That's great, but I'm willing to bet that most of the power to charge those EVs is not solar. I typically charge at night, after I'm home from work/gym/etc. That overnight power isn't coming from PV. Could it come from batteries charged by PV? Sure, but right now that's way more expensive than running a gas-fired plant.35% of our EV utility customers here in San Diego have PV solar...
4.5 kWh of electricity to refine a gallon of gasoline is not correct. On average it's less than 0.2 kWh of electricity per gallon. A little over 95% of the 5-6 kWh of energy used to refine a gallon of gasoline is thermal energy produced from burning petroleum byproducts made in the refinery (mostly) and burning natural gas (to a somewhat lesser extent). Less than 5% of the energy used in oil refineries is electricity. There's a discussion on this subject on TMC starting here
Also, it's common for oil refineries to have Cogen plants to make their own electricity.

Doesn't matter. That's energy burned that could have otherwise been turning a generator and putting kWh on the grid. Cogen or not, you have to include all of those kWh.

Hydro-electric power, which provides a substantial majority of the power produced in Canada and a less substantial (but still significant) portion of the power in the US plus pumped storage and demand management systems provide low cost storage and buffering of power and enable renewable energy to be utilized as and when available.But I guess in the spirit of this thread, it still counts. Because the original poster's question included generating capacity, and the PV generation shifts around the peak loads that in turn require less peak capacity.
Hydro is very important in some parts of the US, but negligible in others; e.g. it's nearly 20% in Alaska but less than 0.1% in New Jersey. So, it will have an uneven capacity to serve as the balancing power supply. Overall, conventional hydro accounted for 6.6% of US electric generation (MWh) and 6.9% of installed capacity (MW). There's an additional 1.8% of capacity as pumped storage. Keep in mind, though, that a lot of hydro is "run of river" and has no storage capacity. Other hydro has limited pondage, enough to be good intra-day but not enough to carry much energy from one week to the next. All hydro systems have operational requirements ("minimum flow") as well.Hydro-electric power, which provides a substantial majority of the power produced in Canada and a less substantial (but still significant) portion of the power in the US plus pumped storage and demand management systems provide low cost storage and buffering of power and enable renewable energy to be utilized as and when available.
if oil isnt required, the dedicated powerplants that run oil refineries can more than handle the load for EVs
take a good look at this video
also take a look at this link to see where your country fits in

This video is very well done - I like the animation, but the claim made at minute 3:16, that 4.5 kwh of electricity is required to refine a gallon of gas, is evidently not correct:
Where will we get ALL that electricity whan most cars are electric? - Page 4
Your second link is interesting. It shows that in 2005 the amount of electricity used per capita by by refineries in the US was 165kwh. If that number is correct, it would be enough electrical energy for each citizen to drive around 412 miles in the Model S (using 400 kwh/mile, assuming 20% charging and vampire losses). While not negligible, this is obviously not enough to power our transportation system.
Yes, there's a difference between the energy required to refine gasoline and the electricity required.This video is very well done - I like the animation, but the claim made at minute 3:16, that 4.5 kwh of electricity is required to refine a gallon of gas, is evidently not correct:
