That’s if it is charged on an electricity supply that is delivered by fossil fuels. (This link provides some calculations showing why this is so.)
On the other hand, an electric car that is charged by a renewable power supply will pollute less and use less energy.
Before we jump to any half baked conclusions about the wisdom of Tasmania’s car fleet switching to electric, its important to add three caveats ... :
