Generation specific cultural references can be treacherous ground for bloggers because the flashback effect is usually limited to readers with long and vivid memories. In this case, however, the lessons of history are so relevant that I'll accept the risk and offer some context for younger readers.
In my youth a war wrapped in the liberal ideology of the Kennedy and Johnson administrations and fueled by an underlying concern over who would control vast oil and gas resources was fought in the jungles of Vietnam, Laos and Cambodia. By current standards, the toll of 47,424 battle deaths was staggering. By the late '60s opposition to the War was widespread and a galvanizing force behind the antiwar movement was music, including an iconic folksong from Pete Seeger, Waist Deep in the Big Muddy.
While my use of an antiwar anthem to make a point about plug-in vehicles is certain to draw howls of outrage from advocates and true believers, I think the analogy is apt because the ideologically inspired road to disaster we trod during the late '60s is frighteningly similar to the path we're on today with plug-in vehicles where the prevailing attitude seems to be "damn the facts, push on."
Our fundamental energy problems are easy to identify – increasing oil prices and increasing reliance on imports. Both numbers have been climbing steadily for decades and consumers have been stubbornly reluctant to change their behavior in response to prices. The burden on the economy becomes heavier with each passing year and if you're willing to extend the current price channel out for another decade, oil price expectations in the $150 to $180 per barrel range don't seem all that far fetched.

For as long as automakers have been proposing plug-in electric vehicles, skeptics like me have been noting that fuel savings are unlikely to give consumers a cash-on-cash payback of their incremental cost over the life of the vehicle, much less the three to five year window that consumers typically expect. There are countless vague promises about economies of scale driving down costs as the industry matures, but at least in the battery sector where raw materials and plant automation are the primary cost drivers and labor is almost a rounding error, I have a hard time banking on a fairy godmother to restrain commodity prices and equipment costs. While the following graph of long-term industrial and precious metal prices from Credit Suisse is a little dated, it certainly has the same general shape and slope as the most recent decade on the oil price chart.
"We were knee deep in the Big Muddy, the big fool said to push on."
For several years realists like Vinod Khosla and others have noted that since the U.S. gets roughly 50% of its electricity from coal and will likely do so for decades to come, the environmental benefits of plugging an electric vehicle into a lump of coal will be few and far between. Last week, I offered a simple comparison of plug-in vehicles with the best available plug-free automotive technology that proves plug-ins are about one-quarter as effective at reducing oil imports as cheaper HEVs that can point to a decade of performance under real world conditions.
"We were waist deep in the Big Muddy, the big fool said to push on."
The real flies in the ointment are that plug-in vehicles don't significantly change the energy balance, they're far too resource constrained to make a dent in oil imports, and the fundamental economic premise only works if you are willing to assume that historically moderate trends in retail electricity prices will continue forever.
From an overall energy balance perspective, plug-ins don't change the amount of energy needed to move a vehicle down the road. Instead, they merely move the conversion of fuel to energy from under the hood to a local power station while increasing vehicle cost by 50% to 100%.
Likewise, the batteries that will be used in plug-ins are made from raw materials that are orders of magnitude less abundant than oil. The resource constraint issues go far beyond lithium availability and extend to every component in batteries and battery packs. Those materials all have alternative uses in high value products and from a resource availability standpoint, using batteries to conserve oil is a lot like using gold to conserve copper.
Finally, it's almost impossible to find a newspaper or magazine that doesn't have several articles on the evolution of the electric grid. We're seeing massive investments in wind and solar power installations and the estimated cost of the coming smart grid runs to trillions of dollars. Since the one certainty is that private capital will not finance alternative energy or the smart grid without expecting both a return of capital and a return on capital, it's patently absurd to believe that electricity price increases will remain as benign in the future as they have been in the past.
"We were neck deep in the Big Muddy, the big fool said to push on."
When I was but a lad one of my mother's favorite quips was "use your head for something besides a hat rack." It was her way of teaching me to look beyond my immediate circumstances, consider the factors that led me to a decision-point and reflect carefully on the likely consequences of my actions.
If it weren't so damned expensive, I'd describe vehicle electrification beyond the HEV stage as a zero sum game. Given the immense costs that are becoming increasingly clear with each passing day, I'd characterize it as a game where we can't reasonably hope to break even.
