Prospect has published my essay on bioenergy, in which my research left me astonished at the environmental and economic harm that is being perpetrated. Biomass and biofuels are not carbon neutral, can't displace much fossil fuel, require huge subsidies, increase hunger and directly or indirectly cause rain forest destruction. Apart from that, they're fine... Here's the text: From a satellite, the border between Haiti and the Dominican Republic looks like the edge of a carpet. While the Dominican Republic is green with forest, Haiti is brown: 98 per cent deforested. One of the chief reasons is that Haiti depends on bioenergy. Wood-mostly in the form of charcoal-is used not just for cooking but for industry as well, providing 70 per cent of Haiti's energy. In contrast, in the Dominican Republic, the government imports oil and subsidises propane gas for cooking, which takes the pressure off forests.
Haiti's plight is a reminder there is nothing new about bioenergy. A few centuries ago, Britain got most of its energy from firewood and hay. Over the years the iron industry moved from Sussex to the Welsh borders to Cumberland and then Sweden in an increasingly desperate search for wood to fire its furnaces. Cheap coal and oil then effectively allowed the gradual reforestation of the country. Britain's forest cover-12 per cent-is three times what it was in 1919 and will soon rival the levels recorded in the Doomsday Book of 1086.
Yet if the government has its way, we will instead emulate Haiti. In 2007, Tony Blair signed up to a European Union commitment that Britain would get 20 per cent of its energy from renewable sources by 2020. Apparently neither he nor his officials noticed this target was for "energy" not "electricity." Since much energy is used for heating, which wind, solar, hydro and the like cannot supply, this effectively committed Britain to using lots of wood and crops for both heat and electricity to hit that target. David Cameron and Chris Huhne, anxious to seem the "greenest of them all," dare not weaken the target, despite its unattainability.
