From the discussion above it is clear that for sustainable
development, it is necessary to increase the magnitude of energy inputs through
increased supplies from renewable sources like solar water heaters, biogas,
gasifier, mini-micro hydro electric plants, energy plantations (on wastelands)
etc and conservation through improved efficiencies of the end use devices like
cook stoves (thus saving of fuel wood), irrigation pumpsets etc.
About 27.72% energy could be saved in Industries sector. Which
means about 1541 million units of electricity could be saved ( as per
electricity statistics Industries sector in Karnataka has consumed about 5560
million units during 1991-92). This saved electricity is equivalent to
electricity output of 300 MW installed capacity of generating stations.
Environmental problems associated with mega projects, the increasing demand of
states/ country and resource depletion make it increasingly imperative that our
planners divert their attention towards improving efficiency in all sectors.
This research illustrates that, there is ample scope to conserve energy in
Cooking is the dominant end use activity. Use of highly
efficient improved cook stoves and biogas would save fuelwood of the order of
20-30%. Water heating for bathing could be done through solar heaters. This
reduces pressure on electrical energy in urban areas (all electric homes) and
fuel wood in rural areas.
Decentralised renewable energy generation systems like community
biogas plant, wood gasifier would provide employment, assured electricity
supply, good drinking water (water pumping), good illumination at home and
streets, revenue to the village and lead to the self reliance of the rural
communities. Involvement of village community in the implementation and
management, technical feasibility, economic viability of the decentralised
system makes the system self sustaining. Renewable resources utilization would
help in preserving the environment, reduces import of non-renewable resources
like coal, oil etc., improves balance of payment and provides better protection
