Biofuels
On land, on water and in the air: Biofuels can be used to drive engines in cars, trucks, ships or even airplanes. Different biofuels are available such as biodiesel, vegetable oil, bioethanol, biogas and in future synthetic biofuels too (so-called BtL - biomass-to-liquid-fuel). Biofuels reduce CO2 emissions in traffic. Biofuels can replace part of global oil petroleum consumption. In Germany they currently (2011) cover 5.4 percent of fuel requirements. In 2011 biofuels avoided 4.8 million tons of greenhouse gas emissions. Biofuels are mainly produced with domestic biomass in Germany: Biodiesel comes from the rape field and not from the rainforest.
Background information
The Full Picture of Renewable Energy
At first glance, many reservations regarding renewable energy sources appear plausible. Yet they often conceal a completely different picture.

Background information
Biofuels – climate protectors cultivated in Germany
Apart from renewable electro-mobility, biofuels are indispensable for energy-efficient transport structures of the future
Background information
Bioenergy is a useful part of crop rotation
Rape can only be grown on the same area every three to four year – a monoculture is therefore excluded.
Background information
Biodiesel saves up to 66% CO2
The climate balance of the various biofuels depends on how energy-intensive the cultivation is and how complicated the transport and conversion are to organise .
