What can we use instead of coal for electricity?

As incomes continued to rise, however, coal was slowly replaced with more efficient, convenient, and less polluting fuels such as oil, nuclear energy, natural gas, and, more recently, renewable energy.

What are disadvantages of coal?

The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.

Is coal still being formed?

How many years will coal last?

In order to project how much time we have left before the world runs out of oil, gas, and coal, one method is measuring the R/P ratios — that is the ratio of reserves to current rates of production. At the current rates of production, oil will run out in 53 years, natural gas in 54, and coal in 110.

Why is coal so bad?

Several principal emissions result from coal combustion: Sulfur dioxide (SO2), which contributes to acid rain and respiratory illnesses. Nitrogen oxides (NOx), which contribute to smog and respiratory illnesses. Particulates, which contribute to smog, haze, and respiratory illnesses and lung disease.

What is the real source of energy of coal?

Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun.
