Promoting utilization of renewable biofuels

Advancing use of biomass energy

The use of biomass, both at home and at the community level, offers a solution to environmental degradation when used wisely and sustainably.


Biomass, such as wood, animal waste or other organic matter, is perhaps the oldest source of energy in the world. Since primordial times, humans have used the energy stored in plants as a source of food, heat and light. Plants take energy from the sun and store in in chemical compounds through a process known as photosynthesis.

Traditional sources -- dung, crop and forest residues, fuelwood, and human and animal energy -- make up a very significant amount of the energy used in developing countries. Estimates of how much traditional fuels are used vary, largely because of the difficulty in measuring non-commercial fuel use. Recent estimates indicate that in Asia these fuels account for about 65% of total energy use, in Africa, about 85%, and in Latin America, about 20%. This masks an enormous variation both between and within countries.

Biomass offers many advantages for the environment compared to deriving energy from non-renewable fossil fuels. Energy taken from biomass generally adds far less carbon to the atmosphere, thus reducing the contribution to climate change. If new plant material is grown to replace that taken to produce the energy, the little carbon that is released will be reabsorbed, thereby completing the cycle. The low sulphur content of most biomass presents another advantage. Producing energy from fossil fuels, especially coal, is associated with heavy sulphur dioxide emissions, which can lead to acid rain and other problems.


Experts from 15 countries and UN Food and Agriculture Organization (FAO) staff attended the Expert Consultation on Biofuels for Sustainable Development. They studied the use of fast-growing plants, crop residues and manure to produce biomass. Tasks assigned to the FAO at the meeting include among others, the assessment of biomass energy groups, and identifying opportunities for bioenergy plantations.
