My preferred energy answer: all of the above. Great topic, random thoughts:
-
I love the idea of alternative energies, and we need to invest in them. But fossil fuels aren’t going anywhere, and remain the most economically feasible energy source. So, to suggest that there is an “either-or” is wrong, we need all. We simply need to be realists about fossil fuel.
-
We are going to consume fossil fuels (a lot) in the near and medium term. It’s going to get pumped out of the ground, and we’ll use it. Why not pump our own, where we can be assured of a better, lighter environmental impact than if we “outsource” to countries that don’t have our environmental sensibilities? The oil will be pumped out of the ground, regardless - better that we do it, for environmental reasons.
-
Better that we do it, for energy security purposes as well, but the fungibiilty of oil in world markets doesn’t mean that just because we pump it, we consume it, and therefore we are more energy-independent. If we pump it, we’d lower the prices (more supply), but that wouldn’t necessarily translate into dmoestic consumption of domestically-pumped oil and our independence from bad countries. We’d need to address this in ways other than domestic-exploration.
-
We need alternative energies because of diversification benefits. Like any asset portfolio, there are inherent dangers in overconcentration in one area. We are overconcentrated on fossil fuels, and we need to diversify. That way, even if we have oil “shocks” or bad oil politics from the Middle East, we’re insulated better from their shenanigans.

No, we shouldn’t rely solely on the market to dictate the path of energy, because too much of it is implicated in national security. Consumers are not (and should not be) charged with making national security decisions through their consumption preferences, and we don’t want to sit back and live with the results the market has come up with. That doesn’t mean I believe in the nationalization of energy - it just means that, realistically, for this issue, pure market economics may not and too often won’t lead to results we need.
