"Wind turbines catching fire" isn't a bug.  It's a feature.  You, yourself, go on to state: "three birds could have been barbecued" which means those windmills provided the local population with a free meal thus enhancing their daily nutritional intake.

We need more windmills frying birds for the greater benefit of All Mankind.

In germany I doubt anything bad can happen with a fire.

But with such an issue on a turbine in an isolated area in the south of Europe in dry but windy summer with plenty of dry vegetation waiting to take fire that's another story.

Any industrial electric installation has such risks of course, I don't think wind turbine have additional risks (except for there remote/top of hill typical location)  but I didn't know these could take fire either.
