Electric Wrigglies posted:just imagine if Germany utilised its wealth, technical and industrial base to install low carbon generation three decades ago, might have g/kwhr numbers approaching those of anti-green French. Saying they are doing better with wind and solar given their location and circumstances is missing the wood (pellets heh) for the trees. And a lot of the hate on Germany is not just because they are all NIMBY on nuclear now, it is because they are also generally the preachiest of EU nations on what other nations should do up to and including opposing counting nuclear as the low carbon generation that it is (mainly because one of the big arguments against nuclear is that it is too expensive and doesn't work all the while France has been running reasonably economical-price, low-carbon power since the '70's for the majority of their grid). Yes that sure would have been amazing, but we didn't due to having lovely coal and gas industry controlled conservatives in power for decades, some of which are close personal friends to putin. Doesn't change the fact that renewable production increases have led to significant reductions in emissions, and continue to do so while other countries in the EU and outside are either not doing anything or are increasing theirs. The energy policy of Germany has been poo poo awful, that has nothing to do with replacing fossile and fissile sources with renewables tjo, but with awful, awful political decisions. The current developments are still good tho. GABA ghoul posted:Seeing how almost every commercial and residential building around me is now hastily slapping PV modules on their roof makes me wonder how much that affects official power consumption statistics. I assume to grid operators the installation of the modules would seem like a simple decrease in demand from factories and office buildings and they don't have access to anything more detailed than what capacity was installed. Yeah it usually just gets registered at the Marktstammdatenregister in case of small scale balcony or rooftop PV up to 25 kWp, after that you need to enable grid shut-off control which includes a meter that provides 15 minute data to the grid operator. So those definitely get counted, below that the electricity just kinda goes into the grid and yes, just gets counted as reduced consumption. Overall since everything is registered in a central register and grid operators therefore know the rough production capacity at any time and location, they can approximate how much is produced depending on weather data and consumption profiles.

QuarkJets posted:Carbon emissions would be even lower if the nuclear power hadn't been turned off, that chart does not dispute this fact No, not as much as you imply. A lot of the plants would have been turned off anyway due to old age or would be turning off during the next few years. Also, the biggest and oldest pro-nuclear organisation in Germany (CSU) specifically said last spring that if we let it the free market freely decide to buy the old isar2 plant then that will solve climate change forever. And that we should encourage the free market by blocking the ban on fossil cars, and refusing to take any other action. Which absolutely implies that the emissions in fall 2022 were low enough to solve climate change, as it is defined by pro-nuclear politicians. So, your graph will never be enough to convince any German who paid attention to politics then to become pro-nuclear.

Raenir Salazar posted:Isn't that a problem? Mostly indirectly. Germany has essentially polarized on being pro/anti Green as a focus issue. And being "pro-nuclear" has become a core callout for the anti-Green side. So, if someone complains about the Atomausstieg in Germany this month, literally everybody understands that they actually mean that they oppose the planned reduction in subsidies for diesel fuel. And longer term, the "pro-nuclear" side is also the pro-austerity side, so they oppose government funding for new plants even harder then the actual greens. We can actually see that with fusion funding.

In 2023, the wind and solar share of German electricity production reached its highest percentage of all time. This was primarily due to a sluggish economy using less energy generally, increased energy imports, and the early shuttering of the last of the German nuclear reactors. Success!

Nope, renewable produced energy has reached the highest amount 2023 of all time. This is also the highest percentage, so you're half right. Also yes, increased imports are a great success story since it means co2 pricing on cheap coal has worked, which was a historic source of german electricity exports. Coal and fossile sources have reduced their contribution on production by 24% in fact due to not being competitive more and more often. This was replaced by low emission renewable or nuclear imports and increased inland renewables, of which the changing european grid has more and more available.

DTurtle posted:I will never understand the hostility to energy trade within the EU + periphery in this thread. Because the EU is not a monolithic block where countries share their resources and funding as within a country. The EU energy market and its pricing system has been something of a shitshow where countries with historically low energy prices get uncomfortable price fluctuations and countries have used imports as a substitute for expanding their own capacity leading to a lack of overall capacity.

Because we have now seen twice within 5 years that in a crisis situation it's every country for themselves, with everyone passing (often actually illegal by EU law, but no-one cared) special laws that gently caress over their neighbours a lot just to help themselves a little. And energy is not just an economic thing, here in the frozen north we are going to start loving dying if the power is off for too long. So there must be sufficient capacity to keep the heating on, and it has to come from a place that we can actually trust won't cut it off to help themselves. Which means from within our own borders.

In renewable news:quote:The world’s first commercial-scale floating wind farm, the 30 MW Hywind Scotland, officially entered the operations and maintenance (O&M) phase in October 2017. After a little over six years of operation, the wind farm’s Siemens Gamesa wind turbines are now due for some major maintenance work. That's not necessarily a knock against it, 6 years is decent enough for floating in the ocean I suppose, but we'll see how much time and money it'll end up costing.

Zudgemud posted:No, it's not a binary choice the solution is to build international transmission AND much more generation capacity. Not sure what you are saying, but a country can deal with the intermittency issue of a growing renewable production either by - integration into a larger, geographically spread out renewables grid and lose self-sufficiency or it can - try to remain self-sufficient and keep its renewable capacity isolated and rely on fossil fuels to solve intermittency You can't do both at the same time. One of them allows a much faster phase out of fossil fuels use and a chance to reach the 2040 & 2050 emission goals and the other does not. Indulging in nationalism, paranoia and isolation are going to cook us alive.

So basically Germany is increasing renewables while offloading their baseload needs to French nuclear plants thanks to pan-European grid? While best would of course be that Germany would build nuclear too, I think this is the best solution to lovely situation. So yeah, I'd say good news.

In my opinion autarky is rarely sound policy, it's good to have something in case of emergencies; i.e see production of vaccines. But market forces make it so that energy service and pricing will be better/lower for the consumer if the market is larger with more competition; so naturally countries are going to mostly buy energy where it's cheaper than to spend the high upfront costs on more expensive baseload. In an ideal world there would be a little more sensible central planning to ensure that there's enough baseload (i.e nuclear) being spun up to cover the needs of the entire block while still letting market forces deliver that energy to where its most economical.

Speaking of nuclear baseline. In 2023 Germany produced 9% less electricity and became a net importer even when electricity consumption decreased by 5%. Wondering what will happen when the demand again rises. More coal or gas or both?

mobby_6kl posted:https://www.thehindu.com/sci-tech/science/npcil-commission-nuclear-power-reactor-every-year-pathak-interview/article67751083.ece Interesting. I wonder if the capacity to build the 200 MWe units is separate from the 700 MWe units in term of foundries, etc. I can understand India not wanting to waste a nuclear amenable site on a smaller unit but for nations with smaller grids, a larger (like 6) number of smaller units might be the better way to go when you consider refueling cycles, etc. For eg, if Western Australia was to build four to six of them, it would be basically exactly that much gas fired generation being turned off. Doesn't make any sense if that would displace 700 MW units being built in India though. In closer to me solar news, have a proposal for a 25 MW solar plant, ~US$28M capex, ~18 months build and would save about 20 kt of carbon a year and pay back in about five years. On the grid so save a bit on not needing batteries but also no opportunity for powershifting the excess solar generation during the peak of the day.

in a well actually posted:Four 200 mw reactors cost a lot more than one 700 mw reactor; thanks, square-cube law. That's not really the case, for exactly the same square-cube law you mention. A lot of the safety systems required, and required to be highly redundant and nuclear specific, fall away as the square dominates the cube.
