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.

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.
