The global decline in the use of coal as a source of energy is due to the availability of cheaper and cleaner energy sources. Coal has traditionally been a primary source of energy for many countries, but in recent years, the development of renewable energy sources like wind and solar, as well as the increased use of natural gas, has made coal less economically competitive. Additionally, the negative environmental impacts associated with coal, such as air pollution and greenhouse gas emissions, have made it less attractive as a source of energy. As a result, many countries are investing in cleaner and more sustainable energy sources, which has led to a decline in the use of coal.
