The UK Wind Power Backlash

Recent developments in the tidal power sector are causing many to speak out against the UK government’s reliance on wind power to ensure we meet our renewable energy goals. According to The Times, if the government wants to hit its target, the UK needs to build around 7,000 more wind-turbines – a high number if one considers the amount of not-in-my-back-yard-ism and anti-wind petitioning that meets nearly every planned wind farm.

However, as tidal power expert Bob Smith (of Pulse Tidal) argues, the backlash against wind in favour of tidal is not merely the voice of those who deem turbines ugly or a blot on the landscape – despite the fact that tidal turbines are out of sight. Quoted at edie.net, Smith commented: “Most importantly, the UK needs predictable sources of energy and tidal is entirely predictable, unlike wind; because water is more dense than air.”

Aside from making use of a more predictable energy source, tidal turbines can produce more energy from a smaller turbine system – resulting in lower installation costs. This is a positive factor that is highlighted by The Times’ article ‘Tilting at Wind Farms’ in which it is written that the Confederation of British Industry estimate that meeting the government’s 2030 carbon-emissions target will increase ‘the average British household bill from £1,243 today to £1,615.90.’

The same article goes on to quote Professor Jack Steinberger of CERN particle physics laboratory, Geneva. He argues that wind power is an uneconomic waste of resources – and explained his reasons to the Royal Society in May. Wind is now considered one of the most expensive forms of energy – costing six times the amount of gas and three times as much as nuclear.

In another twist in the renewable energy saga, even if the UK heeds the words of experts like Steinberger and Smith, wind energy may still be very much part of our future. Speaking in June, the Swedish Deputy Prime Minister announced that the country will soon be in the position to export wind power. The country’s economy, and rugged geography lends itself well to wind power – and is set to benefit further if other countries are willing to buy green energy from them.

Wind Power For the Home

The environment is in crisis, and the whole world is looking for alternatives to fossil fuel. Scientists are searching for options that are not only eco-friendly, but can be manufactured inexpensively enough to fit into almost any budget. Unfortunately, we’re lagging behind. The technology exists, but until perceptions are changed and more funding is given to alternative energy research, costs remain high for the average person to install most products that generate solar and wind power for the home, independently of public power companies.

The installation of a windmill has traditionally been a costly prospect. Even though installing personal wind power for the home will save the homeowner significant amounts of money in the long run, making the investment pay off in time, the initial outlay dissuades most people from the investment. However, there now exist very inexpensive – yet robust – solutions to providing homemade wind power for homes, allowing homeowners to see a return on their investment in a matter of weeks rather than years. Do-it-yourselfers will find excellent kits now available to help them harness wind power for their homes.

What to consider when purchasing a windmill

If you’ve made the decision to buy personal wind power for your home, you’re to be congratulated. Your decision will benefit not only you, but contribute toward cleaning up the environment in general – and on behalf of the rest of the world, thanks very much! We’re happy to see you eliminate your power bill and set the example for good stewardship in the process. Just remember that there are important things to consider before making your purchase.

Ideally, your windmill should be set up in a spot where the average wind speed is 11 miles per hour. Slightly lower speeds, however, are still reaping results for people, so it’s a judgment call.
Plan in advance. Decide how much output you want the windmill to generate – with such a small initial cost, it’s perfectly possible to buy 2 or even 3 windmill kits and still be financially ahead in a very short time.
Look for sturdy, robust components. If you live in an area that frequently gets heavy winds, you don’t want to risk damage to your investment.
Compare the price of the equipment available on the market, and opt for the one that best suits your site and budget.

What features to look for in a DIY windmill

Helpful illustrations. Seeing what the finished product is supposed to look like helps tremendously over relying on text alone. Find a kit that provides clear visuals and your project will go much more smoothly.
Well written guide. If the manual that comes with your kit is too technical, or simply poorly written, it will only create frustration. Be sure you find a kit with easy-to-read-and-follow instructions.
Component descriptions. Your guide should give you detailed descriptions (including pictures) of all the components you will need to install wind power to the home, including describing which components are best for your unique situation.
Local information. It’s a pretty poor guide that tells you all about where in Prague you can buy your equipment, while you sit reading it in Provo. Look for one that will provide you with information on equipment that can be purchased in your local area.

It’s not just possible to get inexpensive wind power to the home, it’s the smart move to make. For less than 0, no experience, and a few hours work, you can be lowering or even eliminating your power bill for good. With a homemade windmill, you might even find that the power company is paying you for the excess energy you’re generating! Live off the grid. Find out more by visiting http://howtowindpower.com

Wind Power Generators and Wind Turbines

Just like solar energy, the wind’s power also represents a very resourceful alternative rather than the use of fossil fuels. Taking into consideration that it is clean, cost efficient and most importantly it is renewable. By using turbines and wind power generators we can potentially collect this abundant energy and convert it into usable electricity.

For many years civilization’s have been embracing and harvesting wind power, so our generation certainly cannot take full credit as the use of wind power dates back for at least 5000 years give or take. In actual fact, generation after generation have used wind power for many things, such as creating ventilation in architectural structures, propelling sailboats, heat furnaces and even for providing mechanical power. On the other hand, in this day in age we have certainly found radical uses for wind energy which will and probably already has marked generations to come. Included among others are wind power generators, turbines and wind farms.

In order to appreciate the results we get from wind power generators we would firstly need to understand the fundamentals of wind harvesting. In essence wind is a natural flow of air which occurs in our planet’s atmosphere. Solar energy plays a huge part in this natural force, because this motion of wind consists of air molecules, when the sun warms the earth’s surface which warms and raises the air, different degrees of air pressure are created and as a result turns it into wind. Once the wind is in motion, particles then generate kinetic energy, which is then transformed into a more practical use with the help of a wind turbine. Once the blades on the wind turbine are spinning, with the use of a wind power generator the energy is then stored. This wonderful source of energy is now ready to employ without the emission of greenhouse gases.

Wind farms can create a much larger quantity of energy than stand alone turbines, but on a global scale people are beginning to recognize that DIY Windmills and turbines are very capable of generating power to our homes and our businesses. The rewards of constructing a wind power generator and turbine are plentiful. Obviously a combination of both wind power and solar energy together would give you the best results, while each method on its own can be plenty.

Both methods of generating power will give the user the freedom and savings beyond expectation. In fact one wind turbine is capable of powering most electronic equipment in the home. Once the user starts generating their own energy, it’s possible to generate more than required, this surplus energy can be sold back to the power companies, depending on which state or country you are residing in.

There are certain countries around the world, including the United States that recognize the rewards of green living and consider it to be a valuable investment. In many places there is vast accessibility directed towards businesses and homeowners who decide to take on renewable energy systems. So if you are one of those people considering building or purchasing a wind power generator, you may be entitled to some kind of federal subventions or tax cuts. Making the decision to generate your own green energy has never been more easier or rewarding. Lets face it, we owe it to ourselves and to our planet to contribute to a more positive, healthy future.

Wind Power Turbine

A wind turbine is a rotary device that extracts energy from the wind. If the mechanical energy is used directly by machinery, such as for pumping water, cutting lumber or grinding stones, the machine is called a windmill. If the mechanical energy is instead converted to electricity, the machine is called a wind generator, wind turbine, wind turbine generator (WTG), wind power unit (WPU), wind energy converter (WEC), or aero generator.

A wind power turbine is a large rotating machine that is able to harness the energy of the wind and turn it into a form that can be used by people. Historically, the most common type of wind power turbine was the windmill, which changed wind energy into direct mechanical energy, which could then be used for simple tasks like grinding grain. The modern wind power turbine tends to be a wind generator or wind energy converter, and is able to turn wind energy into electricity, which can then be transported over power lines to be used by individuals far from the location of the turbines themselves.

The earliest known wind power turbine dates from the 2nd century BCE in Persia, and was a very rudimentary design. By the 7th century, something approximating the windmill had been developed, and it spread throughout the world. This type of wind power turbine was used to turn mills for grinding grains, and also to operate pumps, allowing fresh water to be drawn up from the ground. Perhaps the most iconic uses of the windmill were in the Netherlands, where they were widely adopted by the 14th century to do everything from running gristmills to transporting water.

The modern wind power turbine is not that much different from a historical windmill, although it looks much sleeker and more aerodynamic. The most common type of turbine is a three-bladed horizontal-axis turbine, facing straight into the wind. Unlike vertical-axis turbines, horizontal-axis turbines are able to generate power through their entire rotation, never moving against the wind.

Although turbines can be quite simple, most modern turbines have a number of advanced features to make them function more efficiently. For example, most can be remotely adjusted, so that entire fields of turbines can be shifted slightly to make the best use of oncoming wind. Many modern designs also make use of variable-speed turbines, allowing them to shift their resistance and speed depending on the strength of the wind, and making them more efficient. Additionally, most modern designs also have emergency shutoff features, to ensure that they are not broken in extremely high-speed winds.

Wind Power Generators

Generators come in a lot of forms. There are solar, electrical, fossil fuel and wind generators. The source does make a difference in its operation and how it impacts the environment. In this time of extensive efforts to stop harming our beloved planet a wind power generators are the ones which leave the lesser footprint. The world has been dependant on fossil fuels for so long now that wind energy is considered new science though it has been around hundreds of years as the windmills in Holland can attest. Let us examine this wind power and see how it works.

A wind-powered generator has less moving parts than its fossil fuel cousins. It has the capacity to off set 1.2 tons of the damaging pollutants that are given off by the use of fossil fuels. This makes the air more breathable for all. Then there are the 200 tons per person green house gases released each year, producing electricity. With the wind power generators this is eliminated completely.

Wind energy is indeed a form of solar generated energy. It is the radiation of heat from old SOL that creates the conditions that make the wind we feel in the morning breeze or see sweeping across the rushes and moving in the trees. The sun heats different areas of the earth at different points in the day and because the heart absorbs heat at varying levels throughout its circumference hot air rises from the surface. This rising creates a vacuum, cooler air rushes forward to fill this void, this is what we have termed the wind. We have only scratched the surface of the forces potential as power generators. In the past it was used to run mills, water pumps and to power sailboats.

Harnessing wind power to create an abundance of electrical power is a new concept. The wind power generator is mounted on towers that are as much as 120 feet tall. Up in the air that high the turbines by pass most of the turbulence and gain greater access to wind currents. This in turn provides a better flow of kinetic energy through the turbines. The wind power generators convert kinetic energy to electricity. This can be used to power homes, plants and other buildings. There must be a secondary utility meter attached to each unit receiving this energy to make certain of the compatibility with existing wiring.

Homes are generally connected to both wind and normal power grids. This is a precaution in case there is little or no air current sufficient to power the wind generator. The best thing is that on those days that you are producing an over abundance the electric company is obliged to buy it from you its a law. If you do not sell it, there is the option of storing it in batteries.

It is recommended that only people with an acre or more of land in order to make use of these wind power generators. Also some localities have building codes. There is the FAA regulations and of course the expense to contend with.

Wind Power Generators

I wonder how you would react if your neighbour told you he was going to build a wind power generator for his home. You’d be pretty impressed, wouldn’t you? Well the truth is that it’s not that difficult to do and many homeowners are taking up the challenge to build their own generators as a cost-effective means of using non-polluting renewable energy. Building wind generators is not that difficult, as I said, but it’s not exactly snap-your-fingers easy, either, so you will need the right plans and instructions to get you powering along to success.

You really must purchase a good, detailed, but easy to follow instruction manual or guide so you know what you are doing and why. You know the old saying, “You get what you pay for,” well, it holds true for knowledge, too. If you buy a 4-page, $ 2 ‘manual’ you can pretty much expect to get into trouble, unless, of course, you have already built some wind power generators before and just need a ‘refresher’. There are also many online resources and forums to help guide you through your project.

Wind energy is the fastest growing source of power of any renewable energy sources and technologies, and you can embrace all its advantages with your own generators:

– wind power is clean

– wind power is free

– wind power is renewable

It will take a little bit of work to build your wind power generators, but there is nothing particularly complicated about it. You will need a good-sized work area, though, because your propellers or blades could get up to 8 feet in diameter (4 ft. blades), depending on your target energy output.

The surging interest in energy from the wind as a viable alternative to fossil fuel power has meant that building wind generators has become a fast growing occupation around the world because technicians are hard to find. Who knows, once you learn how to build wind generators for yourself you might want to make a career of it.

You can look into various websites that discuss the topic. It will be ideal to see pictures or illustrations of how everything works to give you better idea about the whole process. You can also read books that pertain to this subject. These contain deeper studies that have been conducted by professionals to give average people basic knowledge about the topic.

To help you with your learning venture, here are some quick facts about this energy source that is wind power.

1. Kinetic energy is formed when air moves that causes wind. This is the kind of energy that is created when mass is in motion. The kinetic energy coming from the wind can be captured using the right technology developed by humans. The captured energy can then be converted into various forms of energy, including mechanical power and electricity. During the early years of its development, people in Europe, Persia and China used windmills to capture the energy from the wind and convert it to power up grind grain and to be able to pump water. As of today, the more advanced wind turbines can be used as a stand alone to power up utilities and machines or can be used to support other systems like the solar power to create more energy.

2. The source of wind power is natural, clean and inexhaustible. This can actually be used for a long term goal for these reasons. This is also safe for the environment because not only this is clean, it also doesn’t cause pollution to soil, air and water. It doesn’t create wastes that are hard to manage like the wastes being created by nuclear power.

3. The location is the main problem that is usually encountered by those who want to build huge project to set up machinery for wind power. This must be done on areas that have large tracts of land. This can also be created along coastlines or in places where the wind movement is at its full force. These areas are usually devoted to the development of agriculture and urban growth and development.

4. Through time, people will realize how cost-efficient this project can become. There are various wind power designs that are continuously being developed to make the project more feasible as years pass by.

Wind Power

For quite a few years, the conservation of the environment has generated considerably concern and ultimately, plenty technologies were developed. This is the case of wind power. Formerly, we spent this source of energy for water pumping or grinding wheat to make flour. Today, this power source is still exerted to pump water but it is generally spent to cause electricity, without any negative effect on the environment. The favor in operating costs for nuclear and fossil fuels have also allowed wind energy to become exceptionally more competitive.
Wind energy has been exerted for some time. It is gathered when the wind pushes against a propeller that is to some degree bent. This forces all the blades to turn and siphon well water or turns a generator to produce electricity. There are two types of wind turbines, vertical axis turbines and horizontal axis. Nearly all wind turbines are horizontal. They have a few disadvantages, among others, the generator is located at the top of the tower, which makes it difficult to maintenance and repair. The vertical wind turbine, developed by the Canadians, has several advantages. First, access to the generator and the main mechanical components are located at the bottom of the tower. In addition, no system to navigate the direction of the wind turbine is necessary. This turbine is still in development, but it is anticipated that when fully functional, it will have a notable impact on the use of turbines for wind energy.
Wind power is extracted from a wind turbine and subsequently transformed into electricity by a generator. The generator current is sinusoidal and when plugged into the electricity grid, its frequency must be the same as the power grid or 60 Hertz. As the speed of the impeller determines the current frequency of the generator, it is needed that the turbine rotates at a stable speed. For this reason, much of the energy is not extracted from the wind. Presently, it is very important that a device operates at a very high yield. The same principle applies to wind turbines. In addition, researchers have found that it is possible to extract more energy from the wind by correcting the sinusoidal current in order to obtain a DC. Then, with the help of a converter, the current is transformed back into a sinusoidal wave but with a steady frequency of 60 Hertz. This means that the turbine can turn almost any speed and thus extract additional energy. Although the converter is often very complex and is expensive, the energy gain is worth the effort.

Wind Power

Wind power is the direct conversion of mechanical wind energy into electrical energy. Wind turbines can be used in wind farms on land, as offshore power generators, small residential power generators and more. At the end of 2008, worldwide capacity of wind-powered generators was 121.2 giga watts. Wind power has the capability of producing about 1.5% of worldwide electricity. Use of wind power doubled between 2005 and 2008, and now about 80 countries around the world use wind power on a commercial basis.

Wind farms are typically connected to local grid networks. Smaller wind turbines are used to provide electricity to isolated locations and for residential use. Small domestic wind turbines encourage utility companies to buy back surplus electricity.

Wind energy is attractive because of its renewable qualities. It is extremely plentiful, is widely distributed and very clean. One downside is the cost of constructing wind turbine farms. As with many other forms of power generation, the farms are not universally welcomed due to their visual impact.

Turbine wind power is non-dispatchable, which means that the available output of solar power must be taken and used when it is available since it is not possible to store the energy produced by wind power. Other sources, including hydropower, must be used to match supply with the demand. Wind power is considered to be intermittent, which causes problems when wind power is low in supply. When wind is used for a moderate fraction of demand, additional costs for the intermittency are low.

Wind power began to be used approximately 5,500 years to sail ships and produce wind-driven natural ventilation. The first practical windmills were built in the 1st century AD. While contemporary windmills have a horizontal axis, early windmills had a vertical axis. The first horizontal axis windmills were not developed until around 1180. Windmills and the “water-pumping windmill” allowed for the expansion of farming, ranching, and eventually the rail transport systems around the world.

Wind varies, which means that averages per location do not indicate the exact amount of energy a wind turbine could produce there. To decide how much wind occurs at a location, it is necessary to use the Weibull model, which closely mirrors the actual distribution of hourly winds at many locations. The Rayleigh Distribution system can be used as well, but is also considered to be much less accurate.

The maximum amount of power is generated by high wind speed, and much of the energy comes in short wind bursts. In fact, large amounts of wind energy can be collected in a mere 15% of operating time.

Wind energy is renewable, and while it may be intermittent, this rarely occurs and any problems can be balanced with other forms of energy. Wind energy does not deplete fossil fuels, continues to be clean, and produces no greenhouse emissions.
