Had you ever thought that if energy can neither be created nor be destroyed, then why we need to conserve energy sources.
This is because any sources of energy we use to do work, is consumed and cannot be used again.
We know that energy comes in different forms and one form can be converted into another. For example, when we burn a candle, chemical energy of wax is converted into heat energy and light energy.
What is a good source of energy?
