उत्तर
We should maximize the use of non-conventional energy resources because these resources are pollution-free and renewable sources of energy. Renewable energy is also known as non-conventional energy. Solar energy, wind energy, hydropower, and geothermal energy are some examples of non-conventional sources of energy. Therefore, it will be better to maximise the use of non-conventional energy resources to remove the danger of extinction of conventional energy resources.
