Renewable energy

  1. 1. RENEWABLE ENERGY -B. Prasad Chartered Engineer amieclub@gmail.com
  2. 2. INTRODUCTION  Renewable energy is energy obtained from sources that are essentially inexhaustible.  Examples: wind power, solar power, geothermal energy, tidal power and hydroelectric power.  The most important feature of renewable energy is that it can be harnessed without the release of harmful
  3. 3. Sources of energy NON RENEWABLE  COAL  LPG  NATURAL GAS  NUCLEAR  FUEL CELL RENEWABLE  WIND  HYDRO  SOLAR  BIOMASS  BIOGAS  PHOTOVOLTAIC
  4. 4. ENERGY CONSUMPTION PER CAPITA COUNTRYCOUNTRY UNIT(KWH)UNIT(KWH) PAKISTANPAKISTAN 6969 INDONESIAINDONESIA 145145 INDIAINDIA 425425 CHINACHINA 12481248 UKUK 56005600 USAUSA 13000130000 5000 10000 15000 20000 25000 INDIA UK USA TOWNSHIP UNIT(KWH) UNIT(KWH)

  7. 7. Solar collector
  8. 8. Solarpond  6000m2 Solar pond at Bhuj dairy, Bhuj, Gujarat Designed and installed by TERI
  9. 9. Fresnel  ARUN160: Fresnel Paraboloid concentrator with cavity receiver with 2-axes tracking having 160 m2 aperture area installed under IIT- Bombay - Clique R & D Project sponsored by MNRE for milk pasteurization at Mahanand Dairy, Latur,
  10. 10. Solar street light  EXAMPLE  Height of pole: 4m  No. of lamp: 1  Type of lamp: CFL (11W)  No. Of battery : (12V,90Ah)  Cost :30000/-
  11. 11. SOLAR LIGHT
  12. 12. Solar power generation:PV CELL
  13. 13. MERITS/LIMITATION OF PV CELL  NOISE LESS  ABSENCE OF MOVING PART  ADDITIVE PROPERTY  EASY TO OPERATE  POLLUTION  DEPENDS ON SUN LIGHT  INITIAL COST IS HIGH  ENERGY STORAGE DEVICE IS REQUIRED Merit Limitation
  14. 14. Solar power on grid/of grid  off Grid solar power plant can obtain the solar energy from solar panel, and can stored in to the battery Banks  On Grid tie solar power plant can obtain the solar energy from solar panel, and can tie to the grid through its output cable with no battery backups. Off Grid SolarPowerPlant On Grid SolarPowerPlant
  15. 15. Solar power generation fact  Rate: 200/watt for smaller plant  Space required : 10 watt per squire feet  Solar Power Plant comes to Rs. 15 crore for each MW  cost of generation of solar power Rs.16/-approx.  Indian government is planning to offer a subsidy of 55% on installation of solar power in residential and commercial settings.
  16. 16. Solar Appliances in India  340,000 home illumination systems,  55,000 solar road lights,  1,500 of solar PV energy producing plants,  575,000 solar cookers,  560,000 solar lamps,  6,800 solar PV pumps and solar water heaters
  17. 17. PV water pumping system
  18. 18. Solar water heater: flat plate collector  Example:  Face area: 2 sq. Meter  Temperature range :50-70 deg.C  Cost:@Rs.180/LPD (Litre per day)  Module : 125LPD, 250LPD,300LPD
  19. 19. Solar water heater: evacuated tube collector  Example:  Face area: 2 sq. Meter  Temperature range :60-80 deg.C  Cost:@Rs.200/L PD(Litre per day)  Module : 125LPD, 250LPD,300LPD
  20. 20. Hydro energy  P= 9.8 Q Hη where:  P= power(KW) = plant efficiencyη Q = discharge flow rate (meter3 /s) H= head (meter)
  21. 21. Water flow
  22. 22. MERIT AND DEMERIT  Power at constant rate  Non -polluting  Lower operational cost  easy transmission  Help in irrigation projects.  Cater peak load  High investment costs  Loss of fish species  Cost for construction  Due to drought may become useless  Dams can break in a massive flash flood  Damming rivers causes changes in ecological cycles MERIT DEMERIT
  23. 23. ETHANOL,ETHYL ALCOHAL CH3CH2OH
  24. 24. USE OF ETHANOL  AS SOLVENT  GERMICIDE  ALCOHLIC BEVRAGE  ADHESIVE  FUEL FOR AUTOMOBILE
  25. 25. BIO DIESEL
  26. 26. BIOMASS
  27. 27. HYDROGEN ENERGY
  28. 28. Biogas
  29. 29. Bio gas fact and cost  1m3 bio gas =0.42litre of diesel  1m3 bio gas =0.468 kg LPG  1m3 bio gas =0.62L of kerosene  1m3 bio gas =3.5 kg fore wood  1m3 bio gas =1.25 KW Electricity  10 kg of waste per day = produces around 1 CUM of biogas.  Cost of the system is around Rs. 15000/- per CUM of plant.
  30. 30. ACT FAST AND INITIATE FIRST  बड़ा    सोचो         तेजी से सोचो व     सबसे पहले सोचो  िवचारो     पर िकसी का       एकािधकार नही होता.   ----  धीरभाई अमबानी
