Island Nation Now Runs Entirely On Solar Power

Far to the north of the coast of New Zealand, the teeny tiny island nation of Tokelau just finished making a full switch to solar power—a renewable investment that will help the nation’s roughly 1,400 people kick their $825,000 per year reliance on imported diesel.
Tokelau is a dependent territory of New Zealand, a total of 12 square kilometers of land stretched over three islands—Atafu, Nukunonu, and Fakaofo—that lie, at their highest point, just 16 feet above sea level. On top of the economic incentive of no longer needing to import so much fuel just to keep the lights on, says AlertNet’s Peter Madden, the switch is “a commitment to environmental sustainability on the frontier of climate change.”
Like other low-lying islands, “Tokelau is particularly vulnerable to climate change and will be among the first to feel its effects” as melting glacier ice and other shifts cause the sea level to rise.
Tokelau’s new solar-powered grid was built up over three months and consists of “4,032 photovoltaic panels and 1,344 batteries with generators running on biofuel derived from coconuts,” says UPI.com. The one-megawatt installation should be able to provide around 150% of Tokelau’s total electricity demand. By comparison, the same plant would power roughly 200 homes in the United States.

Its great they went all solar, but they should have done a mix of solar and wind.
if they had set up 20 small wind turbines, they would have had a much broader energy spectrum and they would have less need for battery.

Solar and coconut bio oil with battery back up is a good plan. Maybe they don’t have much wind. Each area is different and this must work for them.
Their old cost was $589 a person /year or $11.32 month. Not too bad compared to developed countries at an average $150 a month.
