Geothermal Energy - Green Heating and Cooling Solution

!: Geothermal Energy - Green Heating and Cooling Solution

You may be seeing more companies advertising Geothermal Heating and Cooling systems and be asking yourself what is Geothermal Energy and why should I be interested in it? A Geothermal heating and cooling system is something that has been below the radar for many years due the impact it could have on the fossil fuel industry; but if you're interested in saving money and doing something good for the environment, a Geothermal Heating and Cooling system is worth doing some research on.

What is Geothermal Energy?

Geothermal Energy is energy stored in the ground that we walk on every day. The ground absorbs the sun's energy everyday and stores it only a few feet below the surface. This energy can be extracted using a series of water pipe lines and then used to heat and cool your home all year round. Geothermal energy on large scale operations is very expensive to tap into through drilling and the ideal geographic areas are limited to supply large cities but systems to heat and cool individual homes have become more practical today than ever before. Due to the limitations Geothermal Energy has for large cities, it's extremely green energy benefits have been over shadowed by the usefulness of Wind Turbines and Solar panels but it's not to say your individual home can't get a lifetime of savings by choosing to install a system like this for your home.

Installing a Geothermal Heating and Cooling System

There are several different ways to install a Geothermal Heating and Cooling system, depending on several different factors. The first thing to consider is the amount of property you own and the second depends on if this system will be a retrofit for your home or something you are considering for a new construction. The most popular system installed in homes today is the Loop System. The Loop system consists of a series of trenches tug in your yard approximately six feet deep and 300 feet long. Obviously for a system like this that consists of anywhere between four to six lengths of pipe stretched 300 feet long requires you to own a piece of back yard free of any septic or well systems. Special underground piping is used to ensure the life of your geothermal system and it is connected to a pump system in your home to convert the water temperature to heat your home in the winter and remove the heat from your home in the summer.

Home Renovation Ideas for Geothermal Energy

If your home doesn't have the property required for a Geothermal Looping System, it doesn't mean you can't get all the benefits from all that geothermal energy can offer your home, it just means you need to consider different ways to tap into this green energy source. One other way is using Vertical loops. This can be done to homes with limited property during the construction of your new home. This method consists of drilling vertical holes in the ground ranging from 180 feet to 540 feet deep. Using the same water pumps that a horizontal looping system uses, you will extract the ground's heat in the winter time to heat your home and transfer your home's heat in the summer months back to the ground through water circulated with heat transfer pumps.

Does your home have an adequate water supply nearby in the form of a farm pond or lake that is at least 8 feet deep? A loop system can be submerged in the lake or pond with a single line trenched back to your home and circulated with water pumps to convert that energy into a green energy heating and cooling system.

Country homes that currently use a well system can take advantage with cost savings through geothermal heating and cooling by using an open loop system. This system requires a second well drilled near your current water supply. Water is drawn from your existing well to circulate through a heat transfer pump that converts the water's temperature into useful energy, then re-circulates the water back into the second well so your original well can draw it again to be continuously reused.

Pros and Cons of Geothermal Heating and Cooling

Pros

- The biggest pro of using Geothermal Energy is that it is renewable and as long as the water keeps circulating, the water will continue to draw and transfer energy.

- Geothermal energy reduces acid rain created by the burning of fossil fuels by 97%

- Geothermal energy will eliminate your heating and cooling expenses to only the expense of running a pump to circulate the water.

Cons

- Due to the expense of trenching water lines approximately six feet deep or drilling 500 feet deep with a vertical system, it could be a very high upfront expense of around ,000.

Geothermal Energy can save your home thousands of dollars in energy expenses and have absolutely no harmful effects on our environment in form of fumes and damage caused by the use of traditional fossil fuels and gases

Air Source Heat Pumps - The Facts

!: Air Source Heat Pumps - The Facts

With the new scrappage scheme recently implemented by the British government involving the distribution of £400 vouchers towards the cost of people replacing their older in-efficient boilers with a greener energy alternative it is clear to see that there is a greater shift towards carbon friendly heating methods by everyone.

Air source heating systems are relatively new to the UK but have been adopted throughout Europe, notably France and Switzerland, for several years now. With constant technological advances and innovations heating technologies are becoming more and more adept at working in harsh condition. Some potential consumers may have reservations with regards to a somewhat unfamiliar heating method such as an air source heat pump and its ability to work effectively in colder climates, but as we can see from their implementation in many households in colder climate countries an air source heat pump can work both effectively and efficiently even when temperatures outside are as low as -15c.

These units are fitted discretely to an exterior wall of your house or flat minimising any possible disturbance during installation and the size of unit needed varies dependant upon the level of output required. The air source heat pump units themselves are often considered to be small and un-intrusive by consumers, especially in comparison to alternatives such as storage boilers or oil boilers. With the smallest Ecodan air source heat pump producing 40-45db of noise and being almost silent from a metre away any possible noise disturbance is also very minimal.

Air source heat pumps produce hot water to heat you home at a consistent temperature leaving your home warm throughout the day, unlike conventional heating options which produce heat in bursts which can leave you experiencing periods of warmth and then cold.

As well as freeing up room in your home where a conventional boiler may have previously been fitted and keeping your home at a consistent temperature these heat pumps also allow you to make great savings on your heating bills. Not only will they reduce your heating costs, but any electricity that is used will be used more efficiently. With the Mitsubishi Ecodan air source heat pumps working at between 300% - 500% the amount of electricity used to power the unit is tripled in heat energy.

With an increasing amount of people adopting greener energy solutions whether to heat their home or produce electricity to be used within the home increased government incentives and grants is set to see a further rise in the adoption of green energy alternatives within the UK in 2010.

GeoExchange Systems

!: GeoExchange Systems

Geothermal heating and cooling systems are considered to be the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available today. These systems are so good that the U.S. Environmental Protection Agency (EPA) has said that they are. Geothermal technology uses the earth's renewable energy below the surface, to heat or cool your home or any other building. This system is sometimes referred to as a geothermal heat pump, a ground source heat pump, or green heat. GeoExchange systems are the best choice you can make for your pocketbook and your planet.

In the winter, a water solution circulating through pipes buried in the ground absorbs heat from the earth and carries it into your home. The GeoExchange system inside the home uses a heat pump to concentrate the earth's thermal energy and then to transfer it to air circulated through standard ductwork to fill the interior space with warmth. In the summer , the process is reversed and heat is extracted from the air in the house and transferred through the heat pump to the loop piping. The water solution in the ground loop then carries the excess heat back to the earth. The only external energy needed for geoexchange is the small amount of electricity needed to operate the ground loop pump and fan.

The benefits to using a GeoExchange system is lower utility bills (25% to 70% lower than with conventional systems), lower maintenance, and higher levels of comfort year-round. You will also have the peace of mind of knowing you are being environmentally responsible. Since a Geoexchange system burns no fossil fuel to produce heat, it generates far fewer greenhouse gas emissions than a conventional furnace, and completely eliminates a potential source of poisonous carbon monoxide within the home or building.

The EPA found that, even on a source fuel basis, accounting for all losses in the fuel cycle including electricity generation at power plants, GeoExchange systems are much more efficient than competing fuel technologies. They are an average of 48% more efficient than the best gas furnaces on a source fuel basis, and over 75% more efficient that oil furnaces. In fact today's best GeoExchange systems outperform the best gas technology, gas heat pumps, by an average of 36% in heating mode and 43% in cooling mode.

Homeowners using a GeoExchange system can see a savings of 30% to 70% in the heating mode, and 20% to 50% in the cooling mode compared to conventional systems. A well designed residential system can exhibit positive cash flows from the first month that it is in use.

Today there are more than one million installations in the Unites States. Although this is a very small percentage of the total HVAC market, the number of people who are choosing to install geoexchange systems is growing rapidly (about 20% every year) as more learn about the technology. There are also a large number of commercial enterprises, including factories, retail stores, office building and schools using the GeoExchange systems to save energy and protect the environment. Should all of the nation's schools convert to geoexchange, the EPA has estimated that we could reduce oil imports by 61 million barrels annually.

The prices have a wide range based on a number of variables, such as your home or building's size and design, the brand and model you choose, your location, and other factors, so it is impossible to provide a number, but you may be surprised how affordable it is. To find out how much it would cost to install a GeoExchange system into your home or business, you will need to contact a contractor in your area for an estimate. There are Federal & State incentives offered to install GeoExchange systems in many areas so check to see if you qualify for any rebates.

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

!: 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.
