1. Tokelau Archipelago, New Zealand: It is the first territory in the world that generates 100% of its electricity from solar panels. In its 125 islets, 4,000 panels are located for the supply of its 1,500 inhabitants. The highest point of these islands is only 5 meters above sea level, so the project was developed with some "fears as this territory could suffer because of climate change due to the rise in the level of the sea ??"expressed the Ministry of Foreign Affairs and Trade.
