If everyone were to go to electric vehicles, how much would the electric grid be able to handle?  Is there generating capacity?
That's the beauty of electrics.  The current electric grid has an abundance of base load units (large coal, oil or nuclear generators) that cannot swing their output quickly.  They take hours to shut down and even longer to start up (sometimes days).  So, the power companies keep them running all the time and shape their generation output with other smaller (and typically more expensive to run) units like gas fired.  There is always (cheap) hydro but, at least out here, the amount of energy you can get from that varies greatly year to year.

When the load drops off at night, power companies are a bit flush with power and often have to sell it to distant locations.  That is when you have the electrics recharging - at night - making use of that extra power.

Now, throw in all the solar.  Somewhat cheap - especially if the home-owner purchased and installed it.  Now the power companies need to have more gas fired units to take over the instant a cloud bank affects generation.  And then there is wind, even more variable.

In the long run with solar becoming more dominate, the grid will need some better storage options (huge battery banks?) so they can stop building gas units.

This was an event to introduce a " concept vehicle " . Also to be first at it and it did drive onto the stage .  Volvo car manufacturer said it will only produce electric cars in 2019 , you can bet Volvo trucks will not be far behind.  Lots of variables but it is very close to being put into production.  I think Elon Musk is like PT Barnum he has his hands in many new and futuristic projects. This truck was supposed to be introduced earlier in the year , but they helped Porto Rico with some solar setups .  A long time ago we had electric milk trucks . I believe the range is 500 miles and pickup another trailer to go another 500 .

eastview mall, in Victor NY. has a Tesla charging station in the parking lot. From a distance it looks like about 10 spots. I have seen it being used.

There are charging stations at Rest Areas on the Florida Turnpike.  I haven't seen them anywhere traveling I-95 though.
Perhaps each Municipality is going to have them soon or in the Planning.

The City of Rossland (population 3500, more or less) has had 2 public charging stations for several years now ;D.

Aviation Mall in Queensbury NY has one too, I thought it was one of those vacuum stations until one day I seen a family plugging in a tesla and then going into the mall to conduct serious business.

They're pretty sparse in my area.  There is one in Harrisburg, the state capital.  Hershey has 4.  2 are at the Tanger's outlet mall.  One is at Hershey Park, and the other is at the Hotel Hershey.  All the others in the area are at car dealers.  The city of Philadelphia has a grand total of 13.  My county has none and none are in several of the adjoining counties.  There are 22 in the state of Delaware.  North Dakota has none.

Here's Tesla's map:  https://www.teslarati.com/map/

My understanding of the Tesla truck is that it is using 4 Tesla motors for power.  Those are rated at a 192 kW usage.  I looked at some other sites, and they are speculating roughly 1200 kW battery capacity for a 600 mile trip.  Estimated cost for the battery is $100/kWh or $120,000..  The estimated electricity usage is about .5 kWh/mile. 

The Tesla megacharger is rated at 1.6 Megs.  That's what is needed to charge a Tesla in 30 minutes for a range of 400 miles.  I'm thinking that the average truck stop is going to need quite a few of these chargers.  To produce 1 Meg of electricity with solar, it would take 4 acres of solar cells.  It would vary due to location.  1 charger would need minimum of 6.5 acres of solar cells.  That's a lot of land needed to power the megacharger with juice through solar.  Especially when you consider that you're using prime real estate to construct one.  Maybe I'm missing something.

There are many solar panels above parking lots or on rooftops . Our local UPS building has six million dollars worth of panels on the roof top. Also colleges and shoping malls . They seem to be showing up everywhere.

here is a crazy idea. Inductive charging stations built into the long lonely desert roads. charge your car while you drive :)

The roads would be solar cells.

Well, in California, years ago, Home Depot separated from the grid as I was told by a PG&E employee that actually did it in my area.  They run off of fuel cells.  Apparently, HD got such a screaming deal on natural gas that it was a no-brainer for them.  Until Dark Silicon becomes the standard, fuel cells may be the interim solution.

The boys and I were talking about this some on the weekend. A couple of things were brought out.
Electric cars were first an idea about 40 years ago? But it simply wasn't practical because battery technology wasn't up to the job. About 30 years ago or so I remember a car platform being tested but due to battery weight it could not pass any safety tests. 10 years ago battery technology improved to the point that an electric car became practical for urban areas where the car would primarily be used for commuting to work and back or simply for use within a short distance from home. Now it has improved again where electric cars have a range of use where they will become practical for many more uses.

The truck has come on the scene and its journey to practical use will be shorter than the cars as it can follow an existing technology trail. But it is still some distance away from being able to take over from diesel or natural gas. Like has been lifted out; distance between service points for diesel is one number and distance between natural gas service points is another. The diesel network has been established over 70 years? The natural gas network wasn't there in 2001 when I was all over North America but I see it in many truckstops now. So as technology improves over the next 20 years, where will we see the electric truck? Who knows? But it will certainly be different than what we see now.

I think the hydrogen hybrids are a bit better fit for trucks.  Easier to fuel, and longer range.  Use the solar to make fuel.  The hydrogen acts as a battery for storing energy.  Less weight for the battery array.  But, Tesla isn't making hybrids.  His business model is to make and sell batteries and to fuel cars. 

To replace cars and trucks to electricity would take 1,111 Terrawatts or an increase of about 29% in electric production.  I know there is a bridge necessary to get to that point.  That's a lot of infrastructure that needs to be constructed.

I have heard that Tesla would be out of business in 24 hours if govt money was cut off, true or not I do not know.

The self drivibng cars have been on the market for at least a couple of years. I have a friend here that has had one for that long. Great car, powerful and fast, but you can't make it to the next town, so worthless here as far as I am concerned.
Iirc it has been at least a couple of years since on of Elon Musks personal friends bought one and got killed in it in Florida, I think. Apparently the sun was shining on the side of a white semi van just right and the cars computer didn't recognize it as something to slow down for.
As far as electric trucks becoming the norm, hmmm I doubt many of us will live to see it.

I want to see how everyone plans to actually charge these electric vehicles if they ever become mainstream. Tesla recommends a 400 amp panel at 240 volts in most houses. In my area, most houses have 200 amp services, some only 100 amp. What happens when 30 houses on the block all get Teslas? The service into the area and transformers is simply inadaquate for the need....

Onesee twoseeies, sure no problem. Mainstream... good luck.

The "home" charge stations don't need to be as fast because you plug the car in overnight. Recharge in 30 mins needs a LOT less current than recharge in 10 hours. So the home charge station probably draws about as much power as a kitchen stove, just for a few more hours. You need a decent feed because you come home, plug in the car, then start cooking dinner.

Yes the power utilities will need to adjust to suit the extra load and different profiles. But not everyone is going to buy an electric car next week.

Good point, but I think you expressed it backwards: Recharge in 30 mins needs a LOT more current than recharge in 10 hours.
