If you feel insulted when I point out the life span is roughly 4 times as long as you estimate
Hmm? I didn't refer to you pointing out a lifespan that is four times as an insult. I was referring to your decision to write "STUPID IDIOT" in all caps.
The point was to make an overestimate of the amount of material produced. Therefore, a deliberately underestimate of life span is used
Yes. And that was pretty clear.
So apparently you think someone is a "STUPID IDIOT" for rounding more generously than you would? That's an interesting viewpoint. But maybe we should discuss why I did decide to use 10 years rather than 40 (which I agree is more typical). Repowering is a thing https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwwindea.org%2Frepowering-an-efficient-tool-to-boost-wind-power where turbines are replaced in part or in whole well before the end of their lifespan. And while this is only a small fraction of all turbines, it does occur. The sort of people who are apparently ideologically committed to being against wind power like to point this out especially when there are systems which are being replaced in around 12 to 15 years. So by using 10 years, it preempted any claim of that sort.
As for the rest of your comment: I'm mostly in agreement and would only take issue with your last two sentences. But the precise claim in question is about the amount taking up by wind turbines going into trash. And you are in agreement apparently with the OP about the blades, which are large, heavy and a major component, and are not currently recycled. (Although we're working on getting better at that). So it certainly then isn't a "myth" that they cause trash and garbage. The amount really does matter. The amount is small, but it isn't a myth.
