Keep in mind that there is a variable cost to transport the gasoline as well; you need to fuel tankers, power refineries, and fuel the trucks to transport the fuel to the pump.
- r00fus 14y agoYes, it would be a pretty ridiculous situation where the EROEI [1] calculation would favor gas-powered car engines vs. coal-powered electricity pumped through grids and stored in batteries. Gas powered motors are still less brittle than grid-powered ones - it'd be tough to power a military force on grid power for example, but at that scale we should be using local fission powerplants anyway (ie, nuke subs).
