JEFF CARTER: I wish we were using more oil. “The question we should be asking ourselves is not how we can conserve, but how can we best produce energy at the lowest marginal cost? There are three ways to do that: Nuclear, coal, and natural gas. They are cheap, abundant, and for national security bugs they are in our own country. Without new sources of them, we won’t expand our economy as fast as we could. Existing supply chains will become constrained, driving up the cost.”
