Two disadvantages of using coal for electricity generation are:
-
Environmental Impact: Burning coal releases a significant amount of carbon dioxide (CO2), a major greenhouse gas contributing to climate change. Additionally, coal combustion produces other harmful pollutants, such as sulfur dioxide (SO2) and nitrogen oxides (NOx), which can lead to acid rain and respiratory problems in humans.
-
Resource Depletion and Habitat Destruction: Coal mining can result in substantial land degradation, including deforestation and habitat destruction. Surface mining techniques, such as mountaintop removal, can severely impact local ecosystems and biodiversity. Furthermore, coal is a finite resource, and as reserves deplete, extraction becomes more challenging and environmentally damaging.
