When you burn oil and coal, it emits carbon dioxide (CO2) and nitrogen oxides (NOx) along with different amounts of sulfur dioxide (SO2) depending on where it was mined. Carbon dioxide is a greenhouse gas, which means emitting it depletes the ozone layer, putting Earth at risk.
Burning oil and coal also releases energy. That is why they are energy sources.
Oil generally burns hotter than coal. This is because the carbon content in oil is higher than that in coal, resulting in a more efficient combustion process and higher heat output.
When coal is burned without oxygen, it undergoes a process called pyrolysis where it decomposes into volatile gases, tar, and char. This can produce useful byproducts such as charcoal and coal gas, which can be used in various industrial processes.
Burning coal, oil, and gas produces carbon dioxide, a greenhouse gas that contributes to climate change, as well as other air pollutants like sulfur dioxide and nitrogen oxides that can cause harm to human health and the environment.
Oil generally burns at a similar temperature to gas, but hotter than coal. The burning temperature can also depend on the specific type of oil or gas being used.
People burn coal and oil as sources of energy because they are relatively cheap and plentiful. They produce high amounts of energy when burned, making them suitable for use in power plants and vehicles. However, burning coal and oil releases pollutants into the atmosphere, contributing to air pollution and climate change.
Coal and oil

because it is
they burn fossil fuels like coal, fuel oil, and oil shale
because crude oil and gas are cleaner to burn
Coal is less expensive than oil and will be more plentiful in years to come

Fossils are mostly minerals, so unless they are very high in carbon, such as coal, they will not burn.
When humans burn fossil fuels (coal, oil and natural gas) they release carbon dioxide (CO2). This is one of the greenhouse gases which is causing global warming and climate change. This burning of fossil fuels happens in industry, transport and the generation of electricity.
