- 2. Energy • Energy is the capacity of a physical system to perform work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, electrical, or other forms. Sources of Energy: 1. Conventional Energy Sources 2. Renewable/Non-Conventional Energy Sources

- 5. Global Electricity Generation by various sources The global electricity generation mix in 2018 Compared to what it could be in 2040 under two possible scenarios are shown in these pie charts. The International Energy Agency’s (IEA’s) “Stated Policies” scenario factors in current and already announced policies, whereas the “Sustainable Development” scenario is fully aligned with the Paris Agreement, which has an objective of holding the increase in the global average temperature to well below 2C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5C.

- 7. Conventional Energy Sources • Conventional energy sources are the traditional sources of energy like coal and petroleum. Conventional energy sources are finite. They will not last forever. Non-commercial energy sources Generally, the energy sources that are freely available are considered as the non-commercial energy sources. The examples of non-commercial energy sources are, Straw, dried dung, firewood. Commercial Energy Sources The coal, electricity and petroleum are known as commercial energy since the consumer needs to pay its price to buy them. https://byjus.com/physics/conventional-and- nonconventional-sources-of-energy/

- 9. Natural Gas • Natural gas in its purest form is pure methane but before it is refined, it also contains varying amount of ethane, propane, butane and carbon dioxide. When refined, it is colorless and odorless but can be burned to release large amounts of energy. https://geology.com/articles/natural-gas-uses/

- 11. Coal • Coal releases large amounts of energy when it is burned because of the density of hydrocarbons in the material. • Coal is formed by dead plants being put under significant pressure and temperature for millions of years. • There are four grades of coal: lignite, sub- bituminous, bituminous coal and anthracite. • Bituminous coal is the best for releasing energy and is the most commonly mined type of coal. https://www.bombaytesthouse.com/ coal_coke_and_solid_fuels.html

- 14. Petroleum • Petroleum is formed from the compression of animal and plant remains over millions of years. Petroleum has to be drilled for because it is usually located deep below the earth's surface and is then refined to produce a number of different products including gasoline, heavy fuel oil and diesel fuel. https://www.shutterstock.com/search/oil+well+ diagram

These two words have the same meaning, with the only difference being in the places where the words are used. The term 'petrol' is used in UK, India and a few other places, while 'gasoline' or 'gas for short' is used in the United States.
