Wind generator is a device that used to collect the kinetic energy from the wind and convert it into a form of energy to run your house appliances. This method is widely use for most of the house owners who have the desire to cut down their utility bills expenses or completely living off grid.
How much the home energy that you can generate for your house is heavily depending on your wind generator quantity and your geographic location. If you are not living in an areas that have a lot of strong winds, then it is wise for you to completely scrapped down your idea to use wind powers as your source of your home energy. As for the quantity, you need to be realistic.
homemade wind turbine
You don’t expect that your one wind generator would help you completely cut down your power bills by 50% or completely remove it. You have to take the account that wind is intermittent and very unpredictable. The results of the wind energy can be produced on every day are vary. So, keep it in your mind that relying on one wind generator to collect all the winds and convert it to run your whole house for every day is just insane.
There is a limit for one wind generator to produce the energy.Just as the old folks used to said, many hands make light work and faster. So, if you are serious about to cut down your utility expenses, put more effort and build more of your wind generators. You may spend more than $200 or more but the end justifies all since you still going to save a lot of money in the long run.
Building a wind generator doesn’t solve your home energy problem at once. You should aware that if you are a big energy consumer, you still have to pay more for your power bills. Don’t go nut to let your house appliances to run for whole days just because you have the wind generator outside your house producing electricity for you.
With the ever rising cost for electricity bills, harness the power of the nature like the solar and wind power is a common solution for most of the house owners. However, people prefer to build their own home energy generator because the cost of commercial home energy generator is expensive and usually out of everyone’s budget.

With energy costs rising as they are today, more folks are looking towards using little wind turbines, build own wind turbine to power their houses. This is a superb way to reduce your grid power consumption at home but there are a few things to be wary of.
If you don’t see full scale air turbines being built nearby, you may wish to rethink your green energy method, little air turbines will be far less efficient than large ones. Small Wind Turbine to Power HomeThese are freely available online and can provide an excellent concept about how much power you might generate from the wind. When you have an idea about the average wind speed, think about the size of turbine which will fit your property.
If you have masses of open space, you’ll be able to buy a larger turbine to take better advantage of the available wind. The most commonly available little wind turbines are rated at 250W, 500W and 1000W, but this doesn’t mean that they’ll always generate this amount of power.
wind speed measurement
The rating is generally for a comparatively high wind speed, as high as 30 mph. Most areas of north America do not have wind resources this powerful. This indicates that a 1000W rated turbine may only constantly generate 400-500W of power. Obviously if you would like to generate an important quantity of power from the wind, you are going to need more than one turbine.
Quite often there’s a negative link between power demand and wind speed. Many hot, wet summer days come with tiny wind. Working with these issues is the prime concern when coming up with your home replenishable energy system using small air turbines. Though the out of doors section of the system is the most obvious, the genuine wizardry occurs within. Elements like charge controllers, batteries and inverters give the chance for you to use the energy generated by your small wind turbine at some specific point in the future. This indicates that your turbine can be generating power in the middle of the night that you could use the following day. This is the perfect situation for using replenishable energy at home.
Commercially available small wind turbines are not the only real way to satisfy the necessities of your green energy system. If you want to tackle DIY projects, a wind turbine is not very difficult to build. When you create your own tiny wind turbine, you can figure out how much power it will generate and you can tailor it to your system. This advantage alone makes this project worthwhile for those that may handle it. If nothing available commercially suits your wishes, think about this option: build your own wind turbine!
Domestic, small scale, roof mounted wind turbines have a huge potential to contribute to localised electricity production, able to be installed on almost all varieties of roofs anywhere; although the degree of benefits associated will vary, depending on both the type chosen and location to which they are sited.
There are however a number of downsides to these small scale micro wind turbines, these are:
Vibration – As wind turbine consists of moving parts, this causes a degree of vibration to occur, which if mounted on the roof, is transmitted through to the building below, causing undue stresses.
build own wind turbine
Turbulence – Air passing over a building is distorted, resulting in cylindrical air movements. This interferes with the wind turbines normal operation resulting in increased stress and lower energy capture. This can be avoided however, if installed significantly above the roofline; however this is much more complicated and may negate any financial benefits. Or a sophisticated dampening system may be adopted, which separates the turbine from the building structure.
Safety – Turbines installed on roofs are a particular health and safety hazard, with higher risks associated due to their placement within close proximity to occupants. Their fixings need to be strong enough to withstand high wind levels, and noise levels minimised.
Efficiency – The majority of residents currently live in built up urban locations, which are sheltered areas, and consequently experience high degree of intermittent wind speeds. The average wind speed in a town or city is generally a lot less than for the same turbine in a rural and open location.
Financially these turbines are not currently viable for the mass market, however with increased grants becoming available, this situation may be changing, and if the price is cheap enough, these issues mentioned above may not necessarily be a problem.
The cost effectiveness may be increased through clever use of energy storage from the turbines, such as an electric immersion heating element in a water tank may be used, reducing the impact of intermittent electricity production, and making it more viable a source to meet a home’s energy needs.
Although this article emphasises generally negative aspects of wind turbines, it needs to be appreciated, that presuming that are installed correctly, they can provide signficant cost savings, contributing significantly to Homeowners annual energy bill. More information found on Wind Turbines here.
How to Build Own Wind Turbine – Step by Step Instructions
Step by Step Instructions for making your own 4/6 foot Wind Turbine
To build own wind turbine from used materials is something useful and very environmental oriented. It shows how much we care about our environment. Most of the tools and materials you need, can be found in your local hardware shop or junk pile. We highly recommend you search your local dump and/or junkyards for the materials required. The wind turbine built with these instructions, used the motor on eBay for $10 plus shipping and the PVC pipe for the blades from a junk pile. The tail is made from an old roller paint pan.
Safety should be your highest priority. Human life is more important than electricity, so please work safely.
SUPPLIES
build own wind turbine
A 260 VDC, 5 A continuous duty Treadmill Motor with a 6 inch threaded hub is best suited for a small wind turbine. These motors are available from most motor surplus stores and on eBay. You can get about 7 amps in a 30 mph wind. In other words, it is a simple, cheap little machine to get you started.
You may use any other simple permanent magnet DC motor that returns at least 1 V for every 25 rpm and can handle upwards of 10 amps. If you do, there will be certain changes to this supply list, for example, you may need to find a hub – a circular saw blade with a 5/8″ shaft adaptor will usually work well as a hub.
Tools
Drill & Bits
Jigsaw with a metal blade
Wrench
Flat Head Screwdriver
Crescent Wrench
Vise and/or Clamp
Wire Strippers
Tape Measure
Marker Pen
An extra person helps a lot!
Mount
Square Tubing or “L” tubing
Floor Flange – or a rotating dolly wheel with a hole in the centre (picture the wheels on a grocery
4 inch Nipple
3 X 3/4 Self-tapping Screws
Note: if using a dolley wheel, you won’t need the nipple and flange as the dolley wheel bolts to the tower and to the DC motor directly.
Motor
260 VDC, 5 A continuous duty Treadmill Motor with a 6 inch threaded hub
30 – 50 Amp Blocking Diode (one-way)
2 – 5/16 x 3/4 Motor Bolts
PVC Pipe – to cover the motor
Tail
1 sqft (approx) lightweight material (metal) – used roller paint tray will work
2 – 3/4 Self-tapping Screws
Blades
24″ length of 8″ PVC Pipe (if it is UV resistant, you will not need to paint it
6 – 1/4 X 20 Bolts
9 – 1/4 washers
3 sheets A4 paper and tape
Cutting The Blades - makes 8 blades (or 2+ blade sets) and a thin waste strip.
Read through the instructions a couple of times. I have created a separate page, with pictures, and expanded on this process for making the blades as itcan be difficult to understand these instructions without the illustrations. See the link at the bottom of this article.
Place the 24″ Length of PVC pipe and square tubing (or other straight edge) side by side on a flat surface. Push the pipe tight against the tubing and mark the line where they touch. This is Line A.
Make a mark near each end of Line A, 23″ apart.
Tape 3 sheets of A4 paper together, so that they form a long, completely straight piece of paper. Wrap this around the section of pipe at each of the two the marks you just made, one then the other. Make sure the short side of the paper is straight along Line A and the paper is straight against itself where it overlaps. Mark a line along the edge of the paper at each end. Call one LineB and the other Line C.
Start where Line A intersects Line B. Going left around Line B, make a mark at every 145 mm. The last section should be about 115 mm.
Start where Line A intersects Line C. Going right around Line C, make a mark at every 145 mm. The last section should be about 115 mm.
Mark each line using a straight edge.
Cut along these lines, using the jigsaw, so that you have 4 strips of 145 mm and one strip about 115 mm.
Take each strip and place them with the inside of the pipe facing down.
Make a mark at one end of each strip 115 mm from the left edge.
Make a mark at the other end of each strip 30 mm from the left edge.
Mark and cut these lines, using the jigsaw.
Sanding the Blades
You should sand or grind the blades to achieve the desired airfoil. This will increase the efficiency of the blades, as well as making them quieter. The angled (leading) edge wants to be rounded, while the straight (tailing) edge wants to be pointed. Any sharp corners should be slightly rounded to cut down on noise.
Cutting The Tail
The exact dimensions of the tail are not important. You want about one square foot of lightweight material, preferably metal. You can make the tail any shape you want, so long as the end result is stiff rather than floppy.
Drilling Holes in Square Tubing – using the 5/16″ drill bit
Place the motor on the front end of the square tubing, so that the hub part hangs over the edge and the bolt holes of the motor face down.
Roll the motor back so you can see the bolt holes, and mark their position on the square tubing.
Drill a 5/16″ hole at each mark all the way through the square tubing.
Drilling Holes in Blades - using the 1/4″ drill bit
Mark two holes at the wide end and along the straight edge of each of the three blades. The first hole should be 3/8″ from the straight edge and 1/2″ from the bottom. The second hole should be 3/8″ from the straight edge and 1 1/4″ from the bottom.
Drill these 6 holes.
Drilling and Tapping Holes in Hub - using the 7/32″ drill bit and 1/4″ tap
NOTE: You may want to modify these instructions. Try replacing the hub with an old, used 7 1/4 inch skill saw blade. The larger surface area will give you more space to screw or bolt the blades to. I also used 1/4 inch bolts rather than tapping holes. I’ve also see old aluminum frying pans used for this purpose. They are light and solid!
If the Treadmill motor comes with the hub attached, take it off, hold the end of the shaft (which comes through the hub) firmly with pliers, and turn the hub clockwise. This hub unscrews clockwise, which is why the blades turn counter-clockwise.
Make a template of the hub on a piece of paper, using a compass and protractor.
Mark 3 holes, each of which is 2 3/8″ from the center of the circle and equidistant from each other.
Place this template over the hub and punch a starter hole through the paper and onto the hub at each hole.
Drill these holes with the 7/32″ drill bit.
Tap the holes with the 1/4″ x 20 tap.
Bolt the blades onto the hub using the 1/4″ bolts. At this point, the outer holes have not been drilled.
Measure the distance between the straight edge of the tips of each blade. Adjust them so that they are all equidistant. Mark and punch each hole on the hub through the empty hole in each blade.
Label the blades and hub so that you can match which blade goes where at a later stage.
Remove the blades and then drill and tap these outer three holes.

Build own Wind Turbine: as energy costs rise and we become more aware of our responsibility to develop alternative energy sources, more home owners are considering DIY wind turbines and DIY solar panels for their home. For a relatively small amount of money, you can now generate your own electricity and not only save yourself money but do your part in protecting the environment as well.
DIY alternative energy projects are very inexpensive and easy to build. Anyone can construct a wind turbine for less than $200 and provide all the energy needed for an average home. Solar panels can be built for less than $200 as well. Linked together these panels will generate electricity for your home. Everything you need can be purchased at your local hardware store or home improvement center and the tools required are probably already in your toolbox.Just about any able-bodied person can get a hold of the necessary plans from the Internet for less than $50 and use those plans to construct wind turbines and solar panels.
Some even come with videos that will walk you through the process step-by-step. So if you are intimidated by working with your hands to create a DIY wind turbine then don’t be… it is definitely something you can do.Manufactured wind turbines can be purchased, but they are extremely costly. For those who are absolutely convinced they cannot build their own turbine or who dont mind spending thousands of dollars to buy a readymade turbine can do so. But chances are, if youre reading this article, you think a DIY windmill project is within your capabilities and might even be a very satisfying undertaking.
There is no question that you can save money by generating your own power. In addition to saving on your monthly power bill, tax breaks are available to those who use wind and solar energy. When you file your taxes you can take a deduction that will lower your tax liability. Alternative energy sources available in a home also increases the value of the home.People throughout the world are turning to renewable energy options. Home owners in civilized countries everywhere are building DIY wind turbines and solar panels and reaping the benefits in lower energy costs. They are saving money and happily doing their part to reduce their carbon footprint on our planet. This trend promises to continue into the future with more and more people creating their own energy.
You may be wondering how much energy you can produce with a DIY wind turbine. This will depend on several things. First, the amount of wind in the area in which you live will play a big part in how much energy you can generate. The more wind the more power. Secondly, the size the wind turbine itself will determine the amount of energy that can be captured for future use. An average sized DIY wind turbine can produce enough energy to power an average home with just a few hours of moderate wind.A wind turbine generates electricity through a simple process. As the wind turns the blades on the windmill, kinetic or physical energy is created. This energy is then trapped and stored in a battery where it can be used whenever it is needed. With this stored energy, the wind does not need to be blowing in order to have a supply of energy.
A DIY wind turbine can save the average individual up to 80% on their power bill. Some people can generate enough power to provide electricity for all of their needs. Those who have the perfect set up are able to create more than enough energy. The excess energy can then be sold to the local power company to create income. In the best case scenario you will not only save money, you actually make money.
