Introduction to bioenergy
As a consequence of gro-political instability during the 1970, the oil prices suffered a drastic increase in price resulting in a global energy crisis that developed along the following years. As a results, many countries established new energy policies oriented towards the diversification of energy sources. Among those, the use of biomass for energy became a target, especially in Finland and Sweden, countries with large forest resources, giving birth to modern bioenergy in the area. Nowadays, both countries are leaders in bioenergy development and implementation. This session aims at reviewing the development of modern bioenergy, linking to previous courses, including some of the main factors contributing to its successful implementation.
The modern concept of bioenergy [video]. Bioenergy is the utilization of biomass resources for the production of energy. As such, it is perhaps the oldest technology ever used for energy. What is new then? What are the differences between using wood for energy in the past and nowadays? This video presents my views on bioenergy, and why it is more than the mere utilization of wood to produce energy.
Energy from the Forest - Benefits for the Local Economy [video] This is a video summary of this theme of the course, and shows the different steps to produce biomass from the forests till the power plant. The video is shot in a small municipality in Finland, that has established a district heating plant to produce bioenergy. In Finland local bioenergy operators have combined forces in the harvesting and utilization of energy wood. Eno Energy Cooperative manages the entire production chain from harvesting to wood chipping, transportation, and heating plant operations which has resulted in many benefits for the local economy.

Welcome to the Forest Capital of Europe [video] The video introduces Finland and the city of Joensuu, located in North Karelia, hosting the European Forest Institute, the University of Eastern Finland, the former Finnish Forest Research Institute (METLA, now LUKE), the North-Karelian University of Applied Sciences, among others. Industrially, there is the main factory of John Deere of forest machinery, one of the largests in Europe.

From the video, Energy from the forest- Benefits for the local economy identify the main sources of biomass for energy currently used in Finland.
