TJ,

The story mentions that the latest units from Siemens do not have a gearbox:

" The turbines are completely gearless, "

So, seems like they have figured out a way to eliminate that weak-point.

As wind generated power increases its prevalence, we will see some diminishing returns. It is only so long that subsidies can pick up the slack before leaving a huge gap in the money stream.

Do taxpayers pay those subsides? Yes.

We end up paying more than reported for that green generated power. Keep that in mind.

Storage of non-heat alternative energy is definitely a problem. However, mixing technologies can also be done to "load balance" uneven energy input.
