Combustibles

Fossil fuels, including coal, oil, and natural gas, are energy sources formed from ancient plant and animal remains. Coal originates from land plants, while oil and natural gas come from marine plankton. These fuels store energy from the Sun, captured through photosynthesis by plants and marine life. Today, burning fossil fuels releases this ancient solar energy, powering modern electricity.
