ENERGY ALTERNATIVES

  Ssaving  of  about  42% in the  quantity of fuel is  possible, 
  switching over to IC's from TC's.

  Case I:   taking  dung  yield  for  cattle as 3 kg/animal/day, 
            for buffaloe 12 kg/animal/day.Per capita requirement 
            of biogas as 0.34 m3/day. Table 3a lists, percentage 
            population domestic energy requirement can be met by 
            biogas option.
            Kolar taluk data  shows  that in 132 villages biogas 
            can meet energy demand of  15% of population. In 130 
            villages  biogas  potential  is  sufficient  to meet 
            15-30%  of  population's energy  requirements. In 30 
            villages  Biogas can meet energy demand of more than 
            45% of village population.
  Case II:  taking dung yield for cattle as 3 kg/animal/day, for 
            buffaloe 12 kg/animal/day. Per capita requirement of 
            biogas  as  0.43 m3/day.  Results  are  tabulated in 
            Table 3.2.
            This  shows  that  in  171  villages biogas can meet 
            energy demand of  15% of population. In 137 villages 
            biogas  potential  is  sufficient  to meet 15-30% of 
            population's energy requirements.  
  Case III: taking  dung  yield  for cattle as 7.5 kg/animal/day, 
            for buffaloe 15 kg/animal/day.Per capita requirement 
            of biogas as  0.34 m3/day.  Results are tabulated in 
            Table 3.3.
            This  shows  that  in  Kolar  116  villages can meet 
            domestic  energy  requirement  of  more  than 45% of 
            population,  In  84  villages  potential can meet 30 - 
            45% of population. 
  Case IV:  taking  dung  yield  for cattle as 7.5 kg/animal/day, 
            for buffaloe 15 kg/animal/day.Per capita requirement 
            of biogas as  0.43 m3/day. Results  are tabulated in 
            Table 3.4.
            This  shows  that  in  99  villages  of  Kolar taluk, 
            biogas can meet energy  demand of  15% of population. 
            In  112  villages  biogas potential is sufficient to 
            meet  15-30%  of  population's  energy  requirements.  
            30-45%  of population  energy requirements is met in 
            86  villages  by switching over to biogas.  About 65 
            villages have potential which can meet more than 45% 
            of population requirements.
