These fuels, mainly Coal, Petroleum and Natural Gas, are extracted and burned to generate heat, electricity and mechanical energy. Their combustion releases energy but also produces carbon dioxide, a major greenhouse gas driving global warming and climate change.<\/span><\/p>\n<h2><b>Fossil Fuel Types<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Fossil Fuels are classified into major categories based on their physical state, origin and composition, each with distinct formation processes and applications.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Primary Types<\/strong>: Coal, Petroleum and Natural Gas are the three major Fossil Fuels formed from terrestrial plants or marine organisms under pressure and heat over millions of years.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Secondary Forms<\/strong>: Derivatives like Kerosene, Diesel, Gasoline, LPG and Petrochemicals such as plastics and synthetic resins are produced through refining and processing of crude Fossil Fuels.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Other Sources<\/strong>: <strong><a href=\"https:\/\/vajiramandravi.com\/current-affairs\/shale-gas\/\" target=\"_blank\">Shale Gas<\/a><\/strong> and Oil Sands represent unconventional Fossil Fuels extracted using advanced technologies like hydraulic fracturing due to deeper and complex geological formations.<\/span><\/li>\n<\/ul>\n<h2><b>Coal<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Coal is a solid Fossil Fuel mainly composed of carbon, formed from terrestrial plant material buried in swampy environments and transformed through Coalification over millions of years.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Types of Coal<\/strong>: Anthracite contains 80-90% carbon and is hardest; bituminous holds 60-80% carbon; lignite has 40-60% carbon and higher moisture; peat is the earliest stage with lowest carbon content.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Formation Process<\/strong>: Coal forms when dense vegetation in wetlands gets buried under sediments and undergoes compression and heating, gradually transforming into higher carbon forms through geological time.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Distribution<\/strong>: China holds about 12% of global reserves; USA is second largest;

applications.<\/span><\/li>\n<\/ul>\n<h2><b>Petroleum<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Petroleum is a liquid Fossil Fuel formed from marine organisms buried under sediments and transformed into hydrocarbons through heat and pressure, commonly called \u201cBlack Gold\u201d.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Formation<\/strong>: Dead marine organisms settled on seabeds, got buried under sediments and converted into crude oil under high pressure and temperature over millions of years.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Refining Process<\/strong>: Crude oil is refined into products like petrol, diesel, lubricating oil, paraffin wax and petrochemicals through fractional distillation in refineries.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Global Distribution<\/strong>: Major reserves exist in Middle East regions like Saudi Arabia, Iraq and Iran; also in USA, Russia and Venezuela due to ancient marine conditions.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Indian Scenario<\/strong>: Oil discovered in Digboi (1869); ONGC established in 1956; major fields include Bombay High, Gujarat, Assam and Krishna-Godavari Basin.<\/span><\/li>\n<\/ul>\n<h2><b>Natural Gas<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Natural Gas is a clean, gaseous Fossil Fuel primarily composed of methane, formed alongside Petroleum or independently in sedimentary rock formations.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Composition<\/strong>: Methane is the dominant component, making Natural Gas efficient and relatively less polluting compared to Coal and Petroleum based fuels.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Formation<\/strong>: Marine micro-organisms form organic rich mud, which transforms into kerogen and later into gas under temperatures of 90-160\u00b0C through geological processes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Distribution<\/strong>: Major global reserves are in Russia, Iran and USA; in India, reserves are around 450 billion cubic metres mainly in Bombay High, Assam and
