If electric cars are to have a positive environmental impact on the world, the batteries of old electric models must not be wasted, but rather, they must be repurposed for other uses. One shining example of this can be found in Naime, Japan—a city that was abandoned after the Fukushima nuclear disaster. There, Nissan is using old Leaf batteries to power streetlights. Called The Light Reborn, it uses a solar panel that charges up the battery, which can then power the LED at night with no external connection required.
