A small island in the Atlantic is showing how energy storage can be used to help run on 100% renewable energy.
To get to El Hierro, in the southwest tip of the Canary Islands, you first need to fly to the provincial capital of Santa Cruz, in Tenerife, halfway along the island chain. There, a surprising sight currently greets visitors.
Alongside the cargo boats and cruise ships in the town’s busy port lie three hulking drill rigs.
The massive structures await the start of an oil prospection project green-lighted by Spain’s Minister for Energy, Trade and Tourism, Jose Manuel Soria, in the waters between Morocco and Fuerteventura in the eastern Canaries.
Soria’s steamroller approval of the project, with an OK being granted in principle even before the closing date for objections, has angered Canary Islanders.
The potential for oil extraction
They see the potential for offshore oil extraction as a threat to tourism, the main source of income for the islands.
“They’re probably here because if they were in Fuerteventura people would set fire to them,” says Olivier Bello, who works at Tenerife’s La Laguna University, nodding towards the drill rigs.
The islanders have good reason to feel concerned. After all, in El Hierro, less than 30 minutes flight time by prop plane from Santa Cruz, they are showing how there could be another, more sustainable energy economy.
