The first generation of the Nissan Leaf was introduced in 2010, meaning that the batteries in the oldest Leafs (Leaves?) can now be ripe for picking. Together with the 4R Energy Corporation in Japan, Nissan has started a project that will provide the Japanese town of Namie with lighting, using solar panels and used Leaf batteries. Namie was significantly damaged by the tsunami that caused the Fukushima Daiichi nuclear disaster in 2011, and these streetlights are part of the town's ongoing rebuilding efforts.
The hook-shaped streetlights are completely standalone, meaning that they do not require a functioning main power grid to operate. While it's churning out more and more electric vehicles, Nissan recognizes that in the future there will be a lot of decommissioned electric car batteries, and if they can be used to get an entire town back from the darkness, that's a worthy second act.
