The aim of the paper is to analyse and assess the use of renewable energy sources in the Polish energy balance for the period 2006-2010. In Poland, in according to the Energy Law (1997), renewable energy sources are sources using the processing power: wind energy, solar radiation, geothermal energy, waves power, energy of currents and tides, energy of river gradient, biogas and biomass. Biomass could be divided into forest biomass, agricultural biomass (mainly energy crops, but also consumer waste from the agro-industrial production) and biomass originating from industrial and municipal organic waste (Jasiulewicz 2010).
