Thank you for using GreenMatch. Geothermal energy is currently believed to be one of the most advantageous sources of energy. Not only is it a renewable type of energy but is also present in most areas, outperforming even some conventional sources in many aspects. Moreover, the first commercial geothermal power plant is planned to be built in Cornwall, UK if all the necessary funds are obtained. That should come as no surprise since some countries profit from the presence of geothermal energy on a large scale.
In fact, more and more households all around the globe are investing in geothermal energy and heating systems to cut their costs. First and foremost, geothermal energy is extracted from the earth without burning fossil fuels, and geothermal fields produce practically no emissions. Geothermal energy also has many advantages when compared to other renewable sources like solar, wind or biomass.
It is an exceptionally constant source of energy , meaning that it is not dependent on neither wind nor sun, and available all year long. Due to the fact that geothermal systems only have few movable parts which are sheltered inside a building, the life span of geothermal heat pump systems is relatively high. Heat pump pipes even have warranties of between 25 and 50 years , while the pump can usually last for at least 20 years.
Unfortunately, no matter its reputation of being an environmentally friendly alternative energy source, geothermal energy also causes some minor concerns in regards to the environment. The extraction of geothermal energy from the grounds leads to a release of greenhouse gases like hydrogen sulfide, carbon dioxide, methane and ammonia. However, the amount of gas released is significantly lower than in the case of fossil fuels.
Furthermore, despite being considered a sustainable and renewable energy, the chances are that specific locations might cool down after time , making it impossible to harvest more geothermal energy in future. The only non-depletable option is sourcing geothermal energy right from magma but the technology for doing so is still in the process of development. This option is worth the investment mainly thanks to the fact that magma will be around for billions of years.
Another disadvantage is the high initial cost for individual households. Nevertheless, the return on such investment is very promising, being able to earn the investment back within 2 to 10 years. In case of geothermal systems, having a piece of land next to the house is required in order to be able to install one.
That makes geothermal systems hard to be implemented for homeowners in big cities, unless a vertical ground source heat pump is used. There is a number of different geothermal systems available. Which system to choose depends on a variety of factors such as soil conditions, climate, local installation costs on site and available land.
There are two basic ground loop systems which further divide into several subgroups:. These systems differ mainly in the installation of the pipes, depending on the structure and size of the land available. After all this information on the pros and cons of geothermal energy, the core question remains: how much do you actually have to invest in order to get your own geothermal system up and running in your own home?
Even though geothermal systems are more costly compared to other heating or cooling systems, they have much lower operating costs and deliver more energy per unit. It is believed that costs for the implementation are likely to be reduced further in the future. However, the amount of such aid depends on many factors, like the house size, location, roof type, current heating system, etc. As the shallow ground temperatures from which geothermal energy is taken are relatively constant, geothermal heating systems can be used almost everywhere.
However, the characteristics of the land decide which systems might be more favorable, and needs to be determined by your supplier and installer. Composition and properties of soil and rock can affect heat transfer rates and therefore need to be taken into consideration for designing geothermal systems. Ground and surface water influence the type of ground loop, as well as groundwater can be used as a source for open-loop system, if the water quality is sufficient. The size and layout of the land, landscaping, location of sprinkler systems, etc.

Geothermal HVAC Green Heating and Cooling
It uses the earth all the time, without any intermittency , as a heat source in the winter or a heat sink in the summer. This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solar heating to form a geosolar system with even greater efficiency. They are also known by other names, including geoexchange, earth-coupled, earth energy systems. The engineering and scientific communities prefer the terms " geoexchange " or " ground source heat pumps " to avoid confusion with traditional geothermal power , which uses a high temperature heat source to generate electricity. Like a refrigerator or air conditioner, these systems use a heat pump to force the transfer of heat from the ground. Heat pumps can transfer heat from a cool space to a warm space, against the natural direction of flow, or they can enhance the natural flow of heat from a warm area to a cool one. The core of the heat pump is a loop of refrigerant pumped through a vapor-compression refrigeration cycle that moves heat.

Advantages and Disadvantages of Geothermal Energy - The Source of Renewable Heat
Energy geostructures are a modern application of low enthalpy geothermal systems i. The principle consists in setting up a network of pipes inside the reinforcement cages inside the concrete structures. A heat transfer fluid, which circulates in the pipe network, exchanges heat with the ground through the concrete. A heat pump adapts the temperature from the ground to that required to heat or cool buildings. The efficiency of the system must meet both energy heat or cold production and geotechnical-structural limited additional stresses and displacements criteria, which are highly dependent on the local conditions of the site hosting the construction.

Virtually pollution-free, inexhaustible, safe and efficient, geothermal energy is a truly clean means of heating and cooling that is also dependably constant. According to a report by the National Wildlife Federation, campuses in 42 states use geothermal energy for heating and cooling. Thanks to geothermal technologies like heat pumps, campuses can use the heat of the earth to:. Low Operational Costs: Geothermal energy systems have lower operating and maintenance costs than some other conventional heating systems, enabling colleges to recoup the cost of installation. Scaling: Geothermal technology may also be scaled to work in individual buildings or whole campuses. Educational Tools: Energy dashboards have proliferated to help students and faculty monitor the performance of geothermal installations.
In composite climatic zone like Nagpur, Maharashtra, India several electro-mechanical cooling appliances viz. Application of geothermal cooling system is a very apt option for saving energy and reducing emission when compared to conventional cooling techniques. In the present work design methodology of geothermal cooling system is broadly elaborated and is applied to a case study of an educational building located in composite climate. The application of conventional and geothermal cooling systems is compared in terms of energy consumption. This approach can further be extended for larger applications that will reduce consumption of energy and water in buildings. In tropical climatic area like India cooling load inside the buildings is a major concern. In order to reduce the energy consumption required for cooling application, green energy technologies should be adopted and practiced.
Relative to air-source heat pumps, In summer, the geothermal heat pump extracts Water source heat pump systems generally require smaller mechanical rooms than other HVAC systems. Geothermal system Geothermal Systems. Geothermal Heating and Cooling is a complete
A heat pump is a device used to warm and sometimes also cool buildings by transferring thermal energy from a cooler space to a warmer space using the refrigeration cycle , being the opposite direction in which heat transfer would take place without the application of external power. Common device types include air source heat pumps , ground source heat pumps , water source heat pumps and exhaust air heat pumps. Heat pumps are also often used in district heating systems. The higher the number, the more efficient a heat pump is and the less energy it consumes. When used for space heating these devices are typical much more energy efficient than simple electrical resistance heaters. There are millions of domestic installations using air source heat pumps.
I have been passionate about geothermal air-conditioning for 20 years because it is renewable, sustainable, and comfortable. And now with new federal incentives in the United States, I am glad to say that I can add a fourth watchword: doable. Even so, my favorite word of the four is sustainable. You see, I grew up as the oldest of nine children on a nine-acre ranch in the high desert of California. We had a shared party line for the phone and no cable TV. We could get one or two network affiliates by antenna if the atmospheric conditions were right.
