The growing need for clean, renewable energy sources has been a concern for many years. New technological developments in wind energy systems and increasing problems with our current power plants can only lead to the conclusion that clean alternative energy must be the way for the future.
Problems with Existing Energy Sources
Most of our energy is currently created using coal, gas, oil or nuclear power. These methods damage the environment and use huge amounts of water in the production process. With many areas suffering critical drought and low water tables, water needs to be conserved and used as efficiently as possible.
The United States imports more gas and oil than any other nation. Many of its suppliers are in troubled and unstable areas. Placing the nation at the mercy of these countries by being dependent upon them for essential power has many undesirable political and social repercussions. Being self-sufficient as a nation by generating wind power energy locally can significantly contribute to the security of the nation.
The Pros of Wind Energy
Wind energy creates electricity from the wind, so that it can be used as a power source. Spinning wind turbine blades rotate with the wind to turn a generator and the energy of motion is converted into electricity. A concentration of these wind turbines placed together is called a “wind farm.” Unlike traditional energy production, wind power energy can be produced and consumed in dry areas and in times of drought, conserving water for other essential uses.
Wind power is known to have little or no damaging effect on the environment compared to other energy sources. Emissions are negligible as no fuel is combusted. The mass production of clean energy using wind power has the potential to reduce global warming. It can reduce pollution known to cause acid rain, smog, haze and the high mercury contamination currently found in our water supply.
wind farm
Wind farms can be located offshore or on land, and the land can still be used for grazing livestock or farming. Wind energy was harnessed and used in ancient civilizations but during the Industrial Revolution, for economic reasons, oil was seen as a cheaper way to obtain energy.
Coal, gas and oil prices have now rocketed. Once wind power energy has been established, it could stabilize energy prices. With the new wind turbine technology now available it makes renewable wind energy the cheapest and most economical way to create clean energy for all.
It doesn’t really matter what subject you talk about there are always people who are going to have different opinions. Whether or not you should build your own wind turbine is one of those subjects.
There are thousands of people who have taken the plunge and built their own, there are also many people who think it’s a waste of time.
I don’t know the technical aspects of how a turbine works. I do know that the energy of the wind is converted to electricity which is then used or stored in a battery for later use.
Turbines do come in sizes small enough for you to use in your own backyard. They also come in different shapes even though the most common is the wind mill style. You can build your own turbine in a couple of days for a few hundred dollars, all the parts you need can be found at your local hardware store. Many homeowners have had savings of up to 80% off of their electric bills.
The downside of building your own turbine is the upfront expense and the time. It’s also important to note that while one turbine can help you save money on your utility bill, it won’t supply enough electricity for all of your household needs. You will still need to pay for some electricity from your utility company.
Of course in order for your turbine to work you will need wind. Since it’s not going to be windy every day there will be days when you won’t generate any electricity. In this case you could supplement the electricity from your turbine with solar panels, geo-thermal, or other forms of renewable energy, or just buy it from your utility company.
For most people the relatively small investment in a wind turbine is a good investment. While it won’t be enough to get off the grid, it will give you some control over your utility costs as well as bragging rights to all of your friends.
I like to write about anything to do with saving money and the environment. I hope you get some good tips from me and enjoyed your visit.

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!
Read on to learn about the advantages of owning a mini wind turbine.
Power prices are continually rising. The best way that you can combat this is to make use of green power sources. Using wind to create power is one of the most simple and reliable solutions available. Building a windmill will allow you to harness the power of the wind and use it in your home.
More individuals are discovering the benefits of homemade windmills to power their plates and are enjoying the free electric that they make.As the end of oil crisis nears, more and more individuals across the United States are turning to wind power to make power for their plates.
How Does an Electricity Producing Wind Power Generator Work?
Just as the larger windmills typically used in wind farms switch wind into electricity home built windmills are no different. How this is done is by utilizing a motor generator to switch wind force into electricity.Windmills store their excess electric energy in batteries.Using the power contained within these batteries you can power your home and all of your appliances just as you normally would.
There Are Significant Differences Between Homemade in Commercially Made Wind Generators You don’t have to build your own wind generator because you can buy one if you prefer.If money is not an issue to you, this may be the best option for you.Commercially constructed wind generators pricethousands upon thousands of dollars. The homemade variety is much more price effective than you can build one for under $200. This includes the price of materials. Many individuals do understand that they can create their own windmill in just a few afternoons of effort.
Mini wind turbine are getting more popular every day.
The Secret to a Good Homebuilt Wind Power Generator
The best way to create a homemade wind generator is to ensure that you have detailed step-by-step plans to follow.Detailed step-by-step instructions are inessential necessity when making your own home windmill. It also lists and illustrates the materials and tools needed to build your own windmill. Be wary of the free windmill plans you may find on the net, because you do get what you pay for.Insure that you chooseplans from a company with an incredible reputation and a good track record. A mini wind turbine is easy to build if you start with a great set of plans.

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.
You Can Build Your Own Domestic Wind Turbine…Easily
If you are like so many other people who are just getting fed up with the way the huge energy companies are treating you, and you want to do something about it, I’ve got great news. You can easily and inexpensively build your own domestic wind turbine to generate electricity for your home.
Wind power has been around a long time. Even in modern times we’ve seen the huge turbines spreading over acres of farmland in many parts of the country.
These turbines are the ‘tools’ needed to convert the power of the wind into electricity. Due to limitations in technology, you needed a huge turbine to generate enough electricity to make it economically feasible.
That is one of the reasons why you haven’t seen turbines in backyards across the country…until now.
Due to technological advances it is now possible to generate respectable amounts of electricity even from one small, ‘home sized’ turbine.
build own wind turbine
One turbine still won’t be enough to generate all the electricity your house needs, at least not yet, but it can generate upwards of 60% of the average homeowners electricity. And it’s all free.
Homeowners are routinely seeing a decrease on their utility bills of around 80%. That can really add up over the course of a year, or 10 years.
It’s very easy to build your own turbine, anyone can do it. For most people I don’t recommend buying a turbine, it is so expensive that it will take you a long time to get your money back.
But if you build your own turbine you can usually recoup that investment in a few months.
So to recap, you can easily and cheaply, for $200 or less, build your own domestic wind turbine. You will save thousands of dollars on your utility bills for years to come.
And the best part? You won’t be sending such a big check to your greedy utility company every month!

Looking for inexpensive, yet effective, alternative energy sources is becoming extremely popular for many homeowners. This is due in equal parts to the rising energy costs as well as a desire to go green.
The good news is that building a DIY wind turbine is not only feasible, it’s inexpensive and effective at supplying much of the electricity your home needs.
Today you have a choice on the size of the turbine you choose as well as the shape. You can use the traditional windmill style turbine or a newer, cooler looking, vertical turbine.
Many mistakenly believe that it will cost a lot of money to build a turbine. That simply is not true.
It is true that if you wanted to buy a turbine it would probably be cost prohibitive. Buying a turbine will cost about $1,000 or higher. Building your own will only cost a few hundred dollars at most.
made own wind turbine
All the parts you need can be bought at any hardware store. It should only take you several hours, or one day, at most to build your turbine.
It doesn’t matter if you want to build a windmill style turbine or a vertical style turbine, you can use the same plans for either type.
A vertical style turbine has the advantage of allowing you to use more blades in the design without making it take up more space. Having additional blades will allow your turbine to be more effective because it will be even more sensitive to less wind.
So do yourself a favor, build a DIY wind turbine. You can do this project easily and it won’t cost you very much. The advantages though are many: you’ll pay less on your utility bills, and you’ll be helping the environment, to name just two.

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.
