The concern was for the integrity of the building structure in high wind conditions. Estimates at the time suggested that if the mass damper was disabled by a power failure, the building could be toppled by a 70-mile-per-hour (110 km/h) quartering wind, with possibly many people killed as a result.
Many wind power companies work with local communities to reduce environmental and other concerns associated with particular wind farms. [109] [110] [111] Appropriate government consultation, planning and approval procedures also help to minimize environmental risks. [112] [113] [114] Some people may still object to wind farms. [115]
The Vattenfall utility company study found Hydroelectric, nuclear stations and wind turbines to have far less greenhouse emissions than other sources studied.. A typical study of a wind farm's Life cycle assessment, when not connected to the electric grid, usually results in similar findings as the following 2006 analysis of 3 installations in the US Midwest, where the carbon dioxide (CO 2 ...

In September 2014, for example, Renewable Energy World suggested "With its claim of 28,000 dead birds from Ivanpah, the Associated Press syndicated a story on every front page in America, spreading alarm about concentrated solar power (CSP) plants, which was not grounded in facts, but on one opponent's speculation."

Wind speeds can vary considerably across a wind farm site if the terrain is complex (hilly) or there are changes in roughness (the height of vegetation or buildings). Wind flow modeling software, based on either the traditional WAsP linear approach or the newer CFD approach, is used to calculate these variations in wind speed.
The Tipton Catastrophe or Dudley Port explosion was a 1922 munitions explosion in the South Staffordshire town of Tipton, [a] England, in which 19 teenaged girls, ...
