Has the time come for electric vehicles? John Manley Managing Director: Nissan New Zealand
The electric car La Jamais Contente
The advantages of the early electric car: They did not have the vibration, smell, and noise associated with gasoline cars. Changing gears on gasoline cars was the most difficult part of driving, while electric vehicles did not require gear changes. The only good roads of the period were in town, causing most travel to be local commuting, a perfect situation for electric vehicles, since their range was limited. The electric vehicle was the preferred choice of many because it did not require the manual effort to start, as with the hand crank on gasoline vehicles, and there was no wrestling with a gear shifter.
The decline of the early electric car By the 1920s, America had a better system of roads that now connected cities, bringing with it the need for longer-range vehicles. The discovery of Texas crude oil reduced the price of gasoline so that it was affordable to the average consumer. The invention of the electric starter by in 1912 eliminated the need for the hand crank. The initiation of mass production of internal combustion engine vehicles by Henry Ford made these vehicles widely available and affordable in the $500 to $1,000 price range. By contrast, the price of the less efficiently produced electric vehicles continued to rise. In 1912, an electric roadster sold for $1,750, while a gasoline car sold for $650.

US Pentagon report on Peak Oil: The US military has warned that surplus oil production capacity could disappear within two years and there could be serious shortages by 2015 with a significant economic and political impact. "By 2012, surplus oil production capacity could entirely disappear, and as early as 2015, the shortfall in output could reach nearly 10 million barrels per day," says the report, which has a foreword by a senior commander, General James N Mattis.

PERSONAL TRANSPORT IN NZ TODAY Personal transport in New Zealand today • 91% of adult New Zealanders own cars • Over 50% of households have 2 or more vehicles • 1 in 3 New Zealanders see their only reason to own a vehicle is to get from A to B • Approximately 2/3rds of New Zealanders travel to work by car. • Public transport is poorly supported. • Urban owners have a mean daily travelling distance of less than 40 kilometers. • Rural owners have a mean average travelling distance of less than 51 kilometers.
Cruising range: 160 kms 160 km
Sustainability NZ Electricity Generation is currently 67% from renewable sources Government policy is for 90% generated from renewable sources by 2025
Emissions reduction The Ministry of Economic Development in it’s 2050 energy strategy has set a goal of halving carbon emissions from the transport sector by 2040. It is Government policy to reduce the rate of CO2 emissions per kilometre of light vehicles entering the fleet to 100 grams CO2 per kilometre by 2015 with corresponding reduction in average fuel used per kilometre.
Introducing Electric Vehicles in to New Zealand EV’s can readily and successfully be introduced into New Zealand with operation in most situations no more difficult than for an internal combustion powered vehicle. EV’s meet all the daily requirements of the vast majority of New Zealanders’ urban personal transport demands. EV’s do not require a large investment in infrastructure to begin introduction. High percentage of NZ homes have off-street garaging with power point. There are no barriers preventing EV’s driving on NZ roads. Nissan’s LEAF meets all current NZ safety standards. The Government has a policy statement that NZ should be a world leader in the deployment of Electric Vehicles.
