That still requires the massive amount of energy needed in extraction and purifying it, which is where the costs come from. I also don't see how we can compare Estonia, of all places, to the US. Much like Brazil with bio-fuels, the US is simply a whole different beast and short of destroying a whole state, you'd never get enough out to be totally reliant on only that resource. If it was viable, it'd have been done by now.
In an emergency situation, destroying a whole state may be perfectly feasable.
Understand that I don't think this is a good result; I think it may be an inevitable result, as we let the problem get so serious that we must engage in exceptionally severe measures to preserve industrial society. If some of those measures include strip-mining half of Wyoming, they will be done, because our society must survive; it will just make things rather ugly.
If we started implementing geothermal and tidal and wave power and nuclear power in large amounts right now and littering the land with windmills and solar cells, if we started stringing cantenary over our railroads tomorrow and stopped building roads and started building interubans and subways and light rail and digging canals and repairing old ones, we would probably not need to touch the oil shale. We would scrape by on coal and conservationism.
But we're not going to do that, so it's entirely possible we'll have to sanction, as you put it, "destroying an entire state" to glean just enough energy resources to keep us limping along for a bit longer until we can finish correcting our own mad foolishness in not starting corrective programmes now rather than later when we all feel the desperate crunch.
