A special report on feeding the world Plagued by politics

Biofuels are an example of what not to do

“THIS is the craziest thing we’re doing,” says Peter Brabeck, the chairman of NestlĂ©. He is talking about government biofuels targets which require a certain proportion of national energy needs to be met from renewable fuels, most of them biofuels (ie, ethyl alcohol made from crops, usually maize or sugar).
The targets are ambitious. Brazil, Japan, Indonesia and the European Union all say biofuels must supply 10% of energy demand for transport by 2020. China’s target for that date is 5%. America aspires to meet 30% of such needs from biofuels by 2030.
