I can’t turn on the television these days without hearing some politician advocating the achievement of energy independence. Not a single time have I heard one pushing for banana independence. Yet we import all our bananas from foreign countries and some of them don’t like us all that much.

The only half-way valid argument for energy independence is national security. If our foreign sources of oil were cut off we could be practically dead in the water after our strategic petroleum reserves are exhausted. For that reason we should be preparing all our known oil fields for production and exploring for more. We should also be developing alternative sources of energy.

But there is no reason to stop importing foreign oil as long as its price is competitive with domestically produced oil. It makes sense to me to keep using the foreign oil as long as we can get it and afford it, and save ours for later. That is, use theirs and hoard ours. If foreign oil becomes unaffordable and threatens our economy we could increase domestic production to hold the price down.

The politicians also rant about the hundreds of billions of dollars we are sending to the Middle East each year to satisfy our “addiction” to oil. They speak as if the money is being poured down a rat hole. Actually, if the foreign recipients of our dollars are pouring them down a rat hole or storing them in a vault, the oil we get from them is effectively free. We could just print more money to replace what they are holding.

But that’s not how it works. We engage in a voluntary transaction with the foreigners in which we get oil and they get US dollars. The only place on the planet where US dollars can be redeemed is in the US. The dollars that they accept in exchange for their oil are effectively promises that they can come to the US later and exchange them for goods, services or property. They may choose to trade the dollars to some other country but that country still has to spend the dollars in the US. So, in the end, all that money sent abroad has to eventually come back and when it does it creates commerce (and jobs) here. This is true of all other forms of foreign trade as well.

This process still might work to our disadvantage if we pay too much per barrel of oil. We were recently paying about $140 per barrel. A Saudi could (but probably wouldn’t) stay overnight in a decent hotel in the US for that amount. We get about 20 gallons of gasoline and numerous side products from the barrel of oil. Is that a good trade? I don’t know but a free market will.

Energy independence sounds good but let’s not go there as long as foreign oil is comparable in price to domestic oil and we are ready to tap into our known deposits in case of a national emergency.
