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