ROC agricultural authorities have encouraged pig farmers to install biomass-powered electric generators since the early 1960s, but investments and generating costs are still too high to make methane a significant energy source in the foreseeable future.
我國早在民國五十多年，農復會曾大力推廣家庭式的沼氣發電，對象是小型養豬戶。後來養豬變成企業經營，動輒十萬頭，養豬戶沒有多餘空間來設置發酵槽。另方面，由於沼氣建造費用、發電成本高，經濟效益不高；而廢液的排放、處理仍然可能造成汙染，因此未能普及。
