Benefit: Bioenergy harvest and energy production
The use of wood chips for energy production has increased rapidly during the 2000s. Approximately one third of the harvested wood chips consist of logging residues such as the tops and branches of cut trees. 47% of the energy wood consists of small-sized trees, the by-products of thinnings in young forests. The share of small-sized trees has grown notably since 2000. Stumps and roots cover 14% of all energy wood. In 2012 wood chips were used in energy plants and private households altogether 7.6 million cubic meters. That is ten-fold compared to the year 2000.
Consumption of wood-based energy has more than doubled since the beginning of the 1980s. In 2012 the consumption of wood-based energy was 331 petajoules. Also the relative consumption has increased. In 1980 wood-based energy covered 15% of the total energy consumption, and in 2012 the same share was 24%.
The information on the size of the reed canary grass yields has been gathered since 2011. In 2011 the yield was 45.3 million kg and has been decreasing since. In 2013 the yield was only 21 million kg. The area under reed canary grass cultivation was at its highest in 2007 and probably the total yields also peaked around the mid-2000s.
