Non-conventional energy resources are renewable. The main difference between conventional and non conventional sources of energy is that the former is non renewable and the later is renewable. Note: The conventional sources of energy are fossil fuel, CNG, coal, oil, natural gas.

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.

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.

(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.

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.

Although nuclear energy is considered clean energy its inclusion in the renewable energy list is a subject of major debate. The five renewable sources used most often are biomass, wind, solar, hydro and geothermal. Nuclear energy on the other hand is a result of heat generated through the fission process of atoms.

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.

The Disadvantages of Non-Conventional Sources of Energy

• Inconsistent, Unreliable Supply.
• Pollution.
• Harmful to Wildlife and Surrounding Environment.
• High Cost.
• Not Every Non-Conventional Energy Source Is Commercially Viable.
• Location-Specificity Means Lower Chances of Universality.
• Low Efficiency Levels.

The disadvantages to conventional energy resources indicate that once sources of non-renewable energies are gone they can’t be replaced or revitalized. The mining of non-renewable energy and the by-products they leave behind causes damage to the environment.

“It is also expected that the energy needs in the country could grow 5-7 times by 2030. So, in order to cope up with the rise in energy demands we need to sustain the economic growth rate at 8 per cent and explore new sources of energy like solar, wind, hydrogen and nuclear energy,” Choubey added.

What Are Limitations of Conventional Sources of Energy? – Environmental Studies

• Very Costly Production Cost.
• Heavy Transmission & Distribution Loss.
• Limited Reach.
• Big Threat for Environment & Public Health.
• Cause of Global Warming, Greenhouse Effect, Acid Rain Etc.

Difference Between Conventional and Non-conventional Sources of Energy

Answer. Energy generated by using wind, tides, solar geothermal heat and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environment pollution.
