  1. Workshop on the Economic and Environmental Impacts of Bio-Based Production Global biomass energy potential Jose Roberto Moreira Brazilian National Reference Center on Biomass Chicago, Illinois, Usa June 8-9, 2004

  2. PRESENTATION CONTENT • Available Evaluations of Global Biomass Potential • Sugarcane Crops as a Source of Energy for Today • Sugarcane Crops as a Source of Energy for Tomorrow • Potential Energy Availability – A Scenario for Sugarcane Large Plantation Effort • Physical Results • Economic Results • Carbon Sequestration Potential

  18. FUTURE SCENARIO FOR ENERGY FROM SUGARCANE • MODEL ASSUMPTIONS • TIME PERIOD 2003-2030 • TOTAL PLANTED AREA BY 2030 • 143 MHA DISTRIBUTED OVER TROPICAL COUNTRIES • ACHIEVABLE YIELD BY 2030 140 t/ha/yr

  19. Planted area growth equal or less than 8%/yr Yield Growth = 3%/yr up to 140 t/ha/yr Electricity production = 50 to 500 kWh/tcane Ethanol production = 90 to 114 l/tcane

  20. SECONDARY ENERGY CATEGORY PRIMARY ENERGY (EJ/yr) SECONDARY ENERGY (EJ/yr) TOTAL LAND AREA USED FOR CROPS ELECTRICITY 94.1 37.9 LIQUID FUEL 69.9 51.5 TOTAL 163.9 89.5 1.41 X 106 km2 Amount of energy produced from sugar/alcohol mills distributed over world agricultural land area at a density of 1 every 6,200km2 –BIG, Combined Cycle, and 40% more yield Total number of renewable energy producing units is 4,000
