Steorn is pleased to announce that public demonstrations of its controversial Orbo technology will begin today in Dublin and continue for the next six weeks.
Orbo technology, which has been in development for six years, provides free, clean and constant energy at the point of use. It can be engineered to power anything from a phone to a fridge to a car. It is controversial because it is an "over-unity" technology, meaning that it produces more energy than it consumes without the degradation of its constituent parts. This is an apparent violation of the Law of Conservation of Energy, which states that energy can neither be created nor destroyed. The implications, not just for energy production but for society as a whole, are profound.
The public demonstrations - which will include live test and replication sessions - will take place in the Waterways Visitor Centre, Grand Canal Basin, Dublin. They begin today, 15th December 2009 and will run until 31st January 2010 (with a break between December 24th and January 4th, inclusive). The demonstrations will also be streamed live at www.steorn.com/orbo.
"This is a pivotal moment for the company," said Sean McCarthy, Steorn CEO, "and potentially, for us as a species. There exists now an opportunity to change everything. At the end of the six week demonstration period, developers will be able to access our technology and start the process of developing Orbo technology-powered products. The Waterways demonstration is the beginning of the Orbo revolution."
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.

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.

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.

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.

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.

By going vertical, we believe that we can increase still by increasing the surface area and the volume of material to get expose to sunlight. So, we have a system that continually recycles is also dynamic system and a close loop.
So, algae goes down starts under it is take. Gets pick up by pump goes up into the reactors and then gravity it takes control moves it to the reactors they get expose to sunlight go back into and take and the cycles are repeating over and over again.
The problem what surface is that one once the algae’s start growing light only penetrate about an inch in inch in half to the surface. So it blocks life from the rest of then surface.
A two we have a Norma’s mouth of water evaporation so we lose enormous amount of water that we costs they have to replace. And the third is most critical thing to us is that we get contaminates from other algae species that just flow and out the atmosphere landing there and become competitive with the algae that we want to grow.
I know that algae is the fastest organism fastest growing plants on the planet and as the questions the greatest amount of carbon dioxide. But the same time it produces lipids basically vegetables oil and a lot of it.
So, if you look at the single cell of algae on the right species as much as 50% of it is body weight is high grade vegetables oil. So what we are questioning carbon dioxide will also producing these high grade lipids that can be used of a variety purposes.
If I grown on acor of corn and I am looking at from the stand point of producing oil I can grow about 18 galloons of oil per acor per year. So now move up lets go to the next highest or what is the most prevalent is palm. Palm we get 7 to 800 gallons per acor per year algae and go up to 20,000 galloons of oil per acor per year, and that is should not open pounces that is not a close bioreactors system.
We took 110th of that State of New Mexico and converted and algae production we can bit all of the energy to Mans for the entire United States. The beauty of algae’s the fact that we can actually be selective about what carbon chance of coming out of it.
So, for example if you want to make jet fuel we can give you a strange of algae that is going to make it the carbon chase their necessary to manufacture jet fuel much more efficiently than you can any other crap.
If you want to make diesel for a truck we can give you the carbon chase that ideal for that. So, we can tailor the lipids base on the species that algae that will rolling.

In the current situation, the cost of electricity continues to rise and thus, we should now be willing to be inclined towards wind energy and solar energy. By learning to use a magnetic generator, you can be assured of free and a life long generation of electricity.
There are various benefits of a magnetic electrical generator which are as follows:
- Works in all types of weather conditions: Generally the wind and solar energy alternatives rely much on natural phenomena, but in case of a magnetic generator, the device would continue to perform well without depending upon weather conditions.
- Safer to use: Evidently, the user is concerned with safety of power generators, as it should be easy and safe to operate especially in houses.
- Fits in a small space: It is very easy to install an eco-friendly magnetic generator and it can fit even in a small, condensed place. Thus, these generators are ideally suited for houses.
- Minimum maintenance cost: Once these magnetic generators are constructed, they can operate efficiently without any problems for long periods of time. Additionally, one need not have to check them on a regularly basis and extra cost for generator maintenance can be avoided.
- Ability to reduce the power bill: The magnetic electrical generator can reduce an individual's power bill by about fifty percent. Thus, it is one of the best reasons for anybody to own a magnetic electrical generator.
- Ease in construction: Majority of people find it easy to build a magnetic electrical generator by themselves. Before constructing, one needs to abide by and understand the step-by-step guide available on the internet. The whole process of construction would take about few hours, and resources required for construction can be availed from a hardware store.

Just like many other global subjects, the present environmental situation is one of those topics which are SEPs or 'somebody else's problem' - to borrow a phrase from Douglas Adams. Whether the size of the task is so big that we are just not able to understand the full implication, or whether we feel that our little efforts will have such a tiny impact on the global situation that they will be worthless is hard to say.
However, if we all take on board the responsibility for making sure that we no longer waste so much of the planet's resources, then together we can ensure a more positive future for all of us. One way to reduce our carbon footprint is to convert to renewable energy where possible. If we as individuals take the decision to reduce our own carbon footprints then this equates to an impact on a global scale.
A great example of an individual who has started to use renewable energy is that of a farmer, who, rather contrarily, grows tomatoes all the year round in several giant heated greenhouses. Now, on the face of it, there is one individual who is going right against nature and using up a lot of resources for his own personal gain. Not a bit of it!
He has employed some unique lateral thinking and has actually adapted his whole farming technique so that he uses completely sustainable energy. He gets tons of fruit and vegetables which are thrown out by the local supermarkets and ferments them in giant slushy containers. A high-technology plant is used to trap the resulting methane which is burned to provide the extra heat needed to heat his greenhouses.
"But what about all that carbon dioxide?" I hear you techno-savvy readers cry. "Isnt that one of the main culprits of global warming?" Well, it is true, that burning methane (CH4), does produce a lot of CO2. He uses this extra carbon dioxide by-product to help his tomatoes to grow. He pumps it into the greenhouses to help them photosynthesize. The growing plants turn it back into oxygen.
This is just one example of someone who has given a few moment's thought and turned a huge scary problem into a neat solution. Just think of the alternative. Year-round heating of huge glass-framed structures; buying imported CO2 -it makes you shudder to even think about it!
We are all searching for ways to lessen our impact on the environment and do our bit for the planet. The best ways to achieve this are by taking small steps and doing things that are achievable and realistic.

"Free Energy — The Race to Zero Point" is an eye-opening account of free energy technology — why we don't have it yet, and what is being done about that."
We already know that the use of electricity, gas and coal are all resources that we may eventually run out of. These are the non-renewable resources that we rely heavily on today. We use these non-renewable resources to do many things, including supplying us with power, heating our homes, businesses and schools and more. When we use all the non-renewable resources up and there are no more to gather, then what? How will we go without the convenience that we are so accustomed to? It's nice to flip a switch to get power and it is even better when the latest technology allows us to press a button to do all the things that women and men had to work for hours to accomplish. We are fortunate to live in a world with so many modern gadgets. Unfortunately when we lose it we may be so accustomed to the modern perks that we will not know what to do when we don't have them any longer.
What we have to rely on in the future is renewable resources. These resources are all resources that offer us an abundant supply and will never run out. They recharge and allow us to enjoy them again and again. The renewable resources consist of Solar, Wind, Biomass, Hydrogen, Geothermal, Ocean, and Hydropower We need all of these and right now we have access to each one of them. What do they do and how do they help us with solar power? Let's find out.
Solar refers to the solar energy that we get everyday either directly or indirectly from the sun. Solar energy can be used for several things, such as heating, electricity to home, schools, businesses, or buildings, heating water, cooling and ventilation.
Wind helps the suns heat down to earth. When the wind combines with the heat of the sun, it causes evaporation. When the water turns into precipitation it produces energy that can then be captured by hydropower.
Hydropower takes energy from flowing water and captures it turning it into electricity. Hydropower is very complicated and requires a great deal of technology in order to successfully accumulate energy from water.
Biomass is an organic matter that can help to make up the plants. It can be used for the production of electricity, transport fuels or chemicals.
Hydrogen is the most abundant element found on earth, usually with other elements. If hydrogen is found alone it can be burned or converted into electricity.
Geothermal looks toward the inner parts of the earth for heat and can be used for power, heating, and cooling.
Ocean produces thermal energy using the heat from the sun. It can also use mechanical energy for the tides and waves.
As you can see the renewable resources are all around us. We know what they do and how we can use them. There are so many benefits to using renewable resources. If we don't use them now we may not have a choice later. The knowledge we learn from today will help us use the energy more wisely.

Free Energy For Life? Really?
I understand you may be skeptical of such a thing, and that it is too good to be true, but this is a reality. So how could you utilise the energy from a magnet? A magnet is something that has energy, yet doesn't require energy input. When you try to connect the same polls of a magnet together, you'll feel the force repelling them. This is natural and does not need an energy input to instigate this. Therefore, a magnetic energy generator takes advantage of these properties.
Did you know that you could completely eliminate your power bill, by constructing a zero point magnetic power generator?
A Zero point magnetic power generator is basically a Free Energy Generator. It uses magnets, and magnetic force to induce perpetual motion. It runs by itself indefinitely without stopping, thus creating completely free electrical energy, which can fully power your home for free. A perpetual motion device refers to a machine that runs perpetually i.e. indefinitely, and produces a larger amount of energy than it consumes. Thus, it produces free energy indefinitely and runs by itself without having to need a third-party device or resource to power it. The free energy devices have been suppressed by the corporate world because such devices would allow people to create their own energy for free, which would ultimately shut down the big energy corporations.
What are the Benefits of Magniwork?
By constructing the magniwork power generator you will be able to generate completely free electric energy, i.e. creating energy without needing any source of renewable or non-renewable energy. The generator powers itself and creates energy by itself without requiring solar energy, heat, water, coal or any kind of resource. This generator powers itself and works indefinitely without stopping, creating a large amount of energy. Here are some of the benefits that Magniwork has:
- It works in every home and requires only a small amount of space.
- You can eliminate your power bill by 50% or even completely, depending on how you implement the magniwork generator.
- It works in all conditions and can work in extreme hot or cold without any problem.
- The material needed to build the magniwork generator is cheap and easily accessible anywhere in the world.
- The process has been simplified and the steps are easy to follow, so even a complete novice would be able to follow them.
- Magniwork contains a bonus chapter about the backgrounds and history of Magniwork.
Can this device be used to power a household?
The magniwork free power generator can be efficiently used to power your home with almost zero costs on your side. Furthermore, the generator is eco-friendly and doesn't produce any harmful byproducts. Hundreds of successful magniwork generators have been built around the world, which proves that this technology really works. It is predicted that the technology will rapidly spread, and some industry-insiders even predict that the magniwork free energy generators will be the energy in the future. These experts estimate, that by 2020 energy companies will start implementing this technology in order to create cheaper and more environment friendly energy. Until that time comes, you can use this technology at a very reasonable set-up cost.
Is It Safe?
The magniwork free power generator is safe to use and operate. It doesn't produce any harmful byproducts or gases, and there isn't any hazard concerning the generator itself. Even if you have young children, they may freely walk in the close viccinity of the generator. The magniwork generator is also a very eco-friendly solution because it doesn't pollute the environment. The generator itself isn't flammable or combustible, so it's completely safe.
How Much Can You Save?
The amount you can save by building the magniwork free energy generator can vary. If you decide to build the generator as a supplement to your current electrical installation, i.e. partially power your household with magniwork, you can easily save anywhere in the range of 30-50%. This means that your power bill will reduce by 30-50%. If you decide to implement magniwork on a full-scale, it will independently power your household meaning that you won't have to pay anything to the power company. The magnetic free energy generator will work by itself perpetually and generate 100% free electric energy. This could be the holy grail for people looking to save on their energy bill.
More information about reducing your energy bill by up to 50% is available at the Magnetic Power Generator Free Energy Blogspot.

It is no secret that the sun can be harnessed to provide a source of energy for homes and businesses.
The sun is a powerful star. It supplies us with energy, through a process called nuclear fusion, and sustains life on our planet Earth. Solar energy, or energy from the sun, has existed since prehistoric times when men would magnify the sun's energy in efforts to start fires.
The sun is a valuable resource that radiates enough energy on the United States in one day to meet the nation's needs for one and a half years. Since it is a free, clean and renewable source of energy, it is an energy source that will play a vital role in our future.
Using the sun's energy for our energy source seems like an easy solution to having an energy supply forever. Harnessing the suns energy is where the problem lies. The sun's rays shine all over the world and not in just one spot. Although it takes only 8 minutes for sunlight to travel to the earth, trying to catch the rays over such a wide area can prove to be tricky. Also, the energy in any one given place will vary due to factors, such as, clouds and weather conditions.
The history of using solar energy began in 1890's when solar water heaters were used in the United States. Solar water heating requires a storage collector and a storage tank. Flat plate solar collectors are mounted on rooftops. Pipes carrying water are pumped through these collectors. The tubes are painted black so they will get hot quicker. As the heat is collected the fluid in the tubes get heated. A storage tank holds the hot liquid. This helps with central heating and cutting fuel costs. Solar heaters became popular when natural gas was expensive and burning wood and coals were burdensome. It's popularity diminished with the discovery of an abundance of natural gas and oil deposits. Now they are making a comeback to replace the depleting fossil fuels that had taken its place.
Solar energy can be in the form of heat energy or light energy. The technology of photovoltaic, or PV as it is commonly called, converts the suns energy into electric currents through the use of solar cells. These electric currents can be used instantaneously or stored for later use. The PV cells consist of pieces of silicon under a thin piece of glass. They have both a positive and negative charge. Simple examples of this are the solar powered calculators that are common today. More complex examples are solar panels placed on roofs. This consists of using thin film solar cells as rooftop shingles, roof tiles, and even glazing for skylights. Unfortunately, the cells generate only about one sixth of the sun's energy into electricity. This means bigger arrays are needed and along with this come larger costs.
Solar thermal power plants use the sun to heat fluid, which in turn, is transferred into steam similar to fossil fuel burning plants. The steam is transformed into mechanical energy in a turbine and electrical energy from a generator. The downfall is solar plants cannot produce energy on cloudy days.
It is expected the next few years will see millions of households using solar energy. As research continues and processes improve, using our sun as a renewable energy source will produce efficiency and cost savings. So, let the sun shine in and take full advantage of this warm energy source where you live.
The heat of the Earth makes up what is known as geothermal energy. When dust and gasses from Earth mixed together 4 billion years ago, geothermal energy resulted.
Inside the Earth at its core, some 4, 000 miles deep, the temperature is estimated at about 9,000 degrees Fahrenheit. Geothermal energy has been used throughout history for bathing, relaxing, cooking and heating. It was thought by some to have healing effects and was used to treat eye and skin diseases. The first geothermal generator that produced energy was built in Lardarello, Italy in 1904. The United States followed with their first attempt at geothermal power in 1912 at The Geysers in California. Today it is produced in twenty-one countries around the world.
Geothermal energy is located deep in the ground. The heat at the core of the Earth has an outward flow. As it moves, it is transferred to surrounding rock layers called the mantle. As temperatures and pressure increase, the rock melts and becomes magma. The magma moves toward the surface of the earth carrying the heat with it. If the magma reaches the Earth's surface, it becomes lava. However, most of it stays below the Earth's crust and heats rocks and water that surround it. These temperatures can reach up to 700 degrees Fahrenheit. When the water travels to the Earth's surface, it becomes hot springs or geysers. Mostly it stays trapped in fractured, porous rocks called geothermal reservoirs. This heat near the Earth's surface becomes a form of energy.
Hot water or steam from the reservoir exerts a force that can spin a turbine connected to a generator and produces electricity. The cooled water is then returned to the reservoir in order for it to reheat. Much exploration and testing needs to be done to determine where the geothermal underground waters are. When ideal spots are located, drilling is done to create production wells that bring the water to the Earth's surface for power generation in geothermal power plants.
Although the costs to construct geothermal plants and geothermal wells are high, the cost of producing electricity is lower over time. The fuel is reliable, stable and does not need to be transported. The white smoke you will see over geothermal power plants is not smoke but rather steam. During the process of operations it may, however, bring some hazardous gases from underground.
The United States stands as the biggest producer of geothermal energy. Unfortunately, interest in it is low and it only accounts for about 1% of this country's energy supply. Through research and experience new methods and technologies for accessing geothermal energy will improve. Tapping into the heat under the Earth's surface can produce much more of the nations energy. We are at a point where renewable energy sources must make their way to the forefront of the energy picture. Not only are fossil fuels being depleted, but also they are ruining our air quality. In time, geothermal energy may become an appealing alternative. Competitive pricing and minimal environmental impact could produce a hot future for this renewable energy source.

Biofuels are moving fuels like ethanol and biodiesel is a diesel that is finished from biomass resources. These fuels are generally merged with the petroleum fuels - gasoline and diesel fuel. They can also be used individually as well. Using ethanol or biodiesel facilitates lesser burning than fossil fuel. However, ethanol and biodiesel are unfortunately, more expensive than the fossil fuels. Nevertheless, they are uncontaminated fuels, producing smaller quantity of air pollutants and are safer and greener to the environment.
Ethanol is an alcoholic fuel prepared from the sugars found in grains, such as corn, sorghum, and wheat, along with potato skins, rice, sugarcane, sugar beets, and yard clippings. Biodiesel is prepared from vegetable oils, fats, or greases. Biodiesel fuels can be used in diesel engines not including any changes in them. It is the best ever budding substitute petroleum in countries such as United States. Biodiesel is a renewable source of energy and thus is safe, recyclable, and decreases the release of the majority air toxins. It is no doubt an eco-friendly version of diesel.
It is frequently asserted that biofuels are carbon-neutral as they release CO2 when burnt that was previously present in the atmosphere. There is a considerable CO2 discharge from the refinery and distillery processes required to make biodiesel or bioethanol, as well as for transport, the use of ranch machinery, and manure production. Biodiesel, in particular, is connected to high releases of the powerful and long-term greenhouse gas nitrous oxide, released by microbes when nitrogen fertilizers are applied to soils, and also throughout the manufacture of nitrogen fertilizers.
There are two main types of biofuels for transport:
Bioethanol, which is an alcohol derivative of sugar or starch, for example from sugar beet, cane or from corn, and
Biodiesel, derivative of vegetable oils, for example from rapeseed oil, jatropha, soy or palm oil.
United States is the world’s biggest bioethanol manufacturer, and this books for 99% of their biofuel for road transport. The region is, as of yet, the world’s chief biodiesel creator, and prefer biodiesel than bioethanol. It is discovered that ethanol has preferably less greenhouse gas releases than petrol.
Among the biofuel crops grown in Europe and the US, biodiesel is usually measured to be more energy competent than bioethanol. A few biodiesel crops, such as oilseed rape are developed with huge magnitude of fertilizers, which compensate for a lot of the greenhouse gas reserves.

Approximately ten percent of energy produced in the United States is from hydropower. In this process, water spins in turbines in generators.
Hydropower is one of the renewable energy sources being researched and implemented to replace fossil fuels, which are in the process of depletion. It does not produce carbon dioxide, as coal power stations do, making it a cleaner, as well as, cheaper alternate way to produce electricity. It is also renewable, with the help of rainwater for replenishment.
The impoundment facility is the most common type of hydropower facilities. A dam is built on a large river or lake to store its water in a reservoir. When water is released from the reservoir through tunnels it flows through a turbine. Since the height of the water behind the walls is so great, the released water goes through the turbine with a great force of energy. As the turbine spins, it sets in motion a generator, which in turn produces electricity. The water then travels back into the stream or river below. Networks of transmission lines and facilities carry the electricity from the generator to users in a form they can use. The Hoover Dam is an illustration of the process just described. When it was initially built, it produced enough electricity for the entire city of Las Vegas. As Las Vegas grew, they turned to other energy sources
The pumped storage hydro plant facility is able to store power. It does so by pumping water from a lower reservoir to an upper reservoir during low energy demand periods. When needs increase, the water is released from the upper reservoir back to the lower reservoir for electricity generation.
Hydroelectric plants require a lot of land in order to build a dam and reservoir. This requires a great deal of money, time and construction. There are not many ideal places to put them and most of these have already been taken. The good thing is once constructed; the electricity is free to produce. Due to costs, the tendency will be to put up smaller hydro plants that are more economical.
Hydroelectric plants using dams have a negative effect on the environment. Through the construction of a dam, there is a blockage of the flow from upstream to downstream. This disrupts the migration pattern of fish. Fish can also be killed passing through the turbines. An advantage to hydropower is the ability to control energy release to meet changing demands.
The population is growing and so will its power needs. Fossil fuels are being used up and there will come a time when they will be depleted. We need to turn to renewable energy sources to meet our needs. Natural resources seem to be a natural solution. Hydroelectric plants can meet our power needs without worries of depletion or pollution. It is also the most reliable source available today. Research and development is ongoing to provide a solution to the damage a dam can do. The potential for hydroelectricity is within our grasp and we must find a way to make this work.

It's certainly no secret: the cost of renewable energy production and its implementation can be extremely high. This is the very reason why tax credits are often used to enable renewable energy sources to compete with fossil fuels.
With rising oil and natural gas prices, the war in Iraq and environmental problems centering on global warming and air pollution, our nation is concerned about their energy security and environmental issues. The United States is recognizing the need and power of renewable energy and is supporting its development through federal income tax credits and incentives.
President George Bush signed the Energy Policy Act of 2005 into law on August 8, 2005. It took over four years for Congress to pass after reviewing several different versions. It extended tax credits for wind and biomass energies for two more years and included additional tax credits for solar, geothermal and ocean energy.
Solar tax credits apply to residential and business users. This tax credit would pertain to eligible equipment installed between 1/1/06 and 12/31/08. The equipment installed would include those solar systems that generate electricity, heat and cool or provide hot water to structures. It must also be operational in the first year the credit is taken and the taxpayer must be the original user. The credit is 30% with a $2,000 cap for each unit for residential taxpayers and it is 30% with a no business cap specified for corporate users. After 12/31/08 the corporate tax credit will return to 10%.
The geothermal corporate credit remains at 10% with no maximum stated. This credit does not apply to geothermal heat pumps and is limited to geothermal energy equipment that produces, uses or distributes energy derived from geothermal deposits. A personal tax credit of 10% with a $300 maximum can be taken for geothermal heat pumps.
The federal government also included production tax credits for renewable energies. These credits allow companies to invest in renewable technologies and write the investment off against other investments. This was a major push of support for renewable energy technologies. The credit was extended until December 31, 2008. The credits are 1.9 cents per kWh for wind, geothermal, closed-loop biomass and 1.0 cent per kWh for hydroelectric power, landfill gas, municipal solid waste and open-loop biomass. These pertain to the first ten years of operation
Similar to production tax credits, there were also provisions for renewable energy production incentives (REPI) for state and local governments, as well as, nonprofit electrical cooperatives. The enacted law included new qualifying energy generation facilities for solar, wind, biomass (excluding municipal solid waste combustion) landfill gas and certain types of dry steam geothermal energy. It was extended through fiscal year 2016 and also included ocean and wave energy.
These credits will be applied to any amount that remains after any other state or utility incentives have been taken. There are numerous states that do offer incentives also. Some new state incentives include a California state rebate program for photovoltaics, an Illinois state grant program for wind energy, a New Jersey state rebate program for geothermal heat pumps and a Pennsylvania property tax assessment for wind energy. These are just a few of the many state incentives that exist.
The United States government and the individual states are promoting renewable energy sources as an energy source to be encouraged. With all the incentives available, this may be one of the best times to make your air cleaner with a commitment toward this energy. With everyone's support we can recharge renewable energy's development.

Man's over dependence on fossil fuels has brought about disastrous consequences. Global warming and Climate Change have been directly attributed to the release of green house gases due to the use of coal, oil and gas. Non-renewable energy sources are not effective, and cost far more than they offer in benefits.
Renewable energy sources absolutely sustain life because they do not emit carbon-based warming and harmful substances into the atmosphere. Additionally, it helps the people live an economical life by not paying the monthly bills on home energy consumption anymore.
Do you want to know what are renewable energy sources and how you can use them to produce free electricity to run your home? The truth about global warming is that it is becoming a much more serious problem that is becoming very hard to deal with today. The main renewable energy sources are examined below.
Solar, wind, and water are renewable energy sources that are friendly to the environment. With awareness to the limits of our natural resources, practically everyone is considering renewable energy solutions.
Residential Solar Power
The residential solar power makes a difference to your family and the Earth where you live in. With the residential solar power at home, you will be able to cut-off some financial expenses.
Harnessing solar power may be extraordinarily affordable if the energy system is all homemade. The storage cells can be used to store the power made during daytime and this will be still in the position to run during night or at times of the blackout.
To successfully turn your home into a residential solar power you need to be situated to a place where there is plenty of sunlight. An open space area would be very feasible to generate more solar energy.
Residential Wind Energy
At present, wind energy is used in a few places to generate electricity, and the feasibility of more wide spread application of this use is being studied.
Wind may be used as a renewable energy source. The energy that can be generated out of the wind power generators is limitless. Unlike the typical energy source produced by private companies, wind energy provides a lifetime power that you need.
Bio Fuels
Bio-fuels are also a renewable energy sources. They have been around for a very long time however just lately, people are beginning to take notice. Liquid bio-fuel which is the one used in cars is a natural and renewable domestic fuel that can only be used for diesel engines.
This can be made from vegetable oils mostly soy and corn. In fact diesel engines were originally created to run on vegetable oil! The nice thing about bio-fuels is that they contains no petroleum, and they are nontoxic and biodegradable.
The fact that we have so many different types of renewable energy sources to choose from means we can use them to our benefit. Some people have already proven the use of renewable energy sources to be very effective that's why this energy saving idea has been shared to many users nowadays.
