100% renewable energy to some may sound like nothing more than a pipe dream, but in reality, it already exists. As giant countries like China, North America and India continue to pump out never ending streams of greenhouse gas emissions into the atmosphere, small, low-elevation islands are at risk of serious damage from rising sea levels and more intense and frequent storms. But some islands refuse to surrender and are doing everything in their capacity to do their part, even if that means overhauling their electricity grid as a means to achieve 100% clean, renewable energy. Of course this transition does not only contribute towards a healthier planet, but also a lower fuel bill for the islands as it is expensive to purchase and receive diesel and other fuels by sea or air.

Tokelau

You may not have heard of the small island of Tokelau before, but its 1,500 inhabitants live on three atolls in the South Pacific where the maximum height above sea level is less than 17 feet. At the Durban Climate Conference in 2011, the Head of the Government of Tokelau, Foua Toloa, declared that his nation would be powered completely by renewable energy by 2012. By October of that year, Tokelau had fulfilled its goal.

Prior to the 2012 conversion to clean energy, the island was dependent on three diesel-powered generators (one on each atoll) that burned 200 liters of fuel a day and cost the country nearly $800,000 on an annual basis. Furthermore, Tokelauans only had access to electricity between 15-18 hours each day, hardly the recipe for progress and growth. Now, with their solar panels and batteries for storage when the sun isn’t shining, Tokelau can now produce 150% of its electrical need. Not only are carbon emissions and costs reduced, but energy is more accessible than ever before.

El Hierro

El Hierro is an island at the western edge of Spain’s Canary Islands that has forsaken fossil fuels in favor of the plentiful renewable energy sources that bless the island. With a dormant volcano, strong breezes and abundant sunshine to draw from, El Hierro uses water, wind and fire to power itself to self-sufficiency. Much larger than Tokelau, the island has more than 10,000 residents and formerly emitted some 18,200 tons of carbon dioxide each year. That is however, until El Hierro built wind turbines, photovoltaic  panels and hydroelectric sources to replace the need of polluting energy generation.

Samsø

The Danish island of Samsø was actually the first island in the world to become completely powered by renewable energy. In 1997, the island won a government sponsored competition to become a model renewable energy community and since then has added 21 wind turbines to fulfill the electricity needs of the approximately 4,000 residents. Of the 21 turbines that belong to the island twice the size of Manhattan, residents own a share in 20 of them. Soren Hermansen, one of the leading proponents of wind power in the area, addressed the critique that wind turbines are unsightly or noisy with the response, “If you own a share in a wind turbine it looks better, it sounds better. It sounds like money in the bank." It’s difficult to argue with that.

Transitioning to a 100% clean energy world is not only possible, it is inevitable. As Mr. Hermansen said, giving people a stake in creating clean energy will help accelerate its advancement. At Mosaic, we agree—the fastest way to grow the clean energy economy is to enable the most people to benefit from it. And our platform is making that possible. Thousands of people across the country are already earning 4-7% returns from 100% clean energy. We invite you to join us.
