This heat is basically the thermal energy stored inside the Earth's core and the Earth's crust acts like an insulator and keeps the heat trapped inside. This thermal energy is known as geothermal energy. (geo=earth and thermal=heat). This energy is estimated to be one or two orders larger than all the energy recoverable from nuclear sources.
The current dominant design is a pulverizedcoal (PC) unit, in which coal is ground via a pulverizer to a fine powder and then combusted in a units are the most prevalent technology in the coal EGU fleet and represent about twothirds of the current units progressing and under construction (Shuster, 2011).
