      is it right? do you mean 5 acres of poplar plantation )that seem to be a lot
      of land required to just heat a house ( which climate?) the average volume
      of annual growth in north america in coniferous forests is 2,2 cubic meters
      per ha ( less than 1 cubic meter per acre ).i also found an other number
      that say the world volume of annual growth is one cubic metre per person.
