The battle you are referring to is actually called the Battle of the Ironclads. In this battle, it was the Merrimac (from the Confederacy) versus the USS Monitor (from the Union).

The access to power was the direct result of the REA for farmers.
REA is the Rural Electrification Act (1936).
The REA was part of a program from President Frankling Delano Roosevelt designed to overcome the effects of the Depression years.
