The document discusses and classifies various energy sources. It outlines primary energy resources which include fossil fuels, nuclear fuels, hydro energy, solar energy, wind energy, geothermal energy, and ocean energy. Secondary energy resources derive from primary sources and include petrol, diesel, kerosene oil, CNG, and LPG. Energy sources are also classified based on being conventional or non-conventional as well as renewable or non-renewable. Key energy sources discussed in more detail include petroleum, natural gas, solar energy, and hydroelectric energy.
Various types of energy sources
- 1. VARIOUS ENERGY SOURCES Presented by Abir Tasrif Anto ID: 111-23-2364
- 2. Energy & its classification Energeia is the Greek word for energy, meaning in or at work. Energy is the capacity for doing useful work. It is a primary input in any industrial operation. Energy is also a major input in sectors such as commerce, transport, telecommunication, different services required in the household and industrial sectors, etc.
- 3. Classification of Energy Resources on the basis of availability: Primary energy resources: 1. Fossil fuels such as coal natural gas etc. 2. Nuclear fuels such as Uranium, Thorium etc. 3. Hydro energy 4. Solar energy 5. Wind energy 6. Geothermal energy 7. Ocean energy such as tidal energy, wave energy 8. Hydrogen energy Secondary energy resources: 1. Petrol, diesel, kerosene oil. 2. CNG and LPG 3. Electrical energy based on coal, diesel gas.
- 4. On the basis of being older and newer Conventional Energy Resources 1. Fossil fuel 2. Nuclear energy 3. Hydro energy Non-conventional Energy Resources 1. Solar energy 2. Wind energy 3. Geothermal energy 4. Ocean energy 5. Biomass energy 6. H2 energy.
- 5. On the basis of renewable and non-renewable energy resources Non-renewable energy resources: From the last few decades oils and natural gases together with hydro-electricity and natural sources occupy the first position in producing energy to mankind. In the near future, power generation may become cheaper option, but it would be dangerous and harmful. Excessive use of fossil fuels leads to environmental pollution, out of which C02 emission is of immense concern. Thus it is important for us to exploit fuels in a balanced way to avoid any future shortage. Renewable energy resources: It holds favorable future prospects not only for India but also for the whole world. These ecofriendly energy resources have the greatest potential to substitute the depleting non-renewable energy resources as alternative sources of energy in the long run.
- 6. Petroleum or Crude Oil The gaseous fuels are basically derived from petroleum. It is a natural, underground fossil energy resource. It is formed due to decomposition of micro plankton deposited upon the sea beds, lakes and rivers for millions of years. The decomposition takes place by the action of bacteria, under lack of oxygen and also by catalytic cracking. It is also called crude oil. 1. Liquid fuel is easy to transport. 2. Liquid fuel is comparatively cleaner. 3. They have made possible the introduction and development of newer means of transport.
- 7. Natural Gas After coal and petroleum, natural gas is the third major source of fossil fuel. It contributes to about 24% of the energy requirement of the world. It is fast emerging as an alternative source as it is eco-friendly in characters. It is a mixture of hydrocarbon gases trapped beneath the earth’s surface. It is mainly consisting of methane (CHJ, propane (C3H8) and butane (C4H10). After processing it is transported to supply filling stations. Natural gas can be used in two different forms. 1. LPG (Liquefied Petroleum Gas). 2. CNG (Compressed Natural Gas).
- 8. Solar Energy Sun is considered to be the king of the biosphere and our ecosystem. It is an inexhaustible source of enormous energy. It radiates its rays all round the universe in all directions. Solar energy is received in the form of cosmic radiations. Thermal conversion occurs by direct heating and photo conversion is an indirect conversion.
- 9. Hydro Electric Energy Hydro power is the cleanest, cheapest & best source of electricity generation. It falls under the conventional energy resource. Energy is derived from fast flowing water. Hydropower converts power of the falling water to electric power which can be transmitted to long distances through wires & cables. It can be stored for future use also. Hydropower is generated by using hydraulic machine, called turbines. Now high dams are built to obtain a substantial amount of hydrostatic pressure.
