Matthew Rojansky has a post at Across the Aisle on energy independence that caused me to bang my head against the wall in sheer frustration for a few moments.

Rojansky reacts to a DC panel on energy, the environment and national security at a Center for American Progress/Century Foundation conference. After all of the panelists politely point out that the goal of energy independence is neither possible not worthwhile. Rojansky replies:

Alright, I see their point. It’s not immediately clear that even the optimal combination of conservation and alternative energy technologies can keep pace with growing demands for energy, meaning we will continue to need energy imports to fuel the US economy. Cutting off foreign energy sources would, by that reasoning, make us less competitive, and more “isolated” in a negative sense.

But there’s another side to that coin.

Energy is a zero sum game. Unlike trading technologies or other complex goods, trading energy commodities does not create value. In fact, the immutable laws of physics dictate that transmission of oil, gas or any other store of potential energy costs more energy the farther it has to travel. At some point, in fact, you could expend more energy to transmit a gallon of gas than you could ever get out of that gallon, resulting in a net energy loss.

Thus, importing energy from abroad only works as long as that energy is both cheaper to extract and transport than it would be to generate here at home, and–here’s the real key–as long as the governments that control the resources are willing to sell them to us.

Trading energy is not a zero sum game.

This doesn't mean policymakers should necessarily let the market operate in an unfettered manner. There are clear non-economic reasons to intervene (Rojansky argues that foreign suppliers might decide one day not to sell their energy to the U.S. That's a red herring, because any move in that direction hurts them more than us). Efforts to reduce greenhouse gas emissions will likely require investment in alternative forms of energy. The political externalities of high energy prices are also undesirable. However, even factoring in the political externalities, the U.S. should not aim for energy independence. Why waste resources on eliminating that last drop of imported oil, when perfectly stable and friendly economies like Canada, Mexico, Norway, and Great Britain are willing to seel their energy to us?

Rjansky closes his post with the following critique:

The experts I cited above object to the energy independence slogan only because they perceive it as a red herring. They would argue it is a distraction from broader conservationist goals that will, in reality, have the same important impact in reducing our dependence on foreign oil, while combating global climate change by reducing carbon emissions. Certainly, climate change is very important, and a preoccupation with energy independence for security’s sake alone might lead us to transition to US-sourced fossil fuels, like coal and oil from ANWRA, that produce just as much harmful carbon as Middle Eastern oil and gas. But to call energy independence a bad idea destroys the only common ground in this debate, and hence the best chance for meaningful progress on both national security and climate change.

Policymaking is 10% reasoned argument and 90% political compromise, as I’ve been very recently reminded, and I am surprised that such an impressive group of Washington insiders would be so short-sighted about our national interest.
