  12. 12. Introduction NAVEED UR REHMAN www.naveedurrehman.com www.naveedurrehman.com 12
  13. 13. INTRODUCTION All the renewable energy sources are principally derived from the enormous power of Sun's radiation. www.naveedurrehman.com 13
  14. 14. INTRODUCTION These renewable energy sources are at once, the most ancient and now, the most modern forms of energy used by humanity. www.naveedurrehman.com 14
  15. 15. INTRODUCTION Solar power is one of the ultimate sources of energy upon which early human societies were based. www.naveedurrehman.com 15
  16. 16. INTRODUCTION When our ancestors first used fire, they were harnessing the power of photosynthesis which is a solar driven process by which plants are created from water and atmospheric carbon dioxide. www.naveedurrehman.com 16
  17. 17. INTRODUCTION Societies went on to develop ways of harnessing the movements of water and wind to grind corn, irrigate crops and propel ships. www.naveedurrehman.com 17
  18. 18. INTRODUCTION Both the natural movements of water and wind are caused by solar heating of the oceans and atmosphere. www.naveedurrehman.com 18
  19. 19. INTRODUCTION As civilizations became more sophisticated, architects began to design buildings to take advantage of the Sun’s energy by enhancing their natural use of its heat and light, so reducing the need for artificial sources of warmth and illumination. www.naveedurrehman.com 19
  20. 20. INTRODUCTION Technologies for harnessing the power of Sun, water and wind continued to improve right up to the early years of the industrial revolution. www.naveedurrehman.com 20
  21. 21. INTRODUCTION However, by then the advantages of coal, the first of the fossil fuels to be exploited on a large scale, had become apparent. www.naveedurrehman.com 21
  22. 22. INTRODUCTION These highly-concentrated energy sources soon displaced wood, wind and water in the homes, industries and transport systems of the industrial nations. www.naveedurrehman.com 22
  23. 23. INTRODUCTION Today the fossil fuel trio of coal, natural gas and oil provide over 80% of the world’s energy. www.naveedurrehman.com 23
  24. 24. INTRODUCTION Concerns about the adverse environmental and social consequences of fossil fuel use, such as air pollution, oil spills, mining accidents, deforestation and about the finite nature of supplies, have been voiced intermittently for several centuries. www.naveedurrehman.com 24
  25. 25. INTRODUCTION But it was not until the 1970s, with the steep price rises of the ‘oil crisis’ and the advent of the environmental movement, that humanity began to take more seriously the prospect of fossil fuels ‘running out’, and the possibility that their continued use could be destabilizing the planet’s natural ecosystems and the global climate. www.naveedurrehman.com 25
  26. 26. INTRODUCTION The development of nuclear energy following World War II raised hopes of a cheap, plentiful and clean alternative to fossil fuels. www.naveedurrehman.com 26
  27. 27. INTRODUCTION However, nuclear power development has stalled in some countries in recent years, due to increasing concern about safety, cost, waste disposal and weapons proliferation, although in other countries nuclear expansion is continuing. www.naveedurrehman.com 27
  28. 28. INTRODUCTION Continuing concerns about the ‘sustainability’ of both fossil and nuclear fuel use have been a major catalyst of renewed interest in the renewable energy sources in recent decades. www.naveedurrehman.com 28
  29. 29. INTRODUCTION Now, what is a Sustainable Energy Source? Sustainable energy source is one which help this world in meeting its present needs without depleting of serving next generation’s needs. www.naveedurrehman.com 29
  30. 30. INTRODUCTION Sustainable energy does not involve significant pollutant emissions or other environmental problems. www.naveedurrehman.com 30
  31. 31. INTRODUCTION Also, sustainable energy does not involve the spread of substantial health hazards or social injustices. www.naveedurrehman.com 31
  32. 32. INTRODUCTION At present, oil and gas present at large scale and thus are sustainable energy sources. www.naveedurrehman.com 32
  33. 33. INTRODUCTION What is a Renewable Energy Source? Renewable energy source include such a natural source which can be replaced by natural ecological cycles. That is, they renew thus never gets deplete. www.naveedurrehman.com 33
  34. 34. INTRODUCTION Tidal, wave, geothermal, wind and solar energies are counted as renewable energy sources. www.naveedurrehman.com 34
  35. 35. INTRODUCTION The energy coming from sun and wind can be characterized as both sustainable and renewable energy sources. www.naveedurrehman.com 35
