The use of biofuels grew strongly in Germany between 2004 and 2007, but its share has been stagnating since then, at between 5.5-6%. Biodiesel made from rape led the way, ahead of ethanol made from grain - both 1st generation biofuels. Biofuels have significant long-term potential in Germany - by 2030, domestic biofuels could cover 20% of fuel needs, and a good 70% by 2050. In the EU too, biomass compliant with sustainability criteria could in the long-term cover around a third of energy needs. Globally, Brazil and the USA dominate the biofuel markets, with bioethanol as the leading product. Worldwide, residues and degraded areas alone represent a bioenergy potential of 100 to 200 exajoules, which in the long-term could cover all liquid fuel needs. The trade of bioenergy is increasing throughout the world, because the availability of and the demand for biomass, bioenergy and biofuels vary from one region to another...

...The increasing use of bioenergy can give rise to competing uses. Globally, the use of agricultural biomass for feed (74%) is in the lead, followed by food (18%), and then for energy and as a material at around 4% each. The competition between fuel and food is given most attention. Biofuels can contribute to price increases and fluctuations for agricultural products; they can, however, also create employment and income. Of even greater importance for food security is the increasing demand for foodstuff. Worldwide, at the moment, 1% of agricultural land is used for modern bioenergy; in Germany the figure is 6.8% for biofuels, and 5.7% for biogas. Other competing uses arise with regard to the use of the material - for solid biomass (wood), and in the future, for bio-refineries, synthetic biosubstances, and similar. Competing uses are also emerging between different sectors that use them (power, heat, transport), as well as within the transport sector. They may - at least partially - be resolved through regulation of the rights of use and exploitation...

...In order for there to be a (bio) energy transition in the transport sector, existing, sustainable biomass potential must be used as effectively as possible. Comprehensive greenhouse-gas balances and applying the same standards for all bioenergy carriers shall improve the competitiveness of the 2nd generation. In addition, a European market introduction programme for them should be set up to run for 10 years, neutral and oben to new technologies. Strategic investments must be made both in the production of 2nd generation biofuels, and in cultivating the raw materials needed. To increase the acceptance of biofuels, we need biofuels and automotive technology coordinated optimally, or drop-in fuels, as well as increased transparency with regard to the provenance of biomass and biofuels...
