Croatia wants to turn superhot underground lake into 16MW power plant

Though its average throughput is likely to be 10MW due to the non-optimal wind.
Typical onshore wind turbines are ~1.5MW

> New offshore wind projects have capacity factors of 40%-50%, as larger turbines and other technology improvements are helping to make the most of available wind resources. https://www.iea.org/reports/offshore-wind-outlook-2019
Below, a diagram shows current numbers as approximately 30%-55% for offshore and 25%-45% for onshore wind.
Is it mostly because this is Croatia? If so then why cant we have similar cheaper construction across rest of the Europe? I feel like construction projects have their costs vastly inflated the further you go to the western side.

Germany is only worse them in emissions because they temporarily boosted coal usage last winter to ease gas supply constraints. All of that added coal capacity is now back offline, and it's looking like they should be able to keep it offline this winter, but we'll have to see.
That and they closed nuclear power plants
Coal usage has continued to fall despite the closure of the nuclear power plants (though obviously it'd fall even faster if they had kept them open).
So nuclear's definitely more than zero that this map shows, but it's technically imported from Slovenia, though not really. It's one of those edge cases you can't fit neatly on a map.
There's also a graph for the origin of electricity that's available in the 24 hour view that shows different origin countries mixed in with different fuel sources.
Except it's absolutely not. As in the source they use (ENTSO-E) absolutely has no notion of energy sources. I can also see that the other source they've listed for Croatia is offline, and according to Wayback that been the case for at least a year. In conclusion, carbon intensity per 24h might as well be pulled out of their asses because they, and I can't stress this enough, don't have that data.
Meanwhile, the website of the nuclear power plant, which is again co-owned by Croatian state-owned electricity company, tells me it's responsible for 16% of Croatia's annual electricity usage, while this website tells me it's zero. Gee, I wonder which of the two is more of an authoritative source.
Seriously, stop trying to correct someone that's local to the area and knows a bit more about the situation than what you've learned in the past 20 min via your shitty global web project that has to take a shit ton of shortcuts in order not to be empty.

It's alarming to see how much this diverges from the numbers from Statistica.
EDIT: I misunderstood the UI. If I click "6 years", it shows 301 for 2022. Also, it claims 0 consumption of nuclear, which must be wrong given the information about the nuclear plant above.
Can anyone see where Scotland sits? Our live snapshot current shows 7 gCO₂/kWh:
The figures don't seem to work out for me there. If we assume 10k homes (so just one ten thousand) that's 1.6kW per home, which isn't much (in most countries a single socket can supply 3kW)
Yes, when I'm running my toaster or electric kettle or electric heater, my home may consume more, but I don't run those most of the time. There are even times when my home has almost no instantaneous electricity consumption.

With an average household size of 3.2 that's realistic.
Though imho it's a bit much. Pre-heatpump, our two person house drew less, even though I charge a PHEV. Maybe the figure includes industrial use?
Less industrialized than other parts of EU is surely a factor too.
I'm really curious what brought you to that conclusion.
Having little to no insight or direct experience. I cannot tell you how unbearable Istria and Dalamatia coasts can get in the Summer months without AC. And I've lived in Zagreb not far from the Slovenian border when we couldn't afford to turn on the radiator on for more then a few hours and it f'ing sucked. It made living in Germany almost comfortable by comparison--I lived near the French border and only had kachelofen to heat the home.
Croatian climate is incredibly diverse, its much like Californian climate in that respect; it has lots of islands where you may get away without AC or Heating, but that doesn't encompass the mainland. For such a tiny country it has a lot of diversity in terms of climate and culture for that matter.
I don't think this is the case in any modern household, as long as there is at least one device with a transformer (i.e. a "charger") plugged in. Of course, you can theoretically turn off all electricity, e.g. when going on holidays -- but most people don't do that, especially if they have any kind of smart devices or even an alarm system active.
Total energy contained in the mantle is about 12 million million million million million Joules. 12 x 10^30 J.
If every person on Earth extracted a million watts every day, it would still take millions of years to deplete that heat.
If you were wondering, the point at which adding more wind turbines slows the others by more than it generates (saturation wind power potential) is estimated to be about between 80 and 380 TW, depending on if you only include land but not Antarctica, all surface area including oceans and the jet streams.[1]
Total global electricity generation is currently about 3TW, and all energy is about 20TW, so there's quite some headroom there!
Also illustrates the massive civilisational scale undertaking to electrify the world: rebuild electrical capacity maybe 5 times over.
Even if one were to accept the premise that geothermal energy production would ultimately stop our magnetic field (which I don't), "the long run" here is a very, very, very long time from now.

You're right. Everything is hopeless and we should do nothing.
That said, a Longtermist startup focused on wrapping blankets around volcanos/geozits to save our atmosphere would certainly bring some levity to the news.
