Presentation onRenewable Energy Technology and Green Economy Presented By: Dr Rhiddi Bir Singh Professor & Head Natural Resources & Products Development, Research Centre for Applied Science & Technology, Tribhuvan University, Kirtipur, Kathmandu, Nepal Organized By Asia Pacific Graduates Youth Forum on Green Energy The Small Earth Nepal (SEN)
- 2. Renewable Energy Resourcesand Technology The Renewable Energy Resources are not well defined. Renewable Energy Technologies are still to be defined with reference to the Bio- mass energy technology.
- 3. Current Energy Situation In NepalEnergy sector is next to the food commodity in the general public life.Energy Resources Consumption in Nepal 2009.Total Energy Consumed 400.5064 million GJ 100.00 %Traditional Fuel 348.8694 million GJ 87.09 %Commercial Fuel 48.9023 million GJ 12.18 %Renewable Fuel 2.7347 million GJ 0.68 %
- 4. Total Energy Generated from theRenewable Resources 2009Nepal is survived by the renewable energy resources- mostly by biomass fuels.Traditional Biomass Fuels 348.8694 million GJ 84.98 %Electricity 8.1372 million GJ 2.03 %Renewable Fuels 2.7347 million GJ 0.68 % 359.7413 million GJ 87.69 %
- 5. Total Energy Generated from theNon-renewable Resources 2009Petroleum Products 33.0136 M GJ 9.82 %Coal 7.7515 M GJ 2.53 % 40.7651 M GJ 11.35 %
- 6. Necessity of Energy demand supply is round the clock.Major Energy Issue in Nepal is :Biomass Fuels vs. Rest of the Fuels
- 7. Contribution of Biomass BasedFuels in NepalWood Fuels and Forest Residues 311.1673 million GJ 77.69 %Agricultural Residues 14.4847 million TOE 3.66 %Cattle Dung 23.0174 million GJ 5.74 %Biogas 2.5931 million GJ 0.64 % 351.4525 million GJ 87.73 %
- 8. Contribution of non Bio-mass based fuels in NepalPetroleum Products 33.0136 million GJ 8.21 %Coal 7.7515 million GJ 1.93 %Electricity 8.1372 million GJ 2.03 %Micro-hydro & Solar 0.1416 million GJ 0.03 % 49.0439 million GJ 12.20 %

- 10. Energy System in NepalThe energy generation / consumptionsystem cannot be distinguished into The Urban Energy System The Rural Energy System
- 11. The national energy consumption figure aregrossly classified under Residential Transportation Industrial Commercial Agricultural Sectors
- 12. Energy Data BaseRational energy data base considerationunder the rural / urban energy system is still to be worked out for - Rural / Urban Energy Supply - Renewable Energy System - Energy Economics
- 13. Rural Urban Status of theNation About 83 % of the Nations total Population Reside under the Rural Infrastructure spread over the 3915 Village Development Committees. Only 17 % of the Population are Distributed Under the Urban Area. With in 58 Municipalties.
- 14. Rural Renewable EnergyTechnologies in NepalRecognized, Developed and Implemented RETsare Limited Under # The Physical Energy Resources Micro Hydro Power Solar Power # The Biomass Energy Resources Biogas (Dung Gas)
- 15. Energy Resources Harnessed,Developed and Utilized in Nepal Biomass Resources (Traditional fuels ) Wood fuel Cattle dung Agricultural residues Commercial fuels Petroleum products Coal Electricity
- 16. The current status of renewableenergy in Nepal Renewable fuels Bio gas Micro hydro Solar PV
- 17. Energy Resources Still to beDeveloped and Utilized Wind power Geothermal power Liquid Bio-fuels Other Non Dung Based Biogas
- 18. Renewable biofuel resources processedout of selective biomass type Biobriquette ( Solid fuel ) Densified biomass briquette ( Non carbonized ) Carbonized biomass briquette. Biofuels ( Liquid fuel ) Bio-hydrocarbon oil: to be promoted for the substitution of Kerosene oil. Bio-ethanol: to be promoted for the substitution of Motor Spirit ( Petrol ) Bio-diesel: to be promoted for the substitution of High Speed Diesel.
- 19. Biogas Generation Required Biogas ( Gaseous fuel ) Residential waste biogas Night Soil based biogas Agro-forestry waste biogas Land fill biogas Rural waste / Sewerage biogas Industrial Biogas
- 20. Green Energy Technology Biomass fed power plant for electricity generation. Biomass gasification: Thermo-chemical conversion for electricity as well as for thermal applications. Biomass gasification: Bio-chemical Conversion for thermal as well as the electricity generation.
- 21. Limitations of Current Movement of RenewableEnergy Technologies under the Alternative EnergyDevelopment and Promotion. There is no separate identified government institution devoted to research, development and innovation regarding the renewable energy technologies. Only dung gas plant, micro-hydro power and solar power system are in the implementation phase. The primary motivational theme of these RETs is basically meant for residential supply of the energy generated.
- 22. Insignificantly minor enterprise may have entered into the income generation activity very limitedly within the scarce surplus energy resource in the rural arena. It is still largely unattended to assess, evaluate and provide rationally conclusive remarks on
