Les avancées majeures dans le domaine des

biocarburants Fuels from biomass : the prospect

Jean-Luc DUPLAN

Fuels : worldwide consumption

World Ethanol Production in 2010 : 42.3 Mtep (~90 % USA and Brazil) World Biodiesel Production in 2010 : 14.7 Mtep (~70 % Europe)

Worldwide energy consumption in the road transport sector in 2010

In 2010, the worldwide road transport sector :

• was dependent on oil at 94%

• represents 50 % of the crude oil primary consumption

• represents about 20 % of the final energy consumption
