This organic matter originates from plants that absorbed sunlight during photosynthesis, highlighting a direct connection to solar energy. The initial step in coal formation occurs in swamp-like environments, where dead plant material accumulates.

Over time, these layers of plant material are buried by more sediments, leading to increased pressure and temperature. This transformation occurs over millions of years, with the resultant coal varying in carbon content, energy content, and other characteristics, known as rank. The major types of coal include lignite, sub-bituminous, bituminous, and anthracite, each signifying a different degree of metamorphosis. This intricate process underscores how ancient solar energy is stored and eventually utilized as a fuel source in modern times.

2. COAL AND ITS ENERGETIC TRANSFORMATION

The energy stored within coal can be traced back to the sun, making it a fascinating subject of study in the realm of energy production. When coal is burned, the chemical reactions occurring release energy trapped within its carbon structure, primarily via combustion which converts coal into heat and gas. This heat is harnessed for power generation through steam turbines or used for various industrial processes.

The energetic transformation of coal begins as the carbon within the coal reacts with oxygen. This process creates carbon dioxide and heat, which can be harnessed to produce electricity. However, despite the apparent utility of coal, the combustion process has significant environmental implications, resulting in greenhouse gas emissions and other pollutants. Therefore, while coal carries the solar energy originally captured by plants, its use raises critical questions about sustainability and long-term energy strategies.
