2. Give two points of diferences between the conventonal and the non-conventonal source, of energy, conventional, It is non renewable, Coal, petroleum, natural gas is necessary for, generatng energy, Creates polluton and not sustainable, , Non conventional, renewable, sunlight, wind, biogas are needed to produce, energy, Eco-friendly and sustainable, , 3. Classifed coal reserve of India on the basis of their Geological age., Ans: Coal reserve of India is classifed into two, Gondwanda and Tertary. Gondwanda coal, reserve are said to be 200 million years old while the Tertary reserve are about 55 million years., 4. Why are petroleum refneries known as nodal industry?, Ans: Petroleum and its by product is used in many other industries like fertliier, synthetc textle, and chemical industries so it it is called nodal industries., 5. Explain how tdal energy is generated?, Ans: Floodgate dams are built to trapped water during high tdes and when the water recedes,, the water is release through the turbine to generate electricity., 6. Where are the two geothermal energy plants located in India?, Ans: One at Parvat alley in imachal Pradesh and the other at Puga alley in Ladakh., 7. Explain the importance of bio gas as a source of non-conventonal energy?, Ans: Biogas are derived from biological products such as bagasse, farm waste, rice husksewage,, vegetable waste, animal and poultry waste and human excreta. The power so produce is used in, cooking, lightng homes and streets in villages. So the energy is clean and renewable., 8. Why is it necessary for us to conserve energy resources?, Ans: At the current rate of energy consumpton it will only last 30-40 years. So wise use of, energy is needed, changing from conventonal sources like coal, petroleum etc. to nonconventonal sources like sunlight, wind and hydel., 9. Suggest two measures to be taken up for efcient use of energy?, Ans: Conduct awareness programme and encouraging public mode of transport then private, 10. Give two reasons why non-conventonal source of energy has a bright future?, Ans: 1. It is renewable and 2. Eco-friendly and sustainable
