It’s unofficially official. Japan has emerged as the only country where electric-car charging points (40,000) outnumber the gas stations (34,000). The announcement was not made by the government but by Nissan Motor Co, the country’s second-biggest car maker, which produces the battery-powered Leaf model that runs 135 km on a single charge. But Nissan would be keen to see the statistics get replicated in the US. As the biggest market for Leaf — 72,322 vehicles sold since launch — the US has just 9,000 charging stations.
