STANFORD, Calif. — Leaving your luxury electric car charging overnight to have it ready in the morning seems like a good idea in theory. But in reality, research suggests doing so does more harm in the long run. Stanford scientists say that it’s more costly to charge your electric car at night and it could stress out your local electric grid.
Instead, researchers suggest drivers should switch to charging their vehicle at work or in public charging stations. Another added benefit to charging in the daytime at a public station is that it reduces greenhouse gas emissions.
With the effects of climate change more apparent than ever—frequent forest fires, widespread flooding, and stronger hurricanes—car companies are expecting people to start investing in electric-powered cars in the future. For example, California residents are expected to buy more electric cars as the state is planning to ban sales of gasoline-powered cars and light trucks in 2035.
“We encourage policymakers to consider utility rates that encourage day charging and incentivize investment in charging infrastructure to shift drivers from home to work for charging,” says study’s co-senior author, Ram Rajagopal, an associate professor of civil and environmental engineering at Stanford University, in a statement.
So far, electric cars make up one million or 6% of automobile sales in California. The state’s goal is to increase that number to five million electric vehicles by 2030. However, the study authors say that the change from gas to electric will cause a strain in the electric grid when there’s 30% to 40% of cars on the road.

“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,” explains Siobhan Powell, a doctor of mechanical engineering and lead study author. “And it’s not just California and Western states. All states may need to rethink electricity pricing structures as their EV charging needs increase and their grid changes.”
If half of vehicles in the western United States are electric, the team estimates it would take over 5.4 gigawatts of energy storage—equivalent to five large nuclear power reactors—to charge the cars. However, if people charged their electric cars at work instead of home, the electric demand is expected to go down to 4.2 gigawatts.
California currently uses time-of-use rates to encourage people to use electricity at night such as running the dishwasher and charging cars. However, the authors argue that with growing demand of electric cars, this strategy is outdated and will soon incur high demand with low supply. More specifically, the teams says if a third of homes were to charge their electric cars at 11 PM or whenever electricity rates go down, the local grid would become unstable.
“The findings from this paper have two profound implications: the first is that the price signals are not aligned with what would be best for the grid – and for ratepayers. The second is that it calls for considering investments in a charging infrastructure for where people work,” says Ines Azevedo, associate professor of energy science and engineering and co-senior author.
“We need to move quickly toward decarbonizing the transportation sector, which accounts for the bulk of emissions in California,” Azevedo adds. “This work provides insight on how to get there. Let’s ensure that we pursue policies and investment strategies that allow us to do so in a way that is sustainable.”
The study is published in Nature Energy.
Co2 at 385ppm today is nothing compared to 2250 when dinosaurs lived and thrived on Earth.
Earth still went into an ice age that ended 11,000 years ago but had lasted at least 70,000 years with glaciers 2 miles high in where NYC is today and created the Hudson river basin .
The weather and climate is dictated by far more horrific events than man can induce .
Extraction of lithium is the most polluting act on Earth today as we use millions of gallons of acid on acres of Earth to leech the mineral out of the soil that is left toxic for thousands of years !
Going green with Electric battery cars is fiction for feel good programs sold to those who do not understand as the media has been controlled and not telling the truth of things including Corona virus.
We live in the 21st century yet knowledge has been replaced with fiction and now is the age of deception !
Do not pollute the Earth , that much can be fixed !
We pay two cents per mile and the price for our car was $35,000.
You will pay around $7 dollars a KW hour when they get rid of fossil fuels. An EV holds around 25KW hours. The 2 cents is to get the uneducated to buy into the dumb idea that EV’s are clean.
Correction! An EV can hold 60 to 200 KW hours. Multiple that by $7 dollars an hour.
Lucky. I rented a Tesla model 3 standard range for a two week trip I took earlier this year.
I added up all the miles I drove and divided that into what I paid for charging. Then I compared that to what I would have spent in gasoline for a similar car.
The Tesla 3 was about 40% cheaper. Somewhere around $0.20 per mile.
To be fair, this was in Miami traffic and I was using fast chargers, not home charging. Range from 100% to 20% was only around 70 miles. Usable range was 45-50 if you subtract the distance traveled to and from the chargers, which were rarely available near my destinations.
It was a fun experience, but I’ll definitely never rent another electric car if I know most of my driving will be in a dense urban area.
We just did a trip from ND to CO, 1620 miles, with all charging at superchargers. I figured the cost was 9 1/2 cents per mile. When I charge at home my cost is 3 cents per mile.
The trip to CO would have been about 16 cents per mile based on $3.69 per gallon gas.
I pay 13 cents per mile and the price for my car was $1,500
This has no factual basis whatsoever. Industry and offices works during the day. The grid typically goes to less than 30% of peak rate at night. Essentially, charging at home, at night, is the equivalent of running ones air conditioner at home. None of us have our power so strained that we couldn’t run a 2nd 240v unit at night – otherwise we would be out of code.
I think she sat at her desk and dreamed this up. Not an engineer, not a person who understands power distribution. Just a pawn in the game of public opinion. For shame!
Either it was her or the study authors, but the article was very naive about how electric utility grids operate. You are absolutely correct about the demand being significantly lower at night compared to day. Charging EVs overnight is actually an opportunity for utilities to better utilize their excess capacity at night. This article just mystifies me????
Thank you for that clarification
You’re ignorant.
How much does the petroleum industry pays for this propaganda? It’s always the non-ev driver who doesn’t want anyone to have one. Pay for gas and don’t complain about prices.
I charge with solar whenever I want to. No gas, No Electric bill, No pollution. There are a lot of studies and then there is the truth!
You can’t charge with solar if there is no sunshine. You depend on favorable weather conditions.
There’s this thing called ‘battery energy storage systems’ that every microgrid includes as part of their renewable energy plan.
People will continue to believe the “manmade warming” myth until they are found frozen to death in their homes due to forced energy rationing. The same people who do not know 90% of our grid power comes from natural gas, nuclear, and other non-renewable sources. No additional nuclear plants are planned, and there is no possibility of wind and solar filling a much greater demand once drivers are forced into an EV. Which means driving one’s own car will become a pastime of the wealthy and well-connected. Everyone else will walk, bike or take public transport.
You are just dead wrong. 43% of our power in the U.S. comes from non-carbon emitting sources.
19% Nuclear (stagnant growth)
12% Wind (growing rapidly)
8% Hydro (stagnant growth)
3% Solar PV Utility (growing rapidly)
1% Biomass (stagnant growth) >1% Geothermal (growing, but very small)
👍👍👍👍👍
Agree with you as your data is correct. These Glow Bull warming leftards are insane and being used by the greedy leftwing elites.
Data is wrong!
CO2 is now ,at least 415 ppm, up from less than 300 ppm 200 years ago. The increase is almost entirely attributable to human activity, primarily from combustion of fossil fuels. Dinosaurs died out 65 million years ago, humanity has been around for about 200,000 years, so the relevance of your comments is dubious.
Why does it matter
Made up data. There could’ve been no sensors back then or they could’ve been calibrated differently, if scientists had any, and other factors. Secondly, CO² ppm changes during the day and overnight. During pandemic when we barely had cars on the road you would think the CO² value would go down drastically, right? Wrong. Find sensors around big cities like San Jose or SF and check & compare the values during 2015-2021.
👍👍
Hundreds of millions of years separated the ice age you reference and dinosaurs. How exactly are they related?
James, dinosaurs are still roaming the Earth. You’re one of them.
“Extraction of lithium is the most polluting act on Earth today”
Nope. Lithium is not produced that way.
🤦♂️ I stopped at “Extraction of lithium is the most polluting act on Earth”.
Wow what a load of BS. Guess you are hoping no one will look up the facts… on the internet… that is at their fingertips… that they are reading that on. 😂🤣
It’s ok, you can hate EVs. Just stop spreading bullsh!t. Unless you want to look ignorant and or stupid. 🙄
How does charging at work or in a charging station reduce the risk to the power stations? The power in the local area comes from the same power station.
I think it’s because there’s plenty of solar and wind energy available during the day (or will be), and it actually gets wasted if demand is lower than the supply. But during the night, if demand keeps going up, there won’t be enough power (unless they increase the amount of natural gas used). Currently, with fairly low demand during the night, the power companies like being able to just keep their gas turbines running longer to meet that demand – I think it’s troublesome to shut some of them down at night and start them back up later – but at some point when the nightly demand is high enough, they won’t be able to meet it that way, or it won’t be cost effective. For the planet, the best approach is to get more and more energy from wind/solar/hydro (even nuclear), less from fossil fuels, and have the cars utilize the excess wind/solar energy that apparently is or will be available during the day.
“Going green with Electric battery cars is fiction for feel good programs sold to those who do not understand as the media has been controlled and not telling the truth of things including Corona virus.”
Why couldn’t you start with that? Then I wouldn’t have had to waste any time reading the rest of your comment.
This article goes against everything we hear about electric grids being overloaded during business workdays. In the summer, we are asked to scale back our daytime use of air conditioning and other electricity hogs. Many electric plans also offer cheaper electricity at night. So this article smells of misinformation.
Wow. Who would’ve thought.
Ha!!!! That is NOT how lithium is produced.
========================
Technologies used for producing lithium chemicals and lithium metal from mineral sources, salt lake, salar brines, saline water, etc., are reviewed in this chapter. Processes treating lithium-bearing hard rocks normally involve first thermal treatment of these rocks at high temperature, followed by water leaching to release lithium values into solution. When salt lake or salar brines are used to recover lithium, solar evaporation is commonly used to concentrate lithium and precipitate salts of major elements such as K, Na, Mg, Ca, etc. Leach liquors or concentrated brines are then further treated using precipitation, ion exchange, etc., to remove residual contaminants. Carbonation using soda ash or carbon dioxide is preferred to precipitate lithium carbonate as the final product whereas lithium hydroxide is frequently recovered via electrodialysis and crystallization. These products usually are of battery grade (99.5% purity) and could be further processed to produce high purity compounds (>99.9%) by redissolution, ion exchange, and reprecipitation steps. Salar brines are currently used as dominant feedstock for the production of lithium compounds around the world principally due to low operation cost and high reserves as compared to those from mineral sources.
Now electric cars are causing global warming so can’t charge at night during the day Maybe gas cars are not so bad you don’t need a wind turbinmade with 100 tons of coal to charge your battery
CO2 is over 500 PPM, james!
This article is so full of bs I could make a fortune bottling the methane back to you progressives as Chanel #5
Electric cars will never go beyond what they are today….a rich man’s toy.
Sure, and that contraption those Wright boys made will never catch on.
You’re only reinforcing his point. Less than 1% of the population has a pilot license. Even fewer own an airplane. Commercial air travel is still a luxury for most.
Yet to see one in everyone’s garage in the suburbs …
Gas cars are more expensive, but you keep pedaling that FUD.
Oil Shill.
Folliw the leftwing money, son!
Electric cars are bad for the environment ultimately…one still needs to use fossil fuels to make and charge the batteries. Wind turbines kill thousands of eagles and other birds, and then need to be repaired often and polute the ground when they need to be buried after a few years. Plus, they are not reliable, they need constant wind, and solar panels need sun. I am all for clean air, clean water, and conserving . But we need a sensible, balanced plan to provide power, which includes fossil fuels. Prove man made climate change please. Science is not a consensus. Thank you.
Why would a $20,000 car that gets around at 2 cents mile and has almost zero maintenence costs be “a rich man’s toy?”
Zero maintenance cost until you have to change the battery which costs more to replace than the value of the car. Or replace the engine with a used or rebuilt engine and save yourself tens of thousands of dollars…
Apparently you haven’t priced batteries, you just read the fake articles that are anti EV. 3 or 4k buys a replacement battery aftermarket, new in the box. Hopefully your car isn’t valued less than that.
Lithium Iron Phosphate batteries are being sold and deployed with estimated 300k to over 1 million miles of life expectancy. Over 50% of Tesla ship with Lithium Iron Phosphate. Look up CATL Lithium Iron Phosphate batteries.
$10000 is the max most families can handle, which means they can only afford to buy cars that are 7-10 years old. The batteries die after 7 years and cost $20k to replace, so there will be no one able to buy a used electric car. Until the battery replacement cost drops below 50% of the value of a 10 year old car, there’s no way the average family will be able to buy a working electric car. Ever. A year of daily uber will be cheaper than spending $20k on a battery.
If you can get an Uber in your town!
Cost will come down…be real.
It’s only a matter of time till rebuilt batteries will be on the market st substantially lower cost. Tesla model 3 will likely be first as more are on the road. Not much demand as of yet.
What the hell kind of EV are you buying with a battery that only lasts 7 years my dude? That’s how long our old Toyota ICE SUV lasted though.
Now I have a BMW i3 (pure EV model) I got used for cheap, and it is nearly 7 years old with basically zero maintenance history besides cosmetic parts (passenger handle came loose, some dents on trim, etc). It’s in flawless condition after that time.
Want to know what my battery degradation is? 0%. It isn’t lying or fudging the numbers, I really do get the full rated range in perfect conditions on 100% charge in the real world.
Battery tech has come a long way my friend. But manufacturing defects happen and yes there will be *exceptions to the rule* in specific EVs that have a battery up and die. Just like gas cars need full engine replacement sometimes but most never will.
Really really really believe you’re going to continue paying 2 cents a gallon.
Wake up you foolish human being!
Have you by any chance checked in the cost of batteries for ev …last I heard between 29, to 39 000.. so how can you say zero maintainable, it’s a battery, ya never know how long they will last , could be brand new and next day they are shit
$20K ? Really… more like $60K to $90K.
With a parking lots full of $50-75K Trucks, Mercedes, and BMWs this cost meme is BS. Bought my 1st EV used for $8500.
California must have a lot of rich people. Tesla’s model Y and model 3 were the top two vehicles sold there in the first half of 2022. Not the top two EVs – top two vehicles. More than any other car or pickup truck.
This is another leftist stupid ass lie. Hurricane were strong in past when we had less combustible engine on road. It’s all about controlling the masses with fear. What difference does it make if you charge on road or at home. Article is a joke
So if everyone switched to daytime charging. They’d have an even bigger problem. That’s when industry uses the most power and when the weather is the hottest and air conditioners run in offices and factories! So foolish!! Green is puke.
200% wright California hasn’t build a power Source for decades thank could use water generated generated generators but they don’t want to ruin their coastline they could use wind and water They don’t do decialization make they could use these things the better they’re people but what they choose to do is nothing nothing a binatural gas from other States that lmother’s dates the look green for their few fireplaces
Won’t work no Infrastructure employers are going to pay for charging your car at work as well that’s the highest demand for energy And most expensive time
Exactly! No that existing commercial buildings or apartments have chargers anyway. And if new build commercial and apartments installs them, have to secure it somehow, by pin login, something, so non-employees don’t use them and others don’t roll to apartments n use your charger.
Yes, and I doubt companies will be happy to be responsible for the higher electric bill so employees can charge their cars at work. Who thinks this is the reality most of us face? And charge at the gas station? Don’t some of these cars take up to six hours to charge?
Yes you are right about the usage I strongly believe that Joe Biden conducted this research
Exactly, The USA doesn’t have the infustructure to handle electric cars!
Yeah, this take is a bit on it’s head. Yes, it would be silly to insist that solar generated during the day needs enough stationary battery to time shift until nighttime for car charging.
But until charging capacity is installed to directly consume solar, overnight charging at home is the only thing that makes sense. Existing generating capacity would also love nothing better than nighttime load levelling
trump is the biggest lying con man grifter ever, anyone who is still supporting him is a gullible fool!!!
And you are a tool. Crawl back under your rock.
Mass formation psychosis anyone? EV(s) Study Finds just a ruse. However, if you wish to park a lithium ion battery in your garage, be my guest! You can’t fix stupid. Why doesn’t the media pimp CNG? 97% clean burning, abundant and cheap.
But not renewable or sustainable.
Not true, many landfills, dairys, sewage plants, etc all can pull methane for RNG. Able to be compressed on site for fuel, or pumped into the pipeline. Also the absolute cleanest currently available technology.
100% correct. These EV shills make no sense. Hurts environment to charge at home, but not anywhere else. Rofl. Oh and all they hype you will save money. Watch them increase all electric rates 24/7, plus charge you a per mile road tax. They need to track you for that last one. So many lies, so frequently and liberals still believe it. Poor things.
Fossil fuel shill.
Stop your asinine FUD.
I wish you eco terrorists would stop. You are morons, you cant think, you offer only objections and can not be reasoned with. Go away now.
Can The Electric Grid Handle EV Charging? – CleanTechnica
https://cleantechnica.com/2022/09/12/can-the-electric-grid-handle-ev-charging/
I think it’s opposite.
CNG has several problems one of which is energy density meaning you lose about 20% of your HP and the second problem is it has a shorter run window than even electric meaning you have to refill more often.
What this study doesn’t take into account is both batteries and large scale energy storage will be drastically improved over the next decade while things like Internal Combustion Engines and their fuel sources have already reached their peak and will not get any better. The single biggest factor is efficiency, and Internal Combustion Engine is only 20-25% efficient and that’s not going to get any better while it’s child’s play to make a 95+% efficient electric motor because all you need is two good bearings
Too many bought into the man made climate change lie. Climate change has been happening since the beginning of time. There’s proof going back 5000 years just by what crops were grown where by the decade. It’s always been about control, not the environment. And for all those bragging about low cost per mile just wait until they start taxing per mile to recover lost gas tax revenue. You’re tying your own noose.
Charging them at work presupposes that your employer is willing to front the costs of installing charging stations for each of its (EV owning) employees. It also ignores that typically, such ‘public’ stations are usually put in and managed by third party providers, who typically charge an upcharge amount per kwh for the convenience of using their stations. So it is most certainly not cheaper to the consumer to charge at a public station versus their home level 2 charger. Maybe its cheaper from a power company standpoint, but that is somewhat irrelevant to the consumer who is ultimately paying for it.
You are right.
This is turning into a boondogle. Before setting an arbitrary date to ban the sale of gasoline powered cars, it would be wise to upgrade the grid. This is going to take decades. We are headed for a monumental disaster.
This article is trash and is poorly sourced.
There is not an over abundance or power being generated during the day, which is why the Time Of Use rates are set as they are. There is not more wind and solar energy being used than what is being consumed during the day.
So, everyone should be charging at work? So we will have entire parking structures and parking lots reworked to have charging stations at each spot? I cannot even fathom the amount of power that would require at a single source, let alone the logistics to have that wired.
The other idea was to charge during the day at public chargers? So just take a 4 hour lunch to charge your EV?
I cannot believe that anyone took the time to produce this report without addressing the MASSIVE holes in how any of this would actually be executed.
She does not have the first clue.
Yes the writer of this article was a real lightweight I love it when she says when global warm is becoming more apparent and then she lists The usual suspects hurricanes forest fires drought but if you look into it all of it’s based on b*******.
Seems this article had a verb tense problem. You take a study on how much electricity cars well use in ten years, then conclude that the grid isn’t working correctly today. Pricing is currently higher during the day because demand is higher during the day. If and when peak demand hours change in the future, that will be the time to change when prices are highest.
100% agree. I’ve reached these topics and she is reporting the exact opposite of the facts. Read her background, it isn’t this.
As a transmission operator I can tell you that the hypothesis offered by the authors is completely wrong.
Thank you I thought it was sketchy myself.
This whole e car thing is a bad joke or a nightmare in the making. I know the goal is to eliminate private cars in the hands of the public and make us like North Korea.
When Battery Electric Vehicle (BEV) sales, including fleet & used vehicles, reach about 25% of the California market, owners of leased commercial property like large apartment buildings, neighborhood shopping centers & business parks will finally begin responding to market demand (& incentives?) to install vehicle-to-grid (V2G) chargers with integrated parking lot canopy solar & stationary battery storage. These relatively high power demand properties will become the hubs of 1 to 2 mile radius micro-grids networked across typical suburban neighborhoods. Good used PHEV & BEV vehicles will cost under $10k. Electrical consumers, including lots of hard working lower income folks, will become “Prosumers” instead of just passive consumers of power, and reap grid stabilizing service fees from their connected EV vehicles from 3pm to 10pm, at home &/or work. That’s how we get grid reliability & price stability with social equity to replace autocratic petro-states, BigOil & utility company monopolies. Think about how much reducing & stabilizing utility bills and transportation costs will benefit young families & everyone living on modest incomes. For a peek into the direction we’re headed, see:
https://cleantechnica.com/2022/06/27/virtual-power-plants-do-more-than-aggregate-they-empower/
https://www.pearlx.com/ and
https://www.nrel.gov/docs/fy17osti/69017.pdf
What type of happy seeds have you been ingesting? The direction were heading is going to be a disastrous dead end if this green energy foolishness does not cease. There are always those who try to tell the masses what they should do even though they have no idea of the consequences. Utopia in search of nirvana never sees the downside of the idiocy that is being proposed.
Happy seeds is an understatement. Forcing EV’s and all these climate policies will be a disaster to Mother Earth. First off batteries, motors etc require massive amounts of metals which when extracted will poison the water. As an example sulfuric acid used to process metals is an oil byproduct. Without oil it will be pumped out of the ground along with toxic metals. Of course this will be in 3rd world or dictatorship nations. I can go on and on here. The EV elite of course will ignore all this, drink their latte, and pat themselves on the shoulder how wonderful and smart they are.
Democrats do this each and every time. Push their agenda no matter what. Then when it all turns to 💩 , they’re like ” Gee, what happened?”
Under no other circumstances has humanity given up something essential (fossil fuels) prior to having a reliable replacement but that is what we are trying to do now with alternative fuels. It’s insanity.
Also, no one discusses all the other items we depend on that are manufactured using hydrocarbons from fossil fuels such as tires, just to name one.
Exactly-feedstocks for manufacturing chemicals is overlooked in most discussions – drives me nuts! The class of folks all in on BEV’s and are always knocking petroleum would probably contend we can make stuff from soybean oil or ear wax, but playing around with molecules to try to make them do what petroleum can do by nature will not go as smoothly as the green pack imagines. Or do they want to give up their plastics? I doubt it.
Exactly! Plastics from oil products are in everything. Parts for cars including EV, fashion people overfill their closets with, iPhone and all phones, take away food n beverage, on and on. Oil cannot be fully eliminated. Unless everyone is ready to go back to 1880s.
Lol. When the 70% that’s consumed in transportation is electrified, the remaining 30% can come from vegetable oil
Thank you! This is a accurate take on where we should go
So off-peak no longer means more generating capacity and lower costs, but instead less renewable capacity and higher costs. Rather hilarious, half the draw of an electric vehicle is the convenience of home charging; ripping that benefit out from under consumers, or even raising rates will leave quite the bad taste.
It might be cheaper for folks to charge their cars at night at home .find out what rate you pay for one thousand watts an hour. And if the rate is cheaper some where else near by your home.
A significant aspect of the forced shift to electric vehicles is the control over people that will shift to bureaucrats and government. Nobody wants to talk about or acknowledge that fact.
the government can tax gas so high that no one but them and the rich will have use of it and they can do the same with electric. It’s harder to tax walking though.
I love it when every left wing journalist slips in global warming as the cause of everything. Oh wait, they lost that argument and after going through global cooling, global warming and falling on their faces , they noe call it climate change. The problem is not due to the planets weather, it that there is not enough electricity to charge 10% of the number of cars now if they were electric. On top of that California will not approve any new power plants to be built.
Not have they built a single desalination plant to solve their ever worsening water problems. Not a single water collection and storage facility while millions of gallons of water to to waste. They’d rather spend billions of dollars on trains that no one will use.
There will never be enough sun our wind to power our needs. Not to mention all the mining of toxic materials required for solar panels and batteries.
And no one wants the whole landscape dotted with turbines either.
Wait, so now you can’t charge your EV at night, and you’re supposed to charge it during the day, to reduce greenhouse gases, when that was the whole point of the stupid thing in the first place, AND it takes 5 nuclear power plants worth of power to just be able to charge these machines at night, when electric demand should be at its minimum, despite the fact that wind and solar will never be able to produce energy at 1:1 rates with nuclear? Does anyone else see this massive con job for what it is?
Almost every statement in this article is false… This person has obviously never owned or charged an electric vehicle, and the study cited is (even though it technically supports the EV industry) is wrong on almost every point it makes. Most EV’s charge during “Super Off Peak” times, usually 11pm to 5am, when charging at home. Most superchargers (Tesla, at least) have solar panels and batteries. This article us just fear/uncertainty/doubt meant to make people wary of BEVs. Never forget the oil industry makes $20 billion per day right now. Every day they delay the inevitable is worth lying to you for. Think about that.
How did people charge the electric cars that existed in the early 20th century?
If it costs more for me to charge during the day, that is a no go.
And why are the utilities not trying to optimize for charging at home at night? Sounds like another PG&E scam to me.
Mike, Please stop blaming PG&E for Sacramentos failures.
This is not accurate math. The used electricity and demand during that period will be higher.
I was a chief engineer for a textile company in Virginia and was in charge of the utility bills/ demand/ consumption where I worked in Virginia. We would routinely get curtailment notices for electric usage during peak (working) hours. Our choices were either cut usage or pay a higher bill during those peak hours. We also experienced several outages due to blown transformers and inline fuses due to business use, which took down power to an entire business block for hours at a time. To give you an idea of our use; the electric bill we paid Dominion Power was $15,000 per month average, after our incentives. Some months were as low as $12,000 some as high as $20,000
My point being, most business use all the power the grid can supply during working hours. Plugging in several thousand cars will only exacerbate the situation.
Day charging at a public charging station may be good for California’s grid but it is hell on the consumers’ wallet.
How is it possible to save 20% electricity by charging in day time? The kw electric use for charging a given number of cars will remain the same no matter when charged, however the current electric grid is being used close to its limit in the day and electric capacity is not there to charge all those proposed electric vehicles in the day time. For example, California threatened blackouts in the daytime if people did not reduce usage this summer. And that is with a lot of electric car night charging and only 6% electric cars in California now, what will happen at 50% electric cars on the road (BTW the electric cars still need to pay usage milage road tax, and the electric car tax incentives need to go away if they are such a good idea, gas cars are paying at the pump with the gas tax). Without a TOTAL electric grid overhaul and upgrade, the convert to electric car mandate is not feasible. There is no way this can happen in 12 years since the current grid took over 100 years to make.
Generating capacity will have to increase and windmills and solar will not do it.
Any place that is decommissioning power plants without building new ones is only transferring their pollution somewhere else (yes, solar and wind pollute, there are different kinds of pollution , and kill wildlife, don’t believe me? do some research)
Everyone ready for HUGE electric rate hike to pay for the stupid politician mandates?
