(f) The forms of energy which do not produce smoke and carbon gases such as carbon dioxide or carbon monoxide are known as green energy.(g) Non-conventional energy resources are inexhaustible in nature and can be used in various forms again and again. For example, wind energy, tidal energy, solar energy, etc. are non-conventional energy resources. (h) Heat and light energy of Sun are used in solar energy devices.(i) Because of increase in population and usage of energy resources, there is a potential danger of limited reserves of conventional energy resources, such as coal, petrol, diesel, crude oil and natural gas, getting exhausted in future. Therefore, it will be better to maximise the use of non-conventional energy resources to remove the danger of extinction of conventional energy resources.
(1) Wind is the odd one out as it is a non-conventional energy resource. The rest are conventional energy resource.(2) A book kept on a table is the odd one out as no work is being done in this case. In rest of the cases, work is being done.(3) Petrol is the odd one out as it is a conventional energy resource. The rest are non-conventional energy resource.(4) Putting off the light when going out is the odd one out as it is one of the measures of saving energy. The rest involves wastage of energy.

Can you picture driving a car that is powered by water? Or one that is powered by the Sun? The fact is that you may have to become used to such outlandish thoughts. Conventional fuels are increasingly running out, while non-conventional energy sources are becoming our future. And, in order to run them, let us study more about non-conventional energy sources.
Conventional Sources of energy- The sources of energy that are in use for long periods of time by humans and once finished cannot be replaced quickly are called conventional sources of energy. For example Coal, petroleum, etc.
Non-Conventional Sources of energy- The sources of energy that are continuously replenished in nature and are widely available. They are called non-conventional because till now they are not used extensively in our daily life. These sources of energy also do not cause pollution. For example Solar energy from the sun, wind energy from the winds, tidal energy, Bio-gas, and so on.
The Sun is the ultimate source of energy on our planet and all other examples that are mentioned above are obtained either directly or indirectly from the sun. For example, the wind energy that we obtain from the winds and the winds are produced by the unequal heating of two different regions of the surface of the earth. Thus, we can use these sources of energy till our earth receives light from the sun, which is there for the next millions of years. This is also the reason why non-conventional sources of energy are also called renewable sources of energy as every day these energies are getting renewed in nature.
Non-conventional sources of energy, often known as renewable sources of energy, are energy sources that are continually renewed by natural processes. Non-conventional energy sources are not quickly depleted and may be created at a consistent pace for repeated usage.
Furthermore, these energy sources are less expensive and do not contaminate the environment or natural surroundings. They are also known as renewable energy sources since they may be created or created through natural processes at a rate greater than or equal to the rate at which they are used.
No, any source of energy cannot be totally pollution free. This is because the process of producing energy may not cause pollution, but the production of devices required may cause pollution. Like solar energy is green but the making of solar cells cause pollution. Likewise, nuclear energy may not cause pollution but the e-waste generated after the fission reactions are harmful and cause health hazards. Still, they are much cleaner than non-renewable energy sources like fossil fuels, coal etc. 2ff7e9595c
