Wind Power Systems

Wind Power Systems

Sunlight, wind, and falling water are the big three renewable energy sources. These are energy sources that are commonly available at a reasonable cost. We’ve found in our years of experience that wind and hydro energy sources are most often best developed as a booster or bad weather helper for a solar-based system.

Hybrid systems—using wind or water combined with solar energy—have the advantage of being better able to cover power needs throughout the year, and are less expensive than a similar capacity system using only one power source. The only common exceptions are systems designed for utility intertie; they feed excess power back into the utility, and turn the meter backwards.

  • We generally advise that a good site for year-round wind turbine energy isn’t a place that you’d want to live! It takes average wind speeds of 8 to 9 mph and up, to make a really good resource for energy. That’s honestly more wind than most folks are comfortable living with.
  • This is where the beauty of hybrid systems comes in. Many very livable sites produce 8 mph or more during certain times of the year, or when storms are passing through, and this wind can be harnessed.
  • Tower height and location also make a big difference. Wind speeds average 50 to 60 percent higher at 100 feet compared to those found at ground level.
  • The cost of a wind power system includes the cost of the wind turbine itself, the tower, and its installation. The total cost of micro turbines can be as little as $500-$1,500 depending upon the tower used and its height. Bigger machines are more costly, but can be more cost-effective.

The Sourcebook remains the best introduction to energy-efficient technology for common folks.
-Whole Earth Review

From novices to pros, this book explains renewable energy and efficient building practices. Great reference to start design and cost estimation from each section. One of the best features of this book is the addition of the National Electric Code for RE systems. It's possible to pick a building material to build a house, design a solar electric system, decide on appliances, determine the use of a greywater system, and more from 562 pages.

I support the Clean Energy movement via the purchase of 100% wind RECs (Renewable Energy Certificates) since I cannot afford solar panels or my own turbine for my home yet. Check this out! www.lewiscolon.cleannation.biz

We should all mount mini-turbines on our homes. The mass market would bring the prices down and standardization would make maintenance and repairs easily doable while offsetting some of our individual costs but a very large collective amount.
