Let's hope not. Biofuels based on corn and other food crops are bad for obvious reasons, but even non-food biofuels have their risks - among them degradation of the American/Canadian Great Plains, ecological degradation in the Third World, and the risk of invasive species (most of these non-food biofuels are fast-spreading grasses).
The most ecological energy policy is to stop the government from subsidizing oil (by building suburbia with land use restricitons), subsidizing coal, and subsidizing water. There is no magic fuel out there that will allow us to consume infinite amounts of cheap energy - nature made extracting energy expensive for a reason, and the government needs to get out of the business of trying to make it easier.
