What I like about sceptics is that in good science you need critics that make you think: 'Crumbs have I made a mistake here?' If you don't have that continuously you really are up the creek. The good sceptics have done a good service but some of the mad ones I think have not done anyone any favours.
It is critical to develop a biofuel industry powered by feedstocks produced in every corner of the country in addition to the Midwest. That is why USDA has established five regional research centers working on science necessary to ensure profitable biofuels can be produced from a diverse range of feedstocks.
If you're using first-class land for biofuels then you're competing with the growing of food. And so you're actually spiking food prices by moving energy production into agriculture.
