Many U S coal beds are very near the ground's surface and about two-thirds of coal production comes from surface mines Modern mining methods allow us to easily reach most of our coal reserves Due to growth in surface mining and improved mining technology the amount of coal produced by one miner in one hour has more than tripled since 1978
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 fired power plants follow the Rankine cycle in order to complete this process Since they require plenty of water to be circulated in this cycle coal power plants need to be located near a body of water The process of coal fired plants can be seen below in Figure 3
