Fossil fuels are obtained from the decomposition of organisms and plants that lived millions of years ago. These fuels include oil, coal, and natural gas.
They are a non-renewable source of energy and are widely used in electricity generation, transportation, and heating.
However, their combustion releases large amounts of carbon dioxide and other greenhouse gases, contributing to global warming and climate change.
Therefore, it is important to seek more sustainable and clean alternatives in the energy sector.
