I've never thought of a golf carts or any small recreational vehicle as "green" in any sense. its just a fun travel toy when used off the golf course. maybe its practical for some folks. but it ain't green by any means.
y'all should write your legislative rep, and push for repeal of the LSV statute if you think that's the case. Florida's LSV statute is viewed by me as progressive, but you have all pointed out a couple exceptions to the rule of them being green... like the point about coal fueled electical capacity in Florida. I agree coal fired needs to go too, and Florida is a follower in that regard. 30% of Florida's electricity is coal fired, 45% nat gas, 13 percent nuclear, and the remainder from other sources. 30% is unacceptably high.
This (the LSV) statute was debated on this very issue in the FLorida legislature, meaningful debate. The evidence the scientists brought in was overwhelmingly supportive that LSV's were "better" .... from a carbon perspective... but your point stands.
I implore you to follow your heart, and go to Tallahassee and push for repeal the LSV statute...make Walton County proud.
