The paper presents a general description of the need to use wooden biomass resulted from Osier willow and beech. This wooden
biomass represents a renewable energy source and some new directions in scientific research field could be opened. The paper
mainly describes a parallel between the energy resulted from these two types of biomass, namely from Salix viminalis L. and
Fagus sylvatica L. species, in order to obtain the best solution between them. Growth crop of this new specie of Osier salix can
become a business in the developing countries as Romania. In the extended way there are mentioned some characteristic of these
two kind of plants that grows in Romania which direct influence the energetic power. Finally, based on the differences between
the two types of species and woody biomass, the best solution is found in favor of energetic willow
