Palnitkar solarenergyindependenceasusedinruralindia Presentation Transcript

  • 1. Solar Energy Independence as Used in Rural IndiaGiven: April 27, 2007
  • 2. Overview of Presentation India demographics and need for resources India’s energy profile Why solar? Governmental and Private Initiatives Problems Conclusion
  • 3. India: Land of a Billion Energy Needs 2.4% of land area with 16% of the world’s population Life Expectancy 64.71 years Household sector: largest consumer of energy accounting for 40-50 % of total energy consumption In rural areas, the domestic sector accounts for nearly 80 percent of total energy consumption About two thirds of India’s more than 1 billion people live in rural areas
  • 4. India’s Energy Crisis - Dependence India is currently importing 100 million tons of crude oil Foreign exchange outflow of Rs.1.5 trillion per year (nearly $34 billion) At this rate, in 2030 the country may have to import 300 million tons of crude oil.
  • 5. The President’s Message: Independence Cut down energy losses Utilize technologies to provide a diverse supply of environmentally friendly energy “We must achieve Energy Independence by 2030”, including a cut down in ALL sectors Increase the power generated through renewable energy sources from 5% to 25% President A.P.J. Abdul Kalam This is the nation’s “first and highest priority” (Rocket Scientist)
  • 6. President’s Solar Message Kalam pushes solar as a key part of the 2030 energy independence plan Agricultural sector - both for powering farms and for desalination plants to bring in fresh water Nanotechnology research -- something that India has already embraced -- to a drive to improve solar efficiencies.
  • 7. Two ways to Solar Thermal Energy  Research and development for technologies.  Example: A large solar dish has been set up under a research project at Latur in Maharashtra to provide process heat for milk pasteurization. Photovoltaic Energy
  • 8. Brief Overview of Solar PV Technology Solar cells are made of silicon (microelectronics/semiconductors) Treated to be positive on one side and negative on the other. When light energy hits the cell, electrons are knocked loose from the atoms in the semiconductor material. If electrical conductors are attached to the positive and negative sides, forming an electrical circuit, the electrons can be captured in the form of an electric current.
  • 9. India’s Solar Profile India ranks 3rd in annual production capacity of solar PV ahead of Germany, France and Australia India increasing budget for implementing solar power plants
  • 10. Why is Solar so easy for Rural India?
  • 11. Rural Needs are Simple Fuel for cooking Water for drinking Light for studying Television and telephone for entertainment and connectivity
  • 12. India Has a Lot of Sunlight Sunlight on the surface of earth is the radiation received from sun. India has adequate sunshine available for most parts of the year, including rural areas. The amount of solar energy impacting the surface of earth is 1000 watts per square meter, which is about 32.8 million MW every second on the Indian land mass. *A large part of the incident heat is reflected to the outer space or radiated back to space.
  • 13. Solar: Easy Energy In Rural India Solar energy is practically inexhaustible Widely distributed Environment friendly Cost free in raw form No need to transport raw materials to villages No towers, heavy cabling, etc.
  • 14. Governmental Rural Initiative:Solar Cooking Project Current sources available for cooking are firewood, crop residues and animal dung in rural areas Promoted by the Government of India  Parabolic Dish Solar Cookers  Solar Box Cooker  Community Solar Cooker  Solar Steam Cooking System
  • 15. Private Initiative:Solar Loans from Selco India Customers: poor daily-wage laborers to institutions All buy solar panels at the same rate: about $450 for a 40-watt system that can light several 7-watt bulbs for four hours between charges. Persuaded rural banks to lend hundreds of dollars to rural people
  • 16. Governmental Rural Initiative:Solar Farms 100 MW sized Very Large Scale Solar Photovoltaic (VLSPV) Stations Program to develop efficiency of solar cells from 15% to 50% Make farmers “farm the sun”
  • 17. Private Initiative:Tata Power makes life Solar Sunbank, a customized package for rural banks Coming soon : ATMs Suraksha, a solar-powered communication system, helps police stations function effectively
  • 18. Private Initiative:Tata Power contd. Solar powered vaccine refrigerator manufactured indigenously by the company and approved by the World Health Organization (WHO). Low cost solar lantern
  • 19. Private Initiative:Tata Power contd. Currently powering houses, schools, police stations, etc. My Uncle’s House – powered by solar
  • 20. Disadvantages of Solar Energy for RuralIndia Low intensity or dispersion Its unpredictability, which varies with the whims of weather (Monsoon Season) Cost of Solar Equipment for the poor – Financing schemes  Indian Renewable Energy Development Agency (IREDA) - a Public Limited Company, providing revolving fund to financing and leasing companies offering affordable credit for the purchase of PV systems
  • 21. But is it working? Thermal Program:  600,000 solar cookers have been produced.  2000 concentrating dish cookers  12 community village cookers and 1.5 million sq m of collector area for water heating systems have been achieved. Photovoltaic Program:  55000 street lighting systems  340,000 home lighting systems  1566 kW of power plants  540,000 solar lanterns have been produced
  • 22. Conclusion 700 Million Rural People x 80% of total energy for these needs ___________________________________ Making India’s rural population and India more energy independent
