"Dendro"  is a prefix that means "wood",  from ancient Greek "dendros" meaning "tree".   It is not a word in common usage yet, but i 'm pretty sure it will be in the  near future.    Advances in wood burning technology have made generation of electrical energy from wood much more practical.   Burning fossil fuels like coal or oil add carbon to the atmosphere,  but burning wood is considered carbon neutral as the carbon in trees was recently in the atmosphere and would be added anyway when a tree dies and rots.    It is possible to save some of the charcoal produced during the process before it totally burns so that the process is actually carbon negative,  sequestering carbon out of atmospheric circulation and producing a useful fertilizer .   Wood is produced most effeciently by  coppicing, or cutting trees so they resprout from the roots,  leaving the soil intact and making very little environmental impact compared to clearcutting.   This ancient practice combined with efficient modern techniques is leading to new, ecologically integreated patterns of energy production that are very practical and practicable in areas with significant forest resources.
