Which source contributes significantly to the emission of greenhouse gases?

Coal-burning power plants are a major source of greenhouse gas emissions. When coal is burned to generate electricity, it releases significant amounts of carbon dioxide (CO2), a primary greenhouse gas. In addition to CO2, the burning process can also emit other harmful substances like sulfur dioxide (SO2) and nitrogen oxides (NOx), which contribute to air pollution and can exacerbate climate change.

The reliance on coal for energy has historically been high due to its abundance and low cost, but this same reliance is a major driver of greenhouse gas emissions. Transitioning to cleaner energy sources, such as wind, solar, or natural gas, is essential for reducing the carbon footprint associated with electricity generation. This makes coal-burning power plants a central focus in discussions around climate change and emissions reduction strategies.

Other options listed, although they may contribute to environmental issues, do not have the same direct and significant impact on greenhouse gas emissions as coal combustion.
