Lot of mis-information on this thread.
Some updates from 2021
EVs only use about 250 watt-hours per mile. Means for Retail Electricity (13 cents, US average kWh) compared to Retail Gasoline (about $2.50 to $3.00 US Average) . . . Electricity cost less than 1/3 to 1/4 of Gasoline. Numbers are even better for Diesel. If you charge from local Solar PV, the EV can drive for Zero Fuel Costs.
The US 2020 Grid Generation was about: 40% Gas, 20% Renewables, 20% Nukes, and a little under 20% Coal. Coal is dropping like a Rock, and Silicon Solar PV is just about all that is being built for the next 3 years (looking at permits for 2021 - 2024).
Actual losses from Electricity Transmission and Distribution are about 5%, US Average.
Full construction and install costs for New Solar is:
$3 per Watt (or less) for Rooftop Residential
$2 per Watt (or less) for Commercial
$1 per Watt for Utility Scale.
Wholesale Solar PV Generation is going for as low as 1.5 cents per kWh, all Capital recovery, all expenses, operations and maintenance included.
We can run the whole US Grid from Silicon Solar PV. Yes, the whole thing. Not really a good design to single source things, but yes we can, for less cost than the present or other options ahead. Since this can all be placed on existing "Manmade Impervious Surface" (fancy words for Rooftops, Parking Lots, etc), this can use little to no additional land space.
All Ground Transportation can be moved to Electricity and only increase total Electricity Use by about 10%. As this would spread across 20 years or more, this is 1/2% per year. This is barely noticeable, as we plan on a 1 to 2% growth per year.
Big Batteries are likely a "pass-through" phase as Electric Roadways (power comes from Road) improve and expand. Electric Roadways will allow the various .gov(s) who own maintain the roads (Fed, State, Local) to get the retail mark-up for Electricity and fully fund the system, as well as fully replace current Fuel Taxes, while costing EV owner-operators less than 1/2 of present ICE fuel costs.
Here are some samples:
Future of Electric Tractors may be connected, rather than batteries, as well. Sample here >>>
