Wind turbine blades with twisted and tapered tips

A blade 10 for a wind turbine 2 includes a total backward twist of between approximately 6 degrees and approximately 15 degrees between an outer approximately 1 percent to approximately 10 percent of a rotor radius of the blade; and a total normalized chord change of between approximately one percen...
