Explain the benefit and drawbacks of using coal for energy

Answer 1

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.
