> That's correct but also irrelevant, as we always had the generation capacity to produce the shortfall ourselves. Just barely. Germany is now dependent on France and Denmark during Dunkelflaute. It doesn't have enough generating capacity to cover for itself. The last year it happened in November: https://energy-charts.info/charts/power/chart.htm?l=en&c=DE&year=2024&interval=month&source=sw&month=11 https://energy-charts.info/charts/power/chart.htm?l=en&c=DE&... and Germany got bailed out by its neighbors: https://energy-charts.info/charts/power/chart.htm?l=en&c=DE&year=2024&interval=month&source=cbpf_saldo&month=11&stacking=stacked_absolute https://energy-charts.info/charts/power/chart.htm?l=en&c=DE&... Germany probably could have managed the last year's Dunkelflaute with the existing coal generation, barely, but it _needs_ those natgas power plants because there's NOTHING renewable that can replace coal. > It was for exactly one hour. And yes, that might still be a problem, if you are on a spot-market rate. But it's also only one of 8440 hours. It was not for just one hour... And even outside of these spikes, the energy is just getting crazy: https://energy-charts.info/charts/price_spot_market/chart.htm?l=en&c=DE&year=2024&interval=month&month=12 https://energy-charts.info/charts/price_spot_market/chart.ht... or https://energy-charts.info/charts/price_spot_market/chart.htm?l=en&c=DE&year=2025&interval=month&month=01 https://energy-charts.info/charts/price_spot_market/chart.ht... . Compare it to 2019 to be amazed. > Again: We haven't even reached the point of renewable overproduction (which is the least one would need for any storage solution to even be an option!). My prediction for Germany: 1. It will phase out coal and replace it 1-for-1 with natgas. 2. The emission decreases will happen almost exclusively due to coal->natgas transition. My napkin math tells me that it can't go a lot lower than 230g. 3. Germany will not be able to perform the EV or heatpump transition. It'll be quietly sabotaged by the government, because there's no way to provide enough generation.

>3. Germany will not be able to perform the EV or heatpump transition. It'll be quietly sabotaged by the government, because there's no way to provide enough generation. Here are a couple of studies from 2012 and 2013, charting a way to 100% renewable energy for Germany by 2050: https://www.ise.fraunhofer.de/de/veroeffentlichungen/studien/studie-energiesystem-deutschland-2050.html https://www.ise.fraunhofer.de/de/veroeffentlichungen/studien... This is a study from 2024, showing 4 different scenarios to reach 100% renewable energy by 2045 (!): https://www.ise.fraunhofer.de/de/veroeffentlichungen/studien/wege-zu-einem-klimaneutralen-energiesystem.html https://www.ise.fraunhofer.de/de/veroeffentlichungen/studien... There are dozens of similar studies from academics and think tanks across the political spectrum. Everyone who actually does more than "napkin math" and doesn't have a vested interest in fossil fuels making money comes to the same conclusion: 100% renewable energy is inherently possible for a country like Germany, especially embedded into a European grid. Is it expensive? Yes. More expensive than using increasingly expensive fossil fuels (the infrastructure for which also has to be renewed periodically) and the consequences of climate change? No, if you believe any serious study on the subject.

  > Here are a couple of studies from 2012 and 2013, charting a way to 100% renewable energy for Germany by 2050 Yep. I know that one. It misses a crucial requirement: tons of coke and LSD needed to drug the lawmakers to let it pass. The price tag for the _lowest_ estimate is around $1T. And it assumes that some miracles happen with power-to-gas and the transition to hydrogen. For that price, Germany can just copy&paste enough AP1000 reactors and achieve CO2-neutrality with known technology. > There are dozens of similar studies from academics and think tanks across the political spectrum. And yet, Germany is planning to rely on fossil natgas until at least 2040-s.

    > Yep. I know that one. It misses a crucial requirement: tons of coke and LSD needed to drug the lawmakers to let it pass. The price tag for the _lowest_ estimate is around $1T. You write this in the same week that German lawmakers actually passed almost $1 Trillion in new debt allowances for infrastructure and defense. > Yep. I know that one. And you conveniently ignore the dozens of other that have been published since and came to the same conclusion: a transition to renewable energy is possible and the cheaper option. > And yet, Germany is planning to rely on fossil natgas until at least 2040-s. Yes, to a constantly decreasing amount. That is the point of a "transition".

      > You write this in the same week that German lawmakers actually passed almost $1 Trillion in new debt allowances for infrastructure and defense. Well, yes. I'm honestly surprised it passed. I guess a shadow of a new war can make even the German bureaucracy move. > And you conveniently ignore the dozens of other that have been published since and came to the same conclusion: a transition to renewable energy is possible and the cheaper option. Your own links provide $1T as the _lowest_ option. More realistic options are more expensive. And ALL of them require the development of new technologies, which is inherently risky. Nuclear is literally cheaper, even if we assume no savings from large-scale production. But it's not being considered, because Greenpeace wants Germany to use coal and gas. > Yes, to a constantly decreasing amount. That is the point of a "transition". And that's the point. The transition could have been already over, if Germany had chosen nuclear in 2000-s.
