re: Asphalt
I'm in oil & gas business. Asphalt is the oxidized bottom of the oil barrel. It normally has too much sulfur to burn without very extensive acid gas capture. We make our own easily. Article also disregards the Canadian oil sands and our own oil shale, which give us a very large supply versus our conventional oil, especially at prices 50 percent higher than presently. We are also learning how to substitute solar, wind, and geothermal power as an industrial energy source.
