Swept Area and Rated Power The power output of a wind turbine is directly related to the area swept by the blades. The larger the diameter of its blades, the more power it is capable of extracting from the wind. Rotor Diameter – This number is listed on most wind turbine spec sheets. It is simply … Continue reading Calculate the Sweep Area of Turbine Blades.
This is a 'wind-friendly' article. The calculations about failure support what we've researched about turbine durability- "... nearly all gearboxes in a wind farm are likely to fail within 20 years. This may seem shocking, but it is a reality in the field. Many wind operators will attest that most gearboxes have been changed or … Continue reading Wind-turbine gearboxes chance of one or more of the 20 to 25 bearings failing within seven years is 37%.
Can Offshore Wind Turbines Succeed in the Great Lakes? Ice jams and bird and bat deaths will determine the answer August 14, 2018 | Daniel McGraw | scientificamerican.com Aside from a small pilot program along the coast of Finland, offshore wind turbines have not been placed in waters that freeze during winter. Moving ice can act … Continue reading Can Offshore Wind Turbines Succeed in the Great Lakes?
DISPOSAL OF WIND TURBINES PROVING TO BE A MAJOR ENVIRONMENTAL CONCERN 07/15/2018 Jason Hopkins | Energy Investigator Thousands of aging wind turbines will eventually need to be decommissioned, but the disposal of this “green” technology could prove to be a dirty job for environmental regulators. Besides a host of problems that occur during a wind turbine’s … Continue reading Disposal Of Wind Turbines A Major Environmental Concern

There seem to be some who just do not grasp how large these 500 foot turbines are. They are as tall as a 50 story building. Many that people have driven by in good wind areas are 200 to 300 feet tall. As the developers go to marginal wind areas they need taller turbines. More … Continue reading The size of 500 foot turbines is hard to grasp.
