The thing you neglect to acknowledge is that Puerto Rico is a colony of the U.S. This has a number of unfortunate consequences one of which is that they do not have the financial powers of a state. If they did or if they choose to become a state then the equation in terms of finance, political power etc. changes. The other issue is choices. We have become addicted to electricity. That addiction hinges on cheap power, which in reality isn’t because of hidden costs, unacknowledged costs i.e. environmental impact. Were all of these factors included in the calculations power would be a substantially more expensive proposition and its use more circumspect.
