In this case the other 62% is only $5.1 billion, which averages out to about $15 per person across the US. Since this is reflected in wholesale electricity prices I assume it is even enough that after accounting for unequal impact, it still isn't that high. It seems like a problem, but not a major one.
Well, since it’s “only” $5.1 billion, the trillion dollar valued companies should have no problem paying costs in full rather than seeking subsidies from the hapless taxpayers.
That average is a false equivalency since the cost subsidy will be localized to the regional power provider typically the state-run monopoly or some other large provider. It's not an even distribution and the core thesis of the article, that the lower-income folks are the ones subsidizing it, likely still holds because land is historically cheaper and is generally less developed by municipal and state govts when its residents are lower-income and/or a minority population, and local distribution (and costs) impact those with less (usually no) disposable income by which they can improve their household energy efficiency.
