I did come off a bit negative on electric cars, I am interested, But I am also not convinced the best path to reducing our environmental footprint is battery cars.
> I didn't leave out transmission losses, I specifically mentioned them.
You underestimate the true losses with that. It takes a lot more energy to build and maintain the grid, which is not capable of supporting more than a small percentage of households having electric cars today. For example is a gas pipeline and gas tanker 100% efficient, because all the oil that goes in comes out? The cost is as good of estimate of the true environmental cost, and it is currently $.05 to generate electric, but $.12 for electric delivered.
Your correct I vastly overstated the weight difference.
>Tesla Model S = 4,608 to 4,936 lbs; range = 208 to 315 miles.
the 85 kwHr even by Tesla's numbers is maxed at 265 miles. The weight you stated is not for that P100D. To be fair the Tesla is 2* the weight of my Chevy Cavalier which also has a 300 mile range. Definitely difficult to compare apples to apples, as they electric does fill a vastly different purpose today.
> whether there is an increase in load due to electric vehicles.
I don't agree. With solar, battery packs, low cost standby generators... Were now able to make self sustainable houses with very little need for a grid, with few downsides. If we don't try and charge cars off the grid, we could be looking to downsize, and at least eliminate the huge interconnects into residential. The mega and always growing electric grid just cannot ever eliminate it's huge footprint, if we keep finding new uses for it.
