Don't compare nuclear and renewables, compare both to fossil fuels and greenwashing garbage like biomass and bio ethanol.
Is bio ethanol bad?
The thing with biofuels is that they could be used to feed people instead
It's bad because it uses tons of space and resources that could be used for other things. It also promotes mono culture and it usually uses fertilizers and pesticides that are not necessarily allowed on other crops, as they won't be used as feed.
So, it's bad for biodiversity, bad for land use, bad for resource use. The upside of being a low carbon fuel is completely offset by the impact it has on nature.
Yes, really really bad.
