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
Renewable Energy Needs Huge Mineral Supply
Renewable Energy Needs Huge Mineral Supply November 2nd, 2013 | Tim Radford, Climate News Network | Climate Central LONDON – Humankind could be about to exchange one kind of energy crisis for another. The switch from the finite store of fossil fuels to renewable sources could involve a huge additional demand for the world’s equally finite … Continue reading Renewable Energy Needs Huge Mineral Supply

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.
Wind-turbine gearboxes chance of one or more of the 20 to 25 bearings failing within seven years is 37%.
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?
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 A Major Environmental Concern
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
