I can only speak for one power plant that I worked a bit on a scrubber refit but they had a rail spur that came right over their coal pile where the cars dumped directly onto it. And I'd expect the truck distance involved would be minimal at the mines as well and, if the figures from CSX are anywhere near correct, rail is a LOT more fuel efficient than trucks for any significant amount of cargo anyhow. I suspect that electric power is overall more efficient..
At the moment it looks like we're interestingly close to getting dependence from foreign oil though. However not everyone would agree about what sales support terrorism..... To be honest the US policy of propping up our own worst enemies seems to imply that we do an awful lot of financial support to the very terrorism we're trying to fight.
