Which means she opposes what Ia Anstoot is saying. Thunberg does not view nuclear as a renewable in and of itself, and thus, like Greenpeace, she opposes EU Commission’s decision to include nuclear power in its classification system for sustainable finance (link).
Greta is very scientifically minded and rational, unlike how the media likes to portray her. They use the emotional sound bites and almost never show her referring to paper after paper.
Even if media agencies are not setting out to portray someone like a caraciture they can not help it. That is just how the media is organized nowadays. If Greta shouts something angry in a microphone and they have 7 seconds for a segment about her, then they will use that outburst.
