Geothermal Energy

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 Energy? 

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 rock.

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 Energy.

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 Energy.

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 home.

The basic elements of the system include:

• Buried loops of piping (the ground loop);

• 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 reverse.

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 comprehensive manual and the most proven system on the market go to Alternative Energy Ways
