IWTs–cause climate change; don’t respect setbacks

Wind farms can cause climate change, finds new study – Telegraph

Research overseen by SUNY Albany professor Liming Zhou and just published in the journal Nature indicates

a “significant warming trend” of up to 0.72C (1.37F) per decade, particularly at night-time, over wind farms relative to near-by non-wind-farm regions.

The team studied satellite data showing land surface temperature in west-central Texas.

“The spatial pattern of the warming resembles the geographic distribution of wind turbines and the year-to-year land surface temperature over wind farms shows a persistent upward trend from 2003 to 2011, consistent with the increasing number of operational wind turbines with time,”  said Prof Zhou.

Louise Gray, Environmental Correspondent, reported this story for the UK’s The Telegraph.

Damaged Turbine Suspends Wind Energy Production

The 55 turbines of the Timber II project in Ohio (on the Indiana state line) were shut down following an incident with one of the turbines. Blades came apart, raining debris on the farm fields below the turbine. (And according to an Julie Johnson, speaking on Wind Wise Radio April 29th, pieces of the broken turbine blades traveled over 1300 feet away from the turbine.  Incidentally Ohio has a set-back of 700 feet).
Reporters Rachel Martin and Megan Trent tell the story:

Around 12:45 Tuesday afternoon, two blades on a turbine were damaged so severely that debris was sent raining down on the field below. No one was injured.

The owners, EDP Renewables, say while the investigation into what damaged the blades is ongoing, at this point it doesn’t appear that strong winds were a factor.

A spokesperson for EDP tells Indiana’s NewsCenter that all 55 of the wind farm’s turbines were immediately shut down following the incident. Some were turned back on Wednesday as part of the investigation, but officials say it’s unclear how long that investigation will take.
