NEED OF RENEWABLE ENERGY DEFINITION OF RENEWABLE ENERGY VARIOUS FORMS OF RENEWABLE ENERGY AND ITS ADVANTAGES RENEWABLE ENERGY IN INDIA 30-12-2013 2 3. 30-12-2013 3 4. energy resource naturally regenerated over a short time scale directly from the sun (thermal) indirectly from the sun (wind, hydropower) from other natural movements and mechanisms of the environment (geothermal, tidal energy). 30-12-2013 4 5. 1.When its source cannot run out (like the sun) or can easily be replaced (like wood). 30-12-2013 5 6. 2. When their sources are carbon neutral. That means they do not produce carbon compounds (such as other green house gases). 30-12-2013 6 7. 3.When they do not pollute the environment. (air, land or water). 30-12-2013 7 8. 1) WIND ENERGY 2) SOLAR ENERGY 3) BIOFUELS 4) HYDROPOWER a) Small hydro b) OCEAN Thermal c) TIDAL d) WAVE action energy 5) GEOTHERMAL ENERGY 30-12-2013 8 9. The largest wind turbine in the world, located in Hawaii, stands 20 stories tall and has blades the length of a football field. An average wind speed of 14 miles per hour is needed to convert wind energy into electricity. The first power-generating turbine was constructed in Ohio during the late 1800's and was used to charge batteries. Wind energy is the fastest growing segment of all renewable energy sources. 30-12-2013 9 10. WIND TURBINES REQUIRE NO FUEL WIND TURBINES DO NOT PRODUCE ANY WASTES, GREENHOUSE GASES, TOXINS OR BY-PRODUCT THAT CAN HARM THE ENVIRONMENT. 30-12-2013 10 11. CREATES MORE JOBS 30-12-2013 11 12. LAND BENEATH WIND TURBINE CAN BE USED FOR FARMING AND GRAZING 30-12-2013 12 13. A good method of supplying energy to remote areas 30-12-2013 13 14. Wind farms can be built offshore 30-12-2013 14 15. It is considered 'renewable energy' because... The technology used to convert the sun's power into electricity does not produce smoke (carbon dioxide and other air pollutants). Tapping the sun's energy does not usually destroy the environment. 30-12-2013 15 16. 30-12-2013 16 Largest solar thermal power plant generating facility in the world: Solar Energy Generating Systems (SEGS) in California, with the combined capacity from three separate locations at 354 megawatts. 17. Solar energy will last forever whereas it is estimated that the worlds oil reserves will last for 30 to 40 years. 30-12-2013 17 18. Solar cells make absolutely no noise at all. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical. 30-12-2013 18 19. Very little maintenance is needed to keep solar cells running. There are no moving parts in a solar cell which makes it impossible to really damage them. 30-12-2013 19 20. Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. 30-12-2013 20 21. Solar energy does not cause pollution. However, solar collectors and other associated equipment / machines are manufactured in factories that in turn cause some pollution 30-12-2013 21 22. Biomass is used to make biofuels. Biomass is biological material derived from living, or recently living organisms. Biofuels are liquid fuels which have been derived from other materials such as waste plant and animal matter. 30-12-2013 22 23. Waste residues will always exist in terms of scrap wood, mill residuals and forest resources. Properly managed forests will always have more trees, and we will always have crops and the residual biological matter from those crops. 30-12-2013 23 24. 30-12-2013 24 25. It makes use of waste materials. 30-12-2013 25 26. Biofuel is cheap. It will lead to less demand on fossil fuels. 30-12-2013 26 27. Hydropower is renewable energy source that doesn't cause global warming because it doesn't releases dangerous greenhouse gases. China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States (Source: Energy Information Administration). Hydropower is the most important and widely-used renewable source of energy. 30-12-2013 27 28. 30-12-2013 28 29. 30-12-2013 29 30. To meet any changes in demand for electricity, hydroelectricity generators can be stopped and started in minutes. A fossil fuel power station can take up to eight hours to shut down or restart A nuclear power station can take up to several days. 30-12-2013 30 31. Operation and maintenance costs for hydroelectricity plants are much lower than for thermal electricity power plants. Breakdowns are few because their mechanical design is relatively simple, and no excess heat is generated during operations. 30-12-2013 31 32. Constant rate of electricity production Long life No waste by- products 30-12-2013 32 33. Geothermal energy is the heat from the Earth. Geothermal energy is called a renewable energy source because the water is replenished by rainfall, and the heat is continuously produced by the earth. 30-12-2013 33 34. The Pohutu Geyser in New Zealand erupts with a natural blast of the Earth's interior heat. 30-12-2013 34 35. Because geothermal energy is energy in and of itself, no outside sources of fuel are needed to keep the power houses running. The supply of this renewable energy is constant, as well as without limits since the earth is never going to stop producing heat energy and in theory, energy is abundant enough to supply all the needs of all mankind. 30-12-2013 35 36. First country in the world to set up a ministry of non conventional resources, in early 1980s The renewable power installed capacity forms 12% of the total installed capacity as on Oct 2012 Actual electricity generation from renewable energy sources equals 49.04 billion units. 30-12-2013 36 37. RE generation from Small Hydro power is 3421 MW, i.e 13% of RE With 17,875 MW of generation, wind continues to account for 70% of the installed RE capacity 30-12-2013 37 38. 30-12-2013 38 Renewable Energy Capacity of India as of 2012 39. 30-12-2013 39 Wave energy Plant at Vizhinjam near Trivandrum in India 40. Radiant energy Compressed natural gas Anaerobic digestion Hydrogen Antimatter Nuclear 30-12-2013 40 41. Renewable Energy Sources and Emerging Technologies By D.P Kothari, K.C Singal, Rakesh Ranjan.
