There would be no difference in kind between the power needs of wireless power
transfer to charge electric vehicles as opposed to charging a car with a wired
connection.
I don't believe that the issue with respect to the power grid will be one of
generation. As Jim points out, that is being ramped up and as more EVs are
used, power demand may increase, but it will be a gradual change, not an
overnight one.
If there is a power-distribution issue it is that in many cases, from what I
have been told, distribution lines are operating near capacity and as gasoline
vehicles are replaced with EVs, we may see more overtaxed distribution lines as
a local problem.
Amateur radio does have concerns with the EMI potential of WPT-EV systems, but
we need to be very careful not to raise those concerns outside our standing,
especially if we cannot offer irrefutable technical support for positions
taken.

Please, long range planning w/o consulting the engineering teams
directly involved? Central Planning is a quite wasteful way to do
things. Fortunately Texas is out from under most of FERC's thumb
on account of our separate 'grid' that does not cross state lines.
On top of that, there are new primary energy sources on the horizon,
with lab testing and demonstrations taking place (and planned) even
as I write this that is going to challenge the "central gen" model,
thereby rendering a lot of this new 'planned' infrastructure into what
is called "stranded assets", and paid for out of my pocket. See, that
is where it hits me, and you, Jim

You may need to get your news from better sources, like Wall Street
Journal, NY Times, Wash Post. The current administration's

capacity and well as distribution. Just as current capacity is quite
sufficient for the current number of EVs, as more are sold, so will
there be more power.
I'll be 80 in the fall; we bought a Tesla Model 3 as our contribution to
leaving our planet for our grandchildren. It IS much more economical to
run and maintain over the long term, but it's unlikely we'll be able to
drive it long enough for it to pay US back. We love the car -- it's
quite well engineered. Several neighboring hams, including N6TV, W6JTI,
W0YK, W3AB, and W6GJB drive an EV -- mostly Tesla, but also Chevy Bolt.
All are made in the USA, and all of us are quite happy with them. They
have STRONG acceleration, handle well, and are a pleasure to drive.
My wife is also quite happy with the Prius she bought about six years
ago. Meanwhile, my big Toyota 2006 SUV, bought new in 2005, sits in our
driveway, with about 210,000 miles on it, not having moved in nearly a
year. We're keeping for hauling stuff too big for the cars we drive
every day. I loved it for all of the 15 years it was my primary vehicle,
but it drinks three times as much gas as the Prius.
