Free wind energy is a good solution where wind is in sufficient supply.

Modern DIY wind turbine construction is a vastly different proposition to making a traditional windmill.Bulky structures are a thing of the past and the windmill is replaced with state of the art technology that generates electricity efficiently for the home and small cities. Don’t misinterpret these developments as putting the construction required beyond the skill level of the average home owner.

The basics are finding a site that has a regular supply of wind that cannot be affected by trees and surrounding buildings. The lightweight construction of modern generators means they can be fixed to the roof of the home, and little noise or vibration will disturb the inhabitants.

Anyone considering a DIY wind turbine will need only the usual tools in the workshop and a few hundred dollars for the complete unit. Even less if materials are available from a recycling center.

What most people don’t realize is that there are few moving parts in the modern turbine and lighter weight construction means no need for a high tower to support the generator and its blades. Build a secure frame on the roof, and a site for a DIY wind turbine is available

Admiring your wind turbine

DIY wind turbines come in all makes and sizes, so getting one for a specific site, and the amount of energy required will be time well spent. Investigation into local building codes, noise limitations, and things such as height and where the prevailing wind will come from are almost more important than knowing how to put the unit together.

The installation may take only a few days, unless you are thinking of building everything from scratch. Blades are the driving force and those from wood or fiber composites are cheaper and less prone to vibration and noise than metal ones. A tail assembly to keep the unit facing the breeze can be made with simple woodworking or engineering skills to make a DIY wind turbine fully efficient.A tower may be required if the home is at a low point in a dip, and checks should be made for any building height restrictions that may apply in the district. The next step in make wind generator is to decide what output is required and this should be done after the whole household has been energy audited.

Gearing and the DC motors can be purchased online and bolted together.Assembling of the gearing, tail assembly and generator is a task for more than one person due to the awkward nature of the windmill. Wiring and connection of the motor to turn the energy into electric power may require an electrician to make the connections, especially if there is an intention to supply surplus energy to the grid for credit. A wiring plan may confuse those unfamiliar with electricity, but it is worth involving an electrician at the final stages to give an ok to the home handyman’s work.

Most of this seems to be simple and it is. A DIY wind turbine is not a toy though, and access to it should be restricted. The blades can be fatal for children and adults alike, and any electrical installation should be well insulated. If the unit is mounted on a tower this should not be able to be climbed by the adventurous. Use fencing to deter potential climbers and security lighting to scare away those thinking the structure is an advanced playground.

Windmills have been with us for several hundred years in countries such as Denmark and Holland, but these were simple geared systems for grinding grain. The pity was that much of the knowledge was lost for generations of people when electrical generation from fossil fuels became the cheapest option. That today making wind generators is coming back into fashion seems to be a twist on ‘back to the future’. As the units are more popular, the price begins to drop and some states offer subsidies and grants due to the environmental benefits.
