Harvesting Ground Heat Through Geothermal Heating Technology

Just below our feet lies an energy source that can easily help us warm both our homes and hot water tanks. This energy source is known as thermal energy and can be harvested using specifically designed geothermal heating technology. This article will give you a better idea of how this natural energy source has come into existence and how geothermal heating systems actually harvest this energy.

But how does this energy under the earths surface occur? Thermal energy is caused by a number of contributors. For example, heat radiates out from the earths core and warms the ground. The earth also absorbs energy from the heat of the sun. The strength of this heat energy trapped beneath the surface of the ground will of course depend where you are in the world. It does not really matter where you are in the world though as geothermal heating technologies are able to extract heat from the ground however weak that heat is.

The concept of harvesting heat energy that is present beneath our feet is far from new. In the Roman Empire water heated naturally underground by geothermal energy was put to use to keep their spas hot. In effect this was the start of basic geothermal heating systems. This harvesting of naturally occurring geothermally heated hot water is still used today in some parts of the world. Iceland, for example, makes full use of this naturally occurring energy source using geothermal power plants.

Geothermal heating systems such as the Ground Source heat pump are now used across the world with much success. As the name suggests the Ground Source heat pump collects heat from the beneath the ground and literally pumps this heat around a home or property. Ground source heat pumps use a series of pipes that are laid underneath the surface of the ground. The loop of pipes are filled with a solution has properties to absorb geothermal heat energy directly from the ground. The solution is pumped through the loop of pipes, and gathers heat as it travels. The solution eventually passes through the heat pumps the heat exchanger part of the system where the heat is extracted and refined. This harvested heat is then used to directly warm living spaces and heat hot water tanks.

Geothermal heating systems are forecast to become even more popular with households across the globe. In general many people want to become more environmentally friendly and do their bit to help save the planet. Most people are also becoming increasingly frustrated at the incredibly high prices they are paying for fossil fuels such as gas and coal. Alternative ways to heat homes that are eco-friendly and cheaper to run, such as Ground Source heat pumps and other geothermal heating technology, are the ideal answer.

Would you like to discover more about geothermal heating technology and the benefits of investing in a heat pump system for your home?

Wind Energy Or Solar Energy - Which Is Best For Your Location?

When choosing the best option for reducing your power bill, it is important to understand the benefits and drawbacks of two of the most popular energy sources: Wind Energy and Solar Energy.

Solar Energy

The earth does not produce energy on its own. Solar Energy creates two other sources of energy often utilized by homes and businesses: water and wind. Solar Energy is collected using various types of Solar Panels, which is then channeled into a home via "Grid-Tie" or "Off Grid" systems.

The Grid-tie systems collect solar energy and feed it directly into your electrical system through a grid-tie inverter. In this arrangement, the electric company is essentially the storer of any excess electricity collected throughout any given day. The advantage of this method is the cost savings in needing to purchase a battery bank to store the energy. If you happen to produce more electricity than you use, many electric companies will pay their customers for each extra Kilowatt Hour (KWH) of electricity fed back into their system. However, the amount electric companies pay their customers for the electricity is not typically as high as the amount they would charge you for the same amount.

Off-Grid systems are the same as Grid-tie, except they store the extra solar energy collected by solar panels into batteries. The off-grid inverters cost less, but there will be a substantial battery cost. The amount of batteries needed will depend on the number of solar panels you have. The more solar panels you purchase, the more batteries will be needed to store the energy.

Some areas of the country are more suitable for solar energy than others. Solar Panels need the direct rays of the sun in order to operate at peak efficiency. Cloudy areas such as Seattle, Washington are not going to produce as much solar energy as places like Phoenix, Arizona. While Seattle is one of the worst areas, if you were to make a line that went from Minnesota to Ohio to Maine, that area of the country fares only little better in its worst month. See a Solar Radiation map for more specific information in your area.

Wind Energy

Wind energy has the distinct advantage of being available both night and day. When the storm clouds roll in, blocking the afternoon sun, wind energy is there to pick up the slack. Interestingly, wind energy is actually produced by solar energy, albeit indirectly. As the sun's rays come in contact with the earth, some areas absorb more heat than other areas, and some areas receive more direct rays (e.g. the equator) than others (e.g. the North Pole). The warm atmosphere gases then naturally move to colder areas, creating wind.

Some areas of the country are more suited for wind energy than others. If you live in the southeastern section of the United States, wind energy is not a good option unless you live in a high elevation or near a coastline. A wind resource map can be located on the web site listed in this article.

Another important factor in determining whether or not wind energy is a good possibility for your home is whether or not you are able to place a wind turbine at a high enough elevation to produce a cost-effective amount of energy. Most guides recommend wind turbine installation at an elevation of 30 feet higher than the surrounding area. The higher your wind turbine, the more energy it is going to produce. Of course, this also means that initial installation costs will be higher as well. Overall, wind energy is a great way to reduce your carbon footprint. Just make sure your location is well suited for it.

Conclusion

It can be a very satisfying experience knowing that you are saving money and reducing your carbon footprint every time you see the wind blowing or the sun shining. With the federal government basically picking up 30% of the tab through tax credits, now is a great time to invest.

Various Renewable Energy Resources And The Best To Use At Home

So do you want to know about renewable energy?

I understand why a lot of people are interested in this subject. In fact, I am one of them myself.

Renewable energy is becoming a very important resource of power; even governments are conducting huge researches on this matter.

I want you to think about this for a second- What if all countries and individuals use renewable power, how would it be?

Well, it will definitely change the future of the planet.

Renewable energy

It is the energy generated from natural resources such as sunlight, wind, geothermal heat, and many other resources. These resources are naturally replenished.

Geothermal energy: It is obtained by trapping the heat of the earth itself. It can be done in some places from the surface and in others it has to be a few kilometers deep.

Hydropower: Energy in water can be harnessed and used. Water is about 800 times denser than air, so even a slow flowing stream or a moderate sea swell can yield a considerable amount of energy.

Bio fuel: There are various types of bio fuels that could be made out vegetable oils, animal fats, the sugar components of some plants and many other resources.

Solar energy: It is the energy derived from the sun through the form of solar radiation.

Wind energy: Air flows are used to produce energy.

Warning: These last two renewable energy resources are perfect for everyone to use at home or even at the office. You can easily buy or build your own solar panel and wind turbine, and produce green free energy.

You can go green and start using renewable energy resources!

Cost Effective Alternatives For Energy

Solar energy has been used by man since the beginning of time to cook or dry food, warm dwellings and heat water among others. Today solar energy is used for heating structures, lighting buildings, heating water, solar powered electricity and a few brave souls try to power their vehicles this way.

Biannually there is a solar-powered car challenge, where mostly universities and enterprises compete. This has advanced the technology for solar cars, in 2007 the winner had an average speed of almost 57 miles and hour. Not bad over an almost 1900 mile course. Solar costs are often rebated by governments on a local or federal level to entice people to convert to solar energy. Up to 30% of total installation of solar hot water or solar electrically can be deducted from taxes as credits.

Biomass is made of anything that burns; garbage, paper products, dead trees, yard clippings, saw dust. California alone produces 60 million tons of biomass each year which if converted could run the electricity for two million homes! That's worth thinking about. The biomass is collected and burned in giant furnaces which are used to head water in a boiler the energy from the steam turns generators and turbines. This is a great way to reduce land fill and make energy which is clean and uses unwanted materials.

Wind energy is clean and efficient as long as the wind blows. A 10-kw wind turbine generates enough power to run an average household and a 250-kw turbine can run an elementary school for a year. Clean and efficient but almost always needs a back up plan in the event of a calm. Unfortantely these turbines or "wind mills" are very expensive to purchase.

Water produces electricity by quickly flowing or falling, the water rushes through a power plant and with the use of turbines and generators the energy in the water is used to produce electricity. Clean and efficient with moderate to high amounts of useful energy compared with low operating and maintenance cost. All kinds of clean natural resources are available but with our constant need for more and more energy we have to use explore all available alternatives.

The Advantages Of Using Wind Power

Wind power is the most efficient type of renewable energy and can be a good option for heating and powering our homes. This process converts wind energy into electricity using turbines. Wind has been used for decades to power many things including ships. Windmills were used to pump water and operate mills. While it might seem like a new ides, the use of wind power is not novel as humans have been using it since 17th century BC.

Wind occurs due to the uneven heating of the earth as the north and south poles receive less sun then the equator. Land also will heat faster then water and these different heat pockets cause wind. The greatest amount of wind power is found at high altitudes where it is always windy.

In order to get the best wind power conversion you need to put windmills or wind turbines in good locations. You need to use a spot that has consistent wind, where you are able to easily hook up transmission lines and also consider the natural surrounding land and environmental concerns of putting up the turbine. There is special software available - wind energy software - that can calculate the impact on the area by putting up wind turbines.

Offshore wind farms are very expensive to build but their constant energy production does offset these large costs. For powering entire cities and towns, offshore wind farms are a good option as there are not many suitable spots on land to put up wind farms but in shallow water there is always a wind so you can always produce power. All you need is a light breeze to convert wind energy to electricity.

Wind power has many advantages as it does not pollute, can provide extra income to those that may rent their land to wind farms, has more jobs per gigawatt of electricity then a coal station, is a renewable energy source and is a sustainable energy source.

While you can use wind farms on a large scale, it is also possible for the individual to use small scale wind power as there are many wind turbines designed specifically for the home that can be connected directly to your electrical system. Wind turbines are used in conjunction with batteries for home use and can also replace diesel generators. The most popular type of wind turbine is one that hooks up directly into the electrical grid so any power you do not use is feed back into the electrical company and you receive electricity credits.

There are many incentives available for those interested in using wind power. You will receive a tax break for using renewable energy. Green credits and property tax exemptions are all examples of this. But best of all, wind power allows for keeping the modern conveniences that we have come to love while reducing our consumption of fossils fuels and lessening the adverse impact on the environment.

How To Invest In Green Technology - What To Look For

As the world community has grown more attentive to environmental concerns, such as global warming and climate change, the presence of related investment opportunities has greatly increased, driving robust growth of green investing in 2007, as per a recent Merrill Lynch and Capgemini report.

Whether perceived as an investment opportunity or a responsibility of global citizenship, overall participation in green initiatives has risen rapidly in recent years due to the fundamental need for sustainable development, and, as a result, the undeniable growth potential of the green sector.

Furthermore, it seems the era of economically viable green power has finally arrived, as the impact of soaring oil prices on consumer attitudes and the widespread acceptance of global warming implications converge. Individuals, businesses and governments alike are actively pursuing the integration of green initiatives into everyday systems and investment strategies, adapting to and preparing for what is quickly becoming the way of the future, the report says.

Typical green buildings

Capitalizing on the fundamental strength of demand for green initiatives, the investment community has been particularly invigorated by the attractive financial returns of green investments that have accompanied the already appealing environmental and social benefits generated.

In much greater size and proportion than in recent years, investors have been supporting innovative research and development initiatives in search of alternative fuels, renewable energy and other advanced technologies. Today, investors are presented with many vehicles through which to back green initiatives, such as mutual funds, ETFs and other pooled products or alternative investments.

In 2007, these investment vehicles drove robust growth in green sectors. For example, total investment in the clean technology sector increased to $117 billion in 2007, up 41 per cent from 2005,114 with particular strength in the wind and solar segments. In fact, in the three years ending November 2007, gains in the wind segment exceeded 300 per cent, while solar posted the highest growth in 2007, roughly 150 per cent. Furthermore, the solar segment produced the highest proportion of IPOs of any green sector over the course of last year, including the Merrill Lynch-led $6.5-billion issuance of Iberdrola Renovables, the world’s largest renewable energy company.

Despite being burdened by poor overall market conditions in late 2007 and early 2008, green investing trends have been driven by an underlying commitment to sustainable development, which takes profit incentives into consideration alongside social responsibilities. As a result, the sector will likely weather short-term fluctuations and deliver strong returns in the long run.

Interesting Facts About Solar Energy You Should Be Aware Of Before Buying Solar Power Panels

With the cost of electricity going up, the importance of talking about a renewable energy source is also gaining popularity among people, all over the world. With that said, here are some interesting facts about solar energy.

Solar Power Fact # 1:
The most thought provoking idea about solar energy is how little of the energy creation on the planet, comes from the sun. Only 0.1 percent of power comes from energy through the sun and is converted into electrical current. If there were more people who would install solar cells in their homes and cars, solar energy could cover more than the Earth's power. Everything would be covered, even needs for transportation and housing.

Solar Power Fact # 2:
Another interesting fact about solar energy is how much it's worth and how much money can be saved using it as a source of energy. If your roof is 1000 square feet and you install solar panels, you could potentially save as much as 6,460 dollars a year, over the cost of oil heating. The downside though, is that the initial investment will cost you between $20,000 and $50,000 to install; however there are tax incentives which offset the cost.

Solar Power Fact # 3:
One more of these interesting facts about solar energy, is that China is working with the United States to build entire communities which are created and powered by renewable energy resources. Homes are being constructed out of straw bales and are powered with solar and geothermal heating. Giving the size of China's population, the pollution problem has increased the development of renewable fields. Its hope is for the Chinese people and its country, to become more efficient and less costly.

With these interesting facts about solar energy, we see why it is becoming more and more important.

Resources For Alternative Energy

There are many different forms in which alternative energy is available.

One of these is solar power. Solar power is driven by photovoltaic cells, and these are progressively getting less expensive and more advanced. Solar energy power can be used for electricity, heating, and making hot water. Solar energy produces no pollution, as its input comes completely from the sun's rays.

However, much more work still needs to be done in order for us to economically harness the sun's energy. For the time being, the resource is a little too conditional—storage batteries are needed to be used as backups in the evenings and on inclement days.

Wind energy has become the most-invested-in (by private investors and governments together) alternative energy source for the time being. The great arrays of triple-bladed windmills are being placed all over as “wind farms”, to capture the motion of the wind and use its kinetic energy for conversion to mechanical or electrical energy.

Of course, there is nothing new about the concept of a windmill for harnessing energy. Modern wind turbines are simply are more advanced variations on the old theme. The drawback to wind energy is...what do you do when there is a calm, still day? Needless to say, during these times the electric company kicks in for powering your home or office. Wind energy is not altogether independent.

Hydroelectric energy is available as a source of alternative energy, and it can generate a substantial amount of power. Simply put, hydroelectric energy uses the motion of water—its flow in response to gravity, which means downhill—to turn turbines which then generate electrical energy.

Needless to say, water is ubiquitous; finding sources for driving hydroelectric turbines is, therefore, not much of a problem. However, hydroelectricity as a source of alternative energy can be complicated and expensive to produce. Dams are often built in order to be able to control the flow of the water sufficiently to generate the needed power.

Building a dam to store and control water's potential and kinetic energy takes quite a lot of work, and operating one is complex as well,and conservationists grow concerned that it. Of course, a dam is not always needed if one is not trying to supply the electrical needs of a city or other very densely populated area. There are small run-of-river hydroelectric converters which are good for supplying neighborhoods or an individual office or home.

Probably the most underrated and under-appreciated form of alternative energy is geothermal energy, which is simply the naturally-occurring energy produced by the heating of artesian waters that are just below the earth's crust. This heat is transferred into the water from the earth's inner molten core.

The water is drawn up by various different methods—there are “dry steam” power plants, “flash” power plants, and “binary” power plants for harnessing geothermal energy. The purpose of drawing up the hot water is for the gathering of the steam.

The Geysers, approximately 100 miles north of San Francisco, is probably the best-known of all geothermal power fields; it's an example of a dry steam plant.
