Following nuclear power exit, German power CO2 emissions are reduced by 24% (2023-04-16 to 2024-03-15). Renewable energy production increased significantly, coal energy production is down 29% (brown)/47% (black), gas is down 5%.

@juliank what? Is that because they're buying a lot more renewable energy from other countries?

@necrophcodr imported 20.6 TWh more than we exported. 4% of imports were fossil/nuclear.

So ... maybe?

@juliank I don't know the source of those numbers, but if "less energy produced because more is imported" is included in "renewable going up", that's definitely not very useful of a measure, is all im saying.

@necrophcodr @juliank Denmark seems to have plenty of wind and solar, so if they're selling it seems good; I mean it's not much different than importing gas say; either way it's import.
(The UK is down to ~1% coal, which is due to switch off soon - it's a bit easier for us because we ran out of good coal to mine, so we'd have to import that anyway; we do have nukes and have some being built)

https://app.electricitymaps.com does have some historic data (switch at bottom right to get older stuff)

@penguin42 @juliank oh I'm not saying it's objecticely a bad thing. More energy being renewable is a good thing in my book, no matter if it's imported or "locally sourced". but meddling with numbers to reach some criteria just doesn't sit quite right with me.

@necrophcodr @juliank If the consumption emissions are down then I think it's OK either way; if you're just recording production emissions then I agree.

@penguin42 @juliank presentation matters a lot, especially in a world today where there's an increasingly abundance of data. not all of it is good, and a lot of it is very hard to reach any conclusions from, simply due to bad presentations.
There's obviously a lot more to it, and I won't claim to be a data scientists just because I work in a data science department. All I know is that it is very important to be excruciatingly clear about what the data actually is.

@necrophcodr @juliank Right; that's why I like sites like electricitymaps and https://grid.iamkate.com where I can see the data.

@penguin42 @necrophcodr on electricity map you can see a reduction in coal power consumption by 29% from 2022 to 2023 fwiw.

But consumption doesn't really matter for the story. They said turning off the nuclear plants is a bad idea as we will burn more coal, and we didn't.

@necrophcodr the source is the study from Greenpeace and Green Planet Energy they just published.

So yeah I mean kind of biased but it also kind of makes sense.

Working EU market to redistribute renewable energy is a good sign.
