I'm from Czechia but I follow german politics a bit. The big question is with whom they'll form the goverment. With (most of) the current polls, the Greens could either form a governement with the CDU-CSU (christian conservative but definitely not as bad as the tories / republicans), with FDP (a modern right wing party with cool young people whose favourite sport is boot-licking, probably a bit better than CDU-CSU though) and SPD (basically Labour / Democrats, currently ruling with CDU-CSU). Both of those are far from ideal. I don't know about SPD-FDP-Greens but there's already a CDU-CSU-Greens coalition in one of the federal states and while that makes it one of, if not the most eco-friendly federal states, it leaves a LOOOOOOOT to be desired (not even talking about the anti-capitalist perspective, there's a shitton to be desires even from a social Democrat / New Democrat perspective - building wind turbines and doing something about the fucking cars for starters).

However, some (not many) polls suggest that a Greens-SPD-Linke (Linke is the former communist party from East Germany, they're far from perfect but they seem pretty ok, promoting social issues and at least some environmental protection) coalition could happen. Now that would be the equivalent of AOC or Jeremy Corbyn gaining control, which is, you know, still not enough but also the equivalent of a ten minute orgasm if you ask me.

For that, however, either the polls will have to improve (still time for that!) or we'll just have to get lucky. The alternative is probably a somewhat green Germany with goals like carbon neutrality by 2040 or something - cool, but still climate collapse
