Fossil fuels such ascoaland oil is used to generate heat. This heat converts water into steam at very high temperature and high pressure. This steam at high pressure drives a steam turbine. Therotating shaft of the steam turbineis coupled to the armature of the alternator to generate electric...

When a conductor is placed in a changing magnetic field, the electrons in the conductor move, generating an electric current. Magnets produce such magnetic fields and can be used in various configurations to generate electricity. Depending on the kind of magnet used, a rotating electric generator ...
Why is coal so important? It lights houses, buildings, and streets; provides domestic and industrial heat; and powers most equipment and machinery used in homes, offices and factories. Coal isthe most abundant source of electricity worldwide, currently providing more than 36% of global electricity...
truck or train. These power stations need huge reserves of coal to produce electricity on a constant basis. The coal powered station uses coal to produce steam. The steam is then used to move the turbines that generate electricity. The biggest demand for coal today is from electric power ...
Petroleum companies are also developing alternatives in addition to more traditional forms of drilling. They includenon-hydraulic fracturingthat can penetrate rock without creating large volumes of wastewater. Renewable energies such as wind and solar power can also be used to generate electricity without...
Is it possible to generate electricity directly from heat? Why is it that some appliance plugs have three prongs and others have only two? Are fluorescent bulbs really more efficient than normal light bulbs? More Great Links Theater of Electricity ElectricityForum.com U.S. DOE: Electricity PG&E...
This venture into bioethanol production marks a significant shift from traditional steelmaking processes. In a typical blast furnace, coal is used to chemically reduce iron ore into iron, which is then processed into steel. This method releases substantial amounts of greenhouse g...
Based on these results, CO2-EOR where the CO2 is sourced from a coal-fired power plant provides one potential means for addressing the energy demand–climate change conundrum, by simultaneously producing electricity and oil to meet growing energy demand and reducing GHG emissions to abate global ...
