Does coal have a future?
At least 28 countries have now joined the alliance, which requires OECD signatories to end coal by 2030, and developing ones by 2050. Rising carbon prices and the shift towards gas as a low-carbon ‘transition fuel’ are contributing to coal’s decline, but the collapsing cost of renewables is the real game changer.
What is one more advantage of coal?
Coal is so affordable that virtually everyone would be able to get it. But not only is it cheap per ton, also a ton could produce a lot more energy than the same amount of any other fossil fuel. If you are wondering about clear renewal sources of energy such as wind or solar power, coal has an advantage over those too.

What are the disadvantages of using 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.
What are the advantages and disadvantages of using coal?

Will coal ever go away?
Although GlobalData also predicts that 100 projects will close worldwide, the company anticipates a total annual coal production increase of 1.3 percent over the next four years, which follows a modest growth of 2.8 percent in 2017 and 0.1 percent in 2018. …
What can we use instead of coal?
According to the National Aeronautics and Space Administration (NASA), nuclear power is the most effective substitute to challenge fossil fuels for future energy consumption. Compared to coal, gas, oil, and ethanol, nuclear power produces almost negligible adverse climate effects.
Does coal pollute?
Coal impacts: air pollution When coal is burned it releases a number of airborne toxins and pollutants. They include mercury, lead, sulfur dioxide, nitrogen oxides, particulates, and various other heavy metals.
Why is coal 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.
