This study aimed to perform an energy evaluation of Bambusa vulgaris ex JC Wendl. var. vulgaris for ages 1, 2 and 3 years old. Samples from the positions along the stem (base, middle and top) were collected in commercial plantation, managed for energy production. The content of volatile material, ash and fixed carbon, high heat combustion, basic density and energy density, content of extract, holocelulose and the total lignin of B. vulgaris were determined. The results indicate that the age of 1 to 3 years old showed increased ash content, basic density and energy density, reduction of volatile material, fixed carbon content and heat combustion. And also indicate increased ash content, basic density and energy density; decreased volatile material, fixed carbon content and heat combustion from base to top. Considering the energy density as the best, we can say that the quality of Bambusa vulgaris biomass as energy input improves with increasing age and the upper portions of the stemsproduce more energy per unit volume.
