The title to this post may seem like an odd question, but I think it is an inescapable one, as I hope to demonstrate. The US Department of Agriculture has a mandate for a huge biofuel planting programme, the largest in the world in 2005. Currently around 13.5 billion gallons are produced per annum. The aim is to grow this to 36 billion gallons by 2022.
Then along came the US drought of 2012. US farmers are asking the USDA to forgo the biofuel mandate. It turns out that that they need all of that corn to keep food prices down.
The fact that biofuels compete with land for food crops and can produce food shortages has been noted by others. The US drought has simply demonstrated that the issue will affect rich and poor nations.
But the dream of using biofuels on a large scale for transportation has always been fanciful. US production targets for biofuels have been based on assumptions about technological developments and the availability and productivity of farmland. A recent report, using satellite data about climate, plant cover and usable land, showed that meeting current US biofuel production targets with existing technology would require “devoting almost 80 percent of current farmland in the US to raising corn for ethanol production or converting 60 percent of existing rangeland to biofuels.”
