JOHN ADDISON – Electric car sales triple in the U.S. each year – 20,000 in 2011, 60,000 or more in 2012, 180,000 or more in 2013. Accenture forecasts 1.5 million electric vehicles in the United States by 2015. Over 10 million electric vehicles are possible by 2020, especially if oil prices rise as battery prices fall. Single electric utilities have scenarios for charging over one million electric vehicles in their own service area by 2020.
