> Existing overnight electrical generation can satisfy replacing every internal combustion vehicle with an electrical vehicle, today, in the United States. This isn't so obviously true that it can be asserted without justification. Based on the statistics I'm seeing from the EIA, replacing every light-duty automobile in the USA with a Tesla Model S would increase demand on the electric grid by more than 50%. https://www.eia.gov/tools/faqs/faq.cfm?id=96&t=3 https://www.eia.gov/tools/faqs/faq.cfm?id=96&t=3 https://www.eia.gov/energyexplained/index.cfm?page=gasoline_use https://www.eia.gov/energyexplained/index.cfm?page=gasoline_...

"The US Department of Energy’s Pacific Northwest National Laboratory calculated that the grid’s excess capacity will support over 150 million pure electric vehicles. 150 million means that nearly 75% of the vehicles on our roads today could be electric and the grid would have the capacity to support them all." That leaves 25%, right? Right. Considering this is three years ago, it doesn't take into account the rapid expansion of solar and wind generation capacity (which is ~98% of all new generation capacity in 2016). The production tax credit has been extended for another 6 years; you're only going to see more wind and solar projects on the horizon. http://www.greentechmedia.com/articles/read/The-U.S.-Solar-Market-Now-One-Million-Installations-Strong http://www.greentechmedia.com/articles/read/The-U.S.-Solar-M... “It took us 40 years to get to 1 million installations, and it will take us only two years to get to 2 million,” said Dan Whitten, vice president of communications at the Solar Energy Industries Association (SEIA). “This is a time to mark when the solar industry started to accelerate at warp speed.” "At the end of 2015, the U.S. solar market hit a total capacity of 27 gigawatts. That represents just 1 percent of the current U.S. electricity mix, but it could triple to 3 percent by 2020. This year alone, the U.S. solar market is projected to grow 119 percent, which represents an additional 16 gigawatts of new installed capacity and more than double the record-breaking 7.3 gigawatts added in 2015." Did you know they give wind power away for free in some parts of Texas because of the excess power they can't transport out? Delicious, clean wind power for electric vehicles. http://www.nytimes.com/2015/11/09/business/energy-environment/a-texas-utility-offers-a-nighttime-special-free-electricity.html http://www.nytimes.com/2015/11/09/business/energy-environmen... So! You said my assertion wasn't obvious. I concede that is correct. The statistics you're seeing from the EIA are grossly inaccurate for comparing internal combustion vehicles to electric vehicles when you compare how much more efficient an electric vehicle is. I stand by my thesis: the current US electric grid has sufficient generation capacity to support 100% electric vehicles
