Fossil fuels
Formation of Fossil Fuels
- Fossil fuels including coal, oil and natural gas are formed from the fossilised remains of prehistoric plants and animals.
- The process takes millions of years, during which heat and pressure transform these remains into carbon-rich energy sources.
Extraction and Use of Fossil Fuels
- Fossil fuels are extracted from the earth through processes such as mining (for coal) and drilling (for oil and gas).
- They are then processed and burned (combusted) to generate power, producing a large amount of energy.
Environmental Impact
- Burning fossil fuels releases greenhouse gases, like carbon dioxide, contributing to climate change.
- They also release harmful pollutants like sulphur dioxide and nitrogen oxides that can lead to air pollution and acid rain.
Non-Renewable Nature
- Fossil fuels are non-renewable resources, meaning once used, they cannot be replenished.
- The world’s fossil fuel reserves are finite and are being depleted at a rapid rate.
Alternatives to Fossil Fuels
- To mitigate the damaging environmental effects and future scarcity of fossil fuels, alternatives such as renewable energy sources and nuclear power are being explored and utilised.
- Increasing the efficiency of energy use and adopting more sustainable living practices are also means to reduce dependency on fossil fuels.
