I'm all for efficiency and green-er energy, but I think we should find a balance between an effective solution and an aesthetically acceptable one.
So solar panels don't necessarily have to be large rectangles floating over the existing roof. Especially in a new build, you'd integrate them into the roof.
There's also the mere-exposure effect that will play out, people tend to develop a liking to things just because they are familiar with them.
When you live next to them, you'll find out that they're surprisingly loud, and some people start getting terribly annoyed when there's something constantly moving and catching their attention (in cases where they are visible from your desk, for example).
"The needs of the many outweigh the needs of the few, or the one."
Global warming affects every human on Earth, and even those not yet born. It is our duty as the substantially more privileged denizens of the first world to take actions to combat it, especially in easy ways such as this legislation.
Never mind the aesthetic judgement–would you even see them in the course of a normal day? I just had to use google earth to find out the color of my roof.
Maybe for a single-story house, yes, you could probably see them (when you're outside, during the day). So maybe this serves as motivation for more two-story development? That would have the added benefit of reducing urban sprawl–imagine cutting your commute in half!
Other than that, I'd say that yes, this seems to be one of those situations where the tradeoff seems justified, especially in Florida, which will be the first state below sea level if humanity can't get its act together.
