"Coal-fired" refers to power plants that generate electricity by burning coal. In this process, coal is combusted to produce heat, which then converts water into steam. The steam drives turbines connected to generators, producing electricity. These plants are a significant source of energy in many countries, but they also contribute to air pollution and greenhouse gas emissions. As a result, there is a growing shift towards cleaner energy sources, such as solar and wind power, to reduce environmental impacts and combat climate change.
