Is biomass really a renewable source of energy?
Yes. If biomass is cultivated and harvested in a way that allows regrowth without depleting nutrient and water resources, it is a renewable resource that can be used to generate energy on demand, with little or no net contributions to global greenhouse gas emissions. By burning biomass fuels we release no more carbon dioxide than would have been produced in any case by natural processes such as crop and plant decay and no more than will be absorbed by the plants as they regrow. Secondly, provided our consumption of biomass does not exceed our ability to continually supply the biomass feedstock we use, we have a renewable energy source whose use does not substantially disturb the natural biochemical cycle on a human time scale.
