Sources of Energy
Science Solutions from Chapter -1 - Sources of Energy
The chapter discusses the availability of energy and how it can be generated using various sources. Besides, sources of energy and their applications are mentioned. It also deals with the usage of energy sources in a controlled manner.
Practice Other Topics from Sources of Energy
In this topic, we will study the method to select a good or appropriate source of energy. It also comprises of various activities for better understanding of the concept.
This topic discusses conventional sources of energy which are fossil fuels (remains of plants and animals). Coal, petroleum and natural gas are some fossil fuels. These are the non-renewable sources of energy.
This topic describes that non-conventional source of energy is the energy radiated by the sun, i.e., solar energy. This energy is also used in cooking. Tidal energy, wave energy, ocean thermal energy, geothermal energy and nuclear energy are the other sources of energy.
This topic explains how the excessive use of sources of energy is leading to environmental degradation, such as burning fossil fuels and mining activities. Depletion of the Ozone layer is due to the use of CFCs in refrigerators. Global warming results from greenhouse gases.
