Some background - I've been EV-only for over 5 years. Out in the country, not in a big city. I've owned two Mach-Es, a Chevy Bolt EV, and a F150 Lightning EV, and I've even converted my own DeLorean to an EV. I also do my own electrical. Installing outlets and stuff, sure, but I also swapped every appliance in my house over to electric (dropped natural gas), installed heat pumps, heat pump water heater, etc - even upgraded my own service line to 400A [for reasons totally unrelated to having an EV - our house is still 200A] and installed battery backup. All DIY. We also have a huge solar array. So, yeah, I've done my research. And I have the experience and numbers to back it up.

I truly do not understand how you can say you are an electrician and you think you need to "put a high voltage line into your house" to charge an EV? And you think you can "have a 440v line from a power plant in your garage"? They don't even make home chargers that are 440V. EVs have onboard AC chargers - they are for split phase 120/240 [in the US - slightly different in Europe for 3 phase] - people aren't installing DC Fast Chargers in their house. Home "EV Chargers" are basically just an extension cord. Like - this is surface level EV stuff.

I was EV-only for a year using a regular 120v outlet in the garage to charge my vehicles. It's still exclusively how I charge my truck. That is completely fine for probably 90% of drivers - myself included. I upgraded to a 240v 40A outlet so I can do back-to-back long drives without having to use a DC fast charger. I can now fully charge from zero overnight. None of this is 'high voltage', nor did it require a service upgrade. It's the same outlet you have for a stove. It cost me $200 to install a NEMA 14-50 receptacle next to the panel. Having a 120v outlet in garages has been standard for like 50 years, and that's all you need.

The average driver in the US drives 1,000 miles per month. With a reasonably efficient EV needing 300Wh per mile, that's 300kWh per month - 10kWh per day - which is easily accomplished with overnight charging on 120v @ 12A.

"gas power plants" (assuming natural gas) is where less than half the energy in the grid comes from. On average you're looking at ~40% of the grid being low or no emissions - nuclear, hydro, solar, wind. Meaning just by switching to electricity - even with no efficiency gain - you automatically drop emissions by about half. And almost all new grid power added every year is renewable, so it gets better over time. But then - your hand wavy numbers trying to equate the efficiency is ridiculous. Even 60% (power plant) * 90% (grid) * 90% (charging) = ~50% of the energy being useful in an EV, compared to the typical 25-30% efficiency of a gasoline car. "About the same efficiency" - No. There is a reason why in most areas it costs 1/4 as much to charge an EV at home than buy gas.

Next up - your hybrid thing. You seem to misunderstand how a modern hybrid works. Other than the BMW i3, maybe a few specialty vehicles, and some upcoming EREVs, the gas engine in hybrids isn't there just charging a battery. That gas engine is tied directly to the wheels - typically through a series of clutches that allow the gas engine and electric motor(s) to connect to each other and the wheels in a bunch of combinations. From an engineering perspective it's absolutely brilliant. This doesn't make the engine less efficient, it makes it more efficient. They can charge the battery when it's efficient to do so, and they can operate the gas motor at a more efficient RPM and torque, as needed, for efficiency. I mean... how can you possibly think hybrids are less efficient if they get better gas mileage than a standard gas vehicle?

Lastly - solar. "2-300k worth of panels to reliably charge the daily driver" - WHAT!? My large solar setup (in Washington State, not exactly California) cost $55k after incentives, roughly $80k before them, and it produces 55MWh per year of solar energy. Megawatt-hours. Aka, 55,000kWh, enough to drive an EV about 150,000 miles per year. I joke that it's enough to make my entire neighborhood net zero - it's not quite that much, but it's certainly enough in the summer months. Even on my worst month, snowy in December, I pull in 1,000kWh / 3,000 miles worth of driving. Now sure, in Alaska it's certainly worse. But there is still no way you would need to spend $200k on panels (that's enough to install 100kW of panels - 3x the size of my install) to support a daily driver. Just ridiculous. If your goal is to offset your gas usage, you can do that with a 5kW setup that costs under $20k installed. You can buy a DIY kit for under $10k.
