The renewable industry is still incredibly nascent and does not wield (much) power (yet). In the future, that may not be the case, but to compare this with the existing fossil fuel industries is really quite disingenuous. There's orders of magnitude difference between the two as of yet. Will they become similarly corrupt? Perhaps. Likely, even. But it will shift the profit from massive, world-changing effects to something different, and we're already more tuned into the issue that energy production, consumption, and use has serious side effects.
they already conspired with the fossil industry to kill nuclear power in germany. their minister for energy is "Green" and they're busy reopening coal plants and opening new coal mines to make up for the shortfall of russian gas. they wield immense, malign power.
Does political lobbying have to be done by business, or do the efforts of religious groups to influence policy count as lobbying? If there is a Green lobby then it has more in common with the, I dunno, "Christian lobby" than lobbying from big business.
