Oil has overshadowed coal for several reasons:
-
Energy Density and Efficiency: Oil has a higher energy density compared to coal, meaning it produces more energy per unit of weight. This efficiency makes oil more versatile and preferable for transportation and various industrial applications, including petrochemicals and aviation fuels. The ease of transporting and storing liquid oil also contributes to its dominance over solid coal.
-
Cleaner Combustion: Oil generally produces fewer emissions of pollutants like sulfur dioxide and particulate matter compared to coal when burned. This makes oil a more attractive option for meeting environmental regulations and reducing air pollution, especially in urban areas where air quality is a significant concern.
These factors have contributed to the preference for oil in many sectors, leading to its prominence over coal in the energy landscape.
