Project - development summary Best practice in international project examples -Every region needs it s own specific and systematic project development -Decentralized systems can offer high added value, new jobs and sustainable development -Bioenergy is a storable source for base- Bioenergy is a storable source for base and peakload demand and is easy to combine with other renewable energy
Example for hybrid systems: -geothermic energy for baseload combined with -stored biomass for peakload Geothermic heat and power generation without using ground water resources
