Dirty energy seems to be always more expensive than clean energy when
we look at the true cost, but it's cheaper when we look at the market
cost (price). Look at how wind- or solar-powered energy has struggled
to compete, and it's not just the subsidies that the dirty energy
sources get. Now, subsidies may allow the production wind- or
solar-powered energy to benefit from economies of scale, so that this
relative disadvantage goes away. Such subsidies (and the end of
subsidies for and the imposition of taxes on) dirty energy seem a good
idea in any event.

Tom, that's nonsense. I think like a non-economist a lot. (I regularly
present _political_ analysis.) However, for the issue at hand, it's
useful to think like an economist until someone can point to logical
problems with it.

Besides, it's rude to make assertions that someone's thought processes
are flawed (referring to my "inability"). Instead, tell me the
specific logical and/or empirical and/or methodological problems with
what I say.

I assume that the above sentence is an effort to describe the
economist's way of looking at things. But even for economists,
exogeneity and endogeneity are always defined relative to the model or
theory being discussed. What's exogenous for one model or theory
(e.g., the demand for energy) can easily be endogenous in another
model or theory. In making the endogenous/exogenous distinction, I was
_only_ talking about one specific model/theory (the demand for
energy).

This distinction does not have to involve any kind of "nature-like"
thinking (though it does so almost all the time for neoclassical
economists). For example, in the classic experiment on cognitive
dissonance, the message that the flying saucers were going to destroy
the world and the cult should go out to the desert to meet the UFOs
was an exogenous event (engineered by an unethical experimenter) while
the social-psychological dynamics that resulted when the world did not
end (ending with the collective conclusion that the world had been
saved by the cult's faith) were endogenous. The endogenous part was
hardly "natural." It also wasn't deterministic.

The political imperative is based on an economic imperative, the
capitalists' lust for profits. I don't think we should assume that the
government response that you posit is automatic. Maybe. If so, then we
agree. But political processes are hardly deterministic.

I agree that markets without government intervention cannot exist for
long (except when government-like institutions play a role). But I
don't see how we can assume a specific government response. In the US,
we see different government responses to pollution, for example, in
the pre-neo-liberal era of the 1960s and early 1970s than we see in
the current era. Politics is less deterministic than supply & demand.
