Coal is a type of rock that people burn to make electricity. It has been used for many years, and even today, it helps provide power to homes and businesses. When coal is burned, it creates heat. This heat is used to turn water into steam. The steam then spins a turbine, which generates electricity. This process is important because it helps keep the lights on and powers many things we use every day. Companies like Insun work hard to make sure coal power is safe and effective for everyone. While there are many ways to create electricity, coal remains a big part of energy production around the world.
