Paul, I would like to disagree with you, not that biofuels are bad, but
an area with "a lot of biomass" may still have a fragile enough
ecosystem that burning the biomass (instead of fossil fuels) may be
disadvantageous. Consider England, at one time it had huge supplies of
wood, now there is little growing. The forests were burned as fuel and
used as masts for wind powered ships, the forests are no more.
Hopefully we will be wise enough to use the best fuel for a given area,
and not destroy the ecosystem by saying something like "Fossil fuel is
bad, use biomass." without carefully examining the impact of use of
biomass. Take all the "waste biomass" from the fields and suddenly
there can be a problem which requires adding something back to hold and
supply some of the nutrients.
