coordination and cooperation in stakeholders are missing. While
High capital cost coupled with smaller capacity and less efficient
models of biogas plants make them less acceptable. And Participation
is restricted due to fewer demonstration units, very low
motivation and less promotional activities [35]. Research studies
showed that efficiency of biogas plants are being under utilized
many of the farmers do not follow the recommended practices. A
study shows that in Nepal 67.5% of plants observed received optimum
water-feces ratio while 5% plants were being fed with lesser
quantities of water and 27.5% units were fed with more than prescribed
water quantities. This clearly reveals the fact that sufficient
training is lacking on account of running such units [32]. Similar is
the case with other developing countries, i.e. an Indian study has
indicated that there is potential of almost 25,700 MW electricity
generation from biomass but the actual production till 2007 was
just 1227 MW that is just 4.47% of total potential [15]. Apart from
these, maintenance services are less common and not easily accessible;
gas leakage and low pressure are also factors responsible.
Varieties of reasons make renewable energy resources less competitive
as compared to conventional fossil fuels. So the government
support is needed to make the alternative energy sources popular
[35].
