Charging cars at home at night is not the way to go, study finds

Duke Energy is building a square mile 75 megawatt solar farm down the street from my house. It can never pay off but it will provide electricity in the event of an ‘event’.

As John Kerry-Heinz would say: “DUH”.

Gassing up an ICE car: 5 minutes. Ten if you use the bathroom.

Charging an EV at home "over night" = 8-12 hours.

Charging an EV at a 120kW "supercharger" station: 1/2 hour.

Charging an EV at a typical 50kW charging station: 1 hour.

[But these will greatly shorten the life of your EV's batteries, "totaling" the car when they need to be replaced. So, buy a new EV!]

[Physics is a bitch, ain't it?]

{Not to mention: What happens when 100s or 1,000s of EVs run out of juice between cities during a hurricane or other evacuation????}

[Osage Orange]

Totally agree.............

[Personally, I think that Greta Thunberg should be “renditioned” to Angola and forced to work with the other child laborers in a lithium mine.]

[Travis McGee]

How do you say “Solyndra” in Bidenese?

I wonder who is buying Gulfstream Vs and diesel megayachts with the govt-directed profits?

How are we different from Venezuela, other than in scale?

[Osage Orange]

I’ve seen that ski slope. Never understood it....in a middle of a desert. Fools and their money...About as foolish as Politicians here in the States.

[NorthMountain]

Why do you think I’m interested in seeing lithium batteries get recycled???

The mining process is atrocious, even at Mountain Pass. I know more about it than you think I do.

One look at the summer load curve of virtually ANY utility shows this study is complete BS. There was barely enough capacity to meet load in a LOT of parts of the country during the peak afternoon hours. Why would they want people to add the burden of charging cars at that time frame?

Much better to do so at night when the demand is less.

Now, come winter, those demand curves are significantly different, with very cold temperatures bringing in a demand that peaks in the first couple of hours of daylight as the need for heat is added to the normal load increases associated with people getting up to make coffee and such. So in that time frame, it might make sense to charge in the afternoon when the heating load is less, but before evening when the sun goes down and lighting/cooking demand rises again.

This is what REALLY galls me...

"We need to move quickly toward decarbonizing the transportation sector, which accounts for the bulk of emissions in California," Azevedo continued.

That ridiculous assertion is ALWAYS casually thrown out as fact. The student authors should go back to first principals and question that. Everything proceeds from the cultish, naive, child-like belief that that is true.

Most of Ohio’s electricity comes from coal, nuclear then NG.

I'm almost certain that natural gas has passed up Nuclear as a source in Ohio, and quite likely coal too. There are several newer combined-cycle gas-fired power plants scattered around the state, and I know that they've de-commissioned several coal-fired plants in that state (along with most every other state).

[Jacquerie]

ICE vehicles do not spontaneously combust.

Big diff.

But you know that.

"We were able to show that with less home charging and more daytime charging, the Western U.S. would need less generating capacity and storage, and it would not waste as much solar and wind power," said Powell, mechanical engineering Ph.D. '22.

It takes the same amount of electricity when ever you charge it. The laws of physics do not change with the clock.

[Travis McGee]

Reread 76. We totally agree.

[CodeToad]

We are now into total corruption. Lawlessness escalates.

[CodeToad]

An EV pollutes FAR more than ANY ICE vehicle on the road.

The experiment has already been run, under optimal conditions, and it failed.

The island of El Hierro, in the Spanish Canary Islands (as Spanish as Hawaii is American) has an abundance of:

1. Steady wind.
2. Full solar (latitude and weather)
3. “Gravity lakes” for pumping water uphill during peak wind/solar, and “harvesting” hydro energy by gravity off-peak.

There was probably no first-world, technological spot on the plant as perfect for a “sustainable green energy” experiment.

It failed. El Hierro still needs to import hydrocarbons. With literally everything going for it, max wind and solar, it could not run independently. El Hierro was probably as close to a perfect closed system experiment as we will ever find.

1kW/m²

At the top of the atmosphere. At the equator. At midday.

It gets worse from there ...

Some of the "renewables" crowd just don't get that.

They're the stupid ones.

Their leaders are perfectly well aware ... and that's the plan. They want us jammed into urban tenements, owning nothing and being miserable. Or just dead ...

They're the evil ones.

“Spain’s El Hierro island finishes 2019 with 54% renewables share”

[54%: with the maximum conceivable on earth wind/solar/gravity hydro power combination. Anywhere else will be FAR under 54% max renewables.]

They want us to live in fish aquariums, controlled by them. "Renewable and Sustainable! will be the boob-bait. Greta T. will be a leading advocate.

A "Line City" where, by "accident" (or on purpose) they can "forget" to keep the tank clean, or feed the fish, or keep it in the right temp range, etc.

"CONTROLLED BY AI! What could be better than that!
