Just my perspective after working 30 years in electric generation on how EV's and infrastructure are about to clash. There are only a few viable ways of making commercial electricity, coal, gas, nuclear, and wind. Solar is OK for individual houses but solar farms aren't commercially a thing (yet). Wind power is awesome as long as there is wind, it knocks birds and bats out of the sky with alarming regularity and has the grid going up and down like a pogo stick, which is why the government requires extra "spinning reserve" from base load plants for operators with wind farms to absorb the fluctuations on voltage on the grid. Depending on where you live the grid is made up of 345 KV on up to 700 KV distribution lines. Those lines feed substations where the voltage is reduced for distribution, typically about 7KV. That's what is feeding your transformer on a pole in the backyard or pedestal base before it hits your house (in the USA) at 240 VAC. As demand goes up generation has to increase, putting more electrons down the wires. Those wire respond by heating up from the current flow (check out the wires in your toaster for this effect). When the system current flow gets really high the heat load causes the wires to elongate creating more sag. No big deal until it contacts something grounded, like a tree. That's what caused the great 2008 Northeast blackout, a single tree in a neighborhood. So in the densely populated Northeast corridor we switch all the gas guzzlers to EV's and when summer hits all those folks plug in at 5:30 PM getting home from work, flip on the air conditioning and the system overloads, consequently nobodies bus, car, bike, skateboard, gets charged, and transportation comes to a hot sweaty halt while tempers flair over the countries utilities not making enough electricity. Here's the rub: US government mandated deregulation back in the 1980's forced electric utilities to separate generation from distribution. The two sides are not allowed to talk to each other, at all. It's considered "insider trading" if distribution knows what generation is doing. The kicker is nobody can make a profit from owning the wires all that electricity is flowing over. So why would anyone spend a nickel to put more wire up? You can't profit from it, it' requires routine maintenance and you could only get a tax break once. Until the US government wakes up and smells what it's shoveling the system can only degrade.
