“Does anybody ever consider just how much electric energy it takes to push a two ton vehicle down the road?”

Less than the gasoline energy required.

For true applies to applies comparison, you have to include all the energy requirements to produce electricity with all the energy requirements to produce oil, not just the efficiency of electricity and oil. That calculation has to include the creation of all the industrial components behind the energy source.

Most folks do not address this (very complex) issue at all.

Actually, the same amount. Except we have a LOT of oil. Also, though batteries are getting better, you have to haul a LOT of weight around to get any range. A gallon of gas holds a LOT more BTU’s of energy than the same amount of battery weight. This covers the problem really well:

The Model 3 Tesla takes one fourth the energy to move down the road of a comparable in size and weight car. The Model 3 takes 250 watt hours per mile or put in kilowatts it goes 4 miles for each kilowatt hour consumed. Gasoline the E10 that urban areas must use is 114,000 btu HHV per gallon one kilowatt hour is 3414 btus so a gallon of gas contains 33.39 kwh of energy a model 3 Tesla will travel 133.56 miles on the equivalent energy. NO COMMERCIAL ICE vehicle can touch that efficiency not a single one. Electric motors are second law of thermodynamics machines , internal combustion are third law and can NEVER approach the efficiency of a electric motor for energy conversion into physical motion. Note that the 250 watt hours per mile is gross energy usage as in from plug to charger to batteries to inverter to motor to wheels. Which means the electric motor is even more efficient taking into account the round trip to and from the battery pack sorry EVs are the future it’s only a matter of time till the cost per kwh of storage drops below $100 at that point no internal combustion engine can complete on a cost per mile at even 15+ cents per kwh retail. Tesla is at $125 and falling once they get there new Austin gigafactory open they will be dang close to $100
