I don't think it's a huge success, considering they're unable to meet their own demands for electricity, instead driving up energy prices in neighboring countries as well.

This. Germany has been strong arming policies around electricity in the EU for quite a while. Forcing their neighbors to sell their electricity for cheap when it is the most expensive in the market while assuming none of the costs and risks.

And they are disrupting neighbors' energy production economics when they offload their overproduction precisely when nobody wants it.

That's German superiority complex in all it's "glory".

The problem of meeting demand is in industrial use and residential heating, both of which aren’t typically electrified in Germany. The problem has more to do with an active war and an industrial sector built on cheap Russian gas.

That is largely due to the war in Ukraine and Russian gas/oil being a big no-no in Europe right now.

Continuing to burn fossil fuel is simply not an option. Not if we want to comfortable keep living on this planet.

None of the European countries meat their energy demands by themselves. All of them regularly import and export electricity from/to their neighbors. That's a good thing and is driving down electricity prices not up.

The reason countries buy electricity from their neighbors is because it's cheaper not because they couldn't meat the demands themselves.

Now Germany is by no means perfect, heating is largely gas based which increases emissions. Ironically the law that was trying to change this, had a big counter campaign that likely contributed to the change of government.

So while the greens energiewende are often blamed for Germanys dependency on gas (although the dependency had been going for much longer), it's the conservatives who likely had a much bigger impact on Germany sticking with gas by preventing to move heating to electricity.

It's a huge success considering where they would have been if not for doing that, and then energy prices would have been higher still.
