> So what are some of the best talking points to "sell" solar and wind to the unconvinced?

Increasing utility energy prices worked for me. I wasn't anti-solar, but it didn't seem worthwhile for me. When the utility price doubled over three years (or just about), the math makes sense now. I'm not looking for solar to acheive grid independence though, I already have a whole house generator for that, because utility power is two nines reliable around here.
