I know you love electric vehicles. You let me know when one has the range to save me time on long trips and I’m all in.
do you see the car next to my name? It’s certainly not electric and drinks mostly E85. My daily is a gas guzzling GX. I do not love electric cars. But, since I know them and understand them better than basically anyone here through my work with Tesla. I simply come to shoot down the asinine talking points brought up here.

If you go ev, then it is best to invest in solar. Tesla system with Powerwall is optimized to charge a Tesla vehicle.
Solar is always a solid investment if you have favorable irradiance. But I wouldn't use PW juice to charge because you’ll lose some efficiency. It’s still better than nothing but the best thing to do if you have solar is DC charge during the day.
But in general the solar + storage is an awesome setup. We run a 40kW system with 4 PW2s at my wife’s ranch. Been off grid for weeks at a time with no issues.

I almost did this but the ROI was yelling in my ear and did not pull the trigger.
When I was in Cali a few weeks ago I drove a full sized hybrid and was vv impressed with the milage.

The ROI is precarious once you throw 28k in batteries on top of the solar. I got lucky and not only got a smoking deal on the PWs but also the electric company to let me go much bigger on the PV than the typical consumption that put be at about 300% offset. That much net metering moved it to about a 10 year payback that will most likely be much shorter with current and future energy inflation.

If you have an EV on a full charge prior to hurricane, youd tend to have around 200 mile range, some could be up to 300, some lower, but I think 200 is safe. Id find it rare that someone would drive 200 miles and not have access to some charging either because you drove away from the hardest hit areas or you drove a few miles each day and the power was restored by the time you needed it.
Also, do you all ever get tired of being afraid of evs?

yeah I remember your original post on this. The quotes I got was w/ 2 batteries to power the AC unit. I have been eye balling Ecoflow batteries tho for a smaller solution.
The end result of my analysis on this was if the main goal is power outage due to an event that solar solution does not work and I would spend less on a whole home gas.

The infrastructure isn’t here yet for EV. Biden is a fricking idiot.
Just a side note, xiDung is NOT running this crap-show.
Most of the id-jiots calling the shots in the WH are nothing more than pointy-headed academics who know absolutely ZERO about the economy or energy policy other than failed utopian wishes they read from some commie POS university.
We are having brown-outs RIGHT now all over the country. They are shutting down nuclear power plants and coal as well.
It takes years and years just to get permits to construct new power plants and then at another 10 years to build a new power plant.
Then look at all the power lines and basic infrastructure, transformers, millions of homes will have to be retro-fitted with 220 volt outlets which will run into a few thousand $$ per house-hold.
To even get to 1/10th of powering EVs, we are going to need lots and lots of new power generating plants which will take decades.
A simple internet search turned up these numbers:
quote:
There are 276 million vehicles registered in the U.S. as of 2019. This includes 156 million trucks, 108 million cars, 8.5 million motorcycles, and 575 thousand buses.
Even if we went 10% EVs, i.e. 27,000,000 vehicles(that's 27 million), the generating power is NOWHERE near what will be needed.
Now throw in trains, boats, tractors and other farm equipment, those huge mega-cargo ships that transport in goods from overseas...
I am all for advancing technology and EV tech seems to be progressing along nicely.
But think of this, it took over 100 years to build the infrastructure necessary for the 'ICE' economy.
Its gonna take decades to get to even 10% of a EV economy.

During the evacuation for Katrina it was not the distance that was the issue, it was the gridlock. People got trapped on highways, not moving , and unable to exit. So many people were running out of gas that fuel trucks were sent along evacuation routes.

I hear you but that is a terribly rare example where ICE engines were an issue as well.

The point is we xsn both list issues but they are more outliers than anything

Electric vehicles by Dixienourmous69
I am watching the Ole Miss- USM game and just saw an electric car commercial and a thought popped into my head. How would someone charge their electric vehicle after a hurricane and the power is out for at-least a week if they do not have a big enough generator?

Even if we went 10% EVs, i.e. 27,000,000 vehicles(that's 27 million), the generating power is NOWHERE near what will be needed.
The average vehicle drives 15k miles per year, which takes roughly 5,000 kWh of power to charge. 5k kWh times 27 million is 135 Billion kWh, or 135 terrawatt-hours. That represents less than a 3% increase over our current annual consumption of 5,000 TWh. That sounds pretty do-able, doesn't it? Especially given that peak consumption is during the day while EV charging happens mostly at night, we have ample excess capacity during off-peak hours to fill with EV charging.

I could just put the gasoline in my truck and go to work. While you’re hoping that you bought enough gasoline to run your generator long enough to charge your car. This is a silly argument.

Furthermore, I’m not saying that electric cars can’t be the future. I’m just saying that they are not the solution for the present problem.

quote:It's only silly because it's a contrived extreme weather event scenario. It's an argument against the idea that an EV would be useless, and a solid one. An EV really has more utility than a gas vehicle in these scenarios because it's a large portable supply of power. If you have an EV with 110v outlets you can probably keep your fridge and a window unit running through just about any lengthy power outage.

quote:If by "the present problem" you mean as in OP's hurricane example, then I would argue that those affected would be better served by an EV than with a gas vehicle. Gas stations tend to start drying up days before a hurricane due to a run on the pumps, and it can be scarce for a while after it comes through. As I believe I mentioned a page back, there are no fewer than 20 natural gas generators in my neighborhood (I have one), which means I would always have a place to charge near my home. I imagine most neighborhoods in south LA are similar. There are zero scenarios where an EV would be unable to charge up. There just aren't. You can go on about charge times all you want, but the fact is almost every vehicle is parked 95% of the time, and most of those times there will be a receptacle nearby. And again, it's easy to find one on a generator when the grid is down.

Baw, I would happily drive an EV- if it could provide me the same reliability, in all conditions, that a gasoline engine does. You and I are pawns, in a chess game between the existing powers and the challengers thereof. While I admire your forward thinking- I will use what works best for me. And, until they make affordable work trucks that can go the distance required, without having to plug it into a fossil fuel powered electrical system, I will continue to put the fossil fuel in my truck.

This board struggles with that. A farmer or police officer would be inhibited by an EV at this point. I drove about 10k miles per year so it would be a savings for me. People need to evaluate their lives and let others do the same.
