It doesn't in any way solve the increasing electricity need in the future though, even assuming it would be fast and cheap to fix (it's not). That said, the coalition also wants to improve the transmission lines.

Fix increasing electricity need

About as easy as fixing world peace.

Also, a lot of the new energy needs comes from "green steel", which would give massive reduction in the green house gas production required to produce steel.

But for that to make sense we need lots of clean energy.

You make a number bad claims here. The effect of not having enough planable energy production is that prices go up and that the energy industry starts gradually worse power plants. So you have the oil powered plants in the south, spewing out CO2. The reason why this "works" is because a number of countries in the vicinity have large needs for energy in the aftermath of having shut down their planable energy productio…

> Actually this year many countries were pushing energy to France were most nuclear plants were not operational for maintanance and heat.

This is not in any way in contradiction to what I'm saying. In fact: this supports my case. Because the amount of nuclear power generation is down, prices surge. This is my point. Your point was the opposite, remember? More nuclar power will increase prices?

> Are you saying Vattenfall did not shut down ringhals because they said they are not commercially viable? You are directly contradicting their own words (In October 2015, Vattenfall decided to close down Ringhals 1 by 2020 and Ringhals 2 by 2019 due to their declining profitability, instead of, as previously announced, around 2025.[16][5] from https://en.m.wikipedia.org/wiki/Ringhals_Nuclear_Power_Plant)

If you read what I said, I said that nuclear power was artifically made inviable because of extra charges and taxes. It was perfectly viable and economically sound before these.

> You mean they could not find investors on the open market because they deemed it too risky with questionable returns, without government guarantees. Is that not how the free market is supposed to operate?

Right, because the political climate is such in Sweden that there is risk in investing in this, there won't be any interest in investing in this area. I said this as well. A free market would work here but we don't have one. The reason for government guarantees at this point is as an offset to the perceived political risk. A nuclear powerplant is a 20-40 year investment and if there's a very large risk that a populist government were to negate this in 5-10 years, then noone wants to invest in it. This is where we are.

> HVDC has 3% power loss over 1000km HVAC has 6%, losses are not the problem. From https://en.m.wikipedia.org/wiki/High-voltage_direct_current You are correct capacity of those lines is a problem though, maybe some investments are in order?

Losses are part of the problem, yes more investment here is needed but this is not the biggest problem. Another commenter here mentioned the fact that because there isn't enough capacity to _receive_ the transfers, they can't be made. This is to do with the lack of inertial reserve(?) (svängmassa) after having switched off so many large powerplants over the years.

> What are the bad environmental consequences? Also offshore wind has a capacity factor of 60% that is similar to nuclear.

I'm going to have to call that 60% number.

The consequences are visual (i.e.: ugly), noice, birds as well as the fact that they are niether degradable nor recyclable because of the types of material needed. Do note, though, that I am in no way anti wind power.

> That just points to a huge market opportunity. If the wind turbines have to pay "huge" amounts when the wind is high, I just need to store that energy and make twice the money.

Right. So you need batteries, we need improved tech in that department, someone has to make them and this requires a number of let's call them "troublesome materials." "I just need to store that energy" is as reasonable a thought as: we just need to feed them, about starving people. That just-word there is quite powerful.

> Funny, usually it's the nuclear proponents saying it's all straight forward and the opponents are just ideologically motivated.

Well I am not one of them. You started out with the big I-word here and it is my honest opinion that it is better served the other way around, and for these reasons: a number of the problems we have in sweden with the power (and heat) generation is to do with the fact that we did turn away from nuclear power. The same can be said about Germany and both for the same reason: ideologically (or at least populistically) driven policies.

I'm not in love with nuclear power in the slightest. But it is one of the least bad solutions so we must really put away ideologically driven dreams and deal with reality. This is in regards to Sweden's current nuclear technology, which is to say, really old tech as it's basically from the 60:ies. Quite a lot has happend since and saying no to that without understanding the complexities and nuances to this and because Someone Puleaze think of the ch... environment? That's just poor judgement.

Renewables don't give you baseload power. So renewables + nuclear is a good balance.

Everyone forgets about Hydro. Not only can it be a great source of baseload power, but it can also be turned on and off very rapidly to provide peeking capacity. Pairs very nicely with Wind and Solar if your country has the right terrain for it (which Sweden does, hydro provides 45% of their current capacity).

Correction: Northern Sweden has the right terrain for it. And there's a limit to how much hydro that can be built there, and it's close to built out already.

Funnily the rhetoric of nuclear proponents is always exclusively aimed against renewables not fossil fuels. They know if not for ideological/political reasons/influence no nuclear plants will be build because it is just too expensive. If I can build double (now, the difference is rapidly increasing) the capacity using wind or solar why should I build nuclear? People who propose to do otherwise are the ones who are in…

When you think a large group proposing something is collectively insane, it usually means you simply don't understand their argument. Surely, you know that wind power has had a lot of trouble expanding in Sweden due to huge opposition from every community against building wind turbines on their land. Everyone likes the idea of wind power until they try to build a huge turbine on their backyard. Sun power, in Sweden,…

We have a large scale war in Europe now with Russia threatening with nukes. We have attacks by unknown actor that destroyed gas pipelines.

From this one can see how the idea that somebody will bomb out a nuclear power station somewhere in Europe gets non-trivial probability.

So nuclear power really cannot be safe when this planet allows crazy guys to gain enough power.

As for coal then consider that an electric car that uses electricity from a modern coal plant with over 40% efficiency generates less CO2 than a gasoline or diesel car.

So rather than building nuclear power, the states should invest to upgrade older coal power plants from their 30-35% efficiency to 40-45% and quickly phase out petrol cars while expanding on renewables.

> For example, in order to address this there is a oil power plant operating basically 24/7 and does so very profitably even with high oil prices. This is not why the oil plant exists, it is an emergency plant. If it is running 24/7 then it does so because the oil plant is profitable. Not out of necessity.

> If it is running 24/7 then it does so because the oil plant is profitable. Not out of necessity. This feels like your splitting hairs because the root cause is ultimately the same: if it wasn’t necessary then it wouldn’t be profitable.

Not really. It is part of the Swedish capacity reserve during winters, i.e. the national grid operator pays it to be in standby to ensure the reliability of the grid.

Its current operations are because even though it is an expensive oil plant it is profitable to run it for export on the European market.

A Swedish professor in energy systems looked closer at the electricity export compared to the operation of the plant, and out of hundreds of hours operated during this year something like 1-5 hours were not matched by equal or more electricity being exported than it produced.

In Swedish, sadly without subtitles, but an amazing overview of the Swedish electrical system.

Electricity should cost peanuts and that should the goal of every sane government.

Electricity prices should include all the negative externalities such as pollution, carbon dioxide, destruction of habitats, geopolitical dependence on Russia etc.

Electricity, like an increasing bunch of other things, is part of the infrastructure. The amount and different levels of infrastructure pretty much define "civilization", do away with infrastructure and your civilization is done for. Which also means that the way a civilization treats its infrastructure tells you a lot about this civilization.

If you look at Europe, they messed things up big time. Firstly, running infrastructure like a company will never work, by design. So this whole privatization is a big sham to begin with. It is made worse by the fact that there cannot be a market as such, so they defined rules to create a market. Humans being exactly that are too stupid to include the human factor into rules, so this whole "market" is completely and utterly broken, and pretty much a money transfer machinery (like so many others) from the bottom to the top.

Which means in the end, while I can understand your idea/approach, but it will not solve the problem with energy cost.

> runs into all the usual issues with planned economies. Oh, and the war in Ukraine does not show the glaring weakness of 'Unplanned economy' and just choosing the cheapest supplier? Subsidies and incentives do not a planned economy make. Folks in the west seem to have taken the failure of hofhly corrupt planning system of USSR as an indication that they dont need to do any thinking or planning at all.

The point of subsidies and incentives is to plan an economy. There are many different levels of panned economies. With say US food subsides and tariffs as a less extreme than Maoist China or the USSR, but they still have huge and well known problems. Messing with Food production has resulted in inefficiency, waste, pollution, corruption, etc but also overconsumption with it’s extremely negative health impacts. It’s j…

I think you live on a different planet - on this one our market is selling bloody dictators weapons and parts that they will use against us.

Will they also build a new nuclear waste repository then or are they just going to dump the radioactive waste into the Baltic Sea? Besides: Are they going to buy Uranium from Russia as the US are doing for their reactors?

> Besides: Are they going to buy Uranium from Russia as the US are doing for their reactors?

Sweden has been anti-nuclear for several decades, and one of the laws that has been passed is to forbid Uranium extraction, even though Sweden has quite a bit in its soil.

So if this development is any sign, maybe they'll do away with that silly law as well and make it so Sweden doesn't have to buy it from someone else?

Also, Russia isn't the largest exporter of Uranium.

Typical right-wing reactionary environmental policy. When you do not have any climate-related politics to bring to the table, all you do is shout "nuclear" at the top of your lungs and tote it as the solution to everything climate. > Much of the resistance towards 100% Renewable Energy (RE) systems in the literature seems to come from the a-priori assumption that an energy system based on solar and wind is impossible…

Solar isn't economically feasible in Sweden. Too far north, too much snow, and during winter it's dark for months. Might work better in the far south, but not good enough.

Sweden isn't exporting electricity for free. The money is there - it just needs to be redistributed from companies to the people.

Especially since the Swedish power company - Vattenfall, is 100% owned by the Swedish state.

You mean Svenska Kraftnät (SVK) instead of Vattenfall, they're the ones making money from electricity distribution. Vattenfall is an electricity producer, it's not responsible for this kind of distribution across borders. It is responsible for some distribution within Sweden (regionnät), but there it is not the only player. SVK on the other hand is 100% owned by the state.
