A blade on a wind turbine in Sheffield has broken in strong winds for the second time in 15 months.
Well, hey, mechanical things break, just what mechanical things do.
A Sheffield University spokeswoman said : \”It is not clear why this happened and an investigation is being carried out by the wind turbine manufacturers.
\”We are clearly concerned and have requested that the wind turbines are not put back into service until the suppliers and independent consultants have carried out their investigations and can confirm the safety of the equipment.\”
But it\’s not really the safety that\’s the problem here. The already very dodgy economics of wind power depend on hte fact that once you\’ve built them the energy is for free. But if you\’ve got huge and continual maintenance bills, then the energy ain\’t for free, making the economics even more absurd than they were.
You out there of course know more collectively than I do on my lonsesome this side of the blog software. So what are the operating cost assumptions in the wind power caluclations and what are the actual operating costs compared to those assumptions?
