The biofuels made of bio-materials have no adverse environmental impact. In terms of the raw material energy characteristics the biomass from energy crops is similar to the classic fuel wood. The biofuels produce more ash and some chemical elements but this fact does not diminish their important role as fuels of good prospects. From an energy point of view the biofuels have net calorific value of about 16-17 MJ·kgE-1 and their emissions are usually within the values allowed by relevant standards. This article refers to testing several interesting energy crop energy potential. The experiments aimed at determination of calorific values of plant raw materials were conducted by using the calorimeter MS-10A LAGET in accordance with the European standards. As the result the main factors affecting the calorific value of any plant raw material were chosen; they particularly are as follows: chemical composition and moisture content.
