How Does a Coal Power Plant Work? - Bright Hub Engineering

Dec 04, 2008 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. Learn how the process works as well as interesting

How Do Wind Turbines Work? | Department of Energy

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. Wind is a form of solar energy caused by a combination of three concurrent events:
