The reason for gas in the US is because people like it. It's been seen as upscale for decades to have a gas cooktop. It also helps that gas water heaters don't require electricity and work in an outage. Our residential natural gas distribution network is extensive and reliable, and it's pretty straightforward to use the same appliances on propane for people out in the sticks.
Things like lightbulbs and TVs and computers and refrigerators are using less power than ever before.
Of course, if people are buying electric cars or replacing gas furnaces with electric heat pumps, then you're right on that side of things.
Are they, though?
Lightbulbs, sure, we won with LEDs.
But TVs, especially the huge, high brightness ones we have nowadays? And with the extra computing needed?
Computers, same, I only see power usage going up. I mean PCs, we're not comparing things with mainframes here :-)
Refrigerators: are they really more efficient?
Now add: heat pump, induction stove, electric oven, more powerful AC, humidifiers/dehumidifiers, etc.
And compared to the age of the Pentium 4 with its 100W+ TDP, laptops now outsell desktop computers by a long way.
(I would agree that things like high-end gaming GPUs are using more power than ever before - but they're also a much smaller % of sales than ever before)
According to the internet a CRT TV used to use about 100W, while a big LCD TV can use more.
Regarding desktops, don't forget that these days we have many more electronic device in a home. Smart speakers, home media devices, consoles, etc, etc. Electronics probably use, in aggregate 5-10x what the old family PC used to use, I'd imagine.
To change my gas stove/oven back to 240v induction would be a 15 foot run of romex, a new outlet, and probably an updated circuit breaker. Possible for a DIYer to do.
Older houses might have a dedicated 240 plug for the dryer and the stove if they're not natural gass, but for everything else there are plenty of homes full of ungrounded 10 amp 120v circuits.
And yeah, my house is full of 120V circuits, but once again the house has 240V at the panel and could run 240V anywhere in the house if needed. As you pointed out, they probably do have a 240V plug for the dryer, ergo they've got 240V service at the property, so they could wire the kitchen if there's no wiring already. Once again, practically nobody has only 120V service at their home.

Largely they have the same power output. While the total power available is actually higher for the US version at 12kW versus 11.1 kW for the UK version. That is because the US version needs to be on a 50 amp 240v circuit versus the max 16 amp circuit for the UK version.
Even this Bosch one: https://www.bosch-home.co.uk/product-list/cooking-baking/hob... Which clearly calls out 400v 3 phase has a lower power output at 7.4 kW.
Are they, though? With modern appliances, power requirements are going up and 110V is struggling to keep up. One example would be an induction hob.
I know that technically US homes can access 230V but they aren't wired for that, probably 99% are wired just for 110V except for maybe a few special lines.
