The aim of this study was to determine the possibility of using residual forest biomass as a renewable energy source based on the analysis and evaluation of the efficiency of production. The object of the research was Ostrowiec Świętokrzyski Forest Inspectorate, in the Świętokrzyskie voivodeship, with an area of 17266.32 hectares. The study included area in exploit and pre-exploit stages, based on stock take data management plan for the years 2004-2013 of this inspectorate. The richness was established, i.e. the volume of forest stands, wood thickness (thickness of the timber), expressed in m3/ha and the annual volume increment and the average age of forest stands. The estimated realizable amount of woody biomass from forest and wood resources for energy purposes has been specified. Logging indicator for economic purposes was set at 70% growth, and for energy purposes – 25%. Waste wood resources (edgings, sawdust, chips, shavings, etc.) were assessed on the basis of logging for industrial purposes, including the rate of 20% of the initial intended for processing. Size of annual timber harvest in the analyzed forest inspectorate was set at 90.397 m3, including the use of pre-exploit part at 35,390m3 and 55007 m3of exploit part use. In terms of waste wood resources for energy purposes set including 18,192 t/year, of which 10491 t/y of wood resources in the state forests and 7701t/year from wood processing. Converting it to energy value (18.72 GJ/t) it can be stated that the waste wood from the Ostrowiec Świętokrzyski forestry inspectorate can reach 170277 GJ per year. The resulting volume of energy resources will allow for annual lighting for 13844 people or warming 2936 houses. You can generally say that waste energy resources analyzed forest district should meet the needs of electrical and heating the average rural community.
