Publications of the Central Statistical Office categorize biomass into solid biomass, bio-fuel, and biogas. The present article summarizes the acquisition of solid biomass in Poland in the years 2002–2011. During this period, there was a 70% increase in the share of biomass in energy production, particularly since 2008. The article also presents the use of landfill gas and biogas from wastewater treatment plants in Poland for the years 2002–2011. In 2011, the share of the total biogas has more than quadrupled compared to the base year of 2002. The third group considered consists of bio-fuels. In 2011, the consumption of bioethanol was only 14.5% higher than in 2002, while the share of biodiesel in the energy balance during the same period increased fourfold. The increased use of biomass for energy purposes is primarily due to its low price. Though presently commonplace, environmentally harmful coal is increasingly being replaced by straw, which is approximately four times cheaper to use. In landfills where biogas is formed, in accordance with the recommendations of the European Union this energy source should be recognized and used energetically. It is estimated that – based on the quantity and calorific value, method of management, available technology, as well as the market prices of heat and electricity – the time of return on investment for the installation of degassing systems is from 2 to 10 years. Increased use of bio-fuels is anticipated due to the fact that they have already seen a growing presence as a fuel additive sold on the Polish market (up 7.1% from 2013). At some fueling stations, it is already possible to buy pure biodiesel, the price of which is lower than that of conventional diesel.
