What is the primary use of coal?

Coal is primarily used for electricity generation due to its ability to produce high amounts of energy when burned. This process involves converting the chemical energy stored in coal into thermal energy, which is then used to generate steam that drives turbines, producing electricity. The combustion of coal accounts for a significant portion of the world's electricity generation, making it a crucial resource in energy production.

While coal has other uses, such as providing heat for homes and being a resource for industrial processes (like the production of steel), its dominant role remains in electricity generation. The shift towards renewable energy sources is gradually decreasing coal's share in electricity production, but it still stands as a prominent energy source globally.
