The paper presents the fuel usage and heating energy efficiency of forest district offices in Poland. This analysis of fuel and energy consumption deals with 197 forest districts, that is 45% of all such forest administrative units in Poland. The results show that almost half (45%) of forest district offices are heated with natural gas or oil. Wood as the only source of heat is used in 18% of forest districts and a similar percentage of forest districts use wood with coal for the production of heat. A quantitative analysis of fuel usage shows that 60% of all the consumed heat comes from wood, whereas a mere 13.12 and 16% comes from oil, gas and coal respectively. Thus oil and gas heating systems prove to be the most energy saving. The forest districts heated with those fuels show the lowest average energy consumption. Up to 52% of heating costs in all the analysed forest districts are fuel costs, while 36% of the total heating costs are running costs. The fact that 60% of all the energy consumed derives from wood combustion, while less than 40% of forest districts use wood for heating purposes, proves that the wood fuelled installations that are used in forest districts are ineffective.
