Are there any plans to build an infrastructure to connect both networks? It seems like a great idea in the current situation

A political issue with this is that Northern Norway has been exempt from the 25% VAT as one of many measures to make living in Northern Norway more attractive. Until now the cost of power in both north and south has been pretty much the same, meaning people in power zone NO4 have paid about the same price for power, but not the VAT. But now that the price has gone up by such an enormous amount in the south, connectin…

This is a great post. This part: > and this part: >

Ouch! Is this not enough to push for interconnect? Or will the electricity price increases prevent such a change?

Alternatively, why hasn't more heavy industry been built in NO4 zone? Or is it not possible due to winter weather?

I also heard that in Norway, a high percentage of electricty is generated from gravity (water dams). That would make aluminium production ideal. I have heard this is one reason why Iceland, with excelent geothermal energy sources, is also a major aluminium producer.

Are you telling me that Sweden, a country of 10 million people, which has wildly differing electricity prices within that same small country¹, could simply use copper conductors to solve this problem, but chooses not to for political reasons ? 1. https://news.ycombinator.com/item?id=32618798

Yup. Might not even be wrong to have made this choice, I can't tell — economics (which is an important part of politics) is outside my domain.

What possible political reasons might those be?

That gasoline wouldn’t be an energy source, it’d be an extremely crappy battery. Far better to just send the power via grid to an EV @95% then toss 60% or more of it to make a gallon of gas

it’s a more practical solution for right now though. we can’t expect the world to switch its entire infrastructure overnight, or even quickly. yes, the rich nations might get a head start, but they represent such a small fraction of emissions.

I really hate this "overnight" argument, because it's used to avoid starting. Nobody claims that we can switch to EVs over night. We could however switch to only producing EVs in like two to five years and fifteen to twenty years later almost all cars could be EVs. That's plenty of time to fortify the electric grid for the extra demand and build adequate numbers of charging points for people without garages.

>yes, the rich nations might get a head start, but they represent such a small fraction of emissions. Not really for automotive emissions. The US alone accounts for almost half the world's road CO2 emissions.

and automotive emissions account for ~10% of all CO2 emissions. 20% if you want to include all transport (e.g. sea shipping, planes, etc.) there’s been a lot of media attention on how individuals need to make an effort to beat climate change, but the reality is that industry is the only sector able to make a meaningful impact.

10% is huge though.

Current spot price in northern Norway is €10.16/MWh, while it is €745.08/MWh in southern Norway (73x the price), largely due to limitations in transport networks between the electricity zones. The price in the northern zone is so low that some hydro plants have stopped producing electricity as they would be losing money at the current price level. https://www.skandiaenergi.no/dagens-spotpriser/ Electricity Maps has a…

Ive tried to explain this issue to EVs fanatics, but nobody listens. Anytime you mention energy transmision issues - you get total backlash. We wasted EU money on pointless stuff while we could have upgraded our transit cables etc.

Multiple solutions are already known, some better some worse. It's politics and economics that's in the way, and even then the world is changing.

I'm honestly curious about a thing, that might sound not so in-topic, but that is, actually: HN is supposed to be a technically sound community, however when someone post about some trendy neoliberals-related topics a certain part of the community instead of remain technical start to be partisan, sometimes at fanatic levels. The in-topic part is for instance about p.v.: if you think a global electricity grid as a sol…

you don't need global. just connecting the eu together has significantly strengthened their grid.

Top utilization of solar was approximately 25% of the installed base today At the same time, 49% of nuclear in France is being used today and 62% of nuclear in the UK So, it's "bad" but not everything is used 100% all the time

The thing is, on a perfect day, Germany has enough solar capacity to fulfill almost all of its electricity needs. But that perfect day is rare, largely because of Germany’s climate. So you have a situation where you have to essentially install over 100% of your needs in solar. You’re overspending for suboptimum results.

yes you overbuild, but solar is still one of the cheapest girls is electricity even when you consider the necessary overbuilding.

We don't see large tidal power installations because they are not every economical so far. In theory there's a lot of energy to be won, but the salt water causes corrosion issues, and maintenance gets expensive quickly

This is a very good post. I never before considered the issue of corrosion. To that point, does this also affect offshore wind power generation (turbines)? I guess the difference will be: the turbine is not underwater!

offshore wind is much less effected because all the complicated parts are 100 feet up, and much easier to partially seal.

Britain is the best position country in Europe for wind and tidal power. There was a project to pay down cable to import reliable, cheap 24/7 power from Iceland and hobernment said 'nah'. They also cancelled a 340 MW tidal project

Is wind power even worth the investment? From disposal issues to wind turbines killing birds and bird habitats to sheer unreliability, wind seems to have a ton of issues.

wind mills kill way fewer birds than mining does. wind has a few incredibly minor issues, but so does everything, and wind is green and cost effective.
