El Hierra

Within the next year, El Hierro, the smallest island of the Canary Islands, hopes to become completely energy independent.

After 10 years of planning, the infrastructure is being put in place to transform the island (with its population of 10,000 inhabitants) into a fully self-sufficient zone. There will be no back-up power connection to other islands or the mainland.

A variety of renewable energy systems are being used, with an emphasis on wind and solar. They also plan to implement hydrogen cars and ban oil completely from the island.
