Question
Read the case given below and answer the questions that follow:
Energy can be generated from fuel minerals like coal, petroleum, natural gas, uranium and from electricity. Energy resources can be classified as conventional and non-conventional sources. Conventional sources include: firewood, cattle dung cake, coal, petroleum, natural gas and electricity (both hydel and thermal). Non-conventional sources include solar, wind, tidal, geothermal, biogas and atomic energy. Firewood and cattle dung cake are most common in rural India. According to one estimate, more than 70 percent energy requirement in rural households is met by these two, continuation of these is increasingly becoming difficult due to decreasing forest area. Moreover, using dung cake too is being discouraged because it consumes most
valuable manure which could be used in agriculture.
Q.1. Which conventional energy source are mostly used in rural areas?
Q.2. It is becoming difficult to continue the use of firewood and cattle dung. What is the reason?
Q.3. What are conventional sources of energy? Give two examples.
