The Pros and Cons.
by David Neich
Geothermal Energy is not as well known as a
type of energy compared to solar energy and wind
energy. Basically this is not as user friendly as the
forms of energy that I just listed before due to the nature of
collecting the energy
What is Geothermal
Geothermal energy is based on the words
(geo) meaning earth and (thermal) meaning heat, therefore heat
from the earth. This type of heat is tapped
into by drilling deep down into the earths core, even to the
point of miles down so far down to the magma or molten
There are several advantages to geothermal
heat compared to our traditional ways but it certainly
is on a major scale compared to the domestic level. It is
very much underutilsed at just 1% and is such a clean energy
source with it emitting hardly any green house gases.
Advantages to Geothermal
1. The amount we are using is at 1% it so
insignificant we could use it forever due the amount that is on
offer, we just need to tap into it.
2. The differences in what you can use it for is immense when
it comes to who can take advantage of it, single households
through to cities could use it, it is truly amazing.
3. If you set up a geothermal energy station and get it up and
running you don't have to do it again and you don't need
to pay for the fuel because it is free.
4. Geothermal plants can be built with emissions-controlling
systems that can inject these substances back into the earth,
thereby reducing carbon emissions to less than 0.1% of those
from fossil fuel power plants.
Disadvantages of Geothermal
1. Construction of the power plants that are going to
develop the energy is taking up a lot of land and the
resources that it takes to build the power plants, concrete and
all the clearing of the land.
2.The water from geothermal sources contains dangerous
chemicals including arsenic and mercury and potentially
contaminate local rivers and you would definately not be able
to drink that water, nor the fish would eatable.
3. After so many decades of use these locations will
eventually dry up and all the effort to construct them
will almost be a waste of time.
4. The obvious costs to do this for your own home is completely
not viable but some time in the future but don't hold your
breath. As you can see what it takes to develop this type of
technology is far from being available for the common home.
Geothermal energy is suitable
for our households, you can do it but there is certain
limitations, read through this part to understand more.
The following is an excerpt from Geothermal - Bringing
Comfort to Your World, a downloadable booklet from http://www.alliantenergygeothermal.com
A geothermal heating and cooling system,
sometimes called a ground-source heat pump, works on a
simple premise: the earth below the "frost line" (usually
about four feet down) is a constant temperature of about
50 degrees year round. Heat can be taken from the ground
and transferred through a heat pump to the air in your
home during the winter. Heat can also be transferred back
into the ground during summer to cool your
The basic elements of the system
• Buried loops of piping (the ground
• A biodegradable liquid antifreeze;
• A pump module to circulate the antifreeze; and
• A heat pump.
The loops of piping are buried in the ground, either
vertically or horizontally (more about that later) and are
connected to the circulating pump inside your home. The pump
module circulates a mixture of water and biodegradable
antifreeze through the buried pipe loops, and the liquid
mixture absorbs heat from the ground as it flows through the
loop. The heat pump takes heat from the liquid mixture and
transfers it to the air, which is circulated in your home. To
cool your home in the summer, the system simply works in

Do you think that it's feasible. The reality for
large-scale home geothermal production is a a fair way away, up
until then we certainly best to stick to our old friends, which
of course is solar energy and wind energy. The main point is
that you check things out and be informed.
Our recommendations are to get a program like the
ones we have reviewed in the Alternative
Energy Program Reviews section on this site.
You can do just about what you want to do with one of
those programs but if you want to get the most
