Fossil Fuels Introduction
Fossil fuels, including coal, oil, and natural gas, are concentrated organic compounds formed from ancient flora and fauna over millions of years through complex geological processes.
Abiogenic Origin Theory
Contrary to popular belief, some scientists propose fossil fuels aren't solely organic but are partially formed inorganically, from deep carbon deposits, challenging the traditional biogenic theory.
Coal's Varied Formation
Coal types vary by carbon content and formation period. Peat, lignite, bituminous, and anthracite coal reflect increasing carbon concentration and geological transformation intensity.
Oil Windows Discovery
Petroleum forms in 'oil windows,' specific temperature and pressure conditions suitable for oil genesis. Missing these conditions either halts formation or degrades the hydrocarbons.
Natural Gas and Radon
Natural gas often harbors radon, a radioactive gas. Radon's half-life allows dating of gas deposits, providing insights into the timing of formation and containment.
Fossil Fuel Environmental Cost
Fossil fuel extraction and use contribute significantly to environmental degradation, emitting greenhouse gases and harmful pollutants, leading to global warming and health issues.
Renewables vs. Fossil Fuels
Renewable energy sources are gaining traction, yet fossil fuels remain dominant globally. The energy transition faces challenges in infrastructure, storage, and energy density.
