Geo Thermal Research Paper
From the Greek roots geo, meaning earth, and thermos, meaning heat is thermal energy
stored in the Earth. Thermal energy is energy that determines the temperature of matter.
Earths geothermal energy originates from the original formation of the planet, from
radioactive decay of minerals, from volcanic activity, and from solar energy absorbed at
the surface. The geothermal gradient, which is the difference in temperature between the
core of the planet and its surface, drives a continuous conduction of thermal energy in the
form of heat from the core to the surface. Geo thermal energy is mostly based on the place
that you set it up on and the type of weather that it is. The weather is a big factor because
you need steam and people rely on that to work.
The process of Geo thermal is as follows on how to set it up and how it works. From hot
springs, geothermal energy has been used for bathing since Paleolithic times and for space
heating since ancient Roman times, but it is now better known for electricity generation.
Worldwide, about 10,715 megawatts (MW) of geothermal power is online in 24 countries.
An additional 28 gig watts of direct geothermal heating capacity is installed for district
heating, space heating, spas, industrial processes, desalination and agricultural
applications.
There are pros and cons to having geo thermal as your main source of energy. Geothermal
power requires no fuel, and is therefore immune to fuel cost fluctuations, but capital costs
