Wind turbines 'only lasting for half as long as previously thought'...

Study of almost 3,000 turbines in Britain sheds doubt on manufacturers claims that they generate clean energy for up to 25 years

Wind farms have just half the useful lifespan which has been claimed, according to new research which found they start to wear out after just 12 years.

Loren, your comment, "My thought would be to take a suspect wind turbine and fully rig it out with sensors: accelerometers, vibration detectors and strain gauges, to really get a sense of what that overall system is facing in the real world and update or redesign based on that data (which very likely, they are already doing)."

Sounds like a good plan to me; let us hope research is already going on!

Would there be less stress on metals, bearings, resonance with other types of turbines if such large arms were not involved? Would these forms produce as much energy? Will risks to birds be different?
