The second chart says “public electricity generation”, what does that refer to and what percentage of total electricity consumption does that account for. For example, does this include the share of electricity used in the industry or is this public usage in homes?
Net generation of power plants for public power supply.
Says the description. As far as I can tell this means all electricity supplied to the public grid, which includes industry unless they have their own private power-plant.
Ok, so assuming that’s what that means as it stands, renewables produce around half of electricity. The jump to 65% seems pretty ambitious given prior data.
However, as I’ve already noted, the real question is around the lifecycle costs of the renewable infrastructure. For example, wind turbine blades need to be regularly replaced. This means blades have to be manufactured, and delivered, and installed, while old blades need to be disposed of. All of this requires energy to do. If you just externalize these costs that creates a skewed picture.
Yes indeed the overall picture isn’t so rosy, but I never claimed anything else. It could be much better though if the Merkel government had not sabotaged it in the last 15 years.
Also the live-cycle cost apply to any energy production facilities and are the main reason why Germany phased out nuclear, as the life-cycle (and political) costs were too high.
I think we’re in agreement that the picture could’ve been much better. I specifically said that this isn’t a competition between nuclear and renewables, but lack of interest on the part of the government to move off fossils.
And you’re right lifecycle costs apply to any energy production. However, nuclear fares much better than alternatives when it comes to lifetime costs.
Seems like the issue with nuclear is purely political, and this appears to be a problem across the western world with the exception of France.
One can argue that this is not necessarily true as there are some examples from France and Japan (and more recently China) that show it can be built in a non-cost prohibitive way. But actual more recent examples from Europe (including later French constructions) were all delayed 10+ years and cost triple or so of the original cost estimates. Again one can argue that this is mostly a result of state-capture and corruption, but it makes it very hard to justify new reactor constructions and I think that is a realistic assessment of how any such project would have gone (wrong) in Germany as well.
This goes back to inability to build any kind of alternative infrastructure be it nuclear or renewables. As you’ve repeatedly pointed out, Merkel’s government sabotaged renewable infrastructure investment as well. It’s possible things may change going forward out of necessity, but so far it seems like things are getting worse as opposed to better.
The difference is that wind and solar managed to reach about 50% of the total electricity production despite being obstructed by the former government and the large traditional power-producers in almost every way possible.
But the bigger problem right now is actually that due to this state-capture / sabotage there are hardly any local producers left (this pre-dates both Covid-19 and the Ukraine war) and the producers that are left in Asia produce the equipment with a significantly more fossil fuel heavy energy mix and require a much longer fossil fuel consuming transport.
Again, it’s misleading to focus strictly on electricity production. Before Germany started rolling nuclear back it was providing 11% of overall energy. Which is comparable to what renewables are currently providing.
It seems to me that similar types of policies prevented mass adoption of nuclear and renewables. And as you point out, importing infrastructure is not really a great solution either.
I don’t see how the problem gets solved until Germany gets a sane and stable government that is willing to do a long term commitment to moving off using fossils.

Furthermore, as you yourself have noted, electricity production is only a small portion of the overall picture. Renewable share in gross final energy consumption reached only 19.2% in 2021: https://www.umweltbundesamt.de/en/topics/climate-energy/renewable-energies/renewable-energies-in-figures
So, overall picture is far less impressive.

See my comment further above. The problem is too high costs and construction delays.
