Principles and criteria of sustainable bio-energy production
The welfare of the modern society relies extensively on fossil fuels. Despite economic and environmental problems and the exhaustion of fossil fuels, the current energy models are characterized by the vast use of fossil fuels and by the dependency ratio of the “inevitable energy import”, necessary to meet the internal energy consumption demands of most industrialized countries. During the recent years the international and national policies have changed. They are oriented towards the extension and optimization of using renewable resources, through the rational use of local resources.
The influence of climate changes, increasing energy demands, unstable oil prices and energy poverty have led towards research of other alternative cost-effective energy resources, socially acceptable and ecologically sound. The production and use of bioenergy is one of the significant mounting alternatives.
