A Plug for Plugs
CO2 reduction and fuel savings are not the only reasons to own a Plug-in hybrid electric vehicle (PHEV.) There is real value in the ability to plug in to the electric grid which is not captured by price projections.

There will be gas lines.
Alternative energy saw its first flowering during the 1970's and 1980's, fueled by the OPEC oil embargo and late oil shocks which followed the peaking of domestic United States oil production. Demand exceeded supply, and domestic price controls meant that the market could not balance supply and demand; instead gas was rationed by the amount of time your were willing to wait in line.
I will not be surprised if those days come again, nor, I think, will John Petersen, who has recently been trashing the case for Electric and Plug-in Hybrid Electric Vehicles (EVs and PHEVs, a.k.a. vehicles with plugs) on these pages. A friend of mine saw one of John's articles and asked if I felt I had been called an "elitist hypocrite" when he said,
PHEVs and EVs are little more than vanity items for elitists who will happily let up to fifteen other Americans waste up to 2,610 gallons of gas per year so that they can save 462 gallons by driving a 100% green car. The hypocrisy is appalling.
I've said that my next car will be an EV or PHEV, and I admit to being elitist. The days of happy motoring, if not over already, will be soon. We're headed for a society where we own fewer cars, and we drive them less. We may even be heading towards a world in which car ownership will be "elitist." Since I hope that my investments in clean energy will allow me to remain in the car-owning elite, I'm comfortable with being elitist.
Incidentally, John told me "I'll bet dollars to donuts that by 2015 I'll have both an EV and an ICE [internal combustion engine] in the garage, and the ICE won't get a whole lot of use." He notes that, by his calculations, this is not the most economic choice, but he expects most people are far more "sensible" than he is.
Unlike John, I don't expect most people to act in an economically rational manner most of the time, but, as you will see below, I think that the purchase of an EV can be an economically rational choice.
The hypocrisy John referred to comes in believing that subsidies for PHEVs and EVs are better than subsidies for more conventional hybrid electric vehicles, such as the Prius. Again, John and I agree, if the goal is to reduce fuel use and greenhouse emissions, subsidies would be most effective if directed towards high-mileage vehicles of all sorts, with the subsidies proportional to the fuel savings. If the goal is to jump-start the vehicular battery industry, then the subsidies should be proportional to the size of a vehicle's battery pack, whether or not the car has a plug.
So far, so uncontroversial, at least when we remove John's rather incendiary language. So why am I bothering to respond?
A Plug for Real Options
A real option, as opposed to the financial sort, such as the cash-covered puts I'm fond of, is the ability to choose something of value in the real world at a later date. An owner of a PHEV has a real option in terms of fuel. For short commutes, the battery pack is sufficient to drive using only electricity, but the owner can choose to use this feature or not. A PHEV will function quite effectively like an ordinary hybrid if it is never plugged in at all.
This is a real option. Another version of this same option is owning both an ICE and EV, as John expects to do, and an option I argued for in 2007, followed by a look at the demand curve for the PHEV-EV trade-off (and more here.)
Today, under most gas price scenarios, the amount the owner of the PHEV paid for the option, (i.e. the premium of the PHEV over an ordinary hybrid) is probably more than the value of the option. John ran through the necessary calculations to show this in his debunking of the PHEV mythology.
But what happens when there are 1970s-style gas lines? When gasoline carries both a monetary cost and an (unknown) price in time, the real option of plugging in your vehicle and never visiting a gas station rises to the value of the time saved and the increased certainty of being able to get where you need to be. The fuel cost savings are just icing on the cake.
I can't know for certain that there will be gas lines, or some other form of rationing of petroleum based fuels within the service life of my next vehicle, but I strongly suspect there will be, especially in the world's top oil importer, the United States. Even if oil production has not yet peaked, net oil exports from oil producing countries probably have. In a world of declining oil supplies, I have little faith in any government resisting the temptation to use non-market measures to keep what oil it has available to itself. Many oil producers will simply stop selling oil to importers at any price, preferring to keep it for their own domestic and geopolitical purposes. So even if the United States government does not yield to the temptation of oil price caps, rationing may have to occur in some form, be it rationing by price, time, or regulation.
There are easily believable scenarios in the not too distant future in which the real option value of a plug could be the difference between a functioning car and an expensive hunk of metal in your garage, be it a conventional hybrid or an ICE. We don't know if or when we'll see such a scenario. We also don't know that it won't happen.
In an uncertain world, it often makes sense to purchase options, even if they won't pay off in the "most likely" scenario.
