Guide on Residential Wind Turbine

June 28th, 2010 — 11:24am

Residential wind turbines are a wonderful model to produce a cheaper source of free energy. Knowing what to search for and where to buy one is essential in getting you started. If you are looking for a suitable residential wind turbine kit, the good news is that there is lots of places where you can do so. This is not something you can just get at a ironware store. Instead, a little searching have to be done first. In fact, the internet is one of the best places to find and buy residential wind turbines kits.

Assuming you have decided to purchase it online, there are a few points to check if it is a good bargain. You want to be positive you only purchase them online from a site that extends free transport though. Do not purchase them offline if the company does not provide free shipping. If not, the kit will be extremely costly with accumulated charges tallied on. On The Average, a rational price for a residential wind turbine should be around $300. If you find any sales where the cost deviates quite a bit you may want be be skeptical. It may be a scam.

A wind turbine is more commonly referred to as a windmill. It can also be referred to as a wind generator. Though the terms are used interchangeably, each is not the same as the other. What makes a wind turbine different from a windmill? For instance, a wind turbine converts wind energy into mechanical energy that can be further converted to electrical energy whereas a windmill will just use the mechanical energy as is. As a windmill does not convert the energy, it cannot really be considered a wind turbine even though the words are often used interchangeably.

Let’s examine the different types of wind turbines. Wind turbines are classified based on their orientation. There are two basic kinds of wind turbines known as the Horizontal Axis Turbine and Vertical Axis Turbines. The Horizontal Axis turbine contains blades that rotate across a horizontal axis. Conversely, The Vertical Axis turbine rotates its blade on a vertical axis. The Horizontal Axis Wind Turbines are more popularly used in various parts of the world. This is because horizontal axis wind turbines are more efficient than the vertical ones.

The advantages of installing a residential wind turbine includes saving power, cost effective, environmental friendly and perpetual power supply.

Some advantages of wind turbines include:

  • Perpetual power supply – You do not have to be dependant solely on the government for your power supply. Endless supply of power means never having to deal with a power outage too!
  • Saving Power- Wind turbines use wind energy to produce the same energy that we have to pay electric companies to use so we save power by not having to use regular electricity.
  • Cost Effective – Because wind is free, the only actual costs a user incurs is in installing and maintaining the wind turbine.
  • Environment Friendly – Wind turbines run on a natural energy source and are therefore not harmful to the environment.

The benefits of a wind turbine so attractive that everyone would want to install one, but if it is not correctly done, it can be quite bad. Before installing a wind turbine, do consider the following.

  • You must have at least an acre set aside to install it on.
  • Make sure the average wind speed is about 11 miles per hour.
  • Make sure the tower and base are ironclad. It is the wind turbulence that can mess up your wind turbine so take that into consideration as well.
  • Make sure that the distance between the wind turbine’s height and the wind generator and cells is optimal.

Wind Turbines Vs. Solar Panels

June 28th, 2010 — 11:21am

What will work better: residential solar panels or wind turbines for the residence? A great deal will be based upon the region where you live as well as the weather conditions there. Here we will check out the pros and cons of both starting off with the benefits of solar panels.

Solar panel pros:

1) Although commercial solar electricity systems are even now relatively expensive, the expenses are coming down. Best of all, your can assemble photo voltaic panels pretty easily and for roughly around $100 each. The actual construction of a photo voltaic panel is really really simple. You possibly have all or most of the tools you’ll have to have in your garage.

2) Solar panels are very easily added as time goes by. If you start with a smaller array, even one or two panels, you’ll be able to add to it as your time and money permit. Do not think as though you need to install an entire solar system to your property all at once. Get started now and at some point you’ll have a solar powered house. With every single panel you put up, you’ll have to buy less electricity from the utility company.

Solar panel cons:

1) Photo voltaic panels do not function at night. This isn’t a real disadvantage if you are still connected to the electrical grid. You’ll be able to buy electrical power at night and sell electricity you produce back to the power company in the day time. This ebb and flow of electrical power translates into no electric bill to pay each month.

2) Climate can be a limiting factor. Residential solar energy will work far better in Phoenix than it will in Seattle, but the fact is there’s adequate sunshine in almost every city and state inside the United States to make your own solar energy feasible.

Wind turbine pros:

1) Like solar, after your wind turbine for your residence is installed and operating, the maintenance is minimal. You can even construct your own wind turbine for under $150. Commercial wind turbines would cost a lot more, but if you know how simple they are to assemble there’s no reason to buy commercially.

2) Wind turbines for homes generate power day and night, whenever the wind is blowing. Like solar, some locations are going to be much better than others but wind power generators are absolutely realistic in most areas of the country.

Wind turbine cons:

1) A rooftop wind turbine could be a bird hazard. On occasion birds fly into the blades of rooftop wind turbines and are injured or killed. The hazard is really no more than the smaller windmills you see for irrigation on farms. The bird hazard is actually significantly more a concern with large wind farms situated in major bird migration routes like the ones in Southern California.

2) Wind turbine generators make noise. Unlike a residential solar panel which is 100 % silent, a residential wind generator will make a whoosh whoosh sound as it spins.

Whichever you decide on, photo voltaic or wind power, you’ll be a winner and so will the environment. You will have lower or no electric bills and there will be less carbon dioxide spewed into the atmosphere. And here’s a thought for your future: Nissan now sells an all electric vehicle, the Leaf, and many more car manufacturers will have them in the foreseeable future. Imagine never having to pay for gasoline once you generate your own power at home.

What to Know in Residential Wind Turbines

June 28th, 2010 — 11:19am

When you think about wind turbines, the tower with four blades reminiscent of Holland country landscape with the tulips and the Dutch gal is the first image that may come to mind. That image of a windmill seems a prototype of the mechanical wind turbine, also called aerogenerator that uses the wind energy to turn kinetic energy to electricity. It is also one of the mechanical inventions requiring great respect for it helps in alleviating the over-dependence of fossil fuels in generating electricity to power homes.
A distinction is to bring regards though in associating windmill with wind turbines. Windmill has mechanical purposes and that may not include generating electricity. The wind turbines, however, are invented to harness the strength of the wind to convert energy to electricity by turning the blades of the electric-generating wind system.

It may not be necessarily that huge to construct one unless you want megawatts of electricity to power a lot of machines in many households; that situation may need a behemoth one or numerous wind turbines beautifully lined up on a road or isolated locations to bring electricity to a whole town or a district of towns. The wind turbines may be humongous but seeing them collectively in an orderly, interval set-up makes them like the 8th modern wonders. These turbines have been utilized as a gradual replacement to the fossil fuels.

However, in the case of wind turbines for domestic application, the towering machines don’t have to be that big. A certain size for home use may be installed though. But, it is also important to note how much electricity you normally consume, as this will be a factor in availing a residential wind turbine with the appropriate capacity of the system for use in homes.

There are some things to learn about residential wind turbines. Although aerogenerator can be among the best machines that help lessen the amount of smokes fumed out from the power facility, using this at home is in simultaneous fashion with procuring electricity from local power utility at the beginning. The cut-in speed of wind turbines for homes is 7-10 mph. Below that speed is not sufficient to power a home, so it is better to have another connection of wires with electric power derived from the local power utility plant.

However, when the wind speed peaks up in the location of the wind system, enabling the turbine to roll its blades faster, the energy piles up converting to electrically charged current. As the turbine’s blades move at faster rotating speed and continuously, more and more electric current is made and the electricity may be enough to power homes, thus decreasing or eventually eliminating the dependence of power from the local power retailer. There can also be the tendency that the excess power produced from the turbine can be sold to the local power utility.

Residential wind turbine is an alternative medium to obtain energy to turn into electricity to power homes. This can be used as replacement to or in conjunction with solar panels, making your home environmentally friendly. This blade-turning machine with rotor and shaft may not even require batteries to make it work. Modern residential wind system eliminates the need for batteries and this is to watch out for when opting to acquire one or a set of required wind system.

If you desire to have a set of the wind machine system that helps generate electricity in your homes, make it a point to browse around. The best deals of residential wind turbines are just here for your purchasing decision.

Cut Your Energy Bill With DIY Wind Turbines

June 8th, 2010 — 1:42pm

wind-turbine-buildEnergy costs keep sky rocketing with no end in sight. Pollution levels are increasing and our planet is facing a warming trend that could have devastating results. So the question is what can the average citizen do to save money and help the environment at the same time? One great way to help is to lower the amount of electricity your home purchases from the utility company by creating your own power. There are a few ways to do this, and wind power is one of the easiest and more reliable ways to produce energy at your home.

What is a Wind Turbine?

A wind turbine is a simple machine that collects kinetic energy produced by wind currents and converts this energy into power that can be used in the home. Wind turbines are installed on high towers; these towers are usually around eighty to one hundred and twenty feet high. Towers must be high enough to allow the turbine to be above any turbulence generated by objects on the ground. The higher the altitude also results in higher wind speed and in turn, a higher amount of energy can be produced.

How do Wind Turbines Work?

Wind energy is used to create mechanical energy. Turbines have blades that are turned by the wind; these blades turn a shaft to which they are connected. The shaft is then connected to a generator; the mechanical energy is transferred into the generator through the shaft and converts the mechanical energy into electricity. This electricity can then be used in the home for any electrical need. Homes that are using wind turbines to produce power are still hooked up to the power grid. Being hooked up to the power grid allows the home to still have power when wind currents aren’t strong enough to produce electricity. Another benefit of continuing to be connected to the power grid is that at the times your wind turbine is producing more power than your home can use, the utility company is absorbing the extra energy and paying you for it. This can lead to very low electric bills. A wind turbine can lower your power bill by 50-80% depending on the amount of wind in your area.

Types of Wind Turbines

There are two main types of turbines: horizontal- axis turbines and vertical-axis turbines. Turbines also come in different sizes as well. Utility companies use wind turbines that can range in size from 100 kilowatts up to several megawatts. These larger turbines are found in groups on wind farms. If you ever drive over the Temecula pass in California, you can see large wind farms along the highway. It is a spectacular site. Small turbines, 100 kilowatts or less, are used at homes. These are place on towers on the homeowner’s property and then used to provide some of the energy needed to run the home. Since the size of the tower is quite large, they are usually used in areas where the home is on one acre or more. There are very small turbines on very small towers that may be able to be of use in urban areas or on smaller lots.

What Are Vertical Wind Turbines?

June 7th, 2010 — 12:10pm

wind-turbine-buildWhile the image we would all tend to think of when we imagine wind turbines is of large blades spinning in the wind like propellers run in reverse, this is in fact a form of wind turbine which has numerous engineering drawbacks. Many of these drawbacks, however, are corrected by turning the turbine ninety degrees, to create the vertical-axis turbine.

What is a Vertical Wind Turbine?

A vertical (or vertical-axis) wind turbine is a turbine that spins around an up-down axis, rather than a forward-backwards one. While the horizontal-axis turbine has familiar examples such as the windmills of the past, it is more difficult to imagine what a vertical-axis wind turbine looks like. One particular form of vertical turbine resembles an elongated water wheel turned on its side, with of a set of airfoils resembling cut-out tubes arranged in a bundle, with all the tube segments pointing the same way around the circumference. Others have fewer airfoils spaced further from the center and open space in the middle, like an oak barrel with most of its timbers removed.

Aside from the form of the rotors, the rest of the process is the same for any sort of wind turbine. The rotors spin a shaft, which connects to the generator through a gearbox, which increases the rate of rotation. Resembling electrical motors run in reverse, all rotary electric generators operate on the same principles.

What are the Functional Differences between Horizontal and Vertical Wind Turbines?

While horizontal turbines must be pointed in the right direction in order to capture the wind at any particular time, vertical turbines need no such adjustment they work equally well with winds coming from any direction.

Vertical wind turbines with relatively low cut-in speeds can be built which can produce electricity a greater fraction of the time. Compared to a horizontal turbine of equivalent power, the more compact vertical configuration takes up less space. Finally, vertical axis turbines tend to run more quietly than their horizontal counterparts.

Finally, vertical axis turbines are much better suited to be used in urban areas due to their compact form and ability to run at low wind speeds.

Wind Turbine Blade Design

June 6th, 2010 — 1:11am

wind-turbine-buildA new wind turbine blade design that researchers at Sandia National Laboratories developed in partnership with Knight & Carver (K&C) of San Diego promises to be more efficient than current designs. It should significantly reduce the cost-of-energy (COE) of wind turbines at low-wind-speed sites.

Named “STAR” for Sweep Twist Adaptive Rotor, the blade is the first of its kind produced at a utility-grade size. Its most distinctive characteristic is a gently curved tip, termed “sweep,” which unlike the vast majority of blades in current use, is specially designed for low-wind-speed regions like the Midwest. The sites targeted by this effort have annual average wind speeds of 5.8 meters per second, measured at 10-meter height. Such sites are abundant in the U.S. and would increase by 20-fold the available land area that can be economically developed for wind energy.

Sized at 27.1 meters – almost three meters longer than the baseline it will replace – the blade improves energy capture at lower wind speeds. Instead of the traditional linear shape, the blade features a curvature toward the trailing edge, which allows the blade to respond to turbulent gusts in a manner that lowers fatigue loads on the blade. It is made of fiberglass and epoxy resin.

“This design allows the blade to twist more than traditional designs, thus relieving some of the effects of gusty turbulent wind on blade life,” says Tom Ashwill, who leads Sandia’s blade research efforts. “This then allows us to grow the blade length for the same rotor, providing for increased energy capture of 5-10 percent and yet retaining the same expected fatigue life.”

Sandia is a National Nuclear Security Administration (NNSA) laboratory.

The K&C contract is part of the Low Wind Speed Technology (LWST) project that targets wind sites that are not the strongest but plentiful. In late 2005 the Department of Energy (DOE) and Sandia awarded Knight & Carver the $2 million contract that includes $800,000 in K&C cost share. Because of budget reallocations, this project was the only one of several LWST projects to receive 2007 funding.

Sandia’s role in the project has been in directing design and test planning. The K&C team provided the detailed design and blade fabrication.

The first STAR blade was tested in January at Knight & Carver’s fabrication facility in San Diego to determine its bending and twist behavior due to static loads. Natural frequencies were also measured. This data will be compared to design simulations to determine how well the design concept performs. Four additional blades will be fabricated in the first quarter of 2007 – three of which will be flight-tested on a turbine in Iowa.

“The DOE interest and funding are a big step for us,” Ashwill says. “We’ve been pushing for the incorporation of innovative concepts into utility-scale blades for some time now as a way of reaching program goals of lowered cost of energy.”

He adds that the continued increase in the average size of utility-grade wind turbines may come to an end before all efficiencies are wrung out unless blade weight growth (which is nonlinear) can be reined in. The challenge is to develop new concepts that reduce the rate of weight growth, such as the swept STAR blade.

Other weight-reducing concepts such as carbon spar caps, off-axis carbon fibers that facilitate bend-twist coupling, and new “structural” airfoils have been incorporated at a smaller scale in 9-meter-long prototype blade being flight-tested at Sandia’s test site in Bushland, Texas, at the U.S. Department of Agriculture ARS (Agriculture Research Station) facility.

Other members of the design team are Dynamic Design of Davis, Calif.; MDZ Consulting of Clear Lake Shores, Texas; University of California, Davis; and NSE Composites of Seattle, Wash.
