These folks claiming more fossil fuels will kill us all need to get a grasp of reality in my view.  The hyperbole just looks silly.

they need to do some research first and be able to back up their claims with something

everybody keeps pushing EVs and ignore the fact that the current energy sector could not support a large conversion to EVs

we better solve that issue before we drive everybody away from gasoline powered vehicles

Folks can push EVs all they want, the transition is going to be pretty slow.  You can't buy something that isn't there to buy.  And I think the electricity production issue will get resolved in most areas.  A lot of the EV demand would be at night.

the grid will evolve with demand

just as it has forever

yes and while its evolving which energy source will be used the most

wind?
solar?
natural gas?
nuclear?
oil?
coal?

right now Biden is doing everything possible to kill oil so which other energy source will be able to accomplish this "ramping up"

he's thinkin about loosenin up on offshore drilling

oil isn't dying because of Biden

IMO, he should be killin coal

We use very little oil to generate electricity.  We use a lot of NG though, which can be conflated.

The EIA shows solar making a large increment by 2050, NG will still be around.  I think I read solar doesn't do much at night though.

With some thought, we could replace coal with nuclear, but that would require actual thought.

think storage to be used at night and also think that less electricity is used at night

Solar could be the thing with a breakthrough or 3

There is a lot less demand at night, and solar would need some sort of storage to help.

Pumped water is one interesting option.  One article I read calculated the increase in demand from EVs will be similar to that caused by residential AC back in the day, fairly gradual and manageable.  Even if we see 100% of new vehicles being EVs in 2035, it's doing to take a while to put a dent in the fleet.

People have been waiting for 7 or 8 decades for a breakthrough in electrical storage.  There have been some interesting advances but compared to the types of titanic shifts we've seen in say... semiconductors... we're still basically at the point of sticking a couple of dissimilar metals into a potato and calling it a day.

I sat through a battery seminar a long while back.  The fellow showed some calculations about how much chemical energy could be stuffed into a small package that was impressive, it wasn't much before you run into some obvious problems.  Those electron thingees at some point can "achieve their potential" and jump through even very good insulators.

It was shocking and I was pretty amped up about it.  Some of my coworkers resisted understanding the basic problem though.

Carters Dam - Wikipedia

Below the dam is a 1,000-acre (400 ha) retention and re-regulation lake (Reregulation Reservoir). The hydroelectric plant is of the pumped storage type. That is, during off-peak hours the water from the retention lake is pumped back up to Carters Lake for use in generating power during the next time of peak demand. The dam's power station contains 2 × 140 megawatts (190,000 hp) Francis turbines and 2 × 160 MW Modified Francis pump turbines for used in pumped-storage.[3

Yeah I like this, very clever.  Obviously would work better in some regional locations than others, but the first time I heard of it back when, I was struck by how innovative it was.
