The energy requirement in India is steadily increasing and this requirement
is being met by both commercial and renewable energy sources. Due to the n
on-availability of sufficient resources and a considerable amount of emissi
on of pollutants from commercial energy, it is now being felt that renewabl
e energy has to be utilized to a greater extent. An optimization model was
developed to determine the optimum. allocation of renewable energy in vario
us end-uses in 2020-2021, taking into account commercial energy requirement
; In lighting end-use renewable energy to an extent of 1.27 x 10(15) kJ can
be utilized. Scenarios were developed for various parameters and sensitivi
ty analysis was performed on the model. It was found that for a 3% increase
in social acceptance of bio resources, there was 65% decrease in solar PV
utilization and to that extent bioresources were introduced. Similar analys
is was performed on the model by changing the demand, potential, reliabilit
y, emission and employment factors. The analysis revealed the critical para
meters for the utilization of a renewable energy source. Using the critical
parameters, appropriate policies can be formulated for promoting renewable
energy sources. (C) 2000 Published by Elsevier Science Ltd.
