The Federal Government is propping up a dying technology as electric cars' potential soars.
The South Australian Premier. Mike Rann, says he is "confident" that General Motors will agree to manufacture an electric car at the Holden plant in Elizabeth. After his discussions in Detroit with GM's chief executive, Fritz Henderson, Rann said the prototype battery powered Volt could be built on an existing production line at Elizabeth.
Sounds good. Perhaps Prime Minister Kevin Rudd or his Industry Minister, Kim Carr, should have taken themselves off to Detroit for similar discussions with Henderson before announcing the Federal Government's $500 million Green Car Innovation Fund to build-low emission vehicles in Australia. The Government is showering money on the Australian car industry, the latest example being a $200 million line of credit to Holden.
This is making no discernible difference to the business-as-usual mindset at the car maker, which has announced it will continue to produce the Commodore with a V6 engine. Although it will be 13% more fuel-efficient, it will not quality for green car funds. The Commodore will produce 221g of greenhouse gases per kilometre, compared with the 130g fleet average the Europeans will move to by 2012. (Reports suggest that this is also the target set in China.)
Meanwhile, Holden is sticking with petrol, despite having access to $150 million from the green car fund for its small cars. The Australian's motoring writer, Philip King, reports that $200 million of the scheme will be used to import General Motors-Holden's small-car engines, developed by foreign technology. While the Government insists that the money it is handing out is essential for the car industry, it lacks any clear vision of the future.
Sooner or later, petrol will no longer be used in cars. The world is starting to focus on electricity-powered vehicles, where the most recent developments are promising. Under the Better Place battery-swap concept, for example, a $500,000 machine at a service station will allow car owners to swap fresh, fully charged batteries faster than filling tip the tank. With larger production runs, the capital cost will come down, and the technology will improve as battery technology - being feverishly worked on overseas but not commercially in Australia - increases the power and life of batteries. Better Place also envisages charge spots at homes, shopping centres and workplace car parks.
Hamilton Island, the centre of the Whitsunday Islands' tourist industry, provides a glimpse into the future. Hamilton is about as big as a small suburb or a medium-sized country town. The locals all use electric buggies, rather than cars, to get around. Anyone who has driven an electric golf buggy knows they are much simpler and lighter than a car: no clutch, gears, cooling system, oil filters, etc. The lack of traffic noise is striking.
Electric cars of the future will not be much different from today's golf buggy, although they will have a car body shell, more comfortable seating, a boot and a much more powerful electric motor. Simply avoiding the production of bulky petrol or diesel engines and complex automatic gearboxes, wherever they are made, would significantly contribute to emission reductions. Electric cars will be so relatively simple to manufacture that existing car makers could find themselves competing with new players. The production of efficient electric cars will inevitably lead to the development of electric trucks and buses, the latter will make a key contribution to improved urban public transport and the reduction of not only carbon dioxide but also city smog. The Federal Government should be applying pressure to get real value out of its green car fund.
True, a battery car is not emission-free, as recharging the batteries uses the product of coal powered generators. Yet even with brown electricity, the contribution of battery cars to greenhouse gases is far lower than that of petrol or diesel vehicles. But coal-power generation will continue only if geosequestration is a goer. If it fails, power stations will be run by gas, in the medium term, on the way to 100% power production by renewable sources. In NSW, where the Hunter is the centre of coal power generation, geological conditions are unsuitable for holding liquid CO2 underground; nor is the outlook good for injecting CO2, into safe storage underground in all of NSW and Queensland.
The Nationals would be wise to rethink their present policy of mandating a 10% ethanol petrol mix. Like petrol, ethanol has a limited future. Further, as the world approaches a food shortage crisis, Australia is using its grain to produce ethanol. Nationals MPs, almost to a man - and perhaps a woman - are climatechange deniers or sceptics; the party's Senate leader, Barnaby Joyce, being the most vocal. Perversely, although Joyce and others ignorantly claim that the Government's emissions trading scheme will wreck the Australian economy, the Nationals' federal council voted narrowly last month in favour of gross feed-in tariffs for small-scale renewable energy systems.
Joyce and the party's dinosaur, Ron Boswell, opposed the policy and lost the vote. Boswell's astonishing reaction to this was to declare that he would work to ensure that feed-in tariffs do not become the party's policy at the next election. He said, accurately, that the feed-in policy was more like a Greens policy than a Nationals policy, which is hardly a sound basis for its rejection: it's either good policy or bad, irrespective of which party proposes it.
Like the Liberal Party, the Nationals are also split on climate change. Nevertheless, their highest policy body has now conceded that climate change is real and that it is at least in part caused by human activity. The council also urged the Federal Government to work with the states to introduce feed-in arrangements.
If feed-in policies operate, then sunny Queensland, represented in the Senate by Joyce and Boswell, would be ideally placed. Householders could gather all their energy needs from rooftop photovoltaic panels, with any excess power sold into the grid to help pay off the capital cost of their rooftop investment. Such households could also have cheap, plug-in facilities for their electric cars.
