Interesting article on countries that produce the most solar energy

What are the differing ways in which total solar can or should be measured? 

Seems to me the measurements should be net residential rate, net commercial rate, and net industrial rate plus all production subsidies ($/MWh) and any fees attached to the bills. These are all hard numbers that can be straightforwardly obtained. No externality costs and similar qualitative costs that simply cannot be measured while being subject to all manner of mischief and abuse.

These figures provide a better picture of the economic of green energy because hidden impacts are better reflected in the bottom-line cost.

Correlations can be made relative to the mix of energy production resources and likely impact on net costs.

As a example, residential rates in California are about 3 times that of Kansas. The reason lies directly with a significantly higher penetration of green energy in California, while Kansas uses about 45% coal. Is this good or bad? Well if you are a rich liberal in California, you probably do not care because you can afford your electric bill. The poor and middle class might really start questioning what the Democratic Party is doing to their families.
