Question

What is meant by green energy? Which energy sources can be called as green energy sources and why? Give examples.

Answer 1

Hint:Green energy is also known as renewable energy. The name renewable itself suggests green energy is the energy which can be renewed or replenished. Green energy is also known as clean energy. This is because it is less harmful to the environment compared to other forms of energy.


Complete solution:
We know that green energy is the energy which can be renewed or replenished. Green energy is also known as clean energy or renewable energy.
The energy which is obtained from the resources which do not deplete or replenish themselves is known as green energy. Green energy is opposite to the energy which is obtained from fossil fuels. Fossil fuels are depleting or non-renewable in nature.
Green energy is a source of clean and inexhaustible energy. Green energy does not cause pollution as it does not produce any greenhouse gases and polluting emissions.
The resources which produce green energy are known as green energy sources. These are natural sources. The green energy sources are the natural sources that replenish the depleted or consumed amount of sources within a finite interval of time through natural reproduction or other recurring processes.

Thus, as the green energy sources are named because they can replenish themselves. The examples of green energy sources are solar, wind, biomass, geothermal and water.


Note:Green energy reduces energy dependence on fossil fuels. Green energy is easily generated as its sources do not have any non-availability issues. Green energy is mainly used to generate electricity. Solar energy is used to heat and light homes, biomass is used to provide heat for industrial use.
