America in the Central Powers and British coal control

What if America joined the Central Powers in 1890 and remained aligned with Germany through the 1914 war declaration?

Britain would focus on Canada, Atlantic security, and its leverage over global coal supplies, while the Royal Navy might build more fast capital ships to answer American naval power.

An American alignment with Germany from 1890 would make the Canadian border and Atlantic security greater British concerns. The proposed earlier Anglo-French intervention for the Confederacy is set aside because breaking the Union blockade would change the Civil War too extensively to assume the same later United States. British control of overseas coaling and coal transport could constrain fleet demonstrations such as the Great White Fleet, since the United States lacked a comparable global support network. The Russian voyage toward Tsushima illustrates how dependence on overseas coal could narrow a fleet's route and timing. A possible British response is to build more Tiger-style battlecruisers for rapid Atlantic deployment, though the American construction program would affect that choice.
