Wind power can be harnessed to produce energy. Wind energy technology can be used to  convert kinetic energy into electricity and thus provide power for homes and even businesses. There are many countries in the world that have embraced wind energy technology to create their daily supply of power. All this is done using wind turbines. At the moment, estimates suggest that 2% of all power used by humans is received from wind sources. There are many reasons why more and more people are going this way. This is a look at some of the dynamics and merits of this resource. There is little doubt that future will involve far more renewable energy resources as more countries develop the infrastructure for the types of systems that can take advantage of such energy. And this includes more production of power from wind.

History Of Wind Power

Man has always intuitively grasped the potential in wind energy technology. There are many examples of ancient civilizations utilizing wind power, one of which has to be the evolution of sail power to drive boats and ships. Many empires were created and maintained by moving manpower and merchandise using sail power.

Another example of mankind’s use of wind energy technology is for irrigation. It is this foundation that has formed the backbone of different technologies that help harness wind energy. Many people will refer to this kind of power as windmill energy. The potential in wind power is great and it has not been fully exploited. However, this trend has been found to be changing as more people recognize the importance and economy of this kind of power.

The greatest merit about wind energy technology is that it causes no pollution to the environment. We are living in times when pollution has become a problem and a vice that threatens the very existence of life. With wind energy technology, there is much to look forward to keeping in mind that pollution will not be there. Many can tap into this power to supplement their income. There are many rural farmers who have rented wind turbines and they can gain considerably. For this reason, governments have been able to use this sector to help empower rural folk so that their lives can be made better.

Wind energy technology has been seen to work better because it is more sustainable. There are many governments that are looking into this kind of energy production because of its sustainable nature. Wind energy technology is also being improved to make the process of harnessing power better and more efficient.

Installing a clean energy system in your home can be a costly exercise. Many people baulk at the prospect of having such a system before they consider all the benefits because of this cost. It pays dividends to know what you are getting into to avoid disappointing results.

For instance, you may have expected a large saving in your power bill with the introduction of a clean energy system but in reality the savings are not very good. The truth is you have to treat renewable energy as a clean energy investment. The returns will not be seen immediately.

Energy Efficiency

Many people make the mistake of thinking that a clean energy system will give you energy efficiency immediately. In truth, the idea of getting a clean energy system should prompt you to think about using energy more efficiently in general. So you should think about ways to save energy in your home before installing a renewable energy system.

To this extent, think about phasing out your incandescent light bulbs. Instead you should be using compact fluorescent lamps. These bulbs use less energy and last longer. Start looking at other things you might need to replace in your home such as household appliances. Look for the modern, energy efficient alternatives for replacement.

Other household appliances such as printers, televisions, cell phone chargers, and radios can consume energy even when turned off. As long as these appliances are plugged into a power source they are leeching electricity and adding to your electricity bill.

To avoid this and make some savings on your electricity bill you should buy power strips to plug your appliances into. Power strips have a switch that you can switch on and off to ensure that your appliances are not using any electricity when not in use.

Older refrigerators, washing machines, and dryers are less energy efficient. You will get more out of your clean energy system when you have appliances that are energy efficient. This applies to air conditioning and heating systems.

Considering The Right Solution

Once you have started to take these small steps toward energy efficiency you can then think about what clean energy system is right for you. Solar power is gaining popularity but it is not the best solution for everyone. Wind turbines are another possible solution for anyone who would like to have a clean energy system in place.

A study of the annual weather patterns will help you to make a better decision as to what clean energy system will be best for you. Consulting with a clean energy expert will also help you to make the best decision for your home.

There are many tax benefits, rebates or even grants to use renewable energy systems in most developed and developing countries. Check out if you qualify for some of these incentives. It could offset most of the initial financial outlay that you have to make. It could even mean getting a clean energy system is a no brainer.

Vertical wind turbines are making an impression in the alternative energy scene these days for their unique design.  Traditional horizontal wind turbines rely heavily upon wide open spaces and strong and constant wind speed of around 10 miles per hour in order to be effective, however vertical wind turbines are the next generation of wind turbine and can go where standard wind turbines cannot.

Designers had to address the issue that most wind turbines operate under, such restrictive and specific conditions which made them unsuitable for use by the general population.  The solution was to create a design that could operate under realistic conditions that would see their use validated by a wider market making the use of vertical wind turbines a realistic replacement for conventional energy sources.

The resulting design was a vertical wind turbine created with the urban user in mind.  No longer were consumers required to live in the middle of farmland or to have vast amounts of space to take advantage of the new vertical wind turbines.

The beauty of the vertical wind turbines design is because of its vertical nature it is able to harness wind even at difficult angles as you would expect to find living under city conditions with the constant wind direction changes characteristic of wind hitting and deflecting against building surfaces and unlike traditional wind turbines, vertical wind turbines do not need to be constantly pointed in the direction of the wind flow in order to be effective.

When researching to see if a vertical wind turbine is for you, something to remember is that there are 3 main models:

1. Savonius Wind Turbine – this particular vertical wind turbines design is simple and cost effective and therefore easy to assemble from a ready made kit, however its speeds can be limiting, restricting its use for smaller scale operations.

2. Darrieus Wind Turbine – this vertical wind turbines design tends to have more moving parts and is more complex to construct.  May require the assistance of a professional for installation and can be more expensive than the Savonius however the Darrieus can achieve higher wind speeds making it a feasible energy source.

3. Helical Wind Turbine – This is the best vertical wind turbine on the market because it can still generate electricity even in low wind conditions.  Installation can be expensive however worth it considering the energy savings over time.

Although Vertical wind turbines require less windy conditions to operate effectively it still pays to live in a location that offers a good amount of wind to ensure a constant supply of energy.

To further explore this avenue and to see if you’re a good candidate for vertical wind turbines, seek the advice of a good Wind Power Evaluator.  They will be able to recommend based upon your location and the amount of wind speed whether or not a vertical wind turbine could solve or fit into your energy needs.

So there you have it, no need to have the traditional, windmill like wind generator theses, why not go for a  vertical wind turbine instead.

With monthly energy bills going up each year it makes sense to look into making your home a green energy house. Why ? Well green energy homes are not only safer for the environment but there is a good chance that they will end up saving you money in the process.  Here are a few tips to make a green energy house and save money on your energy bills too.

First Things First

Green energy houses do not need to have fancy energy saving gadgets. There are a lot of new green energy technologies that you can use together with good old common sense to save energy. One of the simplest and easiest ways to turn your home into a green energy house is to simply make your home more energy efficient. How? First, you need to check your home insulation. Poor insulation can affect the amount of energy that we use at home.

During the winter, we spend more money on heating because our home is leaking heat in so many places. During the summer when the heat is at its peak, we spend so much energy trying to cool our place down. Again, the primary culprit for this excessive use of energy is those leaks. To make your home energy efficient and green, you need to invest in good insulation. There are many incentives to replace old insulation or even install it into your home for the first time. Check out in your region for any incentives and take advantage of them.

Second, replace those incandescent lamps with energy saving fluorescent lamps. Those fluorescent lamps will help you save a lot of money. Moreover, fluorescent lamps last longer than incandescent lamps so you need not worry about throwing these things into the landfill after a few weeks or so. Again, check out for state or national government incentives to get energy saving light bulbs to replace the old incandescents.

Third, turn off the lights, open the drapes and let sunlight into your home during the day. Sunlight can turn your home into a green energy house. You will be able to save a lot of money if you use natural sunlight at home during the day. Moreover, sunlight is a proven natural disinfectant so if you want to keep your home relatively free from germs, you should make use of the disinfectant power of the sun. Try to be more conscious of the electricity that you use. Switch things off at the wall. Switch things off that you are not using period. Get more energy efficient appliances and update old appliances like fridges that are not energy efficient.

Fourth, when it is not so hot outside, shut off the air conditioner and open the windows. Let the breeze into your home. Not only will you be able to save money if you open the windows, you can also help keep your family a lot healthier. Studies show that people who breathe fresh air are naturally healthier than those who rely on the air conditioner most of the time.

Eco houses, short for Ecological houses, are the homes of the future given the concern over the environment and government incentives to build more efficient housing. Not only are they sustainable but they are designed to raise the bar of current living conditions in traditional suburban homes.  Eco houses are created in such a manner that it lessens both environmental and health impact, everything from its design through to the construction phase to the final product, an eco house continues to be sustainable throughout its entire lifetime.

Despite misconceptions, eco homes are evolving to look like better, more energy efficient versions of their traditional counterparts where the only thing really distinguishing an eco friendly house from standard housing are the materials it was constructed from and its increased efficiency.  This is the dream for architects and builders to create future homes with all of the benefits of sustainability without sacrificing modern aesthetics or creature comforts and the hope that one day, all homes will be built with an eco purpose in mind.

Eco houses have their own set of criteria, here are just a few of them:

Fully integrated alternative energy system is what makes eco houses truly sustainable.  They usually have their own array of solar panels, solar shingles, wind generators or geothermal systems that are either partially or completely independent from the main power grid.  These forms of alternative energy allow eco houses to minimize their environmental impact lessening their need for dwindling fossil reserves and their reduction of carbon emission output.

Eco houses also take advantage of sustainable materials including ethically harvested wood from non endangered rainforest land and locally made building materials including bricks that contain less energy content and less of a carbon footprint associated with its creation.  The angle eco houses take is that everything both living and non living has an energy fingerprint tied to its creation or to its energy using activity.  When it comes to construction materials, the aim for eco houses is for this energy fingerprint to be as minute as possible.

Another important energy saving eco house feature are its windows.  Approximately one third of a home’s energy is lost through its windows, any home older than 14 years of age will more than likely have heat leaking inefficient windows, luckily modern day homes built from a sustainable stand point understands that homes with efficient windows will generally decrease an average heating bill by up 25%.  For a window to be energy efficient it should be leak proof and double or triple glazed.

Another feature of eco houses are their quietness.  From their design and construction to their double glazed windows eco houses have the ability to reduce the amount of noise pollution which positively impacts on health and standard of living.

Sustainable homes also require less energy usage by using more natural light.  Well positioned windows can lessen the need for artificial light keeping energy expenses to a minimum.

Eco houses also take advantage of the natural landscape and work with the contours of the land requiring minimum excavation and earth moving reducing the amount of soil disturbance and pollution.

Health and living standards will continue to increase as eco house building becomes a permanent fixture of the construction industry. Eco homes may appear unusual and even more expensive than their traditional counterparts but this will soon change and more environmentally friendly housing will become an everyday part of the residential housing market.

Solar roof shingles are the answer to many homeowner’s dreams if they want to take advantage of solar energy without the characteristic bulkiness of traditional solar panels.

Homeowner’s wish to capitalize on solar energy without making too much of a dent in the way they live. This includes keeping in line with the design of their home which makes solar roof shingles a great alternative to regular solar panels.

What makes solar roof shingles such a popular choice amongst homeowners is their ability to mimic the look of regular shingles and blend in with the surrounding roofing system, this allows them to benefit from the financial savings that come from the solar power generated through solar roof shingles without the usual telltale signs that come from having traditional solar panel arrays.

Solar roof shingles closely resemble regular roofing shingles and are barely discernable from them, they also come in blue and black and can blend into the existing look of your home which is why they are known as building integrated photovoltaic shingles because of the ability of solar roof shingles to be integrated into the actual construction phase when building a home or the introduction of solar roof shingles should homeowner’s wish to take advantage of this option at a later date.

Solar roof shingles operate by acting like miniature solar panels with each shingle capturing and converting the energy of the sun ready for use.  Each shingle is comprised of a crystalline silicon substance and is around 12 inches wide and can generate up to 200 watts of electricity.  When a greater surface area is used such as the entire area of your roof with each solar roof shingle working in tandem with each other, can provide more than enough energy to satisfy your home’s energy requirements.  This is dependent upon the amount of sunlight captured by the solar roof shingles and on days of low sunlight levels, an auxiliary backup system is deployed to make up the shortfall.

There are several advantages of having solar roof shingles:

Having solar roof shingles raises the value of your home and makes an attractive buying feature amongst homebuyers because the cost is already added into the price of the home.   Plenty of homebuyers prefer to buy homes with existing solar power systems implemented than to go to further expense and trouble should they explore this option in the future.  They already know that buying a home with an existing solar power system will allow them to start saving money immediately making solar roof shingles a great financial investment.

At present there are 39 states that support alternative energy initiatives, in particular that of solar energy, putting more power back into the hands of residential homeowners.  This initiative allows homeowners to sell back their unused portion of power to the utility company on days where an excess is collected, for a credit.  This is essence means that your power is free making the initial installation costs of solar roof shingles, financially favorable.

If you are interested in renewable energy for your home but don’t want the telltale solar panels on your roof then solar roof shingles might be for you. Not only will you be doing your bit for the environment but you can maintain the aesthetics of your home. You can have the substance of solar energy going forward with the style of solar shingles to match the shape or color you desire.

Wind power is the quickly becoming the largest renewable energy platform in the world. You might see these wind turbine generators popping up especially in rural areas. This is a great resource that needs to be tapped into by more companies and individuals at least for partial power use. Wind turbine electricity is very economical, and earth friendly.

Winds are caused by the uneven heating of the environment by the sun, the changes in the earth’s surface, and the spinning of the earth. This is the information that is used to build wind turbines. Since the sun heats surfaces at uneven rates it forms pockets of hot air, and that hot air then rises up and this forces cooler air to rush in to fill the gap. This rushing wind is what creates the power to generate the electricity.

Blades are one of the most important pieces of the equation. Today turbines use blades that are horizontal, and there are usually only three blades. The metal cannot handle more than that as it is too much stress. The blades are made of a lightweight sturdy plastic or fiberglass, they are concave, and somewhat off center for a better angle for catching the wind and spinning the blades efficiently.

The blades are connected to a double rotor assembly, which then connects to a magnet rotor through a pulley assembly, which is used on larger turbines or can be placed directly on the smaller turbines used for homes. This assembly makes the blades turn.

The magnet rotor is not used to turn anything it spins about a magnetic alternator which in turn creates a magnetic field. When the magnetic field goes over the wires of the alternator, an electrical charge is produced. The electrical charge that is produced is carried into a regulator that converts the natural electricity into DC power for home use.

Now you have had a crash course in how a wind turbine works, you can imagine the potential. As you see it is a bit more complicated than one might first realize. It is however quite simple at its core. Harnessing the wind for energy use has been around for a long time. In days past it was used to turn wheels for different types of uses such as running a saw at a saw mill.

The turbines look futuristic compared to windmills of old with the three blades that are aerodynamic. They do have some similarities, but not the old world charm; however they are much more efficient for the needs of today’s communities.

Given the growing awareness that using fossil fuels may be causing to the environment and the fact that it is becoming expensive to use such fuels, people are looking to alternatives for their home power systems. Residential solar panels is one alternative that seems to tick all the boxes and is becoming increasingly popular. Not only does it diminish the degree of our fossil fuel dependency but it also affords us the opportunity to reap the financial rewards by using it. This article will run through some of the options when installing your own residential solar panels.

The advent of the internet has seen an explosion of information readily available to anyone wanting to learn how to install their own residential solar panels.  Making your own solar panels is labor intensive but can be financially rewarding while giving you a sense of achievement at the same time.

Because there has been an uptick in solar panel interest lately and because people are tired of being held ransom to rising energy bills, they are desperately looking for cheaper alternatives, hence the recent boom in the DIY solar panel kit market.

There is a wide selection of residential solar power kits these days and it’s no longer affordable to only a select few.  Gone are the days when you needed to outlay $20,000 just for the privilege of owning them in fact you can purchase your own residential solar power kit for as little as $200, a drastic price difference putting the technology into the hands of anyone wanting to gain the benefit from them.

Depending upon your budget, the varying materials that comprise your residential solar panels will have different price points and along with it they will also have varying levels of effectiveness.  Some of the materials that are used in residential solar panels are more efficient at collecting and storing the energy from the sun than others.  Just because you may not pay as much doesn’t mean that your solar panels will not be able to effectively harness and store solar energy, it just means that it does so at a slightly lower efficiency.  Don’t let this be a deterrent if you’re interested in solar panel technology because even cost effective solar panels are still effective.

When installing residential solar panels you can also produce excess energy that can be sold back to the power company, a definite advantage of going partially off grid.  The extra energy production can help fund the installation of even more residential solar panels enabling you to save even more money over time.  Not only does this feature of solar energy make it an attractive solution to your power needs but you also receive tax breaks and rebates allowing you to put more of that hard earned money back into your own pocket.

You can either find free information online or purchase a guide to make your own residential solar panels for free, however the better quality guides are the ones that you will have to purchase and the best solar panels are the ones that are readily made, the money you save creating your own free residential solar panels will cost you in extra time, so weigh up your options.

Whichever way you go, it seems that the future is very much a solar powered future. There is a groundswell of people interested in solar power and governments are making it more attractive to use such systems. Given that the costs of residential solar panels can only decrease as the costs of fossils fuels goes up, isn’t it time you looked into getting solar in your home ?

Solar power is one of the most unique, but beneficial ways of producing power on a small or large scale. Just like people would have wood or coal fireplaces to heat their homes in the past, the future will see each and every home have a small solar power system to power or at least augment the power they receive from the grid. This is provided that advocates of solar power electricity have their way and costs come down and incentives go up. Regardless of the politics, the fact remains that Solar power is a renewable energy source that has significant advantages over traditional fossil fuels. The only thing that counted against it was cost but this is changing. This article will examine some of the issues around solar power electricity.

One of the issues involved in producing solar power electricity is the initial cost.  Only specialist suppliers can obtain superior materials to produce the correct equipment needed, meaning low production volumes and high upfront costs.  On a similar note, installers of solar electricity systems demand extremely high rates due to their expertise making the possibility of affording a solar power electricity system, fairly slim.

In developing countries the necessity to hold fast to conventional non-renewable energy sources is far greater.  It may save them financially in the short term but comes with its share of disadvantages for the long term such as the contribution of greenhouse gases and the depletion of the very energy resources it needs to keep the engine of industry running.  It’s not that these countries are myopic when it comes to the global vision for sustainable, renewable energy sources but rather that the financial means to support the necessary infrastructure is simply not there.

It’s sadly obvious that it will be the established countries that will be in a better position to take advantage of solar energy systems.  While it may feel like the country is paying for 20 years of electricity in advance, apart from their maintenance, once the equipment is completely paid off, the power is effectively free.

Using similar systems for home use is also becoming somewhat of a phenomenon. Since the world wide economy has collapsed, consumers are altering their buying habits by becoming increasingly aware that they get the most economical cars, motorcycles and even light bulbs.  Economical and practical are taking the front seat in the importance of today’s buying decision over aesthetics and it’s only natural that consumers would want a piece of the action as far as solar power electricity is concerned.  The positive points are easy to highlight, but what about the negatives?

It does not matter whether systems are purchased in large or small volumes, they will cost a great deal either way.  Straight away this limits the number of potential consumers, but there are still other factors that might deter people from purchasing solar power electricity systems.  For a start most systems, such as panels or wind turbines take up a great deal of space.  If the consumer has the space and doesn’t mind it as a cosmetic feature, that’s fine, but people living in flats or apartments may find it difficult to install the panels due to planning issues relating to their block.

Given the advantages of solar power as a renewable energy source it seems that solar power electricity will play an increasingly bigger part in our lives as we move forward. By comparison, traditional energy resources can only go up in price making them economically less attractive than renewable options.

Creating photovoltaic solar panels is by no means an easy task, even the technically minded may find it a challenging feat to assemble from scratch.  It is a relatively new innovation in harvesting the Sun’s energy and has only been around for around 60 years. So there is not that much information on the subject and modification and improvement of the technology is an ever constant. With this said there are two ways that the average person can create photovoltaic solar panels. These methods can be termed semi-DIY and full-DIY. This article will cover how these processes work and how you can build photovoltaic solar panels.

However before we get into the details, lets discuss how photovoltaic (PV) solar panels work.

Although there may be a collection of other solar devices out on the market that have the ability to heat water for example, those particular mechanisms are unable to produce electricity. On the other hand the photovoltaic solar panels talked about in this particular case are those that have the capability to produce electricity or energy from sunlight. Most people can intuitively understand how heat from the Sun can be utilized but it’s not as clear how light can be used.

In professional solar panels, the material used in the PV cell reacts with sunlight of a certain frequency. This reaction ‘throws loose’ an electron. When many PV cells are connected from a negative to positive terminal, the negatively charged electrons flow to the positive terminal. This is an electrical current. This can be stored and used to power appliances or anything else that is powered by electricity.

There are basically two ways to approach this specific project.  People who intend to install photovoltaic solar panels in their homes can either choose between semi-DIY or getting it professionally installed. A full-DIY solution used copper to produce photovoltaic cells and is really a funky project to undertake but is not really a practical option to supply electricity to the home.

Semi do-it-yourself will require the purchase of solar panel kits and then assembling their parts. In most cases, these kits aren’t overly complicated and come with complete easy-to-follow step-by-step instructions.  These are recommended for those with moderate skills when it comes to handy-man work.  On the other hand, the full do-it-yourself photovoltaic solar panels are a little more complicated.  Advanced skills and a whole lot of patience are required to assemble a solar panel from scratch.

Semi Do-It-Yourself

There are a lot of places one can purchase a photovoltaic solar panels kit from. Some major hardware stores sell these types of kits but another option would be to purchase one online as the variety and model types are endless.  Most kits will come with mounting devices, installing hardware, wiring kits, and the photovoltaic cells themselves.  They should also come with either a set of video or print instructions. Some localities require that only licensed workers perform these types of jobs so it may be best to check first. You can also get guides or manuals that show you how to make PV cells but leave the sourcing of the materials up to you. The advantage of these guides over complete kits is that they are cheaper and generally suggest cheaper alternatives to find the materials than an all in one kit.

Full Do-It-Yourself

Creating photovoltaic solar panels from scratch will obviously require more work.  In a nutshell here are the few basic steps required to create a fully functional solar panel.

Firstly, you will need to obtain raw copper sheeting and then heat it for around half an hour.  This is to form a layer of copper oxide on the sheet’s surface.  After it cools, it should be kept along with non-oxidized copper sheeting.  A solution of salt water must also be added and the sheeting should be submerged in a split-proof glass panel.  The wiring would then need to be fixed and the mounting jacks put in place.  A normal household will need a number of these panels to ensure that enough energy is produced. These of course are just the beginnings of constructing photovoltaic solar panels.

More people are thinking about putting solar panels into their homes. This is becoming easier with the introduction of DIY kits or DIY manuals. There are also incentives to get professionally made panels. It seems pretty clear that this is a energy source that will be used by more and more households as we go forward.
