1. Introduction
Besides minimising or avoiding the utilisation of fossil energy
carriers, the enhanced use of renewable energy sources is considered
to contribute highly to the reduction of the worldwide
CO2 emissions into the atmosphere and to the protection of fossil resources (Wisniewski et al., 1993; Hall, 1997). Comparing
various options of bioenergy production, it is concluded that
the production and use of woody biomass for energy transformation
purposes entails numerous beneficial impacts, such
as job creation and further positive implications for the added
value at regional scales (Hall, 1997; Muschler and Bonnemann
