With ever-increasing utility costs, knowing how to make a windmill for electricity to accommodate a home’s energy needs can be a smart decision to make. Over the years and decades, engineers and others quickly began to realize that harnessing the wind’s potential energy to turn an electrical generator showed great promise. The refinement and improvements to these wind-driven power plants continues even today. Some are massive in size, while many more are of small, efficient and personal dimensions.

Wind Power Today: Windmill production techniques are vastly improved these last few decades. This serves to also make a good windmill cheaper and cheaper all the time. And home-built kits are less-expensive still. And as they’ve become less-costly, they’ve also become more efficient, and can oftentimes power a whole house. A factory-built unit may be high-priced, but many windmills can be made for as little as two-hundred dollars. If you’re an intelligent owner, you’ll look at the possibilities in using one.

Cautions: Take care to always buy an illustrated set of plans, and use the proper materials and tools. They’re not hard to build, but find the best sources for materials, and work methodically through the process. Most of the items in a windmill system are either very inexpensive or free, so don’t feel any pressure to buy really expensive parts.

Windmill Components: Windmills have only a few basic components. All will have a fan system of some type, usually with several blades. The best ones have a radius of about four feet. These fans are connected to a motor that generates direct current (DC). The fan and motor sits atop a small tower, about seven to fifteen feet above the ground. Also, ensure a rudder’s been connected to the rear of the motor. This will enable the fan to always face into the wind, as the motor rotates on its axis.

Power Collection: Once the motor generates power, it has to be stored in some capacity. Generally, a bank of batteries serves this purpose. They hold power for future use in the house.

DC to AC Power Conversion: All mills need to use what’s called an “inverter.” This device converts the wind-generated DC power over to usable household AC (alternating current) power. Also, make sure a controller module is used. It prevents the batteries from being overcharged by the DC motor.

Watching Your Power: Many meters exist which display battery power available for immediate usage. They show power in the batteries themselves, and also show how much power is being used in the house right at that point in time.

System Complexity: A wind-powered household mill system can be as simple as that. You can also run it separately from the local power grid, or use it to supplement the power you derive from electricity power lines and the like. Also, tying in solar panels to the windmill system can help you make and store power on windless days. At the very least a good windmill-power storage-power conversion and monitoring system will lessen the cost of purchasing electricity by a significant amount.
