Workmen burying Edison DC power lines under the streets in New York City in 1882. This costly practice played to Edison's favor in public perceptions after several deaths were caused by overhead high-voltage AC lines.

Berlin, 1884. With double the brilliance of gaslight, arc lamps were in high demand for stores and public areas. Arc lighting circuits used up to thousands of volts with arc lamps connected in series.

Prior to electricity, there had already existed multiple forms of power transmission, though they remained largely inefficient and expensive. These transmission lines operated perhaps within more of the physical realm of movement and power, utilizing telodynamics, pneumatics, and hydraulics. Electricity emerged as a much more cost-effective alternative, though the new system still encountered technical difficulties. There existed a particular struggle between AC and DC methods of transmitting electricity. Proponents of DC argued for safety, while others argued for convenience. Although there are doubts and fears from the general public, AC ultimately defeated DC due to its ability to travel long distances. Early electricity primarily supported street lights, electric motors in factories, power for streetcars, and lights in homes. Transmission lines were primarily made of copper and rion. Generators first commonly emerged as dynamos but then transitioned to alternators using hydroelectric and coal.
