It would defeat the purpose if windfarms made more pollution than they removed, but they don’t. By orders of magnitude. With current processes. They don’t.
Green energy sources like wind and solar don't remove emissions. They add less.
> Energy transition aspirations are similar. The goal is powering modernity, not addressing the sixth mass extinction. Sure, it could mitigate the CO2 threat (to modernity), but why does the fox care when its decline ultimately traces primarily to things like deforestation, habitat fragmentation, agricultural runoff, pollution, pesticides, mining, manufacturing, or in short: modernity. Pursuit of a giant energy infrastructure replacement requires tremendous material extraction—directly driving many of these ills—only to then provide the energetic means to keep doing all these same things that abundant evidence warns is a prescription for termination of the community of life.
But only because those studies were done and numbers were produced.
It's important that we actually prove claims like this with facts.
