Photovoltaic Capacity.

The article is interesting enough in itself, but I of course gravitated to the first map, looking for patterns.     

The Southwest, in contrast, shows concentrations in the sunniest areas, but not in other parts of the same states, suggesting that those states do not offer solar incentives.  Where the sun is solar incentive enough, no additional help is deemed necessary.  Georgia, and especially Florida, are more ambiguous. Also, there’s a blip on Virginia’s Eastern Shore and maybe in the Dismal Swamp region that deserves explanation.  Massachusetts, Vermont, Minnesota, New Jersey, and North Carolina are clearly doing something to encourage solar, as they show concentrations that end at their borders.
