There is simply NO safe level of fossil fuel use.
Not fossil hydrocarbons forever, of course, but synthetic kerosene might be a thing soon enough.
If someone is getting wiped from the mix because of renewables, it is coal and fuel, not nuclear.
About 85 percent of the total primary energy supply in Iceland is derived from domestically produced renewable energy sources. Use of abundant hydroelectric and geothermal power has made Iceland the world's largest electricity producer per capita.
What works for Iceland works in few other places to the same degree (New Zealand, Yellowstone, places with thin crust and feisty caldera's).
There are some interesting spots here but it's generally enough through the country to do it everywhere.
Munich gets quite a lot of it's energy from geothermal sources
Iceland has geothermal, which is amazing, but won't help central Europe.
This is important because wind season anti-correlates with PV season.
Plus, it's not like north-south power lines are beyond the wit of mankind. The US western interconnection includes both Canada and Mexico: https://en.wikipedia.org/wiki/File:NERC-map-en.svg
Not for the combination of [continent-wide, offshore, the Atlantic coast].
The Atlantic continental shelf isn't correlated with the Baltic.
Offshore Dunkelflaute is much shorter than on-shore.
> Storage in the required dimensions is an unsolved problem.
Also false. The required quantities even of batteries is comparable to electrification of road transport.
Also, independently of batteries, hydro plants come in two flavours that people often mix up: generation, and storage. Of these, only generation requires an associated upstream supply and watershed; storage can be done with a hole in the ground, of which there are plenty, and just the currently and soon-to-be closed coal mines in the EU can be converted to around 13 TWh of pumped storage: https://gfzpublic.gfz.de/rest/items/item_5038282_1/component...
And it's not like we can't dig more holes if we wanted to, we dig holes to get out rocks even though rocks are one of the cheapest things you can buy.
How do you transmit the power? Do the countries on the Atlantic even want wind power, set up the transmission lines, and pay for it?
> Offshore Dunkelflaute is much shorter than on-shore.
That reduces the storage requirements a bit, but there is not nearly enough offshore. And offshore is expensive. That's why it's getting harder to find investors.
> The required quantities even of batteries is comparable to electrification of road transport.
That doesn't prove it's possible, but makes it even harder to get the required quantities.
> hydro plants come in two flavours that people often mix up: generation, and storage
Hydro requires the right geography. Is there any potential for hydro left in central Europe?
> EU can be converted to around 13 TWh of pumped storage
That would be a good amount of storage. But has this ever been tried? I would guess that's quite dangerous: https://www.youtube.com/watch?v=LseK5gp66u8
The usual way.
> Do the countries on the Atlantic even want wind power, set up the transmission lines, and pay for it?
They can sell the power, you know. This already happens.
> That reduces the storage requirements a bit, but there is not nearly enough offshore.
It more than covers it.
Even a Dunkelflaute period is reduced, not zero, output. Those seas are huge, and the normal wind there is fast; even on a continental-shelf-spanning Dunkelflaute (much rarer than "just Germany and Poland"), the capacity in those waters *even with that reduction* is more than EU demand just by itself, which in practice means "not building as much as possible".
> And offshore is expensive. That's why it's getting harder to find investors.
Compared to onshore wind. But even offshore wind is cheaper than new-build nuclear, coal, and has strong overlap with new CCGT.
Even then, it's not hard to find investors: the US went as far as banning it because the investors were actually happy to invest.
The limitation on investors right now is that we're transitioning faster than any previous energy transition before, while also having other things to also invest in. It's like how big tech in the US is running out of people to get money from to spend on data centres, the limit isn't actually building them, it's how fast they're getting built when your answer to "how many would you like to order?" is "yes".
> That doesn't prove it's possible, but makes it even harder to get the required quantities.
The fact that EVs are for sale, however, does.
> Hydro requires the right geography. Is there any potential for hydro left in central Europe?
I thought you might say something like that, *which is why I literally wrote what I wrote*:
people often mix up: generation, and storage. Of these, only generation requires an associated upstream supply and watershed; storage can be done with a hole in the ground, of which there are plenty
Also, I already saw all of Tom Scott's videos when they were new. As per the document:
Finally, the realisable potential includes projects that are not only technically and economically feasible but also aligned with regulatory, environmental, social and implementation timelines, facilitating their implementation within short to medium time frame.No, it's not. Decommissioned nuclear plant infrastructure used as massive battery storage.

The following table shows that in total 2264 installations have been identified in the EU ETS to be power plants, which have reported emissions in at least one year since 2005. The fuel of 1440 power plants have been identified. Of this there are 124 lignite power plants, 284 hard coal power plants and 2 power plants using blast furnace gas. There are 57 power plants using oil products. The majority of the plants uses natural gas (858 plants). About 824 plants have not been matched to a fuel yet.
We're building the factories to make them as fast as we can find investors with money to spend on them, because they're already cheaper than fossil fuels which are themselves cheaper than nuclear.
Oh come on.
I don't have a clue either. Don't ask for my vote on how to power a country. Take my taxes and use them to listen to experts
Why is it a good thing that everyone and their brother seeks to apply state violence to micromanage what should be a fairly arcane technical issue?
>We can't let decisions like these be taken by unelected technocrats alone.
Do you feel the same way about topics where your opinion differs substantially from the local majority?
Edit: I don’t understand how you get from „political decision“ to „state violence“. Politics are at play at all levels of civilization where actors have different goals, from your dinner table and your company Slack to democratic institutions.
I almost hesitate to ask, do you think that is the centralised or decentralised option?
And, more directly, that is a bad theory. The billionaires will make money either way. It doesn't make a lot of difference to them as a class. They'll have an inclination to the cheaper form of energy because more energy -> more economy -> more money for them.
The venn diagram between people who act like renewables are "freeing" (which make no mistake, they absolutely could be) and the people who advocate nonstop for government management of how they are deployed is too close to a circle for me to take such commentary seriously.
>One of these options makes it much easier for the billionaire class to continue extracting money out of the people.
Ah, yes, billionares. Famous for not getting a cut when I buy a plug in solar panel from my preferred e-commerce site or big box store. /s
The billionares have their money in everything. They get a cut of everything. You're just changing who gets the cut. And even if no billionaire is getting a cut, a publicly traded/owned investment bank or other corporate interest that would replace them is not really any less evil.
>: I don’t understand how you get from „political decision“ to „state violence“. Politics are at play at all levels of civilization where actors have different goals,
By not gaslighting myself into thinking politics is anything other than the process of deciding where, when and how state violence is applied.
What backs up all those decisions other than credible threat of violence?
Where did the person you are replying to even hint at that? I think this may be your own prejudice spilling out here.
> The billionares have their money in everything. They get a cut of everything. You're just changing who gets the cut.
Oh ok, I guess let's just accept this as is forever. Any attempt to try to improve this situation is futile and stupid (for example, as said, making it more difficult for them)
>What backs up all those decisions other than credible threat of violence?
I don't know, do you only act in fear of the threat of violence from the state? In democracies politicians are legitimized by their voters, what you are describing sounds more like an autocracy.
If you can spend a Dollar only once, you might end up with renewables. People can be economically motivated too. No reason to draw politics in an already heated discussion.
I mentioned all of this in my message. What was unclear about it or did you perhaps not read past the first sentence?
