What was once regarded as technically impossible and the stuff of science fiction is slowly becoming reality. The westernmost of the Canary Islands considered the end of the known world until the voyage of Christopher Columbus proved otherwise is now set to become the first in the world to have all its energy needs covered from renewable sources. La Gorona del Viento (translated roughly as the Wind Stable) is an ingenious project to harness the locally constant winds to operate a hydro-electric station that will provide a permanent supply of energy to the 7,000 inhabitants of the island.
Participants in the first fleet of the Barbados 50 Odyssey were treated by the Tourism Board of El Hierro to a tour of the island that included a visit to the various sites of the Gorona del Viento project.
The basic concept of the project is to use the prevailing NE winds to produce electricity with five wind turbines (maximum capacity 11.1 MW) either to supply electricity directly for domestic use (estimated at 7.4 MW per day) or to drive a bank of pumps that will lift the water from a lower reservoir 700 metres to the higher reservoir.
When either the wind turbines do not produce enough electricity or the consumption is too high, the difference is made up by producing electricity with a bank of water turbines. On three separate occasions this year, the project covered all island’s needs, once for as long as 72 hours.
The rest of the tour was taken up by stopping at some of El Hierro’s main attractions.
The unanimous decision among the sailors, who perhaps more than anyone else, are well aware of the utmost importance of using renewable sources of energy, was that El Hierro’s project is a remarkable model for the rest of the world… to be hopefully repeated soon on a much larger scale.
