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
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
