Two significant disadvantages of using coal for electricity generation are:
-
Environmental Pollution: Coal combustion releases a variety of harmful pollutants, including sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. These emissions contribute to air quality deterioration, acid rain, and respiratory problems among humans. Moreover, coal mining can lead to land degradation, water contamination, and biodiversity loss.
-
Greenhouse Gas Emissions: Coal-fired power plants are a major source of carbon dioxide (CO2), a potent greenhouse gas that significantly contributes to climate change. Compared to other energy sources, coal has a higher carbon intensity, meaning it emits more CO2 per unit of electricity generated, which exacerbates global warming and its associated impacts on ecosystems and weather patterns.
