Can we afford to spill?

A friend of mine, Harrison, posted this graphic about the BP Deepwater oil spill. The caption reads, "Can we afford to spill any oil?" Um, no I guess not. The graphic shows the damages done by spilling, and I guess how much we need the oil. So, the graphic says, spilling is bad. Ok, sure, but how bad? Bad enough to shut down Obama's proposed offshore drilling? Bad enough to shut down all offshore drilling around the US?

The graphic doesn't have enough information to answer that, so I decided to do some digging, here is what I found:

Based of some numbers I got off a government website, the average amount of oil pumped out of US offshore oil rigs is around 2 billion barrels per year. Suppose that 2010 is peak oil for US offshore rigs and that every year after 2010, the supply dwindles to nothing by 2030. Under these stringent assumptions, that would be 32.6 billion barrels of oil pumped from 2000 to 2030.

There are three main costs that the spill has created, loss of fishing, loss of tourism and damage to wildlife. This website reveals that Louisiana fishing yeilds $2 billion annually. Suppose the spill completely shuts down the LA seafood industry this year and the industry only recovers a little bit each year until after 10 years, it is back to it's $2 billion status.

This EPA website says that the tourism industry for the Gulf Coast is worth $20 billion anually. Suppose the tourism for the Gulf completely shuts down this year and slowly recovers a little each year until 2020 when it get back to $20 billion.

Finally, there was damage to wildlife. This website estimates Exxon-Valdez spill cost $7 billion dollars. So let's assume the same amount of damage from this spill. So in 2010, we lose $7 billion worth of marine life and it takes 20 years to recover fully from the spill.

Using a little present value discounting, the total cost of the the oil spill would be $98 billion.

With that dollar amount in mind, we can find the cost per barrel pumped from offshore oil over the course of 2000 to 2030. So it's $98 billion divided by 32.6 billion barrels which gives us a cost of: $3.02 per barrel.

Spilling really doesn't appear to be much of a cost. Can we afford to spill? No, that's waste, clearly we'd rather not. But does it cost that much? Eh, not really. Should we shut down offshore drilling? No, but we should tax off shore drilling at about $3 per barrel. Why not even make it $4? Even if I undestimated the costs, we'd still be covered*.

*Really love wildlife? Make the cost to wildlife $100 million and the costs per barrel rise to $16. That would still be only about 22% of a $70 barrel of oil.
