Rarely in political history can there have been such a rapid and dramatic reversal of a received wisdom as we have seen in the past 18 months over biofuels – the cropping of living plants, such as soya beans, wheat and sugar cane, to generate energy.
Two years ago biofuels were still being hailed as a dream solution to what was seen as one of the most urgent problems confronting mankind – our dependence on fossil fuels, which are not only finite but seemed to be threatening the world with the catastrophe of global warming.
In March 2007 the leaders of the European Union, in a package of measures designed to lead the world in the "fight against climate change", committed us by 2020 to deriving 10 per cent of all transport fuel from "renewables", above all biofuels, which theoretically gave off no more carbon dioxide than was absorbed in their growing.
Since then, however, the biofuels dream has been disintegrating with the speed of a collapsing card house. Environmentalists, formerly keen on this "green energy", expressed horror at the havoc it was inflicting on the world's eco-systems, not least the clearing of rainforests to grow fuel crops.
As the world suddenly faced its worst food shortage for decades, sending prices spiralling, experts pointed out that a major cause had been diverting millions of acres of farmland from food production to fuel. The damage this was inflicting on the world's poor led a United Nations official to describe the rush for biofuels as "a crime against humanity".
