Shifting our vehicle fleet to renewable electricity is an obvious and urgent action if the government is to achieve the greenhouse gas (GHG) emissions target it set itself last year in the lead up to the Paris climate conference. A recent report by Concept Consulting confirmed that electric vehicles (EVs) would be a sensible way to reduce our GHG emissions.
The issue, how can we speed up the conversion of our vehicle fleet from gas guzzlers to clean electric?
In Norway, which generates almost all of its electricity from renewable sources, 25% of all new car registrations in the first quarter of this year were plug in electric vehicles. The country now has around 70,000 EVs. By contrast, there are between 1,500 and 1,600 EVs currently registered in New Zealand.
So what can we learn from Norway? Firstly, the government started pushing EVs 20 years ago and developing an extensive recharging network. Secondly, EV owners escape some of the charges faced by those still driving fossil-fuelled cars; for example: road tolls, which range from $NZ5 to $7 a trip and parking fees, which can be as high as $NZ500 a month in the major cities. Thirdly, new cars in Norway have always been heavily taxed (including a net worth tax), often doubling the cost of a new car to around $NZ60,000. EVs escape this initial swinging tax making them price competitive with conventional cars.
The New Zealand government has set out its programme to encourage EV uptake with the aim of doubling the number of electric vehicles every year to reach approximately 64,000 by 2021:
- Extend the Road User Charges exemption on light electric vehicles until they make up 2% of the light vehicle fleet
- Investigate the bulk purchase of electric vehicles
- Government support for the development and roll-out of public charging infrastructure including providing information and guidance
- $1 million annually for a national five year electric vehicle information and promotion campaign
- A contestable fund of up to $6 million per year to encourage and support innovative low emission vehicle projects
- Allowing electric vehicles in bus lanes and high-occupancy vehicle lanes on the State Highway network and local roads
- Establishing an electric vehicles leadership group across business, local and central government
The target of 64,000 EVs in New Zealand by 2021 is bold, but the above initiatives seem very unlikely to do much to get us there. The Government should look at partnering with the major electricity generators to speed up the adoption of electric cars. Given there’s surplus generating capacity (partly a result of climate change) the electricity companies have a strong incentive to open up a new market for their product. EVs could be a great way to spread generation load.
The proposal for the government and private sector to perhaps bulk purchase EVs could help narrow the cost gap in the short term and over the medium, as manufacturers gear up EV production and EV technology (especially batteries) advances rapidly, these vehicles will become increasingly cost competitive.
A 2016 survey of car companies in New Zealand by the Motor Industry Association indicated that between now and the end of 2020 car companies expect to introduce at least 44 new EV and plug in hybrid EV models into this market.
While the lack of an extensive charging infrastructure may seem a major bottleneck for the roll out of EVs, there’s also a risk that technological advances will reduce the need for a charging network, or at least change the type of recharging network required:
- Firstly, battery technology will improve, and possibly dramatically, meaning most recharging could be done at night at home using existing power outlets. Battery technology is being pushed along by intense demand from a whole range of device and products. Lithium air batteries, which can theoretically store four times the energy/kg as current lithium ion batteries, are a step closer to commercialisation according to a recent article in The Economist.
- Secondly, car manufacturers are bridging the battery technology and charging infrastructure gap by producing plug in hybrid cars that all but eliminate the range/ recharging problem of fully electric vehicles.
- Thirdly, induction charging technology is improving rapidly and could lead to dynamic recharging or at the least much more convenient recharging in car parks at supermarkets, roadside cafes and in car parking buildings. The University of Auckland is a world leader in this area of pure and applied research.
EV technology is advancing quickly and will lead to significant changes in private transport services over the next decade or two. It’s worth considering how fast and far mobile phone technology has advanced over the past dozen or so years. A similar revolution in the car industry could easily be driven by mounting pressure to reduce GHG emissions.
