Explain the benefit and drawbacks of using coal for energy
Benefits of using coal for energy:
1. Abundant and reliable source: Coal reserves are found in many countries making it a reliable source of energy.
2. Cost-effective: Coal is relatively inexpensive compared to other sources of energy.
3. Jobs creation: Coal mining industry provides employment opportunities for many people.
4. Energy security: Countries that rely on coal as a source of energy are less vulnerable to fluctuations in gas and oil prices.
Drawbacks of using coal for energy:
1. Environmental pollution: The burning of coal releases greenhouse gases, including carbon dioxide, sulfur dioxide, and nitrogen oxides, which contribute to climate change and air pollution.
2. Health hazards: Coal mining and coal-burning power plants release harmful pollutants into the air and water, which can cause respiratory and other health problems.
3. Nonrenewable: Coal is a finite resource, and the demand for energy is increasing exponentially, which means that it will be depleted eventually.
4. Mining accidents and fatalities: Coal mining poses a risk of accidents and fatalities, including explosions, collapses, and cave-ins.
5. Habitat destruction and ecosystem degradation: Coal mining can degrade or destroy natural habitats, including forests, rivers, and wetlands.
