Here in California the Biomass that is used for generation is from vineyard and orchards, however we have over 60 million dead conifer trees standing in the Sierras from drought and Western Pine Bark Beetles. I would prefer they be burned in a biomass plant under hotter combustion and generate less polution that open burning.
I think you are naive if you think whole live trees aren’t being cut down and burned.
