# Energy Efficiency of Local Transport

16 Sep 2010

In terms of efficiency, I've calculated the efficiency of various forms of transport in terms of their Kilo Joules per mile <- Yes, I was bored :)

- Typical internal combustion engine car @ 30 mpg = 5346 KJ/mile
- Tesla Roadster Electric Vehicle @ 0.28 Kwh/mile = 1008 KJ/mile
- Cyclist @ 700 calories per hour = 195 KJ/mile
- Walking @ 2.5 mph (256 cals per hr) = 306 KJ/mile
- Swimming @ 700 calories per hour = 1464 KJ/mile
- London Tube @ avg 20mph = 214 KJ/per passenger/mile

Note: Transport for London claims "143 Watts/passenger km travelled" for tube travel. I assume they mean watt hours.
