California is often touted as the capital of electric cars, but a new report indicates that title belongs to Norway. In the month of September, the Scandinavian country reported 6,524 new registrations of plug-in electric cars, taking a record 48.4 percent of the market share. The big surprise however is that the new record was most influenced by deliveries of more than 2,000 Tesla cars. With electric cars on the rise, it may not be such a surprise that the average CO2 emissions in Norway have also hit a record low.
