THE Canarian island of La Gomera is aiming to be powered 100% by 'green' energy sources within 12 years, slashing its power costs by 37%.
La Gomera, just off the coast of Tenerife, will be the second island in the region to try to go completely 'renewable' after El Hierro attempted it between 2014 and 2016.
The latter survived for months on wind energy alone and, in 2016, covered 39% of its electricity needs using wind farms – then, in January and February this year, had all 10,700 of its inhabitants supplied entirely by renewable sources for 18 consecutive days.
But La Gomera's plans are far more ambitious – the westernmost island in the Canaries currently depends upon fossil fuel for 99% of its power needs and, aside from a handful of solar panels owned by private individuals, has just two wind generators of 0.4 megawatts (MW) of power.
Despite La Gomera being famous Europe-wide for its extensive forests, being the home of the Garajonay National Park and a pioneer in 'eco-tourism' dating back over 20 years, its obvious potential for powering itself through entirely renewable sources is wasted more than anywhere else in the Canary Islands.
The regional government wants to turn La Gomera into another Iceland by 2030, mirroring Europe's northernmost country's 100% green energy supply.
By then, it aims to have enough wind farms to create 8MW of power, sufficient solar panels to generate 5MW, and for 20% of the island's cars to be electrically-powered.
The overall objective is for the island, whose population is twice that of El Hierro and which has tourist resorts with capacity for 800 visitors, to be entirely fossil-fuel free and rely on green energy for its electricity, heating and transport – lorries and buses will be electric or hydrogen-powered.
Hydrogen generators, water pumps and storage systems are being analysed as back-up for when there is insufficient wind and sun to cover the whole island's energy needs.
The considerable cost of this ambitious project would be offset within around seven to 12 years thanks to lower production expenses, meaning that by 2042 La Gomera will start to see a return on its investment.
