To live a thriving and comfortable life, electricity is a vital resource for humans. Our daily life depends on electricity. There are thermal power plants, where electricity is produced with the help of natural and non-replaceable resources like coal and fossil fuels. Today, water and wind are used to generate electricity. Not only this, but even the number of solar power plants is also increasing at a fast rate. Natural and non-replaceable resources are limited and are reducing day by day. To replenish these reserves, we may need millions of years. This is why it is important to use electricity in a careful manner and try to save more and more if we can.
