Renewable and Non-Renewable Energy Sources.Those sources of energy which have accumulated in nature over a very, very long time and cannot be quickly replaced when exhausted are called non-renewable sources of energy. For example, coal is a non renewable source of energy because coal has accumulated in the earth over a very, very long time, and if all the coal gets exhausted, it cannot be produced quickly in nature (see above figure). The non-renewable sources of energy are N Fossil fuels (Coal, Petroleum and Natural gas), and Nuclear fuels (such as Uranium). Non-renewable sources of energy are dug out from the earth.1. The sources of energy which can not be quickly replaced when exhausted are calleda. Renewableb. Non-renewable2. Which of the following is not a non-renewable source of energy?a. Solar energyb. Coalc. Petroleumd. Natural gas3. Which of the following is a non-renewable source of energy?a. Windb. Uraniumc. Solar energyd. Tidal energy4. The sources of energy which can be dug out from the earth area. Non-renewableb. Renewablec. Both of thesed. None of these5. Non-renewable source of energy are :a. Quickly replacableb. Slowly replacablec. Irreplaceabled. None of these
