Green energy

There is a place on Earth that is 100% powered by renewable energy sources – the three atolls of Tokelau.
Previously the island country was powered by shipping in thousands of barrels of diesel fuel. According to PowerSmart, the New Zealand based company that installed the Tokelau Renewable Energy Project, diesel generators were burning around 200 liters of fuel daily on each atoll, meaning more than 2,000 barrels of diesel were used to generate electricity in Tokelau each year.
