[font color="green" face="Verdana"]I love this! A recent article I saw somewhere said that wind power in the U.S. is growing fast and making a real mark.
Can't wait to see more of this! It's absolutely beautiful.

(20,885 posts)Did you notice that there are no shots of the turbines turning?
The commenters at the site worked the math on those turbines. I don't think this is the answer.

(29,798 posts)In general I'm not a proponent of small scale wind because it is too often overhyped to an uninformed public by less than ethical salespeople. Businesses don't usually fall into that group and are more likely to make an informed decision.
The analysis in the comments at the OP article are flawed in two ways:
1. Building surfaces (especially large buildings) can function to create site specific conditions that are radically different than the general wind conditions in the area. Without a knowledge of the way that particular building's design affects wind flow it isn't possible to make a determination of the performance of the system.
2. The average use by the commenter of an annual average wind speed grossly underestimates the production of the system. The power in wind doesn't increase linearly with the wind speed*. If you have wind speeds that are double the average you will be producing 8 times the amount produced at the average.
What this means is that the building's specific characteristics might produce a site with very favorable wind speeds that produce far more actual power than the method of analysis used by the commenter would show.
Anyone interested in a small scale wind turbine should monitor winds at the exact mounting location for at least a year before making a decision on the investment.
*"The formula for the power per m 2 in Watts = 0.5 * 1.225 * v^3 , where v is the wind speed in m/s."
