existing and potential development; technological advances and knowledge
which have recently accumulated on many aspects ofbiomass energy.


Recently launched, national energy program BIOEN (Biomass and Waste
Use Program) has the aim of providing permanent care for the use ofbiomass
and waste for energy production and environment protection. The Program
has a long - term character and will be based on the positive experiences of inland
experts and of those European Union countries that have realised similar
programs with success. This program plans to use wood waste, straw, agricultural
crops, crop residues, animal waste, municipal waste and other primary
biomass sources as well as processed biomass like liquid (biodiesel, ethanol,
methanol) and gaseous (biogas, methane) fuels for energy production, traffic
purposes or as a base in chemical industry.


The Energy Strategy of the Republic of Croatia has considered three different
scenarios. First of them (SI, "low ") was based on slow introduction of
advanced technologies and does not include any governmental support. Second
scenario (S2, "moderate ") includes stronger concerted policy for introduction
of new technologies, use ofrenewables and increasing energy efficiency.
Finally, third scenario (S3, "high ") is "very environmental" scenario and
comprises that problem with pollution and greenhouse effects will significantly
affect energy policy in Croatia already in 2010. All scenarios have the same
rate of economical growth, economy structure and number of consumers, but
not the same consumption rate. The main differences are in level of governmental
support, which influence the use ofrenewables, dynamics of advanced
technologies penetration and care for energy efficiency. Unlike other renewables,
bioenergy has significant position in all scenarios. This is due to long
tradition and experience ofbiomass use in Croatia as well as large biomass
potential. The principal parameters of the scenarios related to biomass use
are: current and additional biomass resources, potential user sectors, assessment
of the energy demand, and assumption on the type of energies per sector
abandoned in favour of bioenergy. The scenarios differ most significantly in
the structure of different technologies for biomass utilisation, in the electricity
generation from biomass and in the penetration ofbiofuels in transport.


This paper deals with present and future energy production from forestry
biomass (fuel wood, forestry residues and wood waste). Forestry biomass is
recognised as most important source of bioenergy and has significant place in
all analysed scenarios.
