How is closing your nuclear plants working out for you?

Germany burns the lowest grade coal known to man to make up for the loss of its nuclear fleet. Germany has one of the dirtiest grids in the world and the dirtiest grid in the developed world. And for reference, a single NPP makes roughly 600 GW hours of power a month. Germany closed down about 15 NPPs which would make several times as much power as the solar PV in the article. More than enough to power everyone's ACs.

15 * 600 GWh < 12B KWh.

It'd be even worse if the nukes would be shut down due to lack of cooling water.

Wow, impressive velocity of bullshit claims, but I guess one has to grade on a curve, this is Hacker News of course.

> Germany burns the lowest grade coal known to man to make up for the loss of its nuclear fleet.

Renewables are replacing coal and nuclear simultaneously. Coal usage was consistently dropping before and has continued to consistently drop after the nuclear phase out.

I agree if coal was banned before nuclear, the new renewable capacity added could have done more to replace a huge source of emissions faster. It was a failure of education, media, and political will that Germany phased out nuclear before coal.

> Germany has one of the dirtiest grids in the world and the dirtiest grid in the developed world.

Germany's grid is on average cleaner than the USA, Japan, South Korea and Australia's grids. It's only dirty by western european standards, not by the standards of developed countries. Certainly not by world standards.

Germany is also on a better decarbonization trajectory than any of those countries other than Australia.

Those 15 NPPs were not putting out anywhere near your claimed number.

July 2017: 5.3 TWh

July 2018: 6.1 TWh

Julu 2019: 5.4 TWh

July 2020: 4.2 TWh

July 2021: 5.5 TWh

July 2022: 2.9 TWh

This seems too low by an order of magnitude. In 2021, nuclear power produced 69 TWh in Germany. For comparison, renewables produced 240 TWh in 2021 and 292 TWh in 2025. But I agree with your general point.

The numbers I gave were only for the month of July, not the entire year since the commenter was comparing to the article's numbers for July and claiming that it would have dwarfed the power produced by solar.

By 2017, only 3 German NPPs were online. So multiply those NPP numbers by 5x. Also, your claims about the German grid are non-sense. Germany produces several times as much CO2 per watt generated as the US and about 7x more CO2 per watt as France. You seriously don't even know enough to calculate these numbers correctly.

By 2017 Germany had 8 NPPs online. German nuclear power generation was never at 5x that level. Back in 2010, it was around 2x that level though.

> Also, your claims about the German grid are non-sense. Germany produces several times as much CO2 per watt generated as the US and about 7x more CO2 per watt as France.

I never said anything about France. It does indeed have way cleaner electricity than Germany. The USA does not have cleaner electricity than Germany anymore though according to the source I linked you. Do you have another source you'd like to share?
