Save mother earth

  1. 1. English Project Work
  2. 2. Acting To Save Mother Earth
  3. 3. <ul><li>Made By : - </li></ul><ul><li>Nihal Gour , Ayush Jain , Savinay P. Singh and Ketan Sharma </li></ul><ul><li>Submitted to :- </li></ul><ul><li>Mr. D. K . Tiwari </li></ul>
  4. 4. <ul><li>Everyday we hear more bad news about our planet. </li></ul><ul><li>Reports tell us that wildlife and forests are disappearing at an alarming rate. </li></ul><ul><li>Newscasts give the latest word on how quickly earth is losing its protective shield (Ozone) and warming up. </li></ul><ul><li>Newspapers lament the pollution of our air, water, and soil. </li></ul><ul><li>What can we do in the face of such widespread gloom? </li></ul><ul><li>In fact, we do not have to feel helpless. We can each learn practical ways to better our environment. </li></ul>
  5. 5. <ul><li>In this project, Focus is on two major topics of Today's World, namely : </li></ul><ul><li>solar energy and </li></ul><ul><li>Energy Conservation </li></ul>
  6. 6. <ul><li>We hear everyday, on TV, newspapers, magazines, that we have to save the planet. </li></ul><ul><li>Did you know there's areas in this world who don't have Power, they don't even know it exist, but on the other part of the world we as humans are wasting it. </li></ul><ul><li>There is an alternative to this problem, and a good one. </li></ul><ul><li>We have it on the top of our head everyday.  </li></ul>It Is called…………….
  7. 7. Solar Energy (A very brief introduction and its advantages) 1
  8. 8. <ul><li>Solar Energy, the energy generated by the sun. This energy is in the form of electromagnetic radiation and travels to the earth in waves of various lengths. </li></ul><ul><li>Some of the radiation becomes evident as heat, some as visible light. </li></ul><ul><li>All life on earth depends ultimately on the sun's radiation. </li></ul><ul><li>It warms the earth and provides the energy that green plants use to make their food. (Without plants, there would be no animals, since all animals must feed on plants or on plant-eating organisms.) </li></ul>
  9. 9. <ul><li>Since ancient times attempts have been made—with varying success—to put the energy from the sun to practical use. </li></ul><ul><li>In the third century B.C., the Greek mathematician and physicist Archimedes is said to have used the sun's rays reflected from mirrors to set fire to an invading Roman fleet. </li></ul><ul><li>In the 19th century, John Ericsson, designer of the ironclad warship Monitor, built an engine that was powered by the sun's energy. </li></ul>
  10. 10. <ul><li>You've probably seen calculators with solar cells -- devices that never need  batteries  and in some cases, don't even have an off button. </li></ul><ul><li>As long as there's enough  light , they seem to work forever. </li></ul><ul><li>Although larger panels aren't as common as solar-powered calculators, they're out there and not that hard to spot if you know where to look. </li></ul><ul><li>In fact,  photovoltaics  -- which were once used almost exclusively in space, powering satellites' electrical systems as far back as 1958 -- are being used more and more in less exotic ways. </li></ul>
  11. 11. <ul><li>The technology continues to pop up in new devices all the time, from sunglasses to electric vehicle charging stations. </li></ul><ul><li>The hope for a &quot;solar revolution&quot; has been floating around for decades -- the idea that one day we'll all use free electricity fro m the  sun . </li></ul><ul><li>This is a seductive promise, because on a bright, sunny day, the sun's rays give off approximately 1,000 watts of energy per square meter of the planet's surface. </li></ul><ul><li>If we could collect all of that energy, we could easily power our homes and offices for free. </li></ul>
  12. 12. Did you know? <ul><li>More than 10,000 homes in the United States are powered entirely by solar energy. </li></ul><ul><li>Enough sunlight falls on the earth's surface every hour to meet world energy demand for an entire year. </li></ul><ul><li>Silicon from just one ton of sand, used in photovoltaic cells, could produce as much electricity as burning 500,000 tons of coal. </li></ul>
  13. 13. Advantages of Solar Energy
  14. 14. <ul><li>Solar energy is everywhere, it’s abundant and we’ll practically never run out. </li></ul><ul><li>Even in mid winter we are blessed with a moderate amount of natural daylight provided courtesy of the sun. </li></ul><ul><li>Okay, it might not be sunny everyday but we are still experiencing radiation from the sun and it is this which can be gleaned for our own renewable energy purposes. </li></ul><ul><li>Thus the need for finding a long lasting energy resource is over! </li></ul>Solar Energy Is Abundant
  15. 15. <ul><li>Solar energy is completely free. </li></ul><ul><li>Sure, there is an initial capital cost but once you have made the investment the energy harvested from the sun costs you nothing. </li></ul><ul><li>No one will be sending you a bill for sunshine. </li></ul><ul><li>Thus no worries of spending enormous amounts of your salary in satisfying your energy requirements. </li></ul>Solar Energy Is Free
  16. 16. <ul><li>While solar photovoltaic are still relatively expensive, the technology is growing rapidly as is production – and as a result the costs involved are coming down and is now cost effective. </li></ul><ul><li>Solar hot water panels have been greatly improved in recent years and, with lower cost, payback times for domestic systems can no be as short as five years. </li></ul><ul><li>As coal, gas and oil prices continue to rise solar energy will become a viable alternative. </li></ul><ul><li>It’s secure. We live in uncertain times and we are increasingly relying on our fossil fuel supplies coming from areas abroad over which we have little or no control. </li></ul>Solar Energy Is Cost Effective
  17. 17. <ul><li>Finally solar energy is clean. </li></ul><ul><li>It is a clean alternative to fossil fuels and nuclear power and it will never run out. It’s silent. </li></ul><ul><li>Solar power can be captured anywhere without creating noise pollution that might otherwise up set neighbors and wildlife. </li></ul><ul><li>It works wherever the sun shines. It doesn’t matter how remote, solar can generate energy where no other form of power can be obtained. </li></ul><ul><li>Thus, no danger of damaging our already damaged environment further and you can be part of the  Green  initiative, lower your carbon footprint, and save our planet from harmful greenhouse gases. </li></ul>Solar Energy Is Clean
  18. 18. So, for a brighter future……… LET THE SUNSHINE IN !!
  19. 19. Energy conservation 2
  20. 20. <ul><li>We all know that it’s important to save energy. </li></ul><ul><li>In fact it’s been impossible to ignore the headlines telling us to do our bit for the environment, reduce our carbon footprint, adopt a greener lifestyle, and so on. </li></ul><ul><li>But how many of us know the hard facts as to why we need to change our ways, and why saving energy is so important? </li></ul><ul><li>We need to motivate ourselves into becoming more efficient with the way we use energy in the home, at work and in our everyday lives. </li></ul>
  21. 21. It’s simple Definition <ul><li>Energy conservation  refers to efforts made to reduce energy consumption. </li></ul><ul><li>Energy conservation can be achieved through increased efficient energy use, in conjunction with decreased energy consumption and/or reduced consumption from conventional energy sources. </li></ul><ul><li>Energy conservation can result in increased financial capital, environmental quality, national security, personal security, and human comfort. </li></ul><ul><li>Individuals and organizations that are direct consumers of energy choose to conserve energy to reduce energy costs and promote economic security. </li></ul><ul><li>Industrial and commercial users can increase energy use efficiency to maximize profit. </li></ul>
  22. 22. Energy Conservation in India
  23. 23. <ul><li>Petroleum Conservation Research Association (PCRA) is an Indian government body created in 1976 and engaged in promoting energy efficiency and conservation in every walk of life. </li></ul><ul><li>In the recent past PCRA has done mass media campaigns in television, radio & print media. </li></ul><ul><li>An impact assessment survey by a third party revealed that due to these mega campaigns by PCRA, overall awareness level have gone up leading to saving of fossil fuels worth crores of rupees besides reducing pollution. </li></ul><ul><li>Bureau of Energy Efficiency is an Indian governmental organization created in 2002 responsible for promoting energy efficiency and conservation. </li></ul>
  24. 24. Major Advantages of Energy conservation
  25. 25. <ul><li>Less need to secure oil and natural gas overseas with attendant military and civilian casualties while costing hundreds of billions of dollars </li></ul><ul><li>Fewer power plants and liquid natural gas ports are needed </li></ul><ul><li>Less air pollution </li></ul><ul><li>Less drilling for oil in Alaska and near national parks </li></ul><ul><li>Less global warming and attendant environmental destruction </li></ul><ul><li>Energy conservation has saved the need for many power plants and fuel imports. </li></ul><ul><li>It has also avoided CO2 and environmental pollution. </li></ul><ul><li>Solar energy is a reliable and never ending source of energy. Although the initial cost of using the solar energy may be high, the high price can be recovered as after the system is installed, there will be no cost of producing the electricity. </li></ul><ul><li>We start living in an atmosphere, where we would not be selfish, looking at our needs but also pondering over the needs of our future generations.  </li></ul>
  26. 26. Energy Conservation Tips
  27. 27. Conservation in Lighting
  28. 28. <ul><li>Don't leave lights on when no one is in the room. If you are going to be out of the room for more than five minutes, turn off the light. Where possible, use compact fluorescent light bulbs. Those funny-looking bulbs produce the same amount of light by using 1/4 of the electricity. Plus, they last for years and years without burning out. Replace flickering, dim and burned-out lamps Keep light fixtures clean – a cleaner bulb is a brighter bulb Lower overall energy demand by concentrating bright light where you need it rather than evenly lighting the entire room – this is called ‘task lighting’ Lower the height of light fixtures if possible to increase usable light. Replace burned out lamps with lower wattage lamps or energy-saving lamps wherever possible. Install more efficient security and parking lot lighting. High-pressure sodium fixtures are more efficient than metal halide, mercury vapor, fluorescent or incandescent fixtures. </li></ul>
  29. 29. Cont . <ul><li>Install time clocks or photoelectric cells to control exterior lighting, advertising sign lighting and some interior lighting. Paint dark walls and ceilings with lighter colors to maximize the effect of existing light sources. Maximize natural lighting by installing skylights or windows. Install dimmer or occupancy switches where appropriate to lower energy use such as in stairwells, copy rooms, restrooms. Implement a group re-lamping schedule, and re-lamp at 70% of rated lamp life. Lamps that run longer than 70% of their rated life actually cost more in terms of energy use. Trim bushes and trees away from outdoor lighting to maximize illumination and prevent shadows. </li></ul>
  30. 30. Energy Conservation at Home
  31. 31. <ul><li>Keep refrigerators and freezers out of direct sunlight, and allow at least 5 centimeters all around to allow heat to escape from the compressor and condensing coil. </li></ul><ul><li>Clean your refrigerator’s coils (back) and air intake grill (below the doors) every 3 months. </li></ul><ul><li>Don’t let freezers build up more than 6 mm of frost. Defrost regularly to keep freezers working their best. </li></ul><ul><li>Plant trees or shrubs to shade air-conditioning units but not to block the airflow. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun. </li></ul><ul><li>Turn off the TV when no one is watching it. The same goes for computers, radios and stereos . </li></ul><ul><li>Don't keep the refrigerator door open any longer than you need to. Close it to keep the cold air inside! Also, make sure the door closes securely. </li></ul>
