Energy Resources | Class 6 | Geography | Chapter 9 | Maharashtra State Board
In this informative video, we will delve into the fascinating world of energy resources and their significant role in our daily lives. The vast array of energy resources is classified into various categories such as conventional-non-conventional, biotic-abiotic, renewable-non-renewable, substance-based-process-based, etc. In this lesson, we will focus on the last two classifications and explore the examples of substance-based energy resources such as wood, coal, mineral oil, natural gas, biogas, waste material, and atomic energy. Furthermore, we will also discuss the examples of process-based energy resources such as hydel power, wind energy, solar energy, tidal energy, and geothermal energy. Join us in this journey to discover the significance and usage of energy resources in our daily lives.
