2023 wird ein weltweiter #Photovoltaikzubau von 392GW erwartet. Das ist die Leistung von 1 GW oder einem #Atomkraftwerk PRO TAG! Derzeit werden nicht mal 10 Atomkraftwerke PRO JAHR gebaut. Was soll die permanente Diskussion über das bisschen #Kernenergie?https://www.pv-magazine.de/2023/10/19/power-pv-globale-photovoltaik-revolution-fuer-den-klimaschutz-vom-megawatt-zum-terawatt-teil-i/

@dynode @treibholz @VQuaschning Sorry, i did not know that energy imports and exports are immoral. Im quite fine with the cheap french nuclear based electricity. Their such nice guys sponsoring their lame nukes with 19 Billion € a Year to get rid of their overproduction. An amazing concept.

@mikesorg @treibholz @VQuaschning If you have a problem with nuclear power you shouldn't import it.If you pretend to be "green" you should close down your lignite and gas power plants, don't de-mothball them and even build more gas powered ones.The #energiewende is a fucking joke.

@aerofreak What we need is storage capacity.It’s not how you build a low-carbon grid. As a reminder, in 2011 the authors of #Energiewende authoritatively declared that #nuclear phase-out and switch to #renewables is entirely feasible:https://write.as/arcadian/ideological-origins-of-energiewendeInstead, 12 years later, you ended up with an extremely electricity generated mostly from coal (!) and gigantic redundant generation capacity in PV and wind, which don’t work most of the time, and the CO2 intensity of German electricity is one of the highest in Europe. For example, right now it’s 637 gCO2eq/kWh:https://app.electricitymaps.com/zone/DEFrance’s for comparison is 42 gCO2eq/kWhhttps://app.electricitymaps.com/zone/FR@dynode @VQuaschning

@VQuaschning Germany today - 637 gCO2eq/kWh, in spite of having nearly 120 GW in wind and solar France today - 42 gCO2eq/kWh, while having ~40 GW in wind and solarYou should decide what your ultimate goals are. If your business is sales of Chinese PV panels then of course increase in PV capacity regardless of carbon goals is your profit, but you should at least stop pretending it has anything to do with decarbonization.

@kravietz @aerofreak @VQuaschning Grid-scale storage is vaporware. It hardly exists and is very resource intensive to build and maintain.It's also used as a moved goalpost, if grid-scale storage is implemented "then" all will be good 🤔I do support research of novel ways to store energy, it would be a massive improvement if we could store energy in a practical way and at scale.

@VQuaschning Not to mention that the article is extremely manipulative in its conclusions, because 1 GW of PV with capacity factor of 13% is not in any way equivalent to 1 GW nuclear with capacity factor of 95%. The paragraph when they claim “ 390 gigawatts of photovoltaic power (…) generate as much electricity as, taking into account the lower number of full-load hours 77 nuclear power plants of the 1000 megawatt class” is complete nonsense, because 80% of the time PV produces none or very little electricity so you need a secondary, redundant system to produce electricity when PV cannot - and in Germany that’s coal and gas.

@dynode@treibholz @VQuaschning We couldn't ditch coal right now even back if all the NPP that were once operational in Germany were still in operation.However, now every year some coal plants are taken offline permanently. We're getting there. And faster at that, than before the last NPP were shut down. I don't want to imply a causation here, but still...

@treibholz OK, please have a look once again at the current electricity mix of Germany:https://app.electricitymaps.com/zone/DEAs you can see, Germany has electricity consumption around 60 GW.In terms of production, it has ~60 GW in PV, ~60 GW in wind and ~60 GW in coal+gas. Therefore, Germany has a huge redundancy in the generation capacity in terms of power - in theory, it could generate almost three times more electricity than it needs.But the key difference between 1 GW in nuclear, gas or coal is that it produces energy when you switch it on, while 1 GW in wind or solar only produces energy when there are suitable weather conditions. This is precisely why right now Germany runs mostly on gas and coal - at this moment (06:00), wind operates at ~20% of its available capacity while PV operates at 0.26%, because this is the nature of wind and solar - most of the time they produce much less electricity than their nominal capacity. But since the country expects 24/7 electricity supply, you have to compensate it somehow - and after switching off nuclear the only option for Germany is gas and coal.Now imagine that over the next few years Germany adds another 60 GW, or 100 GW, in wind and/or solar. What does it change in terms of electricity mix on a day such as today? Literally nothing, because 0% capacity times 1 GW, 100 GW or 1000 GW is the same zero watt-hour of electricity, so you’re back to coal+gas.@datenwolf @dynode @VQuaschning

@treibholzWell, in the first place Germany should not have closed the ones that operated already.Restarting them would immediately reduce Germany's CO2 emissions by displacing the dirtiest lignite and coal generation.Building new ones can physically take as little as 4½ years, that has been already proven by Chinese projects.The alternative is to generate electricity from coal and gas for as long as it takes to come up with an industrial scale storage solution, which may be 10, may be 20 or may be 50 years.The biggest manipulation of the "100% renewables" fans is that they present various experimental or prototype solutions at small scale as something ready to power the whole country, which creates an impression that we have a plenty of solutions that "just have to be deployed". But doing that for scaling up from 200 MWh prototype to 200 TWh grid-scale is pretty much like saying "we have a balloon that can fly up to 50 km, so getting to the Moon is just matter of flying higher". It's not, scaling up is an extremely difficult challenge on its own, which is why most of these prospective solutions we've read about 10 years ago (power-to-X, gravitational storage, heat storage etc) are now largely forgotten or remain curious prototypes.And this is exactly how — after decade of looking at various "revolutionary" storage solutions in the news — you end up powering the grid from coal and gas 🤷♂️@datenwolf @dynode @VQuaschning

@kravietz @datenwolf @dynode @VQuaschning Well, in the first place Germany should have started building on renewables way earlier.That’s the mistake. Not shutting down nukes with a 3% portion of the energy mix.But hätte hätte Fahrradkette, now there’s an absolute need for renewables.Restarting (or first repairing) the 3% would do absolutely nothing besides increasing energy prices.

@treibholzGermany already has more than enough wind and solar capacity, and adding more changes nothing.As I explained above, any amount of installed PV or wind turbines produces zero electricity when there's no wind or sunlight.Therefore if you add more of them, you will just get more land occupied by PV and turbines, but no more electricity.And you end up with more coal+gas, because you still want 24/7 electricity.@datenwolf @dynode @VQuaschning

@treibholzI'm not talking about Germany, I specifically write that technically you can build a nuclear power plant in 4½ years and we know it because China just did it a couple of years ago. At the same time, you can clearly see that people in Germany are absolutely ready to even the greatest sacrifice when they face energy shortages. You've been for a decade talking about decarbonization, renewables and phasing out of fossil fuels, but when you needed to replace nuclear you happily switched to fossil gas, and when it was cut by Gazprom, you happily switched back to the dirtiest lignite and coal 🤷♂️So I wouldn't say nuclear restart in Germany is totally impossible. We'll see in 10-20 years when everyone else around will be running on low-carbon nuclear and you'll be still on lignite, maybe then you'll rethink.@datenwolf @dynode @VQuaschning

@treibholzThe following chart shows average build times for nuclear power plants around the world. You can clearly see that majority of the plants worldwide were built under 10 years even recently, there's a few outliers in Europe that were significantly delayed due to political sabotage (inspired by Germany and Russia in many cases), but rest of the world didn't care.@datenwolf @dynode @VQuaschning

@kravietz @datenwolf @dynode @VQuaschning You know that you still need to build those nukes in Germany, right? It doesn’t matter how fast other nations can build them.If all the other countries are running on „low carbon“ (you actually mean: highly dependent on radioactive materials) then Germany can happily import energy from them if needed. Germany doesn’t need own nukes. Neither weapons, nor plants.

@kravietz @VQuaschning You shouldn’t compare one single day as in case of renewable you’ll depend on wind and sun which might not be available every day. In this case you might still need gas. Germany might quit coal in 2030, I’ll hope even earlier if possible
