Knowledge regarding wood energy, clean technology (cleantech) and its applications are not sufficiently distributed to the stakeholders of energy production in all regions of the Central Baltic region. The industrial content of cleantech has developed and there is substantial interest in applying these new techniques. The transfer to a greener society must, to a great extent, be built on local and regional initiatives. The Woodenergy project promotes wood as an energy source and improves the knowledge about wood energy, environmental friendly techniques and cleantech with its applications. The project develops regional action plans and strategies on how to promote the effectiveness of wood energy. Case studies are carried out on investment calculations and procurements-related procedures in district heating. Furthermore, the project is developing and introducing a flexible energy system combining wood with other materials such as waste and straw. The project is resulting in a higher level of skill by transnational knowledge exchange in district heating as well as in forest utilisation.
