The End of Ingenuity The New York Times Published: November 29, 2006
Humankind’s energy and climate problems are intimately connected. Petroleum’s falling energy return on investment will encourage many economies to burn more coal (which in many parts of the world still has a relatively good E.R.O.I.), but coal emits far more greenhouse-inducing carbon dioxide for every unit of useful energy obtained than other energy sources. Also, many potential solutions to climate change — like moving water to newly arid regions or building dikes and relocating communities along vulnerable coastlines — will require huge amounts of energy.
Without a doubt, mankind can find ways to push back these constraints on global growth with market-driven innovation on energy supply, efficient use of energy and pollution cleanup. But we probably can’t push them back indefinitely, because our species’ capacity to innovate, and to deliver the fruits of that innovation when and where they’re needed, isn’t infinite.
Sometimes even the best scientific minds can’t crack a technical problem quickly (take, for instance, the painfully slow evolution of battery technology in recent decades), sometimes market prices give entrepreneurs poor price signals (gasoline today is still far too cheap to encourage quick innovation in fuel-efficient vehicles) and, most important, sometimes there just isn’t the political will to back the institutional and technological changes needed.
We can see glaring examples of such failures of innovation even in the United States — home to the world’s most dynamic economy. Despite decades of increasingly dire warnings about the risks of dependence on foreign energy, the country now imports two-thirds of its oil; and during the last 20 years, despite increasingly clear scientific evidence regarding the dangers of climate change, the country’s output of carbon dioxide has increased by a fifth.
As the price of energy rises and as the planet gets hotter, we need significantly higher investment in innovation throughout society, from governments and corporations to universities. Perhaps the most urgent step, if humankind is going to return to coal as its major energy source, is to figure out ways of safely disposing of coal’s harmful carbon dioxide — probably underground.
But in the larger sense, we really need to start thinking hard about how our societies — especially those that are already very rich — can maintain their social and political stability, and satisfy the aspirations of their citizens, when we can no longer count on endless economic growth.
