In Slovenia wood as an energy source is one of the most important renewable energy sources replacing fossil fuels. In addition to fuelwood, which is mostly used by households, scrap wood, pellets, briquettes and other wood fuels are also important, whichare used also in the wood processing industry for covering own needs for heat and electricity and in district heating systems, is also important.
V Sloveniji se les kot energent uvršča med najpomembnejše obnovljive vire energije, s katerimi nadomeščamo fosilna goriva; poleg okroglega lesa za kurjavo, ki se večinoma porabi v gospodinjstvih, so pomembni še lesni ostanki, peleti, briketiter druga lesna goriva, ki se porabljajo tudi v lesno-predelovalni industriji za pokrivanje lastnih potreb po toploti in električni energiji ter v sistemih daljinskega ogrevanja.
