Wind in practice. There's only few hours of sunlight in the winter during the day. There has been a surge of electric boiler buildup by district heating companies in the last few years to exploit the periods of high wind and resulting

Several cities in Finland have water based thermal batteries already, connected to local district heating networks. They have been previously used to store energy from existing combined heat and power plants, but now that wind power build u

You can also build the datacenters somewhere where there is plenty of carbon free energy available. Google has just recently bought two plots in Northern Finland, near some serious grid connections, and they're not the only one with pl

I don't think Nordics will be needing much batteries, Norway and Sweden have so much hydropower that can absorb fluctuations in the power production and usage. But there still will be a lot installed alongside new renewable sites, you

Finnish energy company ST1 tried to make a deep heat district heating plant and drilled few over 6km deep wells. They wanted to connect the wells at the bottom but failed to get enough water flowing between wells for profitable operation.

TIL that networkd has built-in DHCP server. I don't think that this matters here, using networkd for client configuration shouldn't prevent using something else for server.

Entire police force of Finland (~7300) is only about fifth of NYPD (~33000 officers), but they have over 10 times more drones, more than 330. https://poliisi.fi/en/unmanned-aerial-vehicles

At least here in northern Finland you could already do that even with staff present. Everyone goes in with backpacks or bags and with self service there's no way to actually monitor if all the books were properly checked out.

It's not uncommon in Nordics to have satellite libraries with mainly self service hours where there's no staff present but you need to swipe / scan your library card to get in.

Empty threats, Nordic unions would just block all the imports.

Consumers in Finland (and as far as I know, in other Nordics too) can get Nordpool spot priced electricity contracts, doesn't really get truly negative since you need to pay margin, taxes and transfer anyway.

Last year, 2000 MW of wind power was built, at the end of the year total power was 5200 MW. Olkiluoto 3 nuclear reactor was brought online, 1600MW. Solar power nearly doubled, from 358 MW to 606 MW. So far this year 500MW of wind power and

I live above latitude 65 degrees so auroras are quite common. Few years ago I had to deliberately go out and seek location without light pollution and watch auroras because I wasn't sure anymore if I had actually seen them live. Now I

Is this some kind of Russian media operation? Few hours old substack account with no proof that it is even written by Seymour Hersh, tweeted by both Snowden and Matt Taibbi.

The bubble that knows about this ban so far is relatively small. Will it reach the advertisers at all? Edit: my bubble was too limited.

Finland is currently transitioning to a system where employer must compensate for the time employee is restricted, and all previously agreed contracts must be either terminated before this year ends or employee will get paid for the time ac

We are going to have lot of intermittent energy production with wind and solar energy. This is a cheap way to convert that to continuous heat for industrial processes, instead of storing it as electricity in expensive batteries.

Finland is having a boom, 70% increase in built wind power last year and 70% this year so far, and I checked the projects completed or completing this year. Most are Vestas and Nordex, some GE, and few outliers (Siemens, Eventus, Cypress on

No one is truly debating this anymore in Finland. People who have lived in ceded Karelia have mostly died.

Article says that powerplants in Finland have reduced power output, but as far as I can determine, that's just not true at all. Olkiluoto 1 had extra maintenance break recently because of faulty fuel assembly, but is now on full power

Last 10 gigawatts of shut down reactors were all finished in 80's and probably had half of their design age left, all the really old were shut down already in nineties.

They wouldn't have shut down all the working plants. Not that it matters much, wouldn't have been enough.

At least here billing is based on amount of energy extracted, so both volume and temperature difference are metered.

Local district heating utility here in Oulu, Finland has 190000 m^3 underground heat storage capable of storing 8 GWh of heat with 40 MW of input/output capacity.
