Source of All Geothermal Energy

Hello again,

It is important to remember that the sun is the source of all geothermal energy. NASA has some spectacular videos that give you a feel for the power of our sun! Try this video on for size (careful, it can be mesmerising). According to the leader on the video, this 15 minute video required about 150 hours of special technicians’ time to prepare. It is made from ten different wavelength exposures, each shown in different colours here, taken every 10 seconds.

P.S. If you get a white box with or without advertising in the middle of the screen, you can cancel it, Mouse-over the upper right corner area – when you see a small black circle with an “x” in it, click on it. That should close all the garbage and give you an unrestricted view. It is even more spectacular full screen!

Plug Pulled on St Gallen Geothermal Power Project

Switzerland: A highly touted geothermal project (electricity and district heating) in St. Gallen in the northeastern part of Switzerland has been terminated. SWI swissinfo.ch reports:

A plan in eastern Switzerland to supply geothermal electricity from underground heat has been axed. The city of St Gallen said there was not enough hot water to continue a project to build a power station using the renewable energy resource.   Read more …

From a realistic perspective, the project was a success – even thought it was an economic and political disappointment – in that it proved that the Molasse Basin hot water belt does not extend as far south as the Swiss border. Actually, there were a few boreholes sunk in southern Germany that also demonstrated the problem somewhat earlier. In those wells, the findings were that the formation that transported the hot water in the more northerly areas had been crushed to a certain extent in the southern regions, and the pores that allowed the water to flow in the north have been plugged further south by the small grains and dust of the crushings.

It was also a success in that the city managed an excellent public relations effort and sold a large percentage of the public on the project. In face of the technical failure of the project, one has to wonder if it will be possible to sell any such project in St. Gallen again in the next ten or fifteen years. On the other hand, it was an excellent example of how to sell such a project for other agencies in other locations in the future.

It is too bad that the project failed, since the geothermal types in Switzerland were really hoping for a positive result to enable them to replace at least some of the nuclear power that Switzerland says it one day will shut down.

Note: This is not really news, the project was terminated in May 2014, but we feel that a little separation from the emotions at the time have helped us make a more realistic report on the project.

Ground Heat Pumps

Geothermal Heat Pump – a green and cost effective technology

The word geothermal originates from two Greek words ageoa which mean earth and athermea which heat. Therefore it is a renewable source of energy emanating from the ground. A Geothermal heat pump works on the principal that in winters, it moves the heat from the earth into the home whilst in summers the apparatus discharges the heat of your home into the ground. Heat flows from higher temperatures substances to lower temperature substances and the earth traps as much as half the energy of the sun received by it. A ground source heat pump utilizes this energy stored in the earth or water bodies to provide heating. Ground source heat pumps use the earth as a source of energy in winters and as a heat sink in summers. A geothermal heat pump transfers the heat from the water to the air and thus it functions as an air conditioner.

As it relies on renewable source of energy a geothermal heat pump or ground source heat pump is much for efficient in heating and cooling the spaces and water than an electric heater is. This enables you to cut utilities bills by as much as 70%.

Using the relatively constant temperature of the ground several feet below the earth’s surface for heating and cooling, geothermal heat pumps are appropriate both for retrofit and new houses. A large number of geothermal companies and geothermal pump contractors are there and you can easily get a geothermal heap pump installed in your home.

The basic components of a ground source heat pump include a loop field, a liquid pump pack and a water source heat pump. The loop field can be placed on your home, enabling it to discharge heat into the ground or move the earth’s heat into your home. The size of the loop depends upon the size of the building. The liquid pump pack is used to send the water whilst the water source heat pump is more like a boiler.

What Is Geothermal

What is Geothermal Energy? - IGA International Geothermal Association

What is Geothermal Energy

The phrase “geothermal energy” has been around for hundreds of years. The term “geothermal” derives from the Greek words; geo (meaning earth), and therme (meaning heat). This instantly gives us the quick definition, “geothermal energy is heat from the earth”.

A common misunderstanding of geothermal energy lies in the source of this heat. The two sources which heat our earth are the earth’s core, and the sun.

The earth’s core is predicted to be between 3000 and 4000 degrees Celsius, and this heat warms the earth right up to the land beneath our feet, decreasing in temperature all the way.

The suns surface is approximately 5600 degrees Celsius. The heat from the sun only warms the first few meters of our earth, and then this heat is lost during the night.

So where does the misconception concerning geothermal energy actually come from? Well, many people believe that the fairly modern method of heating water by laying pipes under around 1 meter of earth, is geothermal energy. Many scientists disagree with this, as geothermal energy should be used to describe the heat energy dispersed by the earth’s core.

geothermal heating systems

The most recent hot technology in heating and air conditioning is the geothermal unit. Like heat pumps, the geothermal systems are used to cool down and heat houses, companies and other indoor spaces.

There are lots of refunds and tax motivations for installing these systems. Another great use for the geothermal system is with a pool. These systems will perform extremely well if properly designed for the climate. Those who live in an area like Arizona that has very hot summers, will be prepared to enjoy their pool for a longer period. This suggests that the geothermal heating and cooling system will be busy at work keeping your pool at the correct temperature for the weather going on outside. If you’re in the middle of a hot spell in the summertime, your system will simply manage the heat transfer and you are going to be able to take a dip in your pool and feel refreshed.

Geothermal systems use the solar electricity stored just under our feet to provide heat, air con and hot water. Every day the Earth is busy absorbing the heat of the sun as it beats on the surface. This heat energy that is kept in the ground is what geothermal units use to do their job. The reason behind that is that the many corporations that provide this type of system have been busy developing, testing, improving and installing existing technologies for the last two years to bring this product to the market.

The better part about the geothermal cooling and heating units is they are one of the most productive and comfy technologies available. You can feel happier about installing your new geothermal system and know that you’re doing your bit to help this Earth stay healthy.

Geothermal Cooling

Cool Your Home with Geothermal Energy

One form of alternative energy you can use to cool your home is geothermal energy. This might sound surprising, but you can actually use the energy found in your own backyard, by utilizing geothermal heat pumps. You can save up to 70% on cooling bills.

The bad news is that professionally installed geothermal systems are too expensive. The good news is that there are ways in which you can harness geothermal energy, to partially cool your house, without shelling out a fortune for it.

You might already be utilizing geothermal energy without realizing it. Northern state homeowners often use this renewable energy without their direct knowledge.

This article will teach you how to maximize the cool air that’s stored within your basement.

You need to have a basement, or at least some crawl space beneath your house, for this cooling method to work. You must be able to access the space from within the confines of your home. If the space has a small window or vent, this will help with the air flow. You’ll also need a small portable fan for this one.

The principle of geothermal cooling works this way. During hot summer days, the basement is cooler than most parts of the house. The basement’s exterior walls are controlled by the constant heat trapped a few feet underground, right beside the house’s foundation. The temperature penetrates the basement walls and cools the air trapped inside. You must then distribute the cool from this musty and damp air, throughout the rest of home.

The most efficient way of doing so is to cover your windows with shades or curtains during sunrise, to minimize the natural heating by the sun. During nighttime when the outside temperature falls below 75 degrees, open your upstairs windows while leaving your fan on, to suck in the cool air.

But, once the temperature get higher than 75 degrees, you can turn on your geothermal cooling system by opening one of the windows in the basement. You don’t need to fully open it. A small opening is enough just to let some air through. Be sure to close all other windows in your house except for one. That way, air flows through the open windows. The open window should be the highest one in your house. This will vent out the most hot air.

Your small fan should be turned on and should point toward the window. This should make the air from the basement move up to the open window, and let the hot air go out. It usually takes between thirty minutes to one hour to circulate the cool air from the basement to the rest of the house.

This method of utilizing geothermal energy might seem to involve lots of work. But your family and your finances will benefit from it in the long run. You’ll see your dependency on your air conditioner decrease, resulting in lower energy bills.
