  • In the early 1900s, some North Dakota residents began using wind power to produce electricity.
    • Wind chargers generated electricity for small electrical devices in rural (country) homes.
      • Generating electricity from wind chargers had drawbacks.
        • Only very small devices could be powered by wind chargers.
        • A battery back-up was needed when the wind was not blowing.
  • In the 1940s, electricity was brought to North Dakota farms by Rural Electric Cooperatives (RECs).  
    • The RECs built power lines to carry electricity to the farms.
      • By 1954, almost all of the farms in North Dakota had electricity brought by the RECs.
      • The small wind chargers were no longer needed.
