12-21-2017 | Natural Resources Canada The operation of wind turbines in a cold climate such as Canada’s involves additional challenges not present in warmer locations: Accumulation of ice on wind turbine blades resulting in reduced power output and increased rotor loads; Cold weather shutdown to prevent equipment failure; and Limited or reduced access for maintenance … Continue reading Wind Energy in Cold Climates
Another One Bites the Dust: Wisconsin Wind Farm Decommissioned After Just 20 Years
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

FIRE RISK IN WIND TURBINES
The fires in wind turbines not only lead to a loss of business continuity and a negative impact on the company’s reputation but also, most importantly, are a critical safety issue. Possibly harmful debris can be drifted by the wind in the event if a fire and there is also a significant risk to human lives. When turbines are under erection, commissioning maintenance and repair, escape routes for operators are often long and vertical. Three out of six incidents involve a human presence in the nacelle; hence, a fire becomes a safety concern
Calculate the Sweep Area of Turbine Blades.
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.
Higher Breakdown Risks and Maintenance Required for Newer Larger Wind Turbines.
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.
FIRE SAFETY IN WIND TURBINES
Possible ignition sources include lightning strikes, overheating, surface ignition, and electrical failure. Combustible materials inside a wind turbine include the composite materials of the blades, the interior surfaces and linings of a nacelle, and the main shaft of the turbine itself. Furthermore, there are flammable liquids in various parts of the nacelle, including the gear box, hydraulic system, oil pumps, mechanical brake, and generator.
The size of 500 foot turbines is hard to grasp.
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.
How big is a wind turbine?
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?
