  • John D. Rockefeller's Standard Oil dominated refining
  • Kerosene became primary lighting fuel before electricity
  • Oil-based lubricants improved machine efficiency
  • Later, gasoline powered internal combustion engines
  • By 1900, oil became central to American industry

Electrical Revolution

Electricity changed nearly every aspect of American life. Edison's light bulb and power stations brought electric lighting to cities, while Tesla and Westinghouse's alternating current system allowed electricity to travel long distances. Electric power transformed factories, transportation, and eventually homes.

• Electric Lighting Innovation:
  • Thomas Edison invented practical incandescent light bulb (1879)
  • Built first electric power station in Manhattan (1882)
  • Edison's direct current (DC) system had limited range
  • Electric lighting replaced gas lamps in cities
  • Extended productive hours in factories and businesses
  • Created safer working conditions than gas lighting
• Alternating Current Development:
  • Nikola Tesla and George Westinghouse developed AC system
  • AC could transmit electricity over much greater distances
  • Resolved "War of Currents" with Edison's DC system
  • Made widespread electrical distribution possible
  • Allowed factories to locate away from water power sources
  • General Electric and Westinghouse became industry leaders
• Electric Power Applications:
  • Electric motors transformed factory production
  • Electric streetcars revolutionized urban transportation
  • Elevators made taller buildings practical
  • Early electric appliances began appearing in homes
  • Electric power became core infrastructure for modern cities
