Re: Wind in Houston
- I did a spreadsheet for the Honeywell generator using their published power curve and wind speeds from the NOAA at Hobby Airport.
The link will work for a year at most. I may change it as I improve the analysis.. You can look at the PNG or you can download the xls data for a closer look. I chose Hobby airport because it was the closest airport to my house with detailed windspeed data.
Windspeeds (column B) are in m/s. The annual energy column shows how much energy is collected at each speed, so you can get a pretty good idea of how much energy is captured at each speed.
If anyone has any ideas for improving the analysis I would love to hear them. I am not trying to make wind look good or bad, but rather I am trying to give a analysis that is open and verifiable, with supporting data rather than vague generalities.
Anyway, it works out to be about 547 kWH/year. This unit was the Earthtronics/Honeywell @kW unit, it's a low speed start up cowled design that will supposedly cost about $4500.
Summary - it's not as bad as you probably think, but it isn't spectacular either.
Have a good one!

In summary, there's not much wind in Houston. You need over 8 MPH to get significant power per wind swept area. Some turbines will spin at lower speeds, but their not making much power - just pin wheels.
