With increasing demand for energy and with fast depleting conventional sources of energy such as coal, petroleum, natural gas, etc. the non-conventional sources of energy are gaining importance. This energy is abundant, renewable, pollution free and eco-friendly.
What is the importance of non conventional energy sources in the context of present energy scenario?
Natural resources like wind, tides, solar, biomass, etc generate energy which is known as “Non-conventional resources“. These are pollution free and hence we can use these to produce a clean form of energy without any wastage.
Why are non conventional sources of energy preferred nowadays?
here is your answer : 1) Non – conventional sources of energy are preferred over conventional sources of energy because non- conventional sources don’t exhaust so, they can be used in future but the conventional sources of energy once used up cannot be gained back and the future generations will suffer……
How non conventional sources are useful?
Non conventional sources of energy include solar, wind, tidal, geothermal. bio gas etc. They are relevant because : … Use of non conventional sources of energy is in tune with objective of sustainable development as it does not cause environmental hazards.
What is the importance of non conventional source of energy?
What is the importance of the non-conventional source of energy? Non-conventional sources of energy are considered to be important as they are renewable, pollution-free, availability of them is in abundance, and they are environmentally friendly.

What is the importance of alternative energy?
Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Creating economic development and jobs in manufacturing, installation, and more.
What are the examples of non-conventional sources of energy?
Nonconventional energy sources (also called alternative energy sources) are any sources or substances that can be used to produce fuels, other than conventional fuels. These are sources that are continuously replenished by natural processes, including biomass, hydropower, nuclear power, solar energy, and tidal energy.
What do you mean by non-conventional energy sources?
Renewable energy sources also called non-conventional energy, are sources that are continu- ously replenished by natural processes. For example, solar energy, wind energy, bio-energy – bio-fuels grown sustain ably), hydropower etc., are some of the examples of renewable energy.
Why do we need non-conventional sources of energy in Class 8?
Solar energy is an inexhaustible and non-polluting form of energy. … A device called a solar panel is used to convert solar energy into heat and electrical energy. A solar panel is made up of a number of solar cells that absorb solar energy and convert it into electricity.
What is non conventional?
: not conventional : not conforming to convention, custom, tradition, or usual practice : unconventional nonconventional teaching methods nonconventional energy sources Ten years ago, the alternative press was hard to find but easy to define.
Is coal non conventional sources of energy?
Fossil fuel, CNG, coal, oil, natural gas are the examples of the conventional sources of energy. Solar Energy, Wind Energy, Bio Energy, Hydro Energy, Tidal Energy, Ocean Energy are the examples of non-conventional energy resources.
What are the conventional sources of energy?
Conventional energy sources such as natural gas, oil, coal, or nuclear are finite but still hold the majority of the energy market. However, renewable energy sources like wind, fuel cells, solar, biogas/biomass, tidal, geothermal, etc.
What are the advantages and disadvantages of non conventional energy sources?
(i)Non-conventional sources of energy are inexhaustible. They do not pollute the environment. (ii)Nuclear power is emits large amounts of energy. (iii)Non-conventional sources of energy are low cost and easy to operate.
What are the difference between conventional and nonconventional sources of energy?
Conventional sources of energy are the sources that are commonly in use since long time. Non-conventional sources of energy refers to the sources that are identified few decades ago. They can be exhausted due to over consumption. They cannot be exhausted.
