Adding extra electricity consumption means in short run burning more coal and gas. They are the ones that can be ramped up / ran more hours.
I think that’s only gas plants, that can react dynamically to changes in the grid?
I think what we need is consumer electronics that can tolerate more variation in the grid power supply - e.g. a laundry machine that runs on 80% voltage just as well, but then takes a bit longer to finish.
Nuclear power plants are only preferable to burning fossil fuels, and only when run by responsible entities (i.e. not by humans ;) - definitely not by profit-oriented corps) - I hope we can transition to enough wind, water & solar power, but we definitely need to cut down on energy consumption.
As I was saying in my first comment: If energy is produced by renewable sources, then they can be clean, so there’s no argument here.

Finally, like I asked another commenter: could you provide a source on EV batteries made without rare earths?
By the way - sodium requires salt, and that’s also limited on Earth. Knowing mankind, we’d extract locally (desalinification hurts the ecosystem there) and dump waste locally in another location (again, hurting the ecosystem).
My overall point is: the world’s car market is just too big and we need to shrink it, but mankind as a whole is too fucking selfish and stupid and short-sighted to accomplish that, and I WISH time will prove me wrong on that.
Solar panels need to run for a couple of years before they produce net energy considering the energy invested into production
Source on battery production being less reliant on rare earths?
Speak English, please - I am not looking up abbreviations to argue with you
See my other reply here: https://lemmy.world/comment/12349903 Efficiency of an electrical car is better, but absolutely not “incredibly” better, as per the numbers I checked while writing that comment
How much cleaner EVs are, depends on the source of energy mix (which at charging stations outside your home, you can hardly control) - if renewable energies are used, they are certainly cleaner. If fossil fuels are used, they are at best (not counting the waste from battery production and disposal) as much cleaner as the efficiency improvement (which is about 40% over Diesel engines, by what I calculated from sources that were acceptably credible for writing an internet comment as opposed to a scientific paper)
I was not speaking about “mineral” resources, I was speaking about mineable rare earths. Because there are plenty in the Earth’s mantle, but we can’t get to those.
Again, source please on how EVs do not need rare earths for batteries
Agreed for the time being, but if research allows to improve the process for generation of hydrogen, it could be a cleaner combustion fuel
In summary: I am not arguing for combustion cars, I am arguing against EVs not for individual use cases, but as a “this solves all problems with combustion engines” - because it is not a solution applicable to the world market for personal mobility.
The best solution is a proper public transportation system - good bus connections and trains that can operate “by wire” without the need for batteries.
First things first: Yours is a straw-man argument. I said that electric cars are not “green energy” because it matters how the energy is produced. You, however, argue for the better efficieny vs. combustion engines. I did not even MENTION combustion engines. So watch your tone, dumbass :p /s
Regarding your straw-man, I’ll bite:
Efficiency of an electric car is up to 65% including losses when charging. Efficiency of a Diesel powered car is up to 45%. Producing a liter of diesel costs about 1.13 times as much energy as is contained in a liter of Diesel fuel, which - even assuming 100% efficiency on winning that energy - is further bringing down the efficiency to 45% * (1 / 2.13 ) = 21% (one unit gained per 2.13 units invested). A coal power plant is at best reaching 45% energy efficiency, bringing the overall efficiency of an electric car down to 65% * 45% = 29.3%. That makes an electric car operating on coal generated electricity about 29.3% / 21% = 1.395 or about 40% more efficient than a Diesel powered car.
And this does NOT include that electrical vehicles are - due to the weight of batteries - around 50% heavier than combustion engine cars, and that battery life is much shorter and then generates a lot of electronic waste.
Accordingly:
The dirtiest, least efficient coal power plant is still IMMENSELY more efficient than a car combustion engine
Not true. Numbers for the most efficient coal power plants are just about equal with the efficiency of the best Diesel engines. But even moderate Diesel engines stay around 40% efficiency, whereas coal plants can be in the 30%-40% range easily.
When you don’t have to make your energy generating device mobile, you can get a LOT more power from your fuel.
While - all things considered (I honestly did not expect the production of Diesel to be quite so energy-inefficient) - electric cars fare better if driven at constant speed (or with good energy recuperation mechanisms on braking) and not taking into account the battery life, energy investment into that and chemical waste produced on production / disposal, they are far from getting “a LOT more power” from an “IMMENSELY more efficient” power plant.
Maybe spend some time learning about a subject before you make claims about it. There’s less chance of looking like an ignorant fool that way.
Likewise.
There are a lot of reasons WHY news agencies disproportunatly show the downsides of green energy
Electric cars are not “green energy” - that’s utter bullshit.
the energy consumption of electric cars is about as clean as the power plant that produced said energy - if that happens to be a fossil fuel plant, it’s dirty as fuck, just with the pollution in a different location from where the car is driving If you have renewable energy, then yes, they can be cleaner, but:
we don’t have enough (mineable) rare earths to replace even a sizeable fraction of the world’s car market with electric vehicles
*nucular. It’s (pronounced) nucular :D
Because the amount of organizations needing data backups / protection far exceeds the amount of available qualified IT personnel. So instead of training themselves, they hire morons who say “sure I can do your IT”
german people have large privacy and date security fears. This has kept them off of many other platforms. Most people in my friends circle never had a MySpace / Facebook… Being in an anonymous space like here is nice.
While this is true for me(*) - partially, it’s not a fear, it’s a certainty that my data is not secure anywhere online - I would be positively surprised (but kind of doubt that) if younger people actually think consciously about their online privacy.
* never had myspace, deleted all my facebook posts, comments, contacts & then account in 2012 when they changed the terms & conditions to own everything you upload - and before then I had never used my real last name there
Thank you for the summary! I found myself in OP. I am eating mostly vegan, and I have a cat, and I believe people who force a vegan (or even vegetarian) diet on their cats need mental help.
Importing CSV into SQL is trivial and gives you far more control than Excel can.
But, if you’re a power user doing a lot of complex data analytics, Excel is still the king.
Only if you refuse to learn SQL and do everything in a fraction of the time with way more functionality.
That’s a cuttlefish though, and despite the name is not a fish.
Don’t waste my time with your bigotry and shortsighted dumb comments.
Palestinians don’t accept that the borders change and still want all of Israel.
“Palestinians” here is a useless generalization, because it lacks a quantifier. Certainly some do, and just as certainly not all do.
You underestimate the amount of brainwashing going on. When two people brought up in entirely different parts of the world, all other circumstances identical, are exposed to two completely different systems - they can often believe opposite things to be true, despite no person being intrinsically more or less good or bad than the other.
Also, generalization is a BIG problem the moment you use it as prejudice against individuals before knowing them. As a matter of fact, judging individuals based on generalizations is - the moment the generalization is applied to an ethnicity - equal to racism.
I meant that thanks to abstract art we’re willing to forgive “image glitches” in art by deep learning models.
Generative AI is much better at art than coding.
Mostly because humans invented this convenient thing called abstract art - and since then tolerates pretty much everything that looks “strange” as art. Must have been a deep learning advocate with a time machine who came up with abstract art.
Clearest difference I can see is:
In other words: A high profile person in tech being threatened with arrest / being arrested by western countries is a pretty good sign that they were not cooperating with our totalitarian overlords & providing us with ways to preserve our privacy.
When will a responsible politician be tried for murder? I know - never. But they should be. Because this shit is premeditated and with malicious, despicable intent.
