Energy: Renewable and non-renewable sources of energy

Concept of Energy, A brief introduction to various renewable and non-renewable source of Energy. Advantages and Disadvantages were also discussed

1. Energy : Renewable and non-renewable sources of energy . Presented by - Papari Deka Roll No.-03

2. Energy may be defined as the capacity to do work. Energy is intimately related to power. Energy is the amount of force or power when applied can move one object from one position to another. Energy are broadly classifies into two main groups- 1)Non renewable energy source 2) R enewable energy source

3. Non-renewable energy source A non-renewable energy resources are the type of resources which once depleted cannot be replenished in a short duration. It cannot be used again and again.One day it will be exhausted. Non-renewable sources are not environmental friendly and have serious affect on our health.

4. Non-renewable energy sources : Coal Natural gas Oil Nuclear energy

5. Advantage: Available in highly concentrated form. Easy to store and transport. Reliable supply and they have high energy density. Disadvantage: Highly polluting. High running cost. A fossil fuel contribute to global warming . Its residual products are generally non-biodegradable. It produces greenhouse gases. Responsible for acid rain.

6. Renewable energy: Renewable energy is energy which is inexhaustible; generated from natural sources such as sun,wind , rain,tides and can be replenished again and again even after its usage and consumption . This can be renewed over relatively short period of time .

7. The five major renewable energy sources are- 1)Solar energy 2)Wind energy 3)Hydropower energy 4)Biomass energy 5)Geothermal energy

8. Advantage: Low pollution. Free of cost. Available in nature. A very large amount of energy could be generated in this way. Disadvantage: Usually produced in small quantities. Often very difficult to store. High cost of harvesting enery .

9. Why to conserve? We have limited fuels available on earth. Our demand for energy is increasing day by day. It is possible that someday ,most of the fuels will be exhausted and we will have to switch over to alternate energy. Once it is used,it cannot be formed again.As Petroleum once used cannot be renewed again.

10. Energy efficiency: About 82 % of the commercial energy consumed in the world comes from non-renewable energy resource. The remaining 1 8% comes from renewable energy resource. India now at 5 th global position for overall installed renewable energy capacity.

11. India would reach target of 175GW renewable energy generation by 2022. India to have 60% renewable energy by 2030,says Power minister. India is set to achieve 450 GW of renewable energy installed capacity by 2030,the Ministry of New and Renewable Energy said on 12 October 2021.
