... The environmental capacity and energy consumption at all stages of generation process could be understood comprehensively using life cycle assessment methodology, thereby considering adopting measures to conserve resources and protect the environment. Figure C-1 presents a simplified process-flow diagram for power generation using biomass, beginning with plant cultivation and ending at the generation stage.

... Considering the consumption of fossil fuel, the cultivation stage still dominates, due mainly to fuel used in the production of nitrogen fertilizer and the use of diesel. As mentioned above, there are three technology routes for biomass power generation.

... are more than 95 percent, suggesting that the CO2 reduction effect of biomass power generation is considerable. In comparison to fossil-fuel and nuclear power plants, renewable power sources also require a large amount of land for a given amount of generating capacity.

... Although producing power from cultivated feedstock is very land intensive, land-use requirements are much lower if waste biomass is used. Land use can serve as a rough proxy for other impacts of new development, including impacts on ecosystems, cultural and historical resources, scenery, and loss of agricultural lands.
