Tokelau, a South Pacific nation composed of several atolls can be powered entirely by solar energy, becoming the first nation that manages this.
A solar project with a total capacity of one megawatt was completed on the three atolls, this offering to 1,400 people an amount of 150% of the country's electricity. Tokelau Renewable Energy Project consists of 4,032 photovoltaic panels and 1,344 battery-powered generators using biodiesel from coconut, is one of the largest solar projects on Earth.
The project cost $ 7.5 million, a huge amount compared to the tiny nation's GDP, which is only 300,000 dolars. However, officials announced savings because they will not have to import gasoline and diesel to offset the high costs.
The original plan was for this project to generate only 93% of the power needed, the rest is produced by burning coconut oil. However, panels can generate 150% of the energy needs of those in Tokelau, so that coconut oil will only be used if cloudy days and in emergency situations.
The total capacity of the network was estimated at 1,400 Tokelau megawatt-hour, reducing by more than 950 tons of annual carbon dioxide emissions. Even if Tokelau does not contribute greatly to reduce the emissions of greenhouse gases, global warming is one acute discution for the inhabitants of atolls. Like other islands in the Pacific, Tokelau is threatened by rising ocean levels. Some parts of the island could survive rising waters, but the sources of drinking water have already begun to be contaminated with salt water due to rising sea levels.
Tokelau is not an independent country but a territory of New Zealand that comprises three coral atolls halfway between New Zealand and Hawaii. Nation area not exceeding 10 square kilometers and the population is only 1,400 people. The economy depends on trade with stamps and Internet sites - in 2012, one-sixth of GDP was due to sales related websites. Tk.
Following a small economy, Tokelau is dependent on financial assistance of New Zealand. Because Tokelau spent more than $ 800,000 annually on importation of fuel for generators, solar panels represents a significant step toward energy independence. This will allow the nation to become independent, being able to govern (except issues among foreign policy has to remain in charge of New Zealand).
Other countries obtain much of their energy from renewable sources are Paraguay ( which is characterized by the large number of hydroelectric dams ) and Iceland ( geothermal and hydroelectric ).
