This region never backed him, I don' recall really any SWVA counties being blue - maybe a few- but I really don't remember any. And if this is the same quote you're talkng about, he never said that, I think you just misread it if these is what you were talking about...
What I have said is that for us to take coal off the table as an ideological matter as opposed to saying if technology allows us to use coal in a clean way, we should pursue it.
That's saying we should not keep talkng about doing something about coal or just throw around ideas, but actually pursue and compliment it.
I think the best way to explain the cap-and-trade idea is from 2008, while Senator/POTUS hopeful said this in on of his speeches..
Enormous good came from... industrial growth, and we are all the beneficiaries of the national prosperity it built. But there were costs we weren't counting, and these have added up now, in the atmosphere, in the oceans, and all across the natural world. And what better way to correct past errors than to turn the creative energies of the free market in the other direction? Under the cap-and-trade system, this can happen. In all its power, the profit motive will suddenly begin to shift and point the other way toward cleaner fuels, wiser ways, and a healthier planet. As never before, the market would reward any person or company that seeks to invent, improve, or acquire alternatives to carbon-based energy. It is very hard to picture venture capitalists, corporate planners, small businesses and environmentalists all working to the same good purpose. But such cooperation is actually possible, and this reform will set it in motion.
And from his campaign site...
..proposes a cap-and-trade system that would set limits on greenhouse gas emissions while encouraging the development of low-cost compliance options. A climate cap-and-trade mechanism would set a limit on greenhouse gas emissions and allow entities to buy and sell rights to emit, similar to the successful acid rain trading program of the early 1990s. The key feature of this mechanism is that it allows the market to decide and encourage the lowest-cost compliance options... A cap-and-trade system harnesses human ingenuity in the pursuit of alternatives to carbon-based fuels. Market participants are allotted total permits equal to the cap on greenhouse gas emissions. If they can invent, improve, or acquire a way to reduce their emissions, they can sell their extra permits for cash. The profit motive will coordinate the efforts of venture capitalists, corporate planners, entrepreneurs, and environmentalists on the common motive of reducing emissions... The cap-and-trade system would encompass electric power, transportation fuels, commercial business, and industrial business - sectors responsible for just under 90 percent of all emissions. Small businesses would be exempt. Initially, participants would be allowed to either make their own GHG reductions or purchase 'offsets' - financial instruments representing a reduction, avoidance, or sequestration of greenhouse gas emissions practiced by other activities, such as agriculture - to cover 100 percent of their required reductions. Offsets would only be available through a program dedicated to ensure that all offset GHG emission reductions are real, measured and verifiable. The fraction of GHG emission reductions permitted via offsets would decline over time.
Does that make sense? I like it.
