I know, stupid question... but I assume the transformer simply steps down the voltage to 220 / whatever amperage for the individual homes?
Makes sense that each home should / would need their own.
In that neighborhood, all the lines were buried as well, but the box behind my house was bigger. I'd say about 3 feet tall, and actually... probably a perfect 3'x3'x3' cube. My parents home in Northern Virginia (where I went to high school) also had one in the backyard. Exact same size, looked exactly the same as well.
My house in South Florida has one as well, but it's across the street in the front yard on the easement. None of my neighbors on the cul-de-sac have one, so if I count the houses... that's 9 homes on the cul-de-sac. So I suspect all 9 homes are fed by that one transformer in the front. They've worked on it a couple of times when I was living there.

Good info.
There are other things to consider as well, primarily probably revolving around when to charge, peak hours, etc.
Then also little things like infrastructure above and beyond just overall grid capacity, to include the end user interfaces. Interesting note "The worlds power generation" does leave a lot of room for interpretation. Id bet some countries would more than need to double. Another note, I'd bet there isnt much chance we can double our output by focusing on just solar and wind.

Just look at California...
Had problems getting power even before State kill most power plants.
Can't build enough solar or wind and whatever type "battery set" to start to replace them.
Now Gets huge amount of power from other states. (States that won't extra power because hell bent to green them too.)
And high volt lines are often at max power and start forest fires. Even when those lines aren't the cause, forest fires and more often make them to turn off.
So most of the state has huge problems w/ Blackouts and worse Brownouts and only gets Worse.
If you have Brownouts, you need to shut everything off and fast or except ruin AC Refers and a lot more. Can cause fires as motors etc fry because is same thing covered in cave for car w/ low volts. (Cave, Electric Motors)
You should turn off everything for Blackouts too but far less risk if Blackout happens and no-one around.
Is Part of Why Tesla and other companies are or have move out of Ca. Blackouts + Sky High cost when power is on drives many business to move alone. Couple that w/ High Taxes etc and people still wonder they move...
Other places in the US have power problems too and why can't get factories and other things needing a lot of Power and/or Nat Gas 24/7/365.
They make a lot of noise about "power walls" including giant "grid grade" units like done in Australia but is a thimble full of 500 gl or bigger tank that factories needed for a few hours or minutes even seconds when solar wind etc is down for any reason.

Not to mention that coal and oil fired power plants around the country are currently being vilified. The only way I can see us able to convert to primarily electric transportation (and also meet overall carbon dioxide emission reduction goals) anytime soon is to have more nuclear plants and those don't get built overnight. For instance, the two newest nuclear plants in the country began operations in 2016 and 1996. In fact, the average age of the existing nuclear plants in this country (which produce around 20% of the nation's electricity currently) is somewhere around 35 years old.
However, California (which the current admin wants the entire country to basically emulate policy wise) is planning to shut down it's lone nuclear plant by 2025 (https://www.pge.com/en_US/safety/how-the-system-works/diablo-canyon-power-plant/diablo-canyon-power-plant/diablo-dec ommissioning.page) even though it supplies around 10% of the state's electricity.

Yep. Thats how a certain political slant... and the media... do things. Make villains, rule out facts and common sense, promote emotions.

Speaking of nuclear power . . .
