Pros And Cons Of Geothermal Energy on a Wide Scale

!: Pros And Cons Of Geothermal Energy on a Wide Scale

The intensely high temperatures at the core of the earth originated from vast masses of hot substances collapsing during the formation of the planet. Since then the heat has continued to be emitted due to radioactive decay of atoms making up the earth below. This earth-sized nuclear-reactor will likely continue to produce heat for millions and millions of years still to come, which makes it a renewable resource.

The other aspect of geothermal power is that water is intrinsically involved in the process. Again, due to the water cycle, it is also renewable. This type of renewable energy has also been shown to reduce incidence of acid rain to only 3% of other traditional forms of electricity generation.

A small amount of potential pollutants e. G. Sulfur dioxide, do come up with the steam, but they are returned into well from which they came, or are changed into industrial chemicals. Because no fuel combustion is required for getting this form of energy, it is very clean, boasting a small carbon footprint. It is thus an appealing alternative to methods requiring burning, with associated greenhouse gas emissions to produce electricity.

In comparison to other power stations, like those that are fuel-driven, the technology employed to channel this subterranean steam to turbines, requires less space, with no pipelines needed to supply fuels to power machinery, since the steam comes up on its own. The steam produced by the high temperatures deep down below the surface is also a local product in every country, meaning that there is no need to depend on foreign input for any aspect of it.

Making use of the wealth of energy stored underneath the surface can be problematic. This is because only sites that have hydrothermal wells close to the surface are cost-effective. Thus areas like Hawaii and Alaska and a few others are currently suitable. This means it cannot be exploited on a wide scale.

Companies that are approached to undertake establishing such power generating establishments are reluctant to do so, as typically these areas are synonymous with earthquakes and volcanoes, making capital investment risky. In addition, the pockets of steam that are found by drilling, can be insufficient in quantity and will run out from time to time, requiring repositioning of the pipes to tap into new wells.

The key to being able to introduce geothermal energy usage on a wider geographical scale is limited by the advancements in drilling technology. The reason for this is that the heat and corrosive elements associated with this type of drilling requires special equipment. This equipment is hugely expensive at present.

Green Construction and Heating Systems

Two of the bigger energy uses are cooling and heating. Green heating systems are designed to minimize such energy use during cooler periods.

There are several heating systems used in green homes. One type uses geothermal energy for heat. Geothermal refers to using the natural heat of the earth. Most systems work by running water from under the earth through a series of pipes called a loop. The loop takes the water to a heat exchanger where the heat is removed from the water and used for heating purposes. The most simple is the open loop. Since ground water generally maintains a constant temperature, water is pumped from one well through a heat exchange device, and deposited into a second well, usually at a distance from the first.

A closed loop geothermal system circulates the water through a series of pipes. The pipes are buried in the ground and the water picks up heat and the heat exchanger removes it. There are several arrangements of piping, but the general idea is the same. Although geothermal heat is very inexpensive, a system has to be fairly extensive to provide all of a homes heating requirements, and most systems are intended to supplement other heating sources.

A much better source of heat is sunlight. Solar power systems convert sunlight to heat for use in space heating and domestic water heating. Most solar power systems have a very high initial cost, but a very low operating cost. This low operating cost is often overlooked in the planning stages when more attention is being paid to the initial costs. In order to maximize the advantages of the low operating cost, it is important to make sure that the home is well insulated. In the case of water heating systems, all pipes must be heavily insulated.

Solar water heating systems can be either passive or active. Passive systems use natural convection to move water from the heat source to the heat exchange point. An active system uses pumps and controllers. The water is collected in a tank fitted with solar panels or heat absorbing materials where it is warmed by sunlight. The pumps move it to a heat exchanger where the heat is removed and circulated through the home. In the case of a water heater, the water can be used directly, and it is replaced by cold water from the existing water supply.

Geothermal and Solar heating systems are two examples of green construction types of alternative sources for heat and energy. The advantage is the reducing of the reliance on fossil fuel generated heat or energy. The technology for utilizing these sources of heat is still in its infancy. It is expected that the rise in green construction philosophy will encourage further experimentation in this area.

Because underground temperatures do not change and remain relatively constant year-round, a geothermal system, which consists of an indoor unit and a buried earth loop, capitalizes on these constant temperatures. The winter, fluid circulating through the system's earth loop absorbs stored heat and carries it indoors. The indoor unit compresses the heat to a higher temperature and distributes it ...

Geothermal Heat Pumps Versus Electrical and Dual-Fuel Heat Pumps

!: Geothermal Heat Pumps Versus Electrical and Dual-Fuel Heat Pumps

There are three options for you to choose from when purchasing a heat pump: Geothermal, which uses the heat from a few feet below ground or water; Electrical Air Source, which utilizes the air from the outside, heats it and then pumps it into your home; and Dual Fuel, which utilizes both gas and electricity to heat your home.

Geothermal heat pumps are considered to be some of the most efficient units. This is because they use the natural heat of the earth which is located a few-feet below the surface of the earth. At this level, the ground temperatures are pretty steady and depending on where you are located range between forty five degrees and seventy-five degrees Fahrenheit. The geothermal heat pump takes advantage of this heat by exchanging heat with the earth through a ground heat exchanger. These systems are also able to cool your home and even provide you with hot water if they are equipped to do so. These systems last longer, are quieter and require little maintenance. They are more efficient because they use the ground heat.

There are also dual-source heat pumps that combine both the geothermal heat sources as well as utilize electricity. These have higher efficiency ratings than your air source electrical heat pump units, but are not as efficient as the standard geothermal system. The main advantage of the dual units is that they are cheaper to install and work almost as well as the standard unit. However, on your standard unit it is estimated that the lifespan for the inside components is 25 years while the ground loops may last for fifty years.

There are two other types of heat pumps you can choose from as well, although they are not going to be as efficient as the geothermal unit. These units are still going to work well and save you money in the long run though. Another type of dual-fuel unit is one that uses both electric and gas. These units are good for those locations that experience the occasional drop below freezing and require a more powerful source of fuel. These units switch between electric and gas.

Air source electrical heat pumps use only electricity and come in several sizes. There are units large enough to heat your whole home and there are units small enough to heat just a room. The size of unit you choose will depend on what your heating requirements are. Typically, these units are used only in those locations that experience the occasional drop in temperature, but have a mild winter overall.

Either unit that you choose will assist you in saving on your electricity bills. If you want to go with the "greenest" unit possible, then you will probably want to consider using the geothermal unit. It is estimated that 40,000 of these units are being installed in the United States each year and that the savings in energy bills will pay for the unit in five to ten years and the unit itself could last you a lifetime.
