Some countries around the world still use coal as a household fuel, especially in rural or underdeveloped areas where access to alternative energy sources may be limited. Countries that continue to use coal for residential heating and cooking include China, India, Pakistan and some Eastern European countries.

 However, the situation may have changed since then, as many countries are actively trying to phase out coal due to its environmental and health impacts. References should be made to sources or more recent  updates on the current state of coal use as a domestic fuel in specific countries.  Afghanistan is one of the countries with a history of using coal  as a  fuel source, especially in rural and remote areas. Due to limited access to modern energy infrastructure, coal and other traditional fuels are often used for heating and cooking.

 It should be noted that the situation in Afghanistan is complex and subject to change, especially given the geopolitical and social developments that have occurred since then. If you are looking for the most up-to-date information on energy sources in Afghanistan, I recommend that you consult reliable and up-to-date sources such as energy organizations, government agencies or international reports.
