How Does a Coal Power Plant Work?

Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

Coal - Wikipedia

The largest and most long term effect of coal use is the release of carbon dioxide, a greenhouse gas that causes climate change and global warming. Coal-fired power plants were the single largest contributor to the growth in global CO 2 emissions in 2018, 40% of the total fossil fuel emissions. Coal mining can emit methane, another greenhouse gas.
