Germany actually replaced the nuclear energy with wind & solar. The argument that remains is that instead of phasing out nuclear, reducing coal would have been preferred. The decision to phase out nuclear has long been made (for good reasons). Keeping them active or even building new reactors of that kind is not an economically viable solution. The price Germany pays for this is higher carbon emissions for the time b…

It's hard for renewables to replace coal or nuclear though, because coal and nuclear provide baseload power, whereas wind and solar are very intermittent and require basically 100% gas backup (as there will be circumstances with very low wind and solar, which tends to happen in europe on very cold, still, winter nights when demand is the highest). There is absolutely no reason the (ex-west) German nuclear power plant…

I absolutely agree with you that we need the coal plants and imports for base load. For a fully renewable grid, we need massive storage capacity. This, however, is far from an unsolved problem. The problem is that the economic incentives aren't aligned with that goal yet. There is reason to be optimistic though, and that the money Germany is saving on nuclear, is more sustainably and effectively spent on renewables and storage.

Germany also produced a multi year net electricity generation low in June. The rise mostly results from this reduction because of the nuclear phase out. These are not the actual numbers but an example: June 2022: renewables 15TWh, total 40TWh = 37.5% June 2023: renewables 15TWh, total 30TWh = 50%

Destatis claims the reason is that demand was measurably lower than 2022: https://www.destatis.de/DE/Presse/Pressemitteilungen/2023/06...

Heating is one thing we have tackle, but also transportation which uses up 27.1% of energy in German. Individual transportation should be a main target, we would all shift from cars to public transport or bicycles. About 40% of distances driven with cars are shorter than 5 kilometers, a distance that's perfect for a bicycle. On top of that, car owners tend to underestimate the cost of their cars[1] [0] https://www.um…

Are you seriously shaming a non-native speaker for their English right now? smh…

Germany didn't replace nuclear energy at all. Germany is producing less electricity than when nuclear reactors were running.

And what conclusion do you draw from this, or rather, how is this relevant to this thread?

By bringing back coal, they killed thousands more of their own people people than if they stayed with nuclear.

Reminds me of my gf who picked cigarettes back up to help her quit vaping.

Yeah, targeting individual transport with inefficient public transport and bicycles while restarting abandoned coal power plants and abandoning running nuclear power plants is going to work wonderfully indeed.

> inefficient public transpor

What do you mean inefficient?

Multiple things can be done at the same time on the country scale. Improve bike infrastructure and public transit, encourage EVs for those that have to drive, decarbonise energy generation, electrify heating and industry, etc.

That this is a big pretend game to make the people responsible of the closing of nuclear power look not that bad in regard of the climate issue. Electricity generation should be increasing as we electrify transportation and heating. If this not what is happening then it means that globally the problem is just displaced. (Which doesn’t work at the planet scale)

Actually Germany recently shut down all of it's nuclear plants and replaced them with the dirtiest fuel possible: lignite coal burning plants. Statistics are a peculiar thing.

The 57.7% figure seems to be a bit misleading in this context. I searched for statistical data on how much idle coal power is held on standby and not included in these statistics, for example, but I didn't find any. Does anyone know where to get full raw data?

Living in Germany is leaving any big city and seeing loads of wind turbines everywhere. I know very little of its economics, like that it typically takes 7 years to pay it back and lasts 20-25 years, but looks like a good way to generate renewable energy and will likely soon take Germany to 100%. It's a goal for the government and for many years it has been pushing forward. I dislike many things here, but I can't say…

At the same time, no animals are living in and near wind farms. Plants that require pollination don't grow because no bees can live in or near wind farms. Building wind farms, also means less space to grow crops, so there will be a food problem. Wind turbines aren't producing energy when the wind doesn't blow.

Nuclear plants would have been a much better solution to the problem.

Maybe this is my tech bubble, but try to find a country with higher Linux/PGP/OpenStreetMap use. I am still trying to put my finger on what the culture difference is precisely, but also outside of tech there's more thinking about what the right/correct/fair thing to do is, even if that brings greater net harm in the end. Example: closing down nuclear because it's not a perfect solution and has risks and waste (ignori…

> not caring that renewables are decades away

Pffft...

If the government wuold decide to buy balcony solar systems for 1.000 Euro each for every household, that would come down to a mere 41 billion Euro for the whole state and that would solve lots of all of this.

They found 100 billion for the Bundeswehr without any problem in the blink of an eye. If you really wanted, the whole energy topic would be set up and solved in a month, from there on it's steady execution.

The reason does not really matter for the math. The record is due to lower production and not a rapid build-up of renewable energy production.
