Before getting into knowing what are energy sources we must know what energy is. Energy is the ability to do work. Energy helps in powering business, manufacturing and transportation of goods and services. There are many different ways in which the abundance of energy around us can be stored, converted, and amplified for our use.
Energy comes in different forms heat, light, thermal, mechanical, electrical, chemical and nuclear energy. We all use energy for our daily work like when we walk, jump, eat food, drive car, play etc. Energy is stored in different ways and can be transformed from one type to another.
So, the energy sources from which we gain energy are classified broadly into 2 groups namely: Renewable and Non-Renewable (Fossil Fuels) There you go! Have fun!
