Great question. I believe the need for coaling stations was a driving force in Imperialism. Here's why. The US was converting its commercial fleet from sailing vessels to steam (coal fired) vessels at the end of the 19th Century (oil fired steam would come a few decades later.) Given that a ton of coal takes up 40 cubic feet and that one ton of coal would drive a steam vessel about 10 miles you can calculate the amount of coal it would take to get to Hawaii or Asia. If you assume that the average steam vessel was less than 300 feet in length with a beam of 50 feet and depth of forty feet you can estimate a percentage of space required for these trips. (don't forget to deduct space for crew quarters, the steam engines and other shipboard necessities) If you are a business person you also realize that if you can reduce this space for fuel to a bare minimum with lots of coaling stations, you can make much more profit for each trip. US imperialism was based on trade therefore we were highly motivated to increase profit for our China trade thus the need for more and more territory on which to locate coaling stations. Any other rationale for territorial expansion is nowhere near as compelling in my view.
Because they liked coal
Coaling Stations
Hawaii was an ideal spot for coaling stations and navel bases for ships traveling to and from Asia.
Imperialism.
The main coaling and supply stations for Union ships participating in the blockade against the South were:1. Beaufort, North Carolina 2. Port Royal, South Carolina 3. Pensacola, FloridaThere were others, however, the three mentioned handled most of the Union's traffic.
Guantanamo Bay
