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.

Why is coal so bad for the environment?

The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion.

Why is coal a bad thing?

Asthma rates are skyrocketing in communities exposed to particulates from burning coal, and now one out of ten children in the U.S. suffers from asthma.

Why is coal the worst fossil fuel?

Of all fossil fuels, coal puts out the most carbon dioxide per unit of energy, so burning it poses a further threat to global climate, already warming alarmingly.

Can coal be burned cleanly?

Coal cleaning by 'washing' has been standard practice in developed countries for some time. It reduces emissions of ash and sulfur dioxide when the coal is burned. Electrostatic precipitators and fabric filters can remove 99% of the fly ash from the flue gases – these technologies are in widespread use.

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.

Why is coal so cheap?

Why is coal the worst energy source?

NASA scientist Jim Hansen has described coal as “the single greatest threat to the climate“. Coal contains more carbon than other fossil fuels such as oil and gas, resulting in the release of greater quantities of carbon dioxide into the atmosphere when it is burned.

Why is coal bad for the economy?
