There are approximately 3 TRILLION barrels of oil in oil shale reserves, world-wide. Of that 3 TRILLION barrels, the US has at least 62% of proven oil shale reserves, or about 2 TRILLION barrels.
The cost to refine that shale is estimated to stabilize around $50 per barrel.
Why are the democrat/socialists against US energy independance ?
I've always thought these were lowball numbers, but, notwithstanding, $50 sounds pretty high.
Of course, who's to know what extraneous costs the bozos in goobermint will impose on this production, eh?
