Yeah, our world is not efficient. Privatization and deregulation hasn't helped anyone but the rich. Back when this all happened we were a much more socialist nation, and things got done.
But this is the world we live in now. We can sit around and complain and stagnate... Or go out and keep pushing for progress. Buy that electric car. Upgrade that electric service to your home. Just like your grandpa or great grandpa did when he got his fancy new AC.

Nope, none of the current crop of EV's comes anywhere near meeting my requirements so I definitely will not be buying one, and I do not believe EV's are going to save the world, there is way more to this world than vehicles alone can fix.

And as far as your ASSertions about privatization, deregulation and socialism all I can say is wah wah wah.......

No one claims that EVs are the one and only solution to fixing human caused damage to the planet. They can definitely help but it’s only one part of a complex puzzle.

The OMG the grid is going to burn down types. Never as in never know their power usage vs what a EV uses on a typical EV use day. To add to that many of those same critics are what are called super commuters and drive well over 30 miles a day. I’m not talking about the farmer running field checks here. I’m talking about the critic who lives well over 30 miles from their daily office.

The typical EV conservatively gets 2 miles per kilowatt. The typical AC using home can easily burn through 60kilowatts in a 24hr cycle.

If you want to shout from the roof tops that the grid is going to melt shout at the 1000’s of people who choose to live in places that are otherwise uninhabitable without AC.

. . . Back when this all happened we were a much more socialist nation, and things got done.
We were a much more cooperative nation. Government and private industry worked together on big projects (e.g. government built the roads, industry built the vehicles and gas stations).

But this is the world we live in now . . . Or go out and keep pushing for progress.
But it needs to be progress rooted in reality. In my neighborhood (Southern Minnesota) we have regular brownouts whenever the heat index is above 85ºF. Relatives in Portland and Pasadena report the same.
The problem is the 'progress' is being driven by activists and activists always think in best case scenarios. We need an honest analysis of our electric grid in a realistic worst case scenario. Then we can start pushing for more demand.


Buy that electric car.
  • I can only afford 1 vehicle.
  • Current offerings do not meet my needs.
  • Couldn't afford one if they did.
Upgrade that electric service to your home.
Quite expensive. Checked when the house was built 30 years ago.

Just like your grandpa or great grandpa did when he got his fancy new AC.
Great Grandpa - no electricity, wood heat, animal powered farming; no AC.
Grandpa - sometime in the 80's, already in house in So.Cal.
Parents - got a window unit when they retired in 90s.
Me - finally got whole house air last year. don't tolerate heat as I age.

To replace electricity that is CURRENTLY generated by fossil fuels there needs to be 10X more electricity generated from renewable sources.

Nuclear is 20% of CURRENT US production. Renewable is 20% of CURRENT US production. 10X of 40% (or even 20%) would be way more electricity than we need, even if you assume that we need more production capacity to then store at times where renewable production is lower.


Additional power will be needed:
- to replace fossil fuels used for other power generation
- to stop developing nations from using fossil fuels
- to power machines for carbon capture in the airline & agriculture industries
- for carbon capture needed to lower CO emissions to a level (30 years ago) that will stop climate change


You're moving goalposts now, trying to bring in *international* electricity to justify your 10X number. Oh, and "capture carbon to lower emissions to a level that will stop climate change" when all you were originally talking about was powering EVs.

Stick to the original topic.

Do we need 10X renewables to power EVs in this country? Nope.



I suggest you talk to some people that have looked at installing EV chargers in existing buildings/homes.

I'll just talk to myself, I guess, since I've already done it. Cost $300. No issues whatsoever.

LoL shhhh his 220 dryer plug isn’t advertised as a EV charger. So the Electrician is trying to sell him a new $6000 dryer plug ??

It would work but running a cord down the stairs and out the garage door isn’t the most efficient way. They are also normally a 30 amp circuit so they will only provide half the charge rate of a hardwired charger or 3/4 the rate of a typical portable charger on a 50 amp circuit.

A dryer circuit in my state has been a 50amp by code since the 60’s. My EVs do about 30miles an hour charge on that.

You assume I was referring to the USA which I wasn't. Even if the USA manages to go 100% renewable (which it won't) it's not enough to change what's happening in the world.


You nailed it with "just talk to myself" that's the reason nothing is going to change.

I think one of the biggest reasons an ICE is not used to charge the batteries on a full EV is just the shear amount of power those vehicles use. I own a Rivian R1T and it has a 135Kwh battery in it. People don't understand just how much power that is. Sure I can literally plug it into a 110 outlet and I can get 1 mile an hour out of it charging and that is plugged directly into the wall. I could plug it into a generators 220 inverted outlet and maybe get to charge at 7Kwh which would get me about 13 to 15 miles an hour. That's a big generator to do that and you would use more power driving during that hour then that large generator could produce. In short you would never keep up. I believe the key here is two fold we need to develop a more robust DC fast charging network and second will just happen over time is better battery tech in 10 years battery tech will be way better than it is now.

On a side note I didn't by my Rivian to save the world I purchased it because it is **************

I disagree. The beauty of a range extender is that you could cut the battery size in half and still have a very functional range. So say we cut the Rivians 137 kwh battery in half to a 70 kwh battery. Its half the size and weight. 70 kwh is only equivalent to like 2 gallons of gasoline. To recharge that battery completely would only require like 5 gallons assuming the gas engine only had 40% thermal efficiency.

You could recharge that battery in about 1 hour running a 100 hp engine. Thats a large generator, but its very small as far as modern car engines go. You could do that with a 2 cylinder 1L turbo engine that is purpose built to operate at one load and ultra efficient.

The 1000 lbs of battery weigh you save is enough to cover the small engine and alternator and gasoline.

The only time you use that generator is if you exceed the 150 mile battery range you get from the smaller battery. That would cover 99% of peoples daily driving requirement and the ice would only need to jump in on longer trips or if you were to use a truck to tow more than 10 feet.

At the end of the day, the Rivian is a 7500 lb truck because it has like 2000 lbs of battery in it that achieve the same range as 10-15 gallons(60-90 lbs) of gasoline in a 5000 lb ice truck. Batteries suck at energy density. If you need sustained high output, gas/diesel is the only way.

The only way an EV truck will ever replace my ICE truck is if they somehow triple the battery range without making it 15000 lbs, or they add a range extender to make the towing range reasonable. Id love an EV truck but I need the truck to be able to tow more than 90 miles with a 2 hour charge time if I dont find a charge putting out 150 kw

You need to think bigger. Vehicles will become more specialized persay.

If you want a long distance tow rig the options will likely be very similar to the current hybrid F150 only in different load rated rigs 1/2 ton 3/4, 1 ton etc.

If you need a truck but don’t need to drag a trailer long distances full EV etc.

A very small % of vehicles travel long distances. Most vehicles only travel 30 miles a day or less average. So the Hybrids cinderella combo is EV power that gives smaller more fuel efficient engines power to do heavy work yet can just about cover the 30 mile ish daily average range in EV only mode etc. My heavy tow Expedition would see a 2-3x bump in average fuel mileage if it had this combo, yet I could still do long distance hauls with it.
