Maybe, but we won’t be burning it in cars.

...or ride your bicycle from your chic new downtown studio condo (the one that will put you in debt for the remainder of your life). however, you are now woke, so it is ok.
I bought a new Tundra with a big V8. It will probably last until I die. The Camry has 35,000 miles so it will probably keep chugging along for a couple of decades without issue. I’m hoping if I live long enough they will either have a huge breakthrough in electric...or realize the STUPIDITY and go back to building gas engines.
Folks need to remember: Electric vehicles are not “emission free”. They are “displaced emission vehicles”!
A hybrid fuel electric power train avoids this infrastructure nightmare.
Right now, the fuel power train component is usually a small (@25 hp) gasoline engine. It powers an electric generator that supplies electricity to charge the car’s battery or directly power the electric motors inside each wheel hub. The power management system turns the engine on and off as needed, routes power flow, etc.
It avoids the infrastructure impacts by allowing gas stations to remain gas stations. Demand for fuel decreases because many low speed, short duration trips are being performed using only battery power.
This is actually a transference because the slow nighttime home recharging envisioned to keep EV batteries topped off still requires electricity to be generated somewhere and transferred to the home charging portal. However, efficiency of scale does apply as the power plant/electrical grid system can generate electricity at lower unit cost and lesser environmental impact when properly engineered/re-engineered to do so.
Our current approach, however…
I’m reminded of a saying attributed to British diplomats when discussing America’s approach to foreign policy. It seems weirdly appropriate to the “woke” US government approach to this problem as well:
“In the end, the Americans will do the right thing. But only after trying every other solution first!”
God help us. And God bless America.
Will there be serious grid capacity issues if even half of our cars switch over to EV's? Yes.
Will they all be clamoring to charge at a charge station once per week like we all do at gas stations for gas cars? No. Like others have said, EV's are charged at home except for the rare times they're used for long trips.
Can they be charged with solar at home? Yes. Like Brian said, a daily commute is usually a small percentage of an EV's range -- no requirement for every day to be a sunny day. However, there is the issue of usually being gone during the day for work, then coming home in the evening when there's little to no sun left. Do that 5 days per week and you might be about out of charge. For example, I usually drive about 200 miles per week, and the EV truck I'm thinking of getting has an official range of 230 miles. Let's assume draining the battery 80% regularly, that's a realistic 184 mile range. So I need on average 16 more miles of charge between weekends (when the EV would be home during the day to charge from solar). That would mean needing only about 9 kWh needed throughout the weekdays -- I promise you my 10 kW solar panels can eek out a few kWh in the late sundown time to get 9 kWh across 5 days. Plus there's the fact that my home solar batteries have a usable storage of 21 kWh (really 30 kWh total, but I drain them only 70% to extend their life beyond the 19-year warranty). On average I need only 16 kWh to power my house at night without pulling from the grid before the sun comes up enough the next day. So that's 5 kWh extra power I can use to charge the EV each night.
So if I get an EV, I'd have the electrician install not one, but two 240V charging outlets. One would be powered with constant power like most outlets. The other would be powered intermittently, only when my solar inverter recognizes my home batteries are charged at least X percent (say 85%). When I get home with the EV and plug it up to charge, I'd choose which outlet to charge it in. If I have, say, over 40% charge in my EV battery, I'll plug it into the intermittent powered outlet. I'd do that knowing it won't charge all night, but will charge until my home batteries discharge to 85%. If I come home with below 40% EV battery charge, I'll plug it into the constant powered outlet (knowing that some or all of that power will come from the utility grid like most people charge their EV). That doesn't make me 100% powered by solar power. But it moves the needle a lot to free my budget from worrying about the Dims jacking up power rates. If I have to buy just a little of my power from the grid, I can live with that.
That's why I got the solar system and that's why I'm thinking of getting an EV. Not to slay some invisible make-believe carbon breathing dragon. I don't believe in the Church of Democrats. I like my solar system and I'm thinking of getting an EV to free me from the shackles that the Dims put on us with sky high energy costs to force us to repent from their sins.
Doesn’t matter.
Article says “10-amp”.
Engineers and accountants will use calculators and spreadsheets, and their brain cells.
“Doesn’t matter.
Article says “10-amp”.”
Again, no such thing.
The common suggestion that EVs can simply be recharged at night overlooks the fact that over night is when there is no solar and, frequently, little wind. The power supply will have to depend on storage. It will require huge expenditures and technological advances to exist at necessary scale. Supply will have to meet not only the vastly increased demand due to EVs, but also the usual preexisting demand.
“That’s about 30 100-watt panels in a very sunny area for an 8-hour/day office worker.”
Thanks! Guess that person should get a night shift.
“an EV charging station would require 600, 50-watt chargers”.
50 watt charger???
Stopped reading right there.
Prolly meant 50 amp but still....
The oversized electric golf kart fanbois will not be pleased at the mockery of their fetish.
Presently there is about 50% excess capacity at night.
Tell the author of the article.

Probably better cars than you drive.

I'm holding on to my vehicles. At 65 and a year out from probable retirement, there is no incentive to sign a contract to pay off another vehicle. The SARS-CoV-2 pandemic may wipe the market for new sales. I got through BA.1 without severe consequences. BA.2 really likes lung tissue and binds ACE2 1.4x more effectively than BA.1. BA.2 is more pathogenic as well.

You mean the condo that DHS has you sharing with the six illegal immigrants? Hopefully one of them hasn’t hocked your bicycle.
