It’s worth pointing out that I live in an area where pre-industrial times had all the trees cut down, and it’s full of dense trees now, so all the CO2 released by that charcoal has been recaptured. Even non-sustainably-harvested biomass can regenerate about 6 orders of magnitude faster than fossil fuels do… Fast growing trees could regenerate in 10-20 years. Crops can regenerate in a few months to a year. (Ignoring regeneration time can screw up return on energy calculations, BTW…) I think relying primarily on biomass for energy is a bad idea, but for that last few percent, it’s not bad.
