From coal in stockings to coal for energy

Coal burning with orange flames

In the 16th century, St. Nick's counterpart, Krampus, was fictitiously known to gift naughty children coal in their stockings. By the early 1900s, coal grew in popularity as a gift, since many families used coal to heat their homes. While today most of us no longer receive coal in our stockings, it still plays an essential role in Illinois' energy sector. Illinois coal mines account for 6% of the U.S. total coal production and 15% of the nation's recoverable coal reserves. Six states hold the majority of demonstrated reserves of coal, and Illinois is ranked second only to Montana.  
 

Illinois has 26 total coal mines, most of which are located in the southern part of the state. The geological makeup of the land plays a significant role in shaping our resource utilization, offering a substantial advantage as the nation's fourth-largest coal producer. Illinois has been able to mine coal for many years because coal deposits underlie approximately two-thirds of its area. 

 

Why is coal important to us? 

Historically, coal was used in various industrial, transportation, and commercial sectors. Today, we utilize coal primarily to generate electricity. Second to nuclear energy, coal-fired power plants were the highest electricity providers in Illinois from 2009 until 2023. Coal's contribution to the electric grid shifted considerably from 46% of electricity net generation in 2009 to 15% in 2023. This change occurred in response to stricter emission regulations and economic pressures. About one-fourth of the coal we mine is exported to other countries, and some is sent to 11 different states to help generate electricity. 

 

Why is coal a popular energy source? 

Coal is globally abundant, with enough supply to last for another 400 years. Its availability allows for quick utilization in electricity generation. Furthermore, coal is a cheap resource and relatively simple to transport.   

 

What else should I know about coal? 

Coal is a natural resource but is nonrenewable. While it may be a viable energy source for today, once all the coal has been utilized, it cannot be readily replaced. It is also vital to point out the environmental impacts of burning coal. Coal is well-known for gas emissions and health risks that arise from pollution when burned as a fossil fuel for energy. For example, sulfur dioxide, nitrogen oxides, and particulates can lead to respiratory illnesses. Mercury and other heavy metals released from burning coal are linked to developmental harm in humans and wildlife. The effects of coal combustion on our health are evident, and it also impacts the environment by adding carbon dioxide to the atmosphere and increasing greenhouse gases. Additionally, coal mining leads to the destruction of natural habitats, including forests, prairies, and other local ecosystems.  Even after mining has ceased, it can take decades for wildlife and vegetation to recover and return to their original habitat conditions.   

 

Coal is one resource we utilize for energy.  The current challenge is to develop new technologies and renewable resources that are cost-effective and reliable, enabling us to live in healthy environments. Regardless of whether you receive coal in your stockings, hopefully you now know a bit more about coal in Illinois.
