Wood chips
The school build­ing and the farm­house on the Schluechthof are heated by means of chip heat­ing. There is a plant with a ca­pac­ity of 180 kilo­watts (KW) avail­able. With ap­prox. 650 m3 of wood, a total of 220,000 kWh of heat en­ergy is pro­duced each year.

Solar Power Sys­tem
At the Schluechthof and Chamau sites, a pho­to­voltaic sys­tem of 30 kW each is in­stalled, which con­verts solar en­ergy into elec­tric­ity. To­gether, they pro­duce 60,000 KWh, which would sup­ply about 20 single-​family homes per year. The elec­tric­ity pro­duced is needed di­rectly at the same lo­ca­tion.

Bio­gas
The basic nu­tri­ent Bieag.ch in Hünenberg con­sists of ma­nure, which comes from the sur­round­ing farm­ers. The ma­nure is pumped through an un­der­ground pipe sys­tem di­rectly from the farmer to the bio­gas plant and back again. Also, the Chamau con­nected on this pipe net­work. The plant pro­duces 3,440,000 kWh of en­ergy in the form of heat and 2,817,000 kWh of elec­tric­ity in the form of elec­tric­ity each year. To­gether, this en­ergy would suf­fice for one year for 2,085 single-​family homes. The fer­mented sub­strate is sub­se­quently re­turned to the nu­tri­ent cycle as the farm­ers reuse the fer­til­izer. Fur­ther in­for­ma­tion can be found at www.bieag.ch
