Coalfired electricity generation is the process of making electric power from the energy (carbon) stored in coal. The process of converting coal into electricity has multiple steps: 1. A machine called a pulverizer (shown below) grinds coal into a fine powder. 2. The coal powder mixes with hot air, which helps it burn more efficiently.

Coal is the biggest single source of energy for electricity production and its share is growing. The efficiency of converting coal into electricity matters: more efficient power plants use less fuel and emit less climatedamaging carbon dioxide. This book explores how efficiency is measured and reported at coalfired power plants.

In most power plants, you need to spin a turbine to generate electricity. Coal, natural gas, oil and nuclear energy use their fuel to turn water into steam and use that steam to turn the turbine. Nuclear plants are different because they do not burn anything to create steam. Instead, they split uranium atoms in a process called fission.

Alternatively, electricity from natural gas may be derived by piping natural gas underground to power plants. Similar to the process with coal, the power plants burn natural gas to boil water to produce steam. The steam spins the blades of a turbine that are connected to a generator. The generator then spins magnets to generate electricity.

Most and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.
