Hint: We all are aware of the concept of energy as the measurement of power or the ability to do work. In our daily life, it plays an important role as a necessity in all fields, such as industry, transport, communication, sports, protection, household, agriculture, and more. There are many types of energy sources around us that create a certain energy and they are distinguished into conventional and non-conventional energy sources based on the availability of the sources and whether the sources are going to last forever.
Complete answer: There are two types of energy sources in the world. These sources are naturally formed and later manipulated by technology to provide an outcome. There are two types of energy sources; Conventional sources of energy and Non-conventional sources of energy.
Conventional energy sources are the sources that are limited in amount or available in small amounts, such as coal, petroleum and natural gas. They have been in use for a long time which will be over in a few years and most of these sources are found underground. Non-conventional energy sources, on the other hand, are abundant in nature. These will not be over in any time soon. Solar energy, wind power, tidal energy, biomass biogas are some examples of this.
Conventional energy sources are referred to as non-renewable sources of energy as they are exhaustible. They are not constantly replenished as they have been established for over a million years. Except for hydel power, they can be exhausted entirely due to over-consumption. Non-conventional energy resources are known as renewable resources. They’re constantly replenished by natural processes and over consumption doesn’t lead to their replenishment.
Conventional energy sources pollute the atmosphere and even lead to global warming by releasing toxic gases and In using and maintaining these sources of energy, heavy expenditure is involved. . But non-conventional energy sources are environmentally-friendly and do not pollute the atmosphere. They’re comparatively cheaper to use.
Note: Through natural processes, non-conventional energy sources can be substituted at a rate equal to or greater than the rate at which they are consumed. Owing to their persistent exploitation, conventional sources of energy resources have been largely exhausted. It is believed that in a few decades, the petroleum deposits in our country will be depleted and the coal reserves will last a hundred more years. As people are becoming aware of this situation, measurements have been taken by people to control the use of conventional energy sources and find non-conventional alternatives to them.
