Yup, and the entire time those pedestrians & bicyclists are on there they are either peddling or walking in a hamster cage to generate the power necessary, correct?

One huge energy source that is almost undeveloped is geothermal. The whole world is waking up to that thanks to the demand for battery lithium.
I've was around geothermal plants in my youth, do you know what a maintenance nightmare they are? The Sulphur, etc destroys vanes, piping, boilers, etc, etc. How much do you save if you are changing out parts all the time to keep it running? How much (in the way of emissions) crap, as many call it, is put up in the air producing the spare parts? Since you probably live close to El Centro (from Salton sea inference) check with the maintenance folks that work on those dirty plants around there.

Yes, the limit on geothermal has been getting them to run profitably. If processing geothermal brine is a profit center, they move from being a power generation plant to being a co-gen facility. Geothermal is well understood but, as you point out, it's outrageously expensive to run. Brine mining might tip the scale a bit. Nobody is in the business of making electricity for free.
Like it or not, I think we're going to move away from fossil fuels. Geothermal is one of the power options, but so far it has not been profitable. It has the advantage of being up 24/7, except when the plant breaks down.
What are our options? I'm not a fan of solar because of things like night, clouds, and snow storms. Wind would be an option if we had long distance electrical transmission, but we don't, and nobody is building it. River hydro is built out, and tidal hydro has few practical sites. Nuclear has an uphill political battle.
As others have pointed out, it makes no sense to convert the world to electricity and then use fossil fuels to generate the electricity. My crystal ball gets fractured any time I try to guess the future. Maybe power generation will become a cottage industry, with solar cells on every house. That might keep the family flivver running, but it's not going to run steel mills.

Almost no shopping center has fast charging bays, at any price.
What is fairly common (and near useless, but "it looks like one is helping") is a 7.2kW J1772 L2 EVSE. It is not a charger, is Electric Vehicle Service Equipment. It is little more than a smart extension cord. These cost about $500 for hardware plus installation.
A Tesla Wall Connector is $550 for up to 17 kW. Not all Teslas can accept the full 17 kW. Requires a 240VAC 90A circuit. If you install close to your distribution panel then parts will be less than $100. A Tesla Wall Connector comes with the car. My old one was 9.6kW for the full abilities of a NEMA 14-50 (the common RV 50A hook up) but newer may be a bit less.
Tesla does not sell Superchargers to individuals or companies. Based on construction permit filings it is estimated to cost $50,000 per charging bay. Building something safe enough idiots with drivers licenses can make 120 kW (newest is 250kW) electrical connections is not cheap or easy. 400V DC at 300A for 120kW.

I can't charge a vehicle via a photo.

My Model 3 SR+ Red Tesla is scheduled to be delivered on the 15th. Delivery date was moved from Oct18-Nov07 to this 15, I'm pumped
Went with the SR+ because in Québec, we get a $8,000 payback (on top of the $5,000 the federal gives at purchase) on any electric vehicle below $60,000 MSRP. Model 3 LR is over that amount and it then become way too expensive compared to the SR+.
My daughter bought one last spring and we calculated that going back and forth to the cottage (200 KM total), it costs her (well, me since she charges at home lol) the same amount it cost my old SUV (Tucson 2013) for the prorated cost of a oil change for 200 KM So actually, the cost of gas saved is 100% saving

You inferred you wouldn’t know what one looked like.
