►Geothermal energy: The word geothermal comes from the Greek words geo (earth) and thermal (heat). So, geothermal energy is heat from within the earth. We can use the steam and hot water produced inside the earth to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the water is replenished by rainfall and the heat is continuously produced inside the earth. Geothermal energy is generated in the earth's core, about 4,000 miles below the surface. Temperatures hotter than the sun's surface are continuously produced inside the earth by the slow decay of radioactive particles, a process that happens in all rocks. Probably the most
uncontrollable energy source that we have at our partial disposal is
the tremendous energy beneath the earth's crust. The center of our
planet is composed of molten Iron core which accounts for our
magnetic field that emanates from the earth's core. This enormous
source of thermal energy comes bubbling up to the surface in the
form of hot water springs or the super heated steam geysers that
erupt gently in clockwork fashion. The eruption of volcanoes is one
source that we have not been using, the eruption of Mount St.
