This article discusses the limited longevity of older turbines, statistics are showing that the newer larger turbines have an even shorter average lifespan between 7 and 15 years. Another One Bites the Dust: Wisconsin Wind Farm Decommissioned After Just 20 Years November 21, 2018 | Isaac Orr in | American Experiment An industrial wind facility … Continue reading Another One Bites the Dust: Wisconsin Wind Farm Decommissioned After Just 20 Years
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.
Newer windfarms require more than double the amount of maintenance than older ones, according to an independent inspection firm. September 26, 2018 | David McPhee | Energy Voice Windfarms under five years of age require on average seven repairs per turbine in contrast to those older than that period only needing 2.2 repairs. A report … Continue reading Higher Breakdown Risks and Maintenance Required for Newer Larger Wind Turbines.
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.
Industrial wind turbines are a lot bigger than ones you might see in a schoolyard or behind someone’s house. As wind energy has expanded into less and less ideal wind areas they have gotten larger, and most being installed are ranging from 400 to as tall as 700 feet. RES has stated that they are installing … Continue reading How big is a wind turbine?
How much energy do wind turbines produce? Every wind turbine has a range of wind speeds, typically around 30 to 55 mph, in which it will produce at its rated, or maximum, capacity. At slower wind speeds, the production falls off dramatically. If the wind speed decreases by half, power production decreases by a factor … Continue reading Wind Energy production as fickle as – The wind.
We have not posted as much on turbine noise, as it will have an effect primarily on the wildlife, and anyone in the the area, hiking, or hunting. Listen here: The sales pitch newer industrial turbines are only as loud as a refrigerator. What they do not add is that it sounds like a refrigerator … Continue reading Sales Pitch: Industrial Turbines are Quiet – FALSE
