RANDALL PARKER ON OUR ENERGY FUTURE: “I’m starting to think that the transition away from oil does not totally depend on fuel efficiency and electric cars. The dramatic increase in accessible shale natural gas reserves makes cars converted to natural gas another way people can adjust to declines in oil production. While the converted cars have downsides (e.g. conversion costs, shorter range, and less trunk space) conversion of a car to run on natural gas is far cheaper than conversion to run on electric power.”
