Ken, I think you are somewhat misunderstanding the political dynamics of "the climate debate".
I don't think that protection of fossil fuel companies' profits is the controlling political issue.
I think that it is mainly the unwillingness of the public at large to accept the proclamations of the government that their lifestyles must change as directed by the government.
It is unwelcome, even scary news, and can be conflated with other unwelcome news from the same government about other things that do not seem to be well founded scientifically, but are being pushed politically. So, the environmental degradation debates get dealt with in the public mind as just something else that must be resisted from a source that is not trusted - for all sorts of reasons.
There are politicians who intentionally use that resentment, and even try to fan it into outrage, for the purpose of gaining political power. And, that seems to be a very effective strategy at this point in time, and not just here in the U.S.
To get over that, we are going to need to show the public solutions to the problems that are acceptable to (most of) them. We can't expect to succeed by simply outlawing what the public has been doing and expect them to "find a way" to deal with it somehow. And, by "show", I don't mean simply writing a technical paper that is claiming something is possible or even profitable. We will need to have "first adopters" actually demonstrate that something works acceptably well and is affordable for nearly everybody.
Governments try to do that sometimes with subsidies for new things. Solar is a good example. But, too often, the manipulated economics of the subsidies are used to incorrectly claim affordability for all, even though it is well known that the subsidies can only be affordable at small fractions of market penetration. Again, solar has been a good example of misleading statistics on affordability at both the residential and grid levels. There is sort of a race between getting the savings from mass production to offset the losses of subsidies as market penetration increases. Sometimes that can work. But, it is not a foregone conclusion that it always works. And people have a right to fear that assurances that it is working may not be true from governments and activists. But, seeing their neighbors happy with it is a huge selling tactic.
