1. Abundance of Waste and Energy Scarcity

To underline the importance of the Waste-to-Energy chain proposed in this book, the motivation for exploitation of waste for energy purposes using fuel cells will be set out according to a point-by-point discussion. By reviewing the nature and availability of the world’s energy sources and by analyzing the implications of their utilization, the critical prospects of future energy supply will emerge. Simultaneously, the status and consequences are set out of a society centred on production and economic growth in terms of waste accumulation and harmful emissions. The combined picture brings to the fore that a double-edged solution can be achieved by a more extensive utilization of above all organic waste for conversion to clean, efficient energy. This principle implies and supports also a less centralized energy infrastructure, for the benefit of local productivity and an increased sense of shared responsibility.
