Chapter 14 – Sources of Energy

CBSE Class 10 Science Chapter 14 - Sources of Energy

Brief Information: Our energy requirements increase with our standard of living. In order to fulfil our energy requirements, we try to improve the efficiency of energy usage and also try and exploit new sources of energy. The chapter discusses different sources of energy and they are conventional sources of energy, which we keep on using for many years. It includes fossil fuels, thermal power plants and hydropower plants. The advantages and disadvantages are also discussed. After those improvements in the technology for using conventional sources of energy is also discussed such as Biomass and wind energy. Next, students will study the topic of alternative or non-conventional energy resources. It includes solar energy, in which energy is generated through the solar cell and solar panel. Energy can be generated from the sea such as Tidal energy, wave energy and ocean thermal energy. Energy can also be generated from the earth’s crust, known as geothermal energy. Nuclear energy is energy in the nucleus (core) of an atom. The energy source we select would depend on factors like the ease and cost of extracting energy from the source, the efficiency of the technology available for using that source of energy and the environmental impact of using that source. Many of the sources ultimately derive their energy from the Sun. All the topics are explained with the advantages and disadvantages of it.
