In efforts to reduce carbon emissions from coal-fired power plants some operators are replacing coal with biomass--that is, at least some of the time, trees. Though claimed to be carbon neutral, as this video above from the NRDC shows, burning slow-growing trees not only releases all the carbon they've stored into the air it removes the carbon sink from which they came, the forest.Studies have shown that making electricity from fast-growing annual biomass crops does offer genuine reductions in carbon emissions compared to burning fossil fuels--and can be more efficient than converting those crops to liquid biofuels for use in internal combustion engines.
However, this is decidedly not the case when trees are used.
