Low energy efficiency is already a major problem for petrol and diesel vehicles. Typically, only 20% of the overall well-to-wheel energy is actually used to power these vehicles. This low energy efficiency is the primary reason why fossil fuel vehicles are emissions-intensive and relatively expensive to run.
The other 80% is lost through oil extraction, refinement, transport, evaporation, and engine heat.

Sylvia Wilson drove around Australia in an electric car. It cost her $150.90.
Wilson, 70, a retired farmer from near Biloela in central Queensland, had planned the trip of a lifetime with her husband, Rod. One impulsive evening in mid-2016 they went online and, sight-unseen, bought a Tesla S75 electric car for the journey.
