Energy productions

  1. 1. By.., Darshan
  2. 2.  ... Energy production..  Renewable energy resources..  Non renewable energy resources..  Energy policy..  Energy reserves..  Energy consumption..  Energy and environmental concerns..
  3. 3.  Energy development is a field of endeavor focused on making available sufficient primary energy sources and secondary energy forms to meet the needs of society. ...
  4. 4.  These includes SOLAR, WIND, BIOMASS, AND SMALL HYDRO SOURCES!!!  Among the renewable sources,hydropower is the largest.  Wind power has also a great potential. wind mills and sails have been in use since ancient’s a fast growing resource.  The use of solar energy is through photovoltaic cells.  The biomass resource are various types of cultivated or unciltivated vegetation.
  5. 5. The energy policy of the govt. Aims to ensure adequate energy supplies at minimum possible costs,achieving self- sufficiency in energy supplies and protecting the environment from adverse impact due to utilisation of energy resources...
  6. 6. In Indian country COAL, OILAND NATURAL GAS resources are the primary commercial sources of energy...!!!!!  COAL: Indian ranks 3rd amongst the coal producing countries of the world.The bulk of the coal produced is inferior grade non-coking coal used to meet the demands of the power sector....
  7. 7.  Indian is the one of the least explored regions which a oil well density of 20per 10,000sq km as against world average of 100.  Of the 26 sedimenatary basins,only 6 have been explored so far, accounting for 30% the countries prognosticated reserves...s  Major product inported in 1998/99 were high speed disel oil, kerosine and liquified petroleum gas..
  8. 8. Major Energy consumption includes in these sectors...  INDUSTIAL SECTOR  TRANSPORT SECTOR  AGRICULTURAL SECTOR  DOMESTIC SECTOR
  9. 9.  This sector is the largest consumer of energy consuming about 50% of the total commercial energy produced in the country followed by the transport sector....!  COAL and LIGNITE contribute about 57%, OIL and GAS around 33%, HYDROELECTRIC POWER 3%, and NUCLEAR POWER 0.2% these are the commecial sources of energy used in Industrial sector.  Industrial sector consumed 104 biilion kWh from the utilities and 34 billion from in capative plants...
  10. 10.  In this sector largely consumes PETROLEUM products__ mainly in the form of High speed diesel(HSD)and Gasoline and accounts for nearly 50% of total consumption..  Consumption of HSD increased from about 9million tonnes in 1980/81 to 30MT in 1996/97.  The higher rates of growth in energy consumption in1990s primarily due to increase in the share of road transport visa-a-vis rail for both passenger & freight movements & a phenomenal increase in the no. Of personalised vis-a-vis public vehicles.  This has serious implications for health and environment
  11. 11.  This sector consumption of commercial energy has grown significantly with increased of mechanisation & modernisation of agricultural activities..  The relative share of electricity & diesel power as against human & animal labor has increased significantly from 5.37% in 1950/51 to almost 50% of the total farm power consumed for irrigation in 1995/96  Elecricity consumption by agriculture has grown from 8.7billion kWh in 1975/76 to 23.4billion kWh in 1985/86 and to 34billion kWh in 1996/97.
  12. 12.  The consumption of biomass(wood) energy is very high.  Around 78% of rural & 30% of urban households depends on firewood.  However, the fix of traditional fuelsin the national energy mix is decreasing as efficient commericial fuels are increasingly substituting these.  In b/w 1970/71 & 1994/95, the annual consumption of electricity per household went up from 7kWh to 53kWh: of kerosine from 6.6kg to 9.9kg & of cooking gas from 0.33kg to 3.8 kg.
  13. 13.  The environmental effects of the use of various fuels are of serious concern owing to increasing consumption levels.  Pollutants associated with the combustion of fossil fuels, viz.., SPM, SO2,Nox, & CO pose a major threat to environmental qulity and human health.
  14. 14.  The problem is compounded due to poor qulality 7 of Indian coal  In addition to the emissions, land requirements for the disposal of fly ash generated in the thermal power plants is a major concern.  Electric power generation is also the largest source of GREENHOUSE gasses & accounts for 48% if carbon emitted.  The nuclear option comes with its own set of problems.  Large hydro projects in turn, may entail serve often irreriable social & environmental costs including the dislocation of people...
  15. 15.  The contribution of natural gasses to energy management is a significant step.  Advanced technologies for electric power generation have resulted in energy efficiency gains.  Fuel cells that combine hydrogen and oxygen electrochemically to produce electricity, water and heat.  Biomass as another source energy. It has environmental implications and its is use is being examined after taking into consideration the biodiversity and pollution effects aspects.  Photovolatic cells trap solar energy to produce
