Wind turbine payback period claimed to be within 8 months

Jun 16, 2014 · I interpret: at a 22% faceplate efficiency (Euro experience) creation energy return is 3.5 to 5.0 years (5 X 6-12 months). Now you have 15.0 to 16.5 years of operating life. At 22% operation, the operating life will be greater than 16 years but it will not be 5 X: things machinery standing idle still age
