As observed from Table 8, net energy gain (15.56 MJ)
is found to be very high compared to Jatropha system (i.e.
1,887 kJ = 0.1887 MJ) analyzed by Wouter et.al 2009.
This may be due to consideration of pod shell and wood.
Addition of Honey and green biomass as out put will
increase net energy gain considerably. Net energy ratio
is found to be very high as well (i.e. 24.74 MJ), which is
very encouraging for recommending Pongamia as a
promising biodiesel feed stock
Net energy gain is the energy available after total
energy output is deducted from total energy input.Net
energy ratio is the ratio of total energy output to total
energy input.
In the study where the system is expanded to include
a biogas installation (Table 6), the NEG decreases to
14.91 MJ/FU and the NER to 23.76 MJ followed by
further decrease in NEG to 14.76 MJ and NER to
23.52 MJ if biogas is employed for electricity generation
