Vestas Red Turbine Blades to Be Tested for Bird Safety at Hollandse Kust West VI Wind Farm
http://offshoreWIND.biz A new trial will be launched at Ecowende’s Hollandse Kust West VI offshore wind farm in the Netherlands to test whether red blades improve visibility for birds and reduce collision risks. Vestas is supplying one red-coated blade for each of the seven turbines involved, replacing the standard grey design.

The objective of having a single blade in a different colour is to create a smear, which is expected to be more visible to birds. A lot is still unknown about this effect, including which colours and patterns work best, according to Ecowende, a joint venture of Shell, Eneco, and Chubu.
