Willow - Wikipedia, the free encyclopedia

Energy: Willow is grown for biomass or biofuel, in energy forestry systems, as a consequence of its high energy in-energy out ratio, large carbon mitigation potential and fast growth.^[12] Large scale projects to support willow as an energy crop are already at commercial scale in Sweden,^[13] and in other countries, others are being developed through initiatives such as the Willow Biomass Project in the US and the Energy Coppice Project in the UK.^[14] Willow may also be grown to produce Charcoal.

But I should add that I am not up to speed on the Salix-debate.
