Wind Turbine Generators

Do you want to add a wind power system to your home to lower your energy costs? Does the thought of putting up a large tower with guy wires spreading across your property to stabilize it seem scary or not feasible? There are options available that will let you take advantage of the wind blowing over you no matter where live.

Vertical Axis Wind Turbines (VAWT) are systems that have helical shaped blades mounted vertically on the generator. They are specifically designed to address the unique problems associated with producing electricity in urban or suburban areas where often a horizontal wind becomes vertical when it encounters the face of a building. The helical shaped blades of the VAWT system utilizes vertical or horizontal wind bursts blowing from any direction (omni-directional). This makes it more efficient in these areas than the traditional roof mounted Horizontal Axis Wind Turbine (HAWT) available in most home wind power systems.

The HAWT systems work well in more open settings, a rural area without trees or surrounding buildings that break up the flow of wind coming to the blades. There are a number of smaller designs built specifically for home use, a lot of these are DIY kits that allow you to set up the system yourself, saving on the cost of professional installation.

Studies have shown vertical systems generate energy at a lower wind threshold than a comparable horizontal turbine. They also will produce power past the point that the increasing wind causes the blades of a horizontal turbine to feather to prevent damage from over powering the system. The larger, helical designed, slower rotating blades are also more visible to birds than the thinner propeller style of wind vanes used in a horizontal axis system. The Savonos style of vertical axis wind turbines can offer magnetic levitation instead of traditional ball bearings in the generator to blade interface, drastically reducing friction. The less friction, the less energy needed to turn the blades allowing the system to operate in lower winds.

Vertical versus horizontal. Which system to use? Each has their own pluses and minuses, and no one type will be perfect in all wind conditions for all sites.

Learn about the alternatives before purchasing. Start with the Internet to learn about the options, including information on siting, required permits and net metering available to add your system to the power grid. Knowledge is power. Your research will help you on your journey towards energy self-suffiency and improving your environment.

Vertical or horizontal axis. Learn about the various wind power systems available for home use and find the one that fits your personal environment; Rural, suburban or urban there is a wind turbine for you.
