Energy security and climate change are two of the most significant challenges confronting humanity. What we see, in response, is the familiar capture of policymaking by well-organised special interests. A superb example is the flood of subsidies for biofuels. These are farm programmes masquerading as answers to energy insecurity and climate change. Not surprisingly, they have the depressing characteristics of such programmes: high protection, open-ended support to producers, and indifference to economic rationality.
