Hi Jim - Like everything, there are a lot of details that one has to get right about utilizing forest biomass as a source of energy. One of the critical ones is that energy input required for long-distance transportation of fuel can quickly have an adverse effect on the net carbon budget - this is why, as you point out, it is a much more effective approach implemented using many small, local facilities, than a few massive factories. The forest management side of it also is something that has to be done right. In addition to the issues that you raise about degradation of soil organic material, the use of invasive exotic species as a biomass can be so problematic, that in my opinion it should be completely avoided. Here in the northeastern US, we are blessed with a mixed deciduous forest that I believe is highly amenable to utilization for forest biomass, but unfortunately this has received very little attention. I think that it is unfortunate that too many people consider cutting trees to be somehow intrinsically immoral - it is a strange thing, that somehow perhaps most Americans consider agricultural land use and harvesting to be a responsible and sustainable activity, while any sort of forest utilization is viewed as inherently unsustainable and immoral. The reality is that informed forest utilization has a much smaller impact on wildlife, water and air quality than most forms of agriculture but most people don't seem to understand this... 

If one needs an illustration of the potential for the use of forest biomass as an energy source, you should turn to Sweden. That country currently obtains over 30% of their total energy usage from forest biomass and they are on target on the road to eventually obtaining 50% of their energy from this source. This has all been done while minimizing non-desirable air emissions and avoiding soil and water degradation.

I think I want to read the decision and the facts of the case before I
jump to conclusions.  While biomass "recycles" carbon instead of
releasing fossil carbon, biomass facilities also encourage
clear-cutting, and clear-cutting generates significantly more CO2 from
degradation of soil organic matter than from the biomass burned
directly.  This "carbon debt" means that it may take 75 years before a
forest regrows and stores enough carbon to make up for what was lost by
clear-cutting.  The few studies available suggest that the energy and
carbon balance for biomass may make sense for small local facilities,
but the balance tips against large industrial-scale facilities.  While
it may seem counter-intuitive, the science does not automatically favor
biofuels as a solution to global warming, and we need to let reality
drive air pollution policy.

This strikes me as a very poorly informed decision.  Burning
forest-derived
biomass is potentially highly desirable from a carbon standpoint. The
carbon contained in trees will be released into the atmosphere
regardless
of whether it does so by combustion or via decomposition, and is
therefore
a truly "carbon-neutral" source of energy. If it is utilized in place of
burning fossil fuels, it can greatly reduce net carbon emissions.

Whoever these people are in the Clean Air Task Force, Conservation Law
Foundation and the Natural Resource Council of Maine, I think they would
benefit from studying a little bit of ecosystem science. There efforts
are
clearly mis-placed which is unfortunate...
