  • 1. Wastage of Natural Resources ELECTRICITY Presentation By Muhammad Waqas Jawed Roll No. 08-0441, 1 st Semester, Section A BS (CS)
  • 2. Introduction
    • Electricity plays an important part in our lives.
    • Without electricity, one can only imagine how difficult and tedious life would be.
      • Without electricity
        • nights would be spent in darkness
        • the internet is unthinkable and it would be as if everybody were back, living in the Stone Age.
      • But as human ares, when we have, we waste.
      • Are we going to wait till the end of the world before we learn about our mistakes?
      • By then, all will be useless, so treasure what you have now and CONSERVE!
    • This presentation will briefly cover the wastage and conservation of electrical energy
  • 3. Contributors to Electricity Production
    • Fossil Fuels 60%
      • Coal 25%
      • Oil 15%
      • Gas 20%
    • Hydro Electric Power 20%
    • Nuclear 11%
    • Other 8%
    • FOSSIL FUELS ARE MAJOR CONTRIBUTERS TO PRESENT DAY ENERGY PRODUCTION AND THESE ARE NOT GOING TO LAST MUCH
  • 4. Fossil Fuels: What We Have??
    • Proved Reserves
    • Oil: 1,119 to 1,317 billion barrels
    • Gas: 6,183 - 6,381 trillion cubic feet = 1,161 billion barrel oil equivalent
    • Coal: 997,748 million short tons = 4,416 billion barrel oil equivalent
    • Daily Production Rates
    • Oil: 84 million barrels per day
    • Gas: 19 million barrels oil equivalent per day
    • Coal: 29 million barrel oil equivalent per day
    • Years of production left in the ground with the most optimistic proved reserve estimates
    • Oil: 43 years
    • Gas: 167 years
    • Coal: 417 years
    • These are 2006 Estimates the consumption is exponentially increasing and the reserves will last for much less time then expected above.
  • 5. How Do We Waste Electricity?
    • City Lights
      • Major source of electricity wastage
    • Inefficient machines
      • Conversion of electrical energy to mechanical and other form of energy is not efficient and more than 20% of electricity is wasted in this operation
    • Careless Attitudes of Consumers
      • Consumers mistakenly think that they have right to waste energy when they are paying for it!
      • This attitude is not correct, we have no right to use the resources which are right of our future generations
  • 6. Environmental Consequences!!
    • Not only we are wasting the precious natural resources but we are causing disastrous effects on our climate
    • When more electricity is produced more CO2 is pumped into the atmosphere.
    • This is causing
      • Green House Effect
      • Making Climate Changes
      • Disturbing the ecology of the Planet Earth
  • 7. How Should We Save? Start From Our Homes!!!
    • Electric Bulbs
      • Major contributor in electricity wastage. Only 5% converted into light 95% wasted in heat
      • Use efficient bulbs called “Energy Savers”
    • Fan
      • Waste electricity in overcoming friction and in generation of heat at regulator
      • Use properly lubricated fans with at high speed.
    • Refrigerator
      • Ovoid frequent opening of door
    • Electric Iron
      • Cultivate culture to iron cloths on weekly basis, it will not only save energy but time also
    • TV / DVD
      • TV / DVD should be turned on only when being watched.
    • Air Conditioner
      • Major contributor of energy crisis in hot countries. Should be very carefully used
    • Washing Machines
      • Loading of dirty linen should be such that maximum machine capacity is utilized.
  • 8. Thank You
