First Renewable Energy Island

A tiny Spanish island with just 10,000 residents is about to do something amazing. El Hierro, the smallest of the Canary Islands, plans to completely sever ties with the traditional power grid and move entirely to renewable energy. The island plans to become completely self sufficient next month when its 11.5 megawatt wind farm kicks into gear. El Hierro already has a water turbine that generates electricity, and the added wind power will enable the island to go totally off-grid.

The island actually generates enough power for its residential needs with just the water turbines, but the wind power allows El Hierro to have a little extra power, which will be used to pump fresh water from near the harbor on the island to a reservoir in a volcanic crater 2,300-feet above the sea. When there is not enough wind for electricity needs, that water will be released to feed down into the water turbines to generate more energy, so the island will always have enough power to keep things running.

Imagine if more islands are able to farm such energy. Over time and trials of projects like these, we will learn of ways to make building out wind turbines to be more efficient and effective. In a closed environment such as islands this could be rather optimal.
