And we similarly hope that all the non-conventional sources will become conventional, common, and every day, as they are all free, green and emit no carbon dioxide (well, biomass does, but it prevents the production of methane which is a greenhouse gas 21 times more dangerous that CO2). Example: petroleum, coal, water power and natural gases. Their use causes pollution as they emit ash and smoke. Humans get energy from food which has this energy stored in form of chemical energy. Types of conventional sources of energy include coal, petroleum, natural gas. Coal is a complex mixture of compounds of carbon, hydrogen and oxygen. Land-locked states can't have ocean energy sources available. When we cannot reuse a source of energy after using it once we call them “conventional sources of energy” or “non-renewable energy resources”. This edition is also pedagogically enhanced due to the addition of solved university questions, objective Questions Your body absorbs this energy from food and burns it to fuel your body so that you can run around and have fun. conventional sources of energy are those sources energy which are non-renewable.for example such as:coal, oil shale and tar sands. Small amounts of nitrogen and Sulphur compounds are also present in coal. Non-conventional energy sources that are location-specific have limited accessibility. These sources of energy are being used extensively in such a way that their known reserves have been depleted to a great extent. The non-conventional sources of energy are abundant in nature. Conventional and Non-Conventional Sources of Energy. 3. It is mainly available in Bihar, West Bengal, Orissa and Madhya They are in use for a long time. Some non-conventional sources are - Solar Energy, Wind Energy, Tidal Energy, Geothermal Energy, Biomass. Conventional : Energy that has been used from ancient times is known as conventional energy. Non Conventional Energy In India, non-conventional energy sources consist of those energy sources that are infinite, natural, and restorable. States that do not have deserts, estuaries, geothermal locales, or large tracts of available land free of development won’t be able to take advantage of solar, hydropower, geothermal or wind energy resources. Therefore you must unlock this energy to get work done. Importance of non-conventional sources of energy: 1. (or usual) sources of energy (electricity) are coal, oil, wood, peat, uranium.  Generally, these resources are locked in geological structures where extraction is not economically or technologically feasible, however with technological advancements these can turn into viable fossil fuel reserves .
