An important challenge in the twenty-first century is to supply the growing world population that requires more and more energy per person with sufficient energy. Today, this energy supply is mainly based on fossil energy carriers that have large drawbacks, like the impact on climate change and the depletion of the resources. 

Bioenergy is the production of renewable energy from organic material. It corresponds to three main feedstock categories (agriculture, forestry & waste) for three main uses (transport, heat & electricity). The development of bioenergy is often retained as a positive option due to its contribution to the mitigation of climate change, agricultural and rural development, energy security, innovation policies.
