Biofules, biomass , wood pellets et al are a disaster if you believe more CO2 will cause Global Warming.

Does replacing coal with wood lower CO2 emissions?

In sum, although bioenergy from wood can lower long-run CO2 concentrations compared to
fossil fuels, its first impact is an increase in CO2, worsening global warming over the critical
period through 2100 even if the wood offsets coal, the most carbon-intensive fossil fuel.
Declaring that biofuels are carbon neutral as the EU and others have done, erroneously
assumes forest regrowth quickly and fully offsets the emissions from biofuel production and
combustion. The neutrality assumption is not valid because it ignores the transient, but
decades to centuries long, increase in CO2 caused by biofuels.
