The energy supply for the convent, the school and the workshops is designed as a solar-hybrid-system.
The electricity for lighting and for the operating of computers and refrigeration is secured by the solar power plant. Only for driving the big 3 phase driven machines, planing machine and welding machine, it becomes necessary to start the generator-set.
The cooling water of the generator-set is used to heat a cistern up. From there, the hot water attains to the washing machines. So, an additional facility to save energy is generated (power-heat-coupling). In order to reduce the costs for fuel, the generator-set can be driven with diesel as well as with pure plant oil. The needed bio-fuel is grown as a hedge on their on fields.
