Don't forget to consider the cost of externalities (environmental damage, health costs), which probably roughly double the true cost of nonrenewable fuels:

Also, as for the comments that oil is still king in terms of absolute price, keep in mind that we probably peaked around 2004:

In my mind, we crossed the peak when diesel became more expensive than gasoline, because that meant that availability/exploration became the primary cost instead of refinement (because diesel has more energy and is easier to refine).

In fairness, we won't reach peak coal for at least several more decades, but my guess is that the externalities associated with coal will become unpalatable once a category 5 hurricane takes out New York City or Florida is under water. Or, when disaster relief crosses say 50% of the government's budget.

I forgot to mention that I'm against all new nuclear unless it can burn waste and plutonium. Partially because I saw the reactors underwater outside Omaha and realized that we are only a human error away from a Fukushima event here in the US.
