It the last 8 years we made serious efforts to use environment friendly and power efficient systems and contribute to their spreading.
As an example:
- water-heating with solar-collectors
- heating and cooling with heat pump systems
- utilization of biomass (vegetal or animal)
- biogas systems
- utilization of thermal-water
- utilization of geothermal power
- production of electric power by solar cells
- desalination
- passive-house systems
