Popular Initiatives

• Dedicated energy plantations:– 3 million ha of eucalyptus plantations used for charcoal

making (Brazil); – Plantation program for 13.5 million ha of fuel wood by

2010 in China; – 16000 ha of willow plantations used for the generation

of heat and power in Sweden; and – 50000 ha of agricultural land has been converted to

woody plantations, possibly rising to as much as 4 million ha (10 million acres) by 2020 in USA.

Agricultural residues

• Conversion of Waste product into By-product.• Amount of crop residues amounted to about 3.5 to 4

billion tones annually.• An energy content representing 65 EJ, or 1.5 billion tones

oil equivalent. • Over 2 billion tones of agricultural residues were burned

annually world-wide, producing 1.1 to 1.7 billion tones/yr of CO2.

• The most promising residues from the sugar cane, pulp and paper, and sawmill industrial sectors.

• Estimates are that about 1200 TWh/yr of electricity can be produced from this source.

Bio-energy: End Products

• Biomass-fired electric power plants/CHP.

• Liquid fuels e.g. bio-ethanol and bio-diesel

• Biogas

• Producer gas

• Production of methanol and hydrogen from biomass.
