Amen. And the thing to keep in mind when talking about biofuels is that one
year's current consumption of petroleum products represents roughly 400 years
of stored solar energy. You just can't get there with biofuels. The only ways
around the limitation imposed by solar budget are technologies like nuclear
fission and fusion, which do have their drawbacks.
