Geothermal energy is defined as "Energy that is generated by converting hot water or steam from deep beneath the Earth’s surface into electricity."
Geothermal energy has a great deal of promise as the world looks toward expanding into more environmentally friendly energy sources.
http://geothermal-profits.com/ is a good site for geothermal industry news, particularly from an investment angle.

A very basic and simple answer is Geothermal energy is energy that exists in nature as a result of heat from the Earth's core. The Earth's core lies nearly 6000 km below the surface and holds temperatures that near 5000ºC.

"Geo" means Earth.
"Thermal" means heat.
So geothermal energy is heat energy from the Earth.
Volcanoes, hot springs, and geysers are the most common examples.
There are experiments being done to see if the heat of the lower crust and mantle can be tapped for heat energy as well.

Is the heat pulled from the earth's magma with help of a fluid, usually water which is returned to the surface in form of steam at high pressure, this moves the turbine of an electric generator

Energy extracted from earth's core....
Heat generated in earth's core is converted into required energy -- eg:-electricity -Heat from core is used to convert the water into steam which helps in rotation of turbines..

This is energy derived from the Earth's heat that is naturally generated underground.
