Australia’s ‘electric car revolution’ won’t happen automatically – Graciela Metternicht and Gail Broadbent
Electric cars might finally be having their moment in Australia, after British billionaire Sanjeev Gupta approached the South Australian government about retooling Adelaide’s defunct Holden factories into a new manufacturing hub.
Recently the federal energy minister Josh Frydenberg wrote that as costs fall, Australia will “inevitably” see an electric car revolution. He cited surveys showing up to half of Australian motor- ists would consider going electric the next time they buy a car.
But falling costs alone won’t convert consumer sentiment into actual sales. Our research – partly covered in a previous article on The Conversation – examines how different countries handle the three major issues: vehicle cost, recharger availability, and demystifying the public.
Our research shows that the most important factor that affects consumers’ decision to buy an electric car is the availability of a fast recharging network, especially on long trips away from home.
This was far more important than the availability of cheaper vehicles, the second most cited barrier to uptake.
Even if people can afford the available electric car models, they also need to be assured that they can recharge conveniently and quickly on those long journeys they occasionally make during the year. We need to be ready for this transition.
While there have been commendable efforts to build infrastructure, including by Queensland’s Labor government and the NRMA, there needs to be some federal coordination, for several reasons.
Firstly, standards are needed for the recharging plug; there are quite a few types out there, and to avoid having some very unhappy investors this issue needs to be urgently addressed.
Secondly, not all electric models can accept superfast direct current charge in addition to the usual alternating current used in household electricity supplies.
Thirdly, having cars with a bigger range does not mean that you can do without rechargers on major intercity roads and in country towns.
Australia needs a comprehensive net- work. This means fast chargers with standardised fittings available every 50- 100km on highways and in country towns. An app to help motorists find their nearest recharger – without locking them into membership of any particular company – are essential.
What about charging at home?
While a nationwide network of chargers is important, most people will wish to recharge their cars overnight. This raises another question: how many people have access to a power point within a few metres of where they park?
For people with garages, it is unlikely to be an issue. But apartment living is increasing every year in our big cities, and there are plenty of suburbs where off-street parking is not the norm.
Ideally, federal regulations would step in to ensure that apartment-dwellers don’t end up having to be electric car have-nots. We can look to California for an example of legislation that can inspire Australia.
Making it easy for people to recharge at night could also allay fears about increasing demand on the electricity grid. If the cost of off-peak power at night is lower than during the peak, people will get into the habit of flicking the recharger switch on when they go to bed.
It would make sense to ensure that everybody has access to off-peak pricing; people will then act in their own financial self-interest and recharge at night if they are given the opportunity.
In fact getting everyone to go electric as quickly as possible will save us billions of dollars in imported oil. During 2016 Australia imported almost A$15 billion worth of refined petroleum, much of it for road transport. We could fund a lot of infrastructure with the money saved.
As Frydenberg pointed out, electric cars are getting cheaper. The cost of a car’s batteries, the biggest single factor in its overall price, is falling. It is reasonable to predict that electric cars will cost the same as their conventional combustion counterparts within a few years.
Charging with electricity is also cheaper than filling up with petrol or diesel, and especially once home solar is taken into account.
There are other hidden costs to conventional cars that need to be taken into account. For example, the burning of fossil fuels is known to cause cancer and asthma. And Australia is currently one of the only developed countries in the world without minimum fuel efficiency standards. This is an astonishing state of affairs.
