Renewable energy resources represent a new opportunity in Romania, with less participation in the market than those forums outside of the country borders, but with developing perspectives in the future. In present in Romania it doesn’t exist a very well established renewable resources industry, but only small scale projects or developing pilot projects of some developing institutes or small companies could be mentioned. Energy renewable resources capitalization could contribute to achieve some strategic objectives regarding increasing security of energy supplying by diversifying energy resources and reducing of imports, and for a sustainable developing of energetic sector and environment protection. Renewable energy resources from biomass could be o good solution for heating in rural zones. Biomass potential in Romania is expecting to increase in 2005-2010 trough reforestations with various trees species and short term re-afforestation. In this paper the advantages of using biomass for energetical purposes and the technological level achieved by conversion processes of biomass in energetical products are presented.
