Lets try to not let every conversation here about alternatively fuel cars be so teeter toter lopsided. electric cars were quite popular in the early 1900's I did a research paper on the platform in my under grad. Henery fords wife drove an oldsmobile electric.
a great research source is old car muesums, the dusenberg, muesem has a great display of the 30+ domestic car manufacturers of days gone by.
in regards to the grid the rural electrification act in the 30's gave the grid its needed boost to help farmers feed america better. before that power was an onsite affair. after 1888 the edison electric leight system was a system you could purchase and install in your home. many homes of the day had gas lights and battery power for the door bell, the soon to be new technology of radio or other needs. when you bought the lighting system , you got a power plant with it. You could spin it any way you wanted. the first edison system on the north american continent was spun with falling water from a near by paper mill. New york had the second system and it used steam.
electrical energy availability is not the electric cars problem... the losses in conversion is the GIANT IGNORED elephant in the room on alternative transportation. If you had to burn/waste a quart of gas to fill your car with 10 gallons of gas you would be pissed. yet the knuckled heads that scream electric propulsion is pollution free and green, chose to ignore that tiny little component of the process. refining crude is horrible, and so is the inefficiency of power conversion to charge a battery.
the on site electric motor generator set, (MG sets) were actually fairly good input to output ratio compared to the PWM chargers of today. history repeats itself, our task is to improve and get better.
