The airline industry has no future. The same is true for airfreight. No air carrier has a viable plan to make a profit with oil at current prices—much less in years to come as the petroleum available to world markets dwindles rapidly.
That’s not to say that jetliners will disappear overnight, but rather that the cheap flights we’ve seen in the past will soon be fading memories. In a few years jet service will be available only to the wealthy, or to thegovernment and military.
Sir Richard Branson of Virgin Atlantic says he wants to use biofuels topower his fleet of 747’s and Airbuses. There are still some bugs to beworked out in terms of basic chemistry, but it might be possible inprinciple—if only we could make enough biodiesel or ethanol withoutfurther driving up food prices and wrecking the soil. Even then itwould be very costly fuel.
Are there other options for powered flight?
Hydrogen could be burned in jet engines, but doing so would require a complete redesign of our commercial aircraft fleet, and H2 would be expensive to make—unless the growing trend toward more costly electricity (as we phase out depleting, polluting coal and increasingly scarce natural gas) can somehow be reversed.
Last year I was invited to give the keynote address at the world’s firstElectric Aircraft Symposium. NASA and Boeing sent representatives, butall told there were only about 20 in attendance. The planes beingdiscussed were ultralight two-seaters: that’s the limit of current orforeseeable battery technology. These might come in handy in a futurewhere they are the only option for emergency air travel (blimps need depleting helium or explosive hydrogen). But forget about 300-seat planes running on solar or wind power, ferrying middle-class vacationers to Bali or Venice.
There are good reasons to cut down on air travel voluntarily: flying not only swells our personal carbon emissions but spews CO2 and other pollutants into the stratosphere, where they do the most damage. However, the worsening scarcity of the stuff we use for making jet fuel takes thediscussion out of the realm of optional moral action and into that ofeconomic necessity and personal adaptation.
I fly to educate both general audiences and policy makers about fossilfuel depletion; in fact, I’m writing this article aboard a plane enroute from Boston to SanFrancisco. I wince at my carbon footprint, but console myself with thehope that my message helps thousands of others to change theirconsumption patterns. This inner conflict is about to be resolved: thedecline of affordable air travel is forcing me to rethink my work. I’malready starting to do much more by video teleconference, much less byjet.
Those who live far from family will be more than inconvenienced, as will the hundreds of thousands who work for the airline industry directly orindirectly, or the millions who depend on tourism or airfreight for anincome. These folks will have few options: teleconferencing canaccomplish only so much.
Our species’ historically brief fling with flight has been fun,educational, and enriching on many levels to those fortunate enough tobenefit from it. Saying goodbye will be difficult. But maybe as we dowe can say hello to greater involvement in our local communities.
