The paper presents an analysis of the potential possibility of using ash-leaved maple Acer negundo L. as an energy plant. The description of this species, originating from Northern and Central America and introduced in Poland in the 17th century, was carried out. It showed that the analysed species fulfils the basic requirements for energy plants. This means that ash-leaved maple Acer negundo L. has large annual stand increment and high disease and pest resistance as well as low habitant requirements. Basing on the biological features of the species, the conditions of minimum negative influence on the natural environment was qualified. This individual attribute prevents generative and vegetative reproduction and species „escape” from the plantation. The basic physical proprieties of the maple biomass were analysed in comparison to the willow biomass properties. The results of the comparative analysis show that the calorific value as well as the yield and proper density are comparable, however the ash-leaved maple cutting resistances has significantly lower values.
