended).

The correct answer to this problem is better driver education, and a higher bar for entry.

Lest we let the idiots take over and we as a society accept a lower standard.

Quite the contrary actually. I take issue with systems LARPing democracy.
cloudie78··on How Europe is killing makers and micro-entrepreneurs
Ah yes, let’s give the EU and its undemocratic system in which policy formation is heavily filtered through a relatively narrow professional political class, ordinary voters have weak or almost no direct control over major policy choices, dissent encounters administrative/economic punishment, and central institutions possess and use powerful financial means to discipline peripheral governments should have even more centralised power?

And no, just because voting for MEPs is bolted on there as a pressure valve doesn’t suddenly make it all okay when most of the real decisions happen behind closed doors and adherence to the passed laws, no matter how damaging is ensured through financial coercion.

Not a single person voted or agreed to this law, and yet here we are.
