Blackouts already cause major disruptions, even with the entire country depending on gasoline for their travel.
Yes, and the more people rely solely on electricity, the more disruptive it will be.
OTOH, EVs can be quite helpful in a blackout, as you can use your car to power necessities in your home while the power is out. A 70kWh battery in a car can power a home for two normal days (using electricity normally, not trying to conserve). If you limit what you are spending power on (as I would likely need to, since the EV6 will only supply 3.6 kW), it will last even longer. But even just with the EV6, you can power your refrigerator, heater, lights, etc. -- the things you would need to comfortably survive a blackout. This video talks of getting 5 days of backup power from the Ioniq 5 (the Hyundai sibling to the EV6, with the same drivetrain and battery system).
This all assumes that your EV is charged at the beginning of the blackout. Better hope the blackout doesn't happen right when you get home from a trip before you've had time to re-charge! I know, I know. That's just an "edge case".
Granted, you could buy a generator but that is an extra cost and, to ensure it will run when needed, you need to have a regular maintenance plan to keep it free of leaves and other debris, regular oil changes (regardless if it is used), test/replace the gasoline as it will go bad if it sits too long, etc.
I have a small portable generator and a transfer switch. When the power goes out, I simply roll it out of the garage, plug into the outside plug, flip the transfer switch and go on with my day. The generator is garage-kept when not in use, and the maintenance is pretty minimal.
I'm sure you'll try to object that you won't have advance warning and the EV may not be charged;
It's like you're clairvoyant.
again, you start the day with an EV at a high charging state (even if that is 80%). For most owners, even if they drive it all day (assuming an evening blackout), they still likely have 50% or so left (this will vary per individual -- though some may be higher if they charge at work. The car system also has a limit, which you as the owner set, to ensure your battery is not drained too low. Of course, for most people, once power is back you disconnect the house from the car and then plug the car in to the charger.
Story time: Last year, there were some very high winds that took out hundreds of power lines and poles all over the Northeast. I lost power on Saturday afternoon and did not get it back until late Tuesday night. I was one of the lucky ones. Many around here were without power for over a week.
An EV might have helped them for the first day or two, but then they would have been out of luck. I guess they could have made a run on the 3 charging stations we have here in town to juice up, but then, they probably weren't working either (since the power was out). OTOH, I just went about 500 ft to the nearest gas station and filed up a 5 gallon gas can. Pulled the cord and voila! instant power. When the tank ran out, I just filled it up again.
If the only energy resource you have is electricity and there is no electricity for an extended period of time, you're in trouble. The batteries will discharge and there will be no way to recharge them.
Since even experts (those who dabble in the gas and oil futures markets) don't agree, and are often wrong, I don't think either of us know, either, so I don't know what you are trying to argue here.
The point is that EVs require more per unit (kWh) than ICE vehicles do per unit (gallons) which means that even small changes in electricity price means big impacts in charging costs.
FTR, First Energy has said that "significant reductions" are on the way in our electric rates this summer. I have no idea what that means, but it would certainly change the calculus on my earlier example. Although I suspect I'd still be looking at a multi-year ROI on gas savings.
I already said we'd need more public chargers. At the same time, I don't think we'll need as many fast chargers, as what you are thinking, or public chargers. First, for those in apartments, what will likely happen is that landlords will need to start offering charging for tenants (assuming the apartment has a parking lot for tenants). These won't be public but private chargers, much like some businesses have for employees today, and likely have some type of security to ensure only the tenant uses the charger.
You think landlords are just going to eat the cost of installing EV chargers for their tenants? Not likely.
Yes, in cities where there is "row housing" there will likely be public L2 chargers on the street -- what I've seen is charging outlets that look similar to parking meters.
These are all wonderful plans. Let's talk again when they materialize.
Why would you need to wait an hour to charge "in an emergency?" You start every morning with 80%, you drive your 30 mile per day average (or whatever it is), leaving you over 70% if there is an "emergency" to get out of the area.
I know you're stuck on "averages", but you need to understand that your idealized world doesn't exist for everyone in every scenario.
(The following scenario is based on real life events)
Let's say I have an EV and I have to drive to Pittsburgh. That is about 160 miles round trip for me. And then when I get home that evening, something unexpected happens and I need to take my kid to the ER. But I wouldn't have enough charge to get to the hospital. We've already determined that an hour on a level 2 charger will net me about 44 miles. So, I guess I would just have to plug in and wait an extra hour (or more) before going to the ER.
EVs require advanced planning. You've talked about that at length in this thread. But not everything in life is planned, and if something happens that you didn't plan for, you might just find yourself unable to react quickly. OTOH, I can hop in my ICE car and stop at a gas station, even if I'm running on fumes, and go wherever I need to after just a few short minutes of fueling.
I know you'll just dismiss this an "edge case", but it's a very real scenario.
No, you are acting as if the rental agencies in Maui are all trying to rent out EVs
You're just making stuff up now. I've never said anything remotely resembling this.
