What are the advantages of using coal as an energy source in Australia?

If stored in cool, dry conditions, coal lasts indefinitely. Electricity produced from coal costs around $0.08 per kilowatt-hour. Compare this to a wood-burning stove, or heat provided by oil or gas, and coal is by far the most affordable.

What are the advantages of using coal in Australia?

The Australian economy continues to rely on coal as a source of affordable, reliable electricity. For example, coal supplied 68.6 per cent of electricity to the National Electricity Market in 2019, gas 9.1 per cent, hydro 6.7 per cent and other renewable energy (wind, solar farms and solar PV) 15.9 per cent.

What are the advantages of coal as an energy source?

❖ Coal is plentiful in many places and it is easy to access through mining, so people rely on it to produce energy. ❖ Coal is easy to store. Once it is mined it can be safely stored with no hazard of fire or explosion like there is with gas or oil. ❖ It is relatively easy and inexpensive to convert coal into energy.

In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.

What is a major disadvantage of using coal as a source of energy?

Coal pollution contaminates our water systems

Burning coal releases a host of toxic materials into the atmosphere, such as lead, sulfur dioxide, nitrogen oxides, and mercury. The mercury in air pollution caused by coal literally rains down into our lakes and rivers.

Why is coal good for the environment?

Coal supplies around 33% of the energy used for electricity in the United States, which makes coal-fired power plants a prime target for reducing greenhouse gas emissions (2).

What are 3 disadvantages of coal?

The burning of coal is not environmental friendly because it produces harmful byproducts and gas emissions such as sulfur dioxide, carbon dioxide and nitrogen oxide that causes pollution to the environment including acid rain. Coal energy is nonrenewable energy source.
