A wire rope transmission was considerably more efficient than electricity up to distances of about 5 km (3 miles).
(...)
From this he calculated that the efficiency of a wire rope transmission was 97% for a single span (two pulley stations), 95% for two spans (three pulley stations), 93% for three spans (four pulley stations), and 90% for five spans (six pulley stations). For nine spans (ten pulley stations), efficiency went down to 85%.

A wire rope transmission from 1860 is still more efficient than a moden electric transmission up to a distance of at least 1 km.
