Did you know...
"...when a car is driven, only about 20-25% of the high-quality chemical energy available in its gasoline fuel is converted into mechanical energy (to propel the vehicle) and electrical energy (to run its electrical system). The remaining 75-80% is degraded to low-quality heat that is released into the environment and eventually lost into space. Thus, most of the money you spend for gasoline is not used to get you anywhere."
This i found when reading my General Ecology book...at least there is something of interest in the book!
