Damn interesting question..


https://d28rz98at9flks.cloudfront.net/70142/70142_complete.pdf

Table 2.6 Australian energy production, 2007–08

coal production 9431 (8722 penta joules black ) + 709 penta joules

Table 2.7 Australian primary energy consumption, 2007–08
coal consumption 2272 penta joules


so for every joule 4.15 produced your get 1 joule to consume ....or 24% efficiency for coal... in 2008..

I have seen a report with 3 times more recently in it so for 11 years ago 24% moving to 28% now..

This would get you to the power point ....

You need to work out how much charge you lose during charging the Battery ...

then you need to look at the efficency of delivering the energy from the battery to movement of 1 km .

Fascinating problem...will take a bit of time to work out ...any Mechanical/ car engineers out there ?
