How To Build A Windmill Yourself

These days a manufactured windmill is likely to cost anything from $10,000 to $30,000 (or more), even for a domestic installation. The capital cost of going green is very high, so perhaps now is the time to think about how to make a windmill yourself.

Building a windmill yourself is easy and straightforward. There are plenty of people who claim to be able to make a windmill for less than $200. This kind of money will not get you a grand structure, but the potential utility bill savings are really significant.

But before you actually start building your windmill you need to do some research about:

Building Codes
Wind speed history
Space available
Next door properties
Windmill size
Power storage

So what steps do you have to take when planning to build a windmill yourself?

• Building Codes. Find out if you will be allowed to build the type of windmill you want. For a small machine you probably will be OK, but it’s best to make sure first.
• Wind speed history. In spite of what others might say, homemade windmills do not work well in average winds of less than 10 mph. The US Government publishes detailed wind resource maps, which are worth checking for your area before you build your own windmill and then find it is often stationary!
• Space available. Plan on roughly half an acre of clear space for a small windmill.
• Next door properties. Talk to your neighbors about your plans, and be prepared for any objections to potential noise from windmill electricity generation, interference with TV reception and similar concerns.
• Windmill size. The generating capacity of your windmill should not exceed your electricity consumption. The utility company will not buy any surplus from you, only offset against any power you draw from the grid. This is not generally appreciated, although moves are afoot to encourage the introduction of tariff legislation so that utility companies will have to buy all surplus electricity in the future.
• Power storage. If you want some independence from the grid you will need to include storage batteries in your home windmill system. These can cost you nothing if you know where to look. Or you might decide to use your windmill simply as a way of reducing your draw on the grid supply.

These and other considerations make it sensible to get some guidance and advice from experts in alternative energy design and construction in the early stages of planning how to build a wind mill. You will then be able to select the right plans for your circumstances, and you need to make sure these include full lists of materials for the assembly as well as clear-step-by-step instructions to avoid any tricky situations during the build.

Small home windmills have only a few simple components. Typically these include:

• A propeller (usually 3 blades fixed to a hub)
• A DC motor
• A fantail
• An axle to which these are fitted
• A mounting beam for the assembly
• A tower or mast
• An inverter, if AC is required
• Storage batteries

With some electrical wiring and a few fasteners you will have everything needed to build your own windmill. You probably have most of the necessary parts in your shed but, even if you have to buy everything, you will find it possible to get all required items for under 200 dollars. Putting them together and installing the turbine on your site can be done in a weekend, and it is usually great fun.

Switching on and seeing your first free electricity is awesome!
