Norway has a long-standing record of having the highest plug-in electric car market share, which so far is still way (way, way) out of reach for any other country in the world to come close to assaulting.
New plug-in passenger car registrations in Norway – April 2017
According to the DOE’s Office of Energy Efficiency & Renewable Energy, nearly one out of every four vehicles(23.5%) sold in Norway for 2016 was a plug-in (all-electric or plug-in hybrid).
And if we exclude light commercial vehicles, the market share stands at nearly 29%!
For comparison, Netherlands barely exceeded 5% in 2nd place.
"Norway had the highest plug-in electric vehicle (PEV) market penetration of European countries – nearly one of every four vehicles sold in Norway in 2016 was a PEV (23.5%).
Although 17.3% of all European PEV sales were in the United Kingdom, the PEV market penetration was only 1.3% due to the relative size of the market. The Netherlands had the second highest market penetration rate of PEVs at 5.1%, securing 10.1% of the total European PEV market. For comparison purposes, the United States PEV market penetration in 2016 was 0.9%."
