Although it is much less expensive to initially get hooked into the local electric company’s grid than it is to set up and hook into wind turbines, in the long run one saves money by utilizing the wind for one’s energy needs while also becoming more independent. Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling.
Electric bills and fuel bills are rising steadily but the cost of wind turbine energy is zero, and the cost of installing and hooking up a turbine is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient.
In addition, people are moving away from the traditional electric grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to go primitive, political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment.
Again, this motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers.
In nearly thirty states at the time of this writing, homeowners who remain on the grid but who still choose to use wind energy (or other alternative forms) are eligible for rebates or tax breaks from the state governments that end up paying for as much as 50% of their total green energy systems costs.
In addition, there are 35 states at the time of this writing where these homeowners are allowed to sell their excess energy back to the power company under what are called net metering laws. The rates that they are being paid by the local power companies for this energy are standard retail rates in other words, the homeowners are actually profiting from their own energy production.
Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, A lot of this is handled regionally by state law. There wouldn’t really be a role for the federal government, the Energy Department’s Craig Stevens says.
And as might be imagined, there are power companies who feel that it’s unfair that they should have to pay retail rates to private individuals. We should [only have to] pay you the wholesale rate for … your electricity, according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy.
However, the companies seem to be more worried about losing short term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms. Head of the Center for Energy Efficiency and Renewable Technologies of California V. John White points out, It’s quality power that strengthens the grid.

Government Grants for Alternative Energy
In his State of the Union Address for 2007, President George W. Bush called for a 22% increase in federal grants for research and development of alternative energy. However, in a speech he gave soon after, he said to those assembled, I recognize that there has been some interesting mixed signals when it comes to funding.
Where the mixed signals were coming from concerned the fact that at the same time the President was calling on more government backing for research and development, the NREL, the National Renewable Energy Laboratory of Golden, Colardo was laying off workers and contractors left and right.
Apparently, the Laboratory got the hint, because soon after the State of the Union Address, everyone was re-hired. The second speech of the President’s was actually given at the NREL. There is almost unanimous public support for the federal backing through research grants, tax breaks, and other financial incentives of research and development of alternative energy sources.
The NREL is the nation’s leading component of the National Bioenergy Center, a virtual center that has no central bricks and mortar office. The NREL’s raison d’etre is the advancing of the US Department of Energy’s and the United States’ alternative energy objectives.
The laboratory’s field researchers and staff scientists, in the words of Laboratory Director Dan Arvizu, support critical market objectives to accelerate research from scientific innovations to market-viable solutions. At the core of this strategic direction are NREL’s research and technology development areas.
These areas span from understanding renewable resources for energy, to the conversion of these resources to renewable electricity and fuels, and ultimately to the use of renewable electricity and fuels in homes, commercial buildings, and vehicles. The federally-backed Laboratory directly helps along the United States’ objectives for discovering renewable alternative fuels for powering our economy and our lifestyles.
The NREL is set up to have several areas of expertise in energy research and development. It spearheads research and development efforts into renewable sources of electricity; these would include such things as solar power, wind power, biomass power, and geothermal power.
It also spearheads research and development of renewable fuels for powering our vehicles such as biomass and biodiesel fuels and hydrogen fuel cells. Then, it seeks to develop plans for integrated system enginnering; this includes bringing alternative energy into play within buildings, electrical grids and delivery systems, and transportation infrastructures.
The Laboratory is also set up for strategic development and analysis of alternative energy objectives through the forces of economics, market analysis and planning, and alternative energy investment portfolios structurings.
The NREL is additionally equipped with a Technology Transfer Office. This Office supports laboratory scientists and engineers in the practical application of and ability to make a living from their expertise and the technologies they develop.
NREL’s research and development staff and its facilities are recognized for their remarkable prowess by private industry, which is reflected in the hundreds of collaborative projects and licensed technologies that the Laboratory now has with both public and private partners.

Everything You Need To Know About Green Energy
Green energy refers to the use of power that is not only more efficient than fossil fuel but that is friendly to the environment as well. Green energy is generally defined as energy sources that dont pollute and are renewable.
There are several categories of green energy (GE). They are anaerobic digestion, wind power, geothermal power, hydropower on a small scale, biomass power, solar power and wave power. Waste incineration can even be a source of green energy.
Nuclear power plants claim that they produce green energy as well, though this source is fraught with controversy, as we all know. While nuclear energy may be sustainable, may be considered renewable and does not pollute the atmosphere while it is producing energy, its waste does pollute the biosphere as it is released.
The transport, mining and phases before and after production of nuclear energy does produce and release carbon dioxide and similar destructive greenhouse gases. When we read of green energy, therefore, we rarely see nuclear power included.
Those who support nuclear energy say that nuclear waste is not, in fact, released into our earths biosphere during its normal production cycle. They stress as well that the carbon dioxide that nuclear energy production releases is comparable, in terms of each kilowatt hour of electricity, to such sources of GE as wind power.
As an example of the GE production the average wind turbine, such as the one in Reading England, can produce enough energy daily to be the only energy source for 1000 households.
Many countries now offer household and commercial consumers to opt for total use of green energy. They do this one of two ways. Consumers can buy their electricity from a company that only uses renewable green energy technology, or they can buy from their general supplies such as the local utility company who then buys from GE resources only as much of a supply as consumers pay for.
The latter is generally a more cost – efficient way of supplying a home or office with GE, as the supplier can reap the economic benefits of a mass purchase. Green energy generally costs more per kilowatt hour than standard fossil fuel energy.
Consumers can also purchase green energy certificates, which are alternately referred to as green tags or green certificates. These are available in both Europe and the United States, and are the most convenient method for the average consumer to support green energy. More than 35 million European households and one million American households now buy these GE certificates.
While GE is a great step in the direction of keeping our environment healthy and our air as pollutant free as possible, it must be noted that no matter what the energy, it will negatively impact the environment to some extent.
Every energy source, green or otherwise, requires energy. The production of this energy will create pollution during its manufacture. Green energys impact is minimal, however.

An Overview Of Energy Efficiency
While we often think of energy efficiency as the way to save our environment, we also often consider it a costly endeavor. Did you realize, however, that your homes energy bill might be reduced by up to 30 percent through energy-efficiency that includes the purchase or energy efficient appliances and other products? In other words, you can save yourself money while you do your part to save the planet.
Every time you buy a new air conditioning unit, a new washer or dryer, a new refrigerator, microwave, or piece of office equipment, you are affecting the environment, either positively or negatively depending on your choices. Smart choices of products designed for energy efficiency help the air we all breathe and reduce your energy bill each month.
Here is some basic information about how energy efficiency works and why its helpful. A great deal of the energy you consume in your home is produced by local power plants that must burn fossil fuel to create the energy. These fossil fuels might be natural gas, coal or oil.
These fossil fuels also create pollution. This pollution harms not only the environment but ultimately the people, as it causes smog, acid rain and respiratory diseases. Fossil fuel pollution is also a strong factor in changing the climate of the globe.
While we hear a lot about the harmful gas emissions that emanate from vehicles, what we dont hear much about is the fact that your home probably produces twice as much of these emissions as the average automobile.
Opting for energy efficiency through your choice of products that are energy efficient is one of the best ways you can reduce your consumption of energy and thus your distribution of harmful emissions of greenhouse gas. Any household that buys equipment designed for energy efficiency puts a big dent in harmful emissions of carbon dioxide.
In fact, over the lifetime of one of these energy efficient appliances or other products you will have reduced pollution the equivalent of what would be saved by one fewer vehicle for seven years. The use of energy efficient household products reduces nitrogen oxides too, which contribute extensively to acid rain and smog.
The average U.S. household spends about 1500 each year on energy. Energy-efficiency can reduce this bill by 400-450 annually. If youre concerned about energy efficiency and wish to not only save the environment but save yourself some money it will help to know which appliances account for what portion of your energy use and bill.
The biggest, which probably comes as no surprise, is your heat and air conditioning. This is a whopping 45 percent of your energy bill. Your water heater uses up 11 percent of your energy, and your washer and dryer 10 percent. The lighting for your home is seven percent of your energy costs, while your refrigerator is six percent of your bill.
Your dishwasher, computer, monitor, TV, VCR, DVD player and similar equipment each use up about two percent of your total energy consumption. Stoves, microwaves and other smaller appliances generally account for the rest, though at less than two percent of the total each.

Geothermal Comfort, Investing in Savings
According to the U.S. Environmental Protection Agency (EPA) geothermal systems are,“the most energy- efficient, environmentally clean, and cost-effective space conditioning systems available today.” Extremely high levels of efficiency are possible because a geothermal heat pump only uses electricity to move heat, not produce it. A geothermal unit typically supplies four to five kilowatts of heat for every kilowatt of electricity used. Three to four of these kilowatts of heat come directly from the earth itself, and are clean, free and renewable.
Geothermal heat pumps also take advantage of the mild ground temperature for extremely high efficiency cooling. Most systems also include a hot water generator, which diverts a portion of the supplied heat to the domestic water heater. This provides a substantial portion of a family’s hot water needs at a very low cost. Overall, geothermal technology offers the highest cooling and heating efficiencies of any system available today.
Geothermal systems transfer heat from your home to the earth in the cooling mode, or from the earth to your home in the heating mode. Water is used as the heat transfer medium through a closed loop piping system buried in the ground. By using this stable thermal source, geothermal heat pumps provide energy efficient comfort year around with a factory- tested and sealed packaged unit, without the need for a noisy outdoor fan, or a flue.
The environmental advantages of geothermal systems have caught the eye of governmental agencies such as the Environmental Protection Agency (EPA) and the Department of Energy (DOE). Because geothermal technology is lowest in CO2 emissions, it provides a solution to global warming by primarily using the natural energy of the earth. EarthPure® (R-410A) zero ozone depletion refrigerant is available for ClimateMaster geothermal heat pumps for an even friendlier system.
In January 2006 the U.S. Federal government changed the minimum efficiency for air conditioners to 13 SEER from the previous minimum requirement of 10 SEER. Geothermal systems are up to twice the minimum required efficiency! As efficiency ratings increase, operating costs decrease. However, efficiency ratings alone do not tell the “whole story” when it comes to operating costs for homeowners. Fuel type, home construction, geographic location and thermostat settings are just some of the factors.
Over the years, geothermal systems have always been the leader in low operating costs. Recently, however, fossil fuels (natural gas, fuel oil and propane) have begun increasing at a much higher rate than electricity. The U.S. Department of Energy predicts that electricity prices will remain stable over the next twenty years, allowing some increase for inflation. Now is the time to consider electric technologies like geothermal heat pumps for heating, cooling and hot water needs.
Even a high efficiency natural gas furnace with a high efficiency air conditioner is still nearly twice the operating costs as a geothermal system. Since these comparisons are for new equipment (i.e. standard efficiencies = 13 SEER efficiency for air conditioners and 80% AFUE efficiency for furnaces), comparisons to existing equipment being replaced by a geothermal system would be even more dramatic. If the existing air conditioner is older, it may have an efficiency of between 8 and 10 SEER. Older furnaces could be as low as 65-70% efficient.

How is a geothermal heat pump like a refrigerator?
Like a refrigerator, a geothermal heat pump simply transfers heat from one place to another. When a refrigerator is operating, heat is being carried away from the inside food storage area to the outside, your kitchen. Therefore, cooling is not being added to the inside; heat is being taken out.
To understand the operation of a geothermal heat pump, it helps to understand how a refrigerator works. A refrigerator uses a refrigeration circuit with four main components, a compressor (1), a condenser (2), an expansion device (3), and an evaporator (4). Refrigerant (sometimes referred to by the brand name Freon) is pumped through the circuit to transfer heat from the inside of the refrigerator to the outside.
The compressor (1) is the pump. It also pressurizes the refrigerant gas. Since temperature and pressure are directly related, as the pressure increases, the temperature increases. The high temperature/high pressure gas flows from the compressor to the condenser (2).The cooler air in the kitchen (relative to the temperature of the refrigerant, 150 to 180°F [65 to 85°C]) causes the refrigerant to condense into a liquid. When two surfaces at different temperatures touch (or are very near – separated only by tubing), the hotter surface cools and the cooler surface warms. This is a law of physics called the second law of thermodynamics. The condenser therefore releases heat to the kitchen.
The next step in the process involves the expansion device (3).The expansion device is a small orifice that the refrigerant is forced through. The small hole creates a pressure differential between the two sides of the device. Think of an expansion device like a dam on a river with a hole in the dam. The water leaking through the hole is at a low pressure on the downstream side; the water on the other side (being held back by the dam) is at a high pressure. Once again, the pressure/temperature relationship (lower pressure/ lower temperature) creates a cold, low pressure liquid refrigerant that gets fed to the evaporator (4).
As warm air inside the refrigerator (relative to the very cold temperature of the refrigerant) passes through the evaporator coil (4), the hotter surface (air inside the refrigerator) gets cooler and the cooler surface (refrigerant in the evaporator (4) tubing) gets warmer. The liquid refrigerant evaporates back into gas form, and the cycle starts over again as the refrigerant enters the compressor (1). The evaporator therefore absorbs heat from the inside of the refrigerator, which keeps the food cold.
An air conditioner or refrigerator transfers heat in only one direction. A heat pump can transfer heat in two directions, thereby heating or cooling the space. Most heat pumps heat or cool the air. Some heat pumps heat or chill water. An additional component, a reversing valve, is added to a heat pump, which allows the refrigerant to change direction, allowing the space that was being cooled to be heated.
A geothermal heat pump has a compressor, a condenser, an expansion device, and an evaporator like a refrigerator, but also includes a reversing valve to allow both heating and cooling. The big difference between a refrigerator or traditional air conditioner and a geothermal heat pump is the way heat is transferred. A geothermal heat pump transfers heat between the refrigerant circuit and the ground instead of between the refrigerant circuit and the air. The ground is a much milder heat source, since the temperature changes very little over the course of the year. The outside air temperature, however, varies significantly over the year, making a geothermal heat pump much more energy efficient than a traditional air conditioner or heat pump. A geothermal heat pump compressor also operates at lower pressures because of the milder heat source/heat sink (the ground), helping provide longer life expectancies.
A geothermal heat pump is a like a refrigerator in many ways. Simple refrigerator technology coupled with the stable temperature of the Earth provides quiet, reliable, and energy efficient heating and cooling systems for today’s discerning homeowners.

What to do when the Room Air Conditioner Doesn't Turn On ?
On a sunny hot day you are back from home and you switch ON your room air conditioner to get cooled and you find either the air conditioner doesn’t turn on or it doesn’t cool. I am not sure about you but I will certainly get mad in this situation.
Let us now discuss troubleshooting some of these most common room air conditioner problems and solution:
Room air conditioners consume a lot of electrical power. This can lead to less than optimum performance or even complete failure of the system. If your room air conditioner doesn’t turn on:
1.) Be sure the unit is plugged in and turned on properly.
2.) Check if the outlet of the AC is working by unplugging the air conditioner and plugging in a light that works (NOTE: do not plug a light into a 220/240-volt receptacle).
3.) If the light doesn’t go on, the circuit has probably overloaded. You need to check the electric panel or fuse box and reset the breaker or replace the fuse if required.
4.) If the light works, it’s likely that the air conditioner’s switch is faulty or the thermostat needs some adjustment or needs some repairing.
5.) Be sure the thermostat is set to “cool” and is below room temperature.
6.) Always refer to the manufacturer’s instructions (repair and care manual) for thermostat repair. If adjusting or repairing the thermostat doesn’t solve the problem then unplug the unit and call an air conditioner technician. If your air conditioner is under warranty, call the customer care of the company.

What to do when Room Air Conditioner Doesn't Cool
If your room air conditioner that doesn’t cool then you may need to clean it or recharge it with refrigerant. You can clean an air conditioner yourself by disassembling the unit yourself or you can call a professional. But before doing the job yourself you need to read the system manual and make sure you have the right
skills and tools to do the job. Here is what you may need to do:
1.) Unplug the unit and remove it very carefully from the window or the wall and place it somewhere outdoors where you can work on it.
2.) Remove the grille and filter and unscrew the metal case while making sure that you do not damage the coil’s fins.
3.) Wash out the filter or replace it with a new filter.
4.) Clean the inside coil’s fins by using a vacuum with a soft brush attachment.
5.) From the fan side, spray water back through the fins. You will have to protect the wiring and motor with plastic.
6.) Clean the unit up with a rag and allow the system to dry completely.
7.) You can also lubricate the motor as per the “Repair and Care” manual’s instructions.
8.) Then reassemble and reinstall the unit.
If that does not do the work then clean the evaporator and condenser coils. If it still doesn’t works then you may have to call some professional or call the company’s customer care.

5 tips to help maintain your AC
Replacing your air conditioning filter regularly will not only improve the efficiency of your air conditioner but may even prolong its life. When you do not replace your air conditioning filter, dirt, dust and grime block the flow of air, forcing it to bypass the filter and carry dirt directly into the evaporator coil.
Because the coil is the part of your air conditioner that absorbs heat, you want to keep the coil clean to keep it functioning smoothly and to prevent your compressor and fans from failing. Fortunately, replacing your air conditioning filter is not as
intimidating as it sounds if you follow these tips below:
1. Location. Your air conditioning filter will be located somewhere along the duct that returns air from the house and to the air conditioner. Filters are often located in the air conditioner itself or in ceilings, walls or furnaces.
2. System. Different air conditioning filters use different filtration methods to clean the air. Two of the less expensive types of filters use either a fine coating around strands of fiberglass or numerous folded paper pleats to filter the air. There are also reusable filters that use an electrostatic charge to filter the air (these filters need to be cleaned rather than replaced). Although filters that use an electrostatic charge are more costly to start with, over the long term they may end up saving you money, and of course, they are more environmentally friendly as well. To determine which system you have, remove the filter and look at it (it's usually pretty easy to distinguish the differences). If you cannot identify the filter by sight, you can always bring it with you to the store.
3. Frequency. If you do have a disposable rather than a reusable air conditioning filter, check your air conditioning filter every month. Chances are that you will end up replacing it every month to two months during the summer season. You may need to replace your filter more frequently if you have pets or a smoker in the house, if your house is particularly dusty (say if you live next to a dirt road or are in the midst of a remodeling project) or if your air conditioner receives frequent use.
4. Size. When purchasing the replacement filter, be sure to measure the existing filter first. My favorite trick is to keep the box so that I can be sure I am buying the correct filter, but in lieu of the actual box, use a tape measure instead and measure the filter to the closest eighth of an inch so that you can be sure you are buying the correct filter for your air conditioning system. There is nothing more frustrating than coming home with a new filter that is an eighth of an inch too big or too small.
5. Efficiency. Don't be fooled into thinking that replacing your filters less frequently can save you money. Though air conditioning filters are not inexpensive, the efficiency of your air conditioner is greatly increased when the filters are clean. No matter what type of filter you use, make a note to yourself to check it often and to replace it when it starts looking fuzzy.
Because the coil is the part of your air conditioner that absorbs heat, you want to keep the coil clean to keep it functioning smoothly and to prevent your compressor and fans from failing. Fortunately, replacing your air conditioning filter is not as
intimidating as it sounds if you follow these tips below:
1. Location. Your air conditioning filter will be located somewhere along the duct that returns air from the house and to the air conditioner. Filters are often located in the air conditioner itself or in ceilings, walls or furnaces.
2. System. Different air conditioning filters use different filtration methods to clean the air. Two of the less expensive types of filters use either a fine coating around strands of fiberglass or numerous folded paper pleats to filter the air. There are also reusable filters that use an electrostatic charge to filter the air (these filters need to be cleaned rather than replaced). Although filters that use an electrostatic charge are more costly to start with, over the long term they may end up saving you money, and of course, they are more environmentally friendly as well. To determine which system you have, remove the filter and look at it (it's usually pretty easy to distinguish the differences). If you cannot identify the filter by sight, you can always bring it with you to the store.
3. Frequency. If you do have a disposable rather than a reusable air conditioning filter, check your air conditioning filter every month. Chances are that you will end up replacing it every month to two months during the summer season. You may need to replace your filter more frequently if you have pets or a smoker in the house, if your house is particularly dusty (say if you live next to a dirt road or are in the midst of a remodeling project) or if your air conditioner receives frequent use.

5 easy green tips for kids
1. Turn off the lights when leaving a room, or better yet-reduce the need for electricity by opening those curtains and letting the light come in!. Light bulbs require electricity, and often electricity is produced from power plants that use fossil fuels. This is an easy way to save energy, and everyone can help.
2. Recycle. It is easier now more than ever to recycle, and nearly everything can be reused paper to glass. Utilize existing bins, or create your own and have a little fun learning to sort through the different types of products we use on a daily basis.
3. Only use as much water as you need. Turn off faucets when not directly in use, and keep an eye (or ear!) out for dripping or leaky fixtures. Water is another resource, and conserving it is another way to "go green!"
4. Use shopping bags when going to the grocery store. Have fun decorating cloth bags, and then remember to take them with you on your next outing. Reducing the need for plastic bags is a great way to conserve.
5. Make a compost. Composting is a great way to reduce waste in landfills and a wonderful way to naturally fertilize your garden!

Nature's very own pest control - bats!
An easy, low-cost project that you can do to help control the mosquito and beetle population in your neighborhood is to build a bat box!
Bats have dwelled in the mists of legend and folklore for generations, and is it only recently that the myths surrounding these misunderstood little mammals have been refuted.
There are over 1000 species of bats worldwide, and they make up nearly one quarter of all living mammals on the planet!
Every state with the exception of Hawaii has bats, and the majority of bats in the United States are insect eaters-which is where the bat box comes into play. Bats eat several times their own weight in insects every single night, and they are increasingly being encouraged to "move in" by communities and industries as a natural form of pest control.
Depending upon how large your bat box is, it may be able to hold up to 200 of these beneficial little mammals-with each bat eating hundreds of insects each and every night.
Bat boxes are slim, wooden structures with an opening at the bottom for the bats to enter and leave through. Also, a good bat box contains several roosting chambers (the best designs include three or more chambers), and each chamber is at least 20" tall, 14" wide and 3/4" deep.
Placement of the bat box is imperative to ensure that not only will the box attract bats, but that it will maintain whatever size colony that decides to occupy your artificial habitat. In general, most bats prefer very warm temperatures during the day, and the box should be placed in an area where it can receive the most sunlight. Also, the box should be placed high enough that predators will be unable to access the colony.
There are numerous examples and templates for bat boxes online, and it is a fairly simple matter to do a little research and even determine what species of bat(s!) that might be inhabiting your box.
Building a bat box can be a rewarding experience, both as a learning tool and as a contribution to the environment.
Help control the insect population and provide suitable habitat for one of the planet's most misunderstood animals!

Earth loops can cut your utility bills by Michael Dunn
The first time I heard the term “earth loops,” I figured it was some nutty new breakfast cereal for the granola crowd. ”How about a hearty bowl of Earth Loops? Oh, sure they taste like truck tires, but they’re crunchy and nutritious, and they won’t hurt the ozone layer!” Well, it turns out I was wrong. (Although I still think they’d be good with milk.)
Actually, earth loops are components of geothermal technology, which uses the ground as a heat-exchange medium. Because the ground absorbs energy from the sun and stores it deep beneath the surface, people can tap into that stored energy and use it to heat and cool homes. Here’s how it works: A series of polyethylene pipes filled with ordinary tap water is buried deep underground. (In cold climates, antifreeze may be added to the water.) Using a specially designed heat pump, the water is circulated through the pipes, which form one long, continuous “earth loop.” In the heating mode, the liquid in the pipes is cooler than the ground. In the cooling mode, the soil is cooler than the liquid. Because heat always moves from a warm area to a cooler one, heat is exchanged between them, said Paul Fink, territory manager for WaterFurnace Southeast.
WaterFurnace introduced the first closed-loop system to South Florida in 1990, and since then the company has installed about 400 residential units, Fink said. Last month, for example, the company installed a geothermal system at baseball star Dwight Gooden’s St. Petersburg home. The system works – and is energy efficient – because underground temperatures remain constant within geographical locations, he said. In the Tampa Bay area, for instance, the underground temperature is roughly 74 degrees year-round, compared with 70 degrees in the Panhandle and colder as you go north.
Unfortunately, the up-front costs are expensive – roughly $8,700 for a 3-ton vertical heat-pump system – and that’s one of the reasons builders have shied away from it. “Builders are a little bit scared of it,” said Jay Egg, president of Egg Systems Inc., and Oldsmar company that installs the systems. “But people love it.” Fink put it more bluntly: “If a builder is progressive and concerned about energy and the environment,” he’ll try it. “Unfortunately, most builders don’t fall into that category. How can I put this subtly – they’re cheap as hell.” Palm Harbor builder Mike Connor of Schickedanz Bros. has installed two geothermal systems and said they “seem to work real well. From what we’ve seen, it looks like it offers pretty substantial savings.”
Geothermal systems work best for heating, so they’re more popular in Northern climates, Egg said. But the system can save Floridians $40 a month on air-conditioning bills, and because it recycles warm water, a household’s water-heating costs are virtually eliminated, he said. Geothermal systems recoup their costs in five to seven years, and the specially designed heat pump lasts four to five times longer than traditional heat pumps because it is housed indoors, he said. Egg, incidentally, has introduced a new kind of geothermal system to the Bay area in which the earth loops are shaped like a Slinky. They take up less space than traditional straight-pipe geothermal systems, so they can be installed in just about any yard, he said. Those interested in learning more about earth loops can contact WaterFurnace Southeast at (800) 231-5667 or Egg Systems Inc., at (813) 855-7545.

What is Geothermal and how will I benefit from it?
Transform your life, and the environments:
Geothermal installation
“What is Geothermal and how would I benefit from it?”
A common question easily answered! Essentially, geothermal is a natural and eco friendly way to heat or cool your home. Think of a cool spring water lake coming from the ground at 72 degrees? Is this not what we set are thermostats on a sweat dripping humid summer day?
Geothermal installation uses an underground piping system and works with the earth, naturally heating or cooling your home providing your family with the added benefit of a lower monthly utility bill and a hefty tax break of 30% for the installation cost! Circulating the water underground, heating or cooling depending on the season, the earths’ natural temperature is put to good use.
Furthermore, the systems method of utilizing the natural temperature of the earth to furnace or cool your home will create a safe humidity controlled environment reducing overall buildup of molds and mildew.
The underground, durable system comes with long term warranties and in comparison to standard heating and cooling systems, require far less maintenance and therefore provide the consumer, once again, with more money in the bank.
Geothermal heating and cooling has been an idea for hundreds of years. One of the first uses of this natural energy was seen in 1921 by John D. Grant, creating the first Geothermal plant in history. Consequently the use of cheap fossil fuels was already in motion, creating a competitive edge that could not be matched at that time.
Eighty- eight years later, circumstances have drastically changed not only for the environment but our economic needs as well. With the tough standard of living we demand along with the unforeseeable economic burdened future, geothermal energy holds the torch allowing us to live cleaner, safer, and slightly richer lives.

Tax Credit and Benefits
It's a great time to invest in geothermal heating and cooling technology. The American Recovery and Reinvestment Act of 2009 recently lifted the caps on tax credits to qualified geothermal heat pumps, which was previously set at $2000. Homeowners who install a geothermal ground loop or ground water geothermal heat pump qualify for this one time of up to 30% of the total investment, as long as the pump meets or exceeds EnergyStar requirements and installed after December 31, 2009. Business owners will receive a credit of 10% of the total investment. Units installed in 2008 are subject to a $2,000 cap, but those installed between 2009-2016 have no cap.
This substantial tax credit is just one of the many benefits of using geothermal technology to heat and cool your home. Geothermal systems use 25-50% less electricity than conventional systems. According to the EPA, geothermal pumps reduce energy consumption up to 44% compared to air-source heat pumps, and up to 72% compared to standard air-conditioning. In humid areas, like Florida, geothermal heat pumps improve humidity control by maintaining 50% relative indoor humidity.
But it's not just the tax credit or energy savings that should peek your interest, geothermal heat pumps are also extremely durable and reliable. The underground piping carries warranties of 25-50 years, and the heat pumps are known to last twenty years of longer.
So, if you're looking for a reliable system that will also give you tremendous savings on your energy bill over the long-run, a geothermal heat pump may just be what you're looking for!
________________________________________________________________________
Did you know the earth can heat and cool your home while saving on energy costs over the long term?
Just below the earth's surface, the temperature remains relatively constant throughout the year by absorbing half the sun's energy. Geothermal heat pumps tap into this natural ground source of energy reducing heating costs up to 60%, and cooling costs by 25% in summer months. GHP's have three components: a ground heat pump, a closed pipe system, and the air delivery system. Buried in the ground is the closed loop, which is a continuous loop of polyethylene pipe. It's filled with water or an anti-freeze solution and connected to an indoor heat pump, forming an underground loop. The system circulates water through underground pipes that ultimately carry water through the home’s air transfer unit. In the heating mode, the liquid in the pipes is cooler than the ground. In the cooling mode, the soil is cooler than the liquid.
Geothermal technology has been around for a while, but is gradually becoming more popular. A geothermal system costs about twice as much as a conventional heating and cooling system; however, the energy savings combined with the new tax credit on these systems, most people make their investment back in three to five years. In Florida, that could mean a savings of up to $40 a month on air conditioning bills.
These systems are extremely durable, and when properly installed, this tubing will last fifty years or longer.
