Massimo suggests natural gas. I don't know how nat. gas supplies will hold up under a massive conversion to that fuel. I had not heard until recently about converting nat. gas to diesel. Nat. gas is a valuable feedstock for industrial use. I suspect that it has not been explored for as intensively as oil, so I have no idea when a Hubbert's peak would occur.
I am sure we have an expert here. -- Michael Perelman Economics Department California State University Chico, CA 95929 Tel. 530-898-5321 E-Mail michael at ecst.csuchico.edu
