It is one of those basic question related to energy consumption versus energy produced. I think that you will find out that the current plan will fall short, well short, of demand.
I am not a genius. But is not a complicated question that the “geniuses” should be asking.
Thats actually not true. Gasoline is a stored energy. You can have a tank of gas in your car for a year and still start it up. The combustion engine cycle of a modern engine efficiency (conversion of heat to useful work) is about 70% as I recall from Mech engineering classes 40 years ago. The electric power grid does not store energy. It burns coal, gas, or some other combustible, or relies on hydro-electric or nuclear (which we dont build anymore) or unreliable wind, to generate current that is available for use right now, but not storable on the grid. (You can store some charge in large capacitors, buts thats more to smooth/regulate the voltage than to store energy)
The grid must have enough power to handle the consumer load at any given time. The efficiency of maintaining that available load capacity to charge an electric vehicle is not nearly as good as a simple can of gasoline.
This is why the all electric car pushed as 'green' is such a scam. Its really not saving energy. A hybrid makes a better case for efficiency, but is still very expensive and may never break even in costs.
The avg commute is 40 miles round trip per the NHTSA.gov data with fully two sigma of all trips not just commutes under 60 miles round trip. A model 3 would at normal not freezing temps use less than 10kWh to do a 40 mile round trip and as these guys proved and what is already well documented by tesla slightly more when cold. Since 80% of all Americans drive less than 40 miles per day using a model 3 sized EV would mean 10 kwh a day would be needed. That’s equal to running a 8kw cloths dryer for just over an hour a day or a normal sized AC unit for a single family home for and hour and half. Hardly grid crashing usage.
Virtually no one is going to fully charge a EV with a 300 mile range from zero to full every night NO ONE. Most people go to the petrol pump once a week or less. The ability to top up every night in your garage eliminates that need for an EV. The only time you need large amounts of power is road trips and that’s what the superchargers are for. There is a very small minority of people who drive 100s of miles per day, such as uber drivers or delivery services this is way less than 1% of all road traffic again the NHTSA has detailed data for those willing to look for it.The other group of high millage is rural commuters which again area tiny fraction of total drivers. The vast majority of road travel could be covered by EVs with not 300 miles range but 100 giving a two to one buffer of a 40 mile daily avg commute. Three solar panels above the garage would fuel that in most areas of the country south of the Mason Dixon line in latitude. Since most as in 80% drive just at 12,000 miles per year total a Model 3 sized EV would need 3000 kWh per year in energy to cover those 12,000 miles that’s 250 kWh per month. My home uses 3000+ kwh in a single month in August roaring the AC units at 67 degrees all day. 250kwh per month for the avg driver is not going to crash anything. At Texas power rates retail of 9cents kwh 250 kWh is $22.50 in electricity costs that’s less than a single tank of petrol for a similar sized vehicle one of my S60 takes 70 liters that’s 18 gallons for you yanks at 2.89 that I paid yesterday it was $52 to fill a tank that will only take that S60 510 miles at best. The model 3 will go 1000 miles in distance on $22.50 in electricity twice as far at half the energy cost.
