Renewable sources of energy

  1. 1. RENEWABLE SOURCES OFENERGY BASKAR R
  2. 2. WHAT IS ENERGY Capacity to do work It can not be created One form of energy can be converted into other form of energy
  3. 3. WHAT IS RENEWABLE ENERGY ? Energy derived from natural Continuously produced in nature Non exhaustible Clean alternative to fossil fuels
  4. 4. WHAT IS AN ALTERNATIVE SOURCE OFENERGY? An energy source that can be used instead of fossil fuels It is usually a renewable source of energy that could be used should fossil fuels run out
  5. 5. SOURCES Solar energy Wind energy Bio mass energy Geo thermal energy Tidal energy Hydro energy
  6. 6. SOLAR ENERGY The energy utilized from sun light is called solar energyThere are two methods for harvesting solar energy Concentrating Solar thermal Plant(CSP) Photovoltaic plants(PV)
  7. 7. CSP
  8. 8. SOLAR PHOTOVOLTAIC PLANTS
  9. 9. WIND ENERGY Moving air = wind Energy that got from wind is called wind energy Wind turbines are used for getting energy Each wind turbine can produce between 0.25 to 2 MW of electrical power. Wind farm needs to be located where there is a relatively high average wind speed. It requires min 15km/hr speed of wind
  10. 10. WIND TURBINE
  11. 11. TIDAL ENERGY
  12. 12. HYDEL ENERGY Currently largest source of electricity from renewables. Needs guaranteed supply of water. Kinetic energy of water rotates turbines which generate electricity.
  13. 13. WORKING OF HYDEL PLANTS
  14. 14. GEO THERMAL ENERGY The heat that used for geo thermal energy can be derived from deep within earth Heat conducts from core to sorrounding rock High temp and pressure cause rock to melt which is called “Magma” Magma converts upwards
  15. 15. GEO THERMAL POWER PLANT
  16. 16. ENERGY FROM WASTES
  17. 17. GREEN POWER 100% pure RDF(Refuse Derived Fuel) 15MW power plant in Surat , Gujarat by Hanjer Biotech energies The RDF generated from municipal solid waste is dried , crushed and then packed to brick form 300 tones of RDF required
  18. 18. ADVANTAGES OF USING NATURAL SOURCESOF ENERGY They are inexhaustible – they will always be available – they are renewable They are clean and will not damage the Earth There are several types – so one or more of them is present in each country Most natural sources can be used on a small scale and serve local needs therefore cutting costs of transmitting the energy
