This results in environmental as well as climate change problems. Renewable energies offer many opportunities to overcome these problems – they can provide heat and electricity as well as automotive fuels in environmentally friendly systems and thus contribute to lower the fossil fuels dependency. Biomass as the oldest renewable energy of mankind is still playing a dominant role as an energy carrier in some African and Asian regions, where biofuels are still used in traditional ways – mainly for cooking. On the other hand biomass has a huge potential to become a more important energy resource even in industrialized countries. All over the world the opportunities of biomass are accepted and biomass has become a common term in politics resulting in new strategic analyses, political documents, legislative actions and funding programs. A lot of modern and new high-tech solutions for bioenergy systems are already developed and others are under research. Aims of the actual developments are new bioenergy systems on the basis of regional biomass potentials in rural regions. The Baltic Sea Region offers a high potential to produce biofuels for different applications to fit the growing demand of heat, electricity and fuels. In combination with its industry and engineering skills the Baltic Sea Region is predestinated as a nucleus for further development and demonstration of advanced bioenergy solutions. In the result of the conference “Contribution of Agriculture to Energy Production“, held in Tallinn, Estonia in October 2005 representatives from policy, economy and science identified a high potential and demand for bioenergy solutions and realized the necessity of establishment of an international network (Baltic Bioenergy Net – BaBEt) for information and know-how transfer between the Baltic States to foster the energetic use of biomass. Further activities to establish a Baltic Bioenergy Net lead to this follow-up conference, renamed as 2nd International Baltic Bioenergy Conference, held in the medieval world heritage Hanseatic town Stralsund, Germany, 3 Nov. 2006. This 6 Use of Bioenergy in the Baltic Sea Region - Proceedings of the 2nd IBBC 2006, Stralsund, Germany 2IBBC under patronage of the Minister of Food, Agriculture, Forestry and Fisheries Mecklenburg-Vorpommern is funded by Deutsche Bundesstiftung Umwelt. Aim of the conference is information and know-how transfer between Baltic Sea states as well as international partners in the field of bioenergy technologies. Plenary presentations will focus on the actual situation of bioenergy in the European Community and selected countries and areas. In three workshops the specific situation in the field of solid and liquid biofuels and biogas is presented and discussed and completed by excursions. Furthermore the representatives of all Baltic states are invited to sign a letter of intend as the next step to create the Baltic Bioenergy Net as the future basis for closer contacts and intensive cooperation in research and demonstration projects in order to achieve a
