There is no question that green power generation makes sense in many places. All islands around the world that do not have a carbon deposit to start with and have money to spare (Most definitely not Guam) The USA without doubt is going bankrupt almost entirely from decades of maintaining diesel warships that station on islands that have no means of energy production.
Then again, it is to Albertas benefit that they are maintaining a diesel fleet that consumes more than two Canada's combined. Pushing a 100,000 ton vehicle through the water consumes a ridiculous amount of fuel every second. The US went nuclear(electrical) on some larger ships because its literally too expensive to use carbon based fuel.

That being said, you can only go to around $300 million for a yacht because the ports that they dock at (and the Panama canal) are only "so" large. I mean, you can buy a million dollar car, but it still has to fit in a parking spot and take one lane on the highway.
For as long as the USA continues to ask for carbon, we actually have an obligation to keep pumping it to them. The USA is literally living on carbon, but Germany is diversifying away from it.
