El Hierro Case Study

  • Starting to develop energy independence

    Starting to develop energy independence
    Today, El Hierro is no longer at the furthest edge of Earth’s landmass; instead, it is at the cutting edge of human attempts to create communities that rely entirely on sustainable, clean energy. Since 1996, El Hierro has worked steadily at becoming the first energy-independent island in the world that is powered only by renewable energy sources.
  • El Hierro consortium was formed

    El Hierro consortium was formed
    The Gorona del Viento El Hierro consortium was formed in 1996. It included islanders, faculty and students from the Canary Islands Institute of Technology, consultants from the Spanish utility company Endesa, and representatives of the Spanish government.

    All participants were focused on shifting the island’s energy source from diesel-powered generators to a wind and water turbine farm that would use no fossil fuels and emit no CO2.
  • 60% of the island became protected

    In August 2014, the Spanish Minister of Industry gave the multinational oil company Repsol permission to drill three exploratory deep-water perforations in the ocean seabed near the Canary Islands. The Canary Islands is one of the largest marine areas in Europe and is among the most spectacular areas on Earth for marine biodiversity.
