Dumb question: is there a limit to how much energy we can capture? I'm imagining a wind gust blowing east to west across a city filled wind turbines. By the time the gust reaches the west end of the city, has most of its energy been captured or otherwise dissipated?

Contrasting that with solar, where any surface area receiving direct sunlight doesn't prevent other adjacent areas from also capturing solar.

So there's the hobbyist side of it, but I guess it's not totally clear why that matters to the people talking about the world's power mix.

But as I write that, I guess it becomes more clear to me that a personal interest in installing the technology makes one pay more attention to it elsewhere, and promote more conversations about it that get others involved.
