ADVANTAGES AND DISADVANTAGES OF COAL AS A SOURCE OF ENERGY

ADVANTAGES AND DISADVANTAGES OF COAL AS A SOURCE OF ENERGY




Coal is a type of organically formed sedimentary rock that is burnt to release energy. Coal comes from the remains of plants and animals that were buried for millions of years.

Thermal power is electricity that is generated from the burning of fossil fuels such as coal.

Despite global efforts to reduce the use of coal in the production of electricity, some countries still use coal as a source of electricity.

Countries that are still using coal to generate electricity include China, which produces 3785TWh, followed by India, Japan, and Germany.

ADVANTAGES OF COAL

  • More efficient in thermal generation of electricity than oil.
  • Most suitable in the smelting of iron.

The use of coal as fuel to generate electricity has a number of disadvantages as follows:

sulfur dioxide and heavy metals emitted by coal is harmful




Burning coal results in the release of sulfur dioxide and heavy metals into the atmosphere .

These compounds lead to many side effects, such as respiratory damage to humans.

Pollutants from the burning of fossil fuels have been linked to diseases like cancer and asthma in several scientific studies. 




leads to formation of acid rain

The burning of coal also results in the release of sulfur dioxide into the atmosphere.

Sulfur dioxide is linked to acid rain, that is, when sulfur dioxide cools in the atmosphere it forms water droplets.

If the sulfur dioxide is in large quantities, the water droplets reach a saturation point resulting in precipitation.

The rain that falls is called acid rain.

This type of rainfall is very harmful to the environment and to people.  




burning of coal contribute to global warming

The burning of coal is also linked to global warming. This is a situation whereby global temperatures go up.

Global warming also results in the rise of water in the sea, which might flood the settlements along the coast.

NEGATIVE EFFECTS OF GENERATING ELECTRICITY FROM COAL

coal is non renewable resources

Another disadvantage of using coal as fuel to generate electricity is that coal is a non-renewable resource.

Even if coal did not pollute and contribute to global warming, we would not be able to rely on them forever.




This is because coal is non-renewable, meaning they do not naturally replenish fast enough for humans to use forever.

Therefore the use of coal as a source of fuel to generate electricity is unsustainable since the amount of coal available is diminishing every day.

Usage of coal has declined due to:

  1. Discovery of other forms of energy such as petroleum.
  2. Exhaustion of old accessible mines.
  3. High cost of mining coal.




USES OF COAL

  • Fuel: for domestic heating
  • Source of power for driving steam engines in power stations to drive dynamos which produce thermal electricity.
  • Raw material: the two chief carbonation products are released in the process.
  • Coal far: used for making fuel, oils, disinfectants, antiseptics, air line dyes (plastic performs) etc
  • Benzole: used to make motor spirit, weed killers, aspirin, saccham and sulphonamide drugs
  • Sulphate: of ammonia: used to make fertilizers insecticides, soap, explosives and chemicals for use in refrigerators.




Coal is a widely available and relatively inexpensive source of energy that has been used for centuries. It has played a significant role in the development of many countries, providing jobs and income to local communities. However, the use of coal also has significant environmental impacts, including air pollution, water pollution, and climate change. The burning of coal releases greenhouse gases, which contribute to global warming and climate change.

Additionally, the mining and transportation of coal can have negative impacts on local communities and the environment. As a result, many countries are now moving towards cleaner and renewable energy sources, such as solar and wind power. The use of coal as a source of energy is likely to decline in the future as the world moves towards cleaner and more sustainable energy sources. While it may be a significant source of energy for now, it is important to consider the long-term impacts of using coal and to develop plans for transitioning to cleaner and more sustainable energy sources.
