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.

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!

windy, dustbowl areas might profitably include more wind power--

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.

interesting, thank you.
