· Biomass is a diffuse source of energy, with low energy density.
· Modern technologies need concentrated energy sources with very high energy density. This is why traditional energy sources have declined and our age has seen such extraordinary growth of energy use and demand .
· Biomass is a diffuse resource, arising over very large areas and thus requiring large land areas with substantial collection and transport costs.
· Photosynthesis is the most effective route to convert solar energy into Biomass.
Biomass is the most convenient form to store solar energy.
· The use of biomass for energy is also desirable in a more complex, holistic sense
The use of Biomass can help
· to protect fossil energy sources, diminish their exploitation and prolong their availability.
· to protect the environment, by reducing pollution and global warming.
· to reduce unemployment in rural lands with low agricultural potential.
