How much can electric vehicles reduce Australia’s carbon emissions, and what are the factors limiting the transition from Australia’s fleet of conventional combustion engines?

In pursuit of the goals of the Paris Agreement on climate change, now in force, the 2°C scenario of the International Energy Agency attributes more than 300 Gt of avoided carbon dioxide emissions by 2050 to a revolution in electricity generation. Industry is supposed to contribute about 150 Gt, with transport just behind at about 140 Gt.

The challenge to meet the goals in all sectors is immense, especially in electricity generation, so is it a good idea to add to the demand for electricity by a global rollout of vehicles powered by electricity?

Battery-Electric Vehicles

When most people think of an electric vehicle, they imagine a battery-powered car that is plugged into the electricity mains to recharge the battery. In these battery-electric vehicles (BEV), an on-board battery provides electricity to run the electric power train. In its May 2016 summary of the global electric vehicle outlook, the International Energy Agency reported that the number of BEVs had passed 750,000 (http://tinyurl.com/IEA-2016-EV-outlook). More than 20 manufacturers now offer highway-capable BEVs.

Most people also know about range anxiety – that awful feeling that you will run out of fuel before reaching the next refuelling station – in relation to BEVs because most...
