Potential based on Schrattenholzer and Fischer, IIASA, 2000 2.) Based on IEA: Key energy statistics, 2006 (TPES), EIA (US) projections for 2030 are 684 EJ, 721 Q (BTU 1 British thermal unit (Btu) = 1,055.05585262 joules (J)) 3.) Derived from http://www.earth-policy.org/Updates/2005/Update49.htm, Earth Policy Institute 4.) Assuming an average yield per hectare for ethanol of 4200 l (3000 l US maize, 5500 l Brazil cane, 6900 l France sugar beet) and of 3800 l/ha for biodiesel (average). Most recent yields are about 10% higher for cane and 20% higher for maize. 5.) 850 million ha would be required to meet 2002 road transportation fuels needs (77 EJ) at current yields (l biofuel/ha), technology, and crop composition. 6.) Area for developing and developed countries, not OECD and non OECD 7.) Assuming an energy content of 34 MJ/l for biodiesel and 21.1 MJ/l for ethanol 8.) Bruinsma (ed), World agriculture: towards 2015/2030, An FAO Perspective, 2003, total suitable land for rainfed agriculture 9.)

Based on regional estimates from Schrattenholzer and Fischer, IIASA, 2000 13) The IEA Energy Outlook 2006 assumes a 4% share in road transportation in 2030 in the reference case, 7% in the alternative scenario Wie groß ist der Markt für Biomasse und Biotreibstoffe?

33 33 Determinants of Bioenergy Production Population growth and economic development Energy prices Food consumption: per capita calorie intake and composition of diet Land use patterns (feasibility of marginal/degraded lands) Efficiency of food production: crop yields, livestock production Forest productivity and sustainable harvest levels. Competing demands for land: nature reserves, endangered/protected ecosystems, recreation, amenity Competing demands for wood and agriculture based bio- materials.
