It's easier to set up back yard solar panels than a back yard fuel refinery.

It is easier and cheaper to keep 100 litres of gasoline for emergency which would allow to drive at least 1000 KM.

Though probably unwise (and possibly illegal) in many cases.

'backyard' Solar panels won't recharge an EV

They can, actually. I'm not sure where you're getting your info from, but you can buy home solar panels from Tesla that can easily recharge an EV.

Needs 7-9 panels approx 5ft x 3ft. A roof array might work but a backyard is ambitious unless you're on flat land and facing south west

One thing I keep getting tripped up on with EV cars is the usability during an emergency. I grew up in SoCal when there were rolling black-outs. Just this week, a windstorm took out my parent’s power for 3 days. I don’t view electricity to be as reliable as gas. What fact am I missing that can change my view on this?

I have an EV. After I drive it home, I plug it in. Except when I'm lazy, it's basically never below a couple hundred miles of range remaining. Rolling blackouts wouldn't really cause an issue, and when I've experienced blackouts, it's never been a problem. When the power is on, the car would charge back to the limit I set (I usually keep it at 80% charged to preserve the battery, which is still nearly 250 miles of ra…

Agree with all that. And there’s also charging at work, for some people.

And some people live a block or less from a free charger so no waiting around really.

We have a solar array on the roof. It’s great. But the dc->ac converter needs the grid to be active to do its conversion, so when the power goes out no solar. (I suspect it syncs with the grids 60hz...) If you include a battery backup in your system, you can run without grid power. When I worked at a power monitoring start up we had a demo house that was charging an electric rav4, so it’s possible.

I understand why grid-tied systems are built this way, but from an engineering standpoint this is really inefficient. Converting from DC to AC and back to DC, for no reason. In fact, most solar controllers are already designed to use and charge batteries.

It doesn't help that most car manufacturers use locked battery charging protocols that don't allow you to easily change this process.

I'm more worried about range of EVs and charging stations being absolutely swamped in times of crisis. Gas stations lines were bad enough during hurricane evacuations, imagine roadside charging stations. I think I will always hold onto a reliable ICE car for the rest of my days.

Every building on the grid is a potential charging station. Even when gas stations are locked down.

I have lived in SoCal for 22 adult years. I’ve lost power maybe 3 times, and for at most 6 hours. A Tesla should have enough range for a few days commute w/out recharge. I don’t think power reliability should be a concern... except for when the big one strikes. But in that case all the freeway overpasses will collapse, so an ICE car won’t help you anyway.

Wait really? I live in NorCal, I lost power twice last week. That was unusual, but PG&E's safety outages are a fact of life of living in California. That said I also remember a hurricane (Harvey?) which shut down refineries, making gasoline scarce. So it's pick your poison.

A fact of life in the past couple of years only. It's a(n over)reaction to their legal woes, and I suspect it will snap back as regulators crack down on these actions.

I am going to buy a new car soon and I think it will be the last time gasoline will be available for me. I'm going 4x4 so there's not much EV options.

Are you claiming that EVs don’t have AWD? My car begs to differ. Or...? Sorry I’m not versed on the finer points of 4x4 versus 4WD versus AWD terminology so maybe it’s me that’s confused, feel free to fill me in.

Do you not travel and or enjoy road trips fairly frequently where you must re-fuel? I personally do(southern PA to central/Northern New York)! Also, can I charge a Nissan Leaf and or Chevy Volt using all the Telsa charging stations? IF I can great if not still these cars aren't for me or people who enjoy frequent road trips. Especially those who expect the same UX as a gas car. In time sure, but not there yet!

Central PA to northern New York is no big deal with the super charger network, I’ve done drives of that length. Tesla has offered access to their superchargers, but legacy car companies haven’t taken them up on the offer. Day to day, Tesla’s are better than gas - you don’t have to deal with filling up ever or oil changes etc. Mid range road trips like you describe are also easy. Super long cross country trips are doa…

> Tesla has offered access to their superchargers, but legacy car companies haven’t taken them up on the offer

Probably because Tesla demanded something that they knew other manufacturers won't give them.

They pulled the same PR stunt when they offered their pretty limited patent pool in exchange for all patents of the partaking manufacturers. Nobody wanted to take part because as a result Tesla would have had access to all patents while the others would only have had access to Tesla's patents. A pretty bad deal for everybody except Tesla.

In the Miami area after Hurricane Irma in 2017, we couldn’t find gas for our cars for about a week. I think the pumps for gas stations require electricity (which was also out) plus deliveries were disrupted by downed trees, traffic signal outages, etc. Just an anecdote that gasoline is not always available during crises. We did have electricity at home but neighboring buildings and neighborhoods had outages for a wee…

But it's not uncommon for people to have at least a gallon of gas stored in a typical suburban home. That's 20-30 miles of emergency travel if needed. I don't think most people can easily store enough electricity to give them 20-30 miles of EV range. Maybe that's possible with a powerwall type setup?

I'd be happy to pick up a cheap(The math may change as gas prices spike over the next year. I think that will really drive EV adoption. Time will tell though. So far, I see EVs appealing to a certain type of consumer(pro-technology and/or affluent).
