How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.

In its simplest form, a Power Plant, known also as a Power Station, is an industrial facility used to generate electricity. To generate power, an electrical power plant needs to have an energy source. One source of energy is from the burning of fossil fuels, such as coal, oil and natural gas. Then we also have nuclear power, and finally ...

An integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the electricity generation cycle. Some of these pollutants, such as sulfur, can be turned into reusable byproducts through the Claus process.

The magical science of power plants. A single large power plant can generate enough electricity (about 2 gigawatts, 2,000 megawatts, or 2,000,000,000 watts) to supply a couple of hundred thousand homes, and that's the same amount of power you could make with about 1000 large wind turbines working flat out. But the splendid science behind this amazing trick has less to do with the power plant ...
