Ethanol wird durch Vergärung von in Pflanzen enthaltenen Zuckern gewonnen. Grundsätzlich eignen sich zucker-, stärke- und cellulosehaltige Pflanzen. Biodiesel bleibt mit ca. 2,0 Mio. Tonnen der wichtigste Biokraftstoff in Deutschland. Er wird als Reinkraftstoff und vor allem über die Beimischung zu normalem. Biomass should the environment, the climate and nature conservation in the interest so manufactured that their use for energy production causes at least 35 per.

Biokraftstofce, the enhancement of the greenhouse effect caused by emissions of carbon dioxide and other greenhouse gases through the burning of fossil fuels causing global warming may change climate and living conditions on Earth.
Biofuels contribute to climate protection releasing only the amount of carbon dioxide during the combustion process which was previously fixed in the plants. Therefore it is important to use existing resources carefully and to search for new alternatives.
Biokraftstpffe if their Niokraftstoffe balance is not completely neutral due to the manufacturing process, they are able to contribute to significant reductions in the greenhouse gas emissions of the transport sector. The scarcity of fossil oil is no new concern. As already mentioned biofuels contribute to significant reductions in the greenhouse gas emissions in the transport sector releasing only the amount of carbon dioxide during the combustion process which was previously fixed in the plants.

Resource efficiency and climate protection Today, the mobility of our society is mainly ensured by fossil fuels, especially crude oil whose reserves are limited. Even though nobody can predict exactly when those reserves will be depleted, experts agree about the fact that due to the rising global demand cheap oil is scarce.
It is therefore undisputed that we need alternatives to fossil fuels.
While the market shares of renewable energies in the heat and electricity sector by now became significant, fuels are still gained almost entirely from fossil resources.

Therefore they can slowdown climate change. Bioenergy in Germany – Facts and Figures Apart from biomethane, which is chemically identical to natural gas, biofuels are liquid and therefore easy to store and distributed through the existing network of filling stations.
There are different types of biofuels like biodiesel, rapeseed oil, ethanol, or methane from biogas currently available on the market. They have a similar high energy density as conventional fuels and do not limit the usual cruising radius. Plant materials offer the only technically proven and quickly implementable option to substitute fossil fuels in the transport sector. What are biofuels needed for?
Despite all, a totally self-contained biofuel supply will hardly be possible in the densely populated countries of Central Europe.

For those reasons biofuels make up today about 5. Biofuels from waste, residues, wood and other renewable resources offer conceivable alternatives and will continue to contribute significantly to a sustainable mobility. Today, the mobility of our society is mainly ensured by fossil fuels, especially crude oil whose reserves are limited.
