El Hierro, the smallest of Spain’s Canary Islands, has become a global leader in sustainability through its ambitious energy and environmental initiatives. The island is powered almost entirely by renewable energy, with wind and hydroelectric power supplying 100% of its electricity needs. In 2014, El Hierro completed the installation of a pioneering wind-hydro hybrid system, known as the Gorona del Viento project, which stores excess wind energy in hydroelectric reservoirs to ensure a constant power supply. This achievement has made El Hierro a symbol of energy independence and a model for small islands around the world.
Beyond energy, El Hierro is also advancing sustainable agriculture, waste management, and water conservation. The island encourages local, organic farming and has implemented water recycling programs to cope with its limited resources. With a focus on eco-tourism, El Hierro attracts visitors interested in its natural beauty and sustainability practices. By balancing environmental protection with economic development, El Hierro demonstrates how small islands can transition to a greener, more sustainable future while fostering a thriving local economy.
