Is the €30 usage fee going directly to the producer of electricity, or is part of it a variable transmission fee that goes to the network operator?
My monthly electricity bill in Sweden, averaged over a year to 1600KWh/month, is approximately €90 production, €50 transmission fee, €25 fixed connection-size fee (25A, 400V), €70 national electricity tax and €50 VAT for a total of €285/month.
We'll be moved to yearly-peak-based transmission tariff in 2027 (European law), but for now I don't need to worry about plugging in the car to chargeon cold days or taking shower when someone is cooking.
Both, currently; notably it's mostly not what goes to your local grid, but rather mostly to the larger scale grid.
It's about a 60/40 to 70/30 split between production/"grid-usage-fee" ("Netznutzungsentgelt").
It basically pays off the grid stability provision bids for fast-response power, and the transmission itself.
It'd likely be helpful if the peak part could be regulated in a way that's more condusive to match the actual impact you create on transformer sizing, not the worst-case impact you might have.
Because there's a difference between a mostly-uncorrelated peak of shower+cooking vs. the car+cold day, because your neighbours don't shower the same time, but the several hours of charging do often overlap and the cold is the same across a neighbourhood that shares a local substation.
But yeah, for the most part, transformer size isn't that large of a contributor to overall electricity provision expenses, so I don't expect that to be a significant problem by that 2027 law.
I don't feel that AQI in reasonably normal ranges corresponds at all to the subjective experience of how nice the air feels to breathe.
The best breathing I've done was in Mumbai. Felt like a silk blanket both in the lungs and on the skin. I'm sure it would be bad for me if I stayed there a few decades, but it didnt feel bad at all when visiting.
Are you from Mumbai? or a place with notably bad AQI? Do you smoke?
Mumbai is one of the most polluted cities on earth, many people report being unable to perform aerobic exercise or describe breathing the air as being similar to smoking.
I'm from a place with excellent AQI (semi-rural Sweden). I do not smoke. I usually don't mind when other people smoke, but I don't like how they smell just after finishing. :-)
I know that the Mumbai air is not healthy, but my subjective experience of it was very positive.
That is the last 2.7 patch from PSF. Other reputable organizations keep making new patch releases for as long as there are paying customers. Not just the big legacy distros.
I pulled into a Supercharger with my LFP-battery EV last winter. The temperature outside was -15C and I had not set the navigator so there was no pre-warming activated.
By the time I had finished my coffe, SoC had gone from 30-ish to 90-ish percent.
LFP tech anno 2023 is perfectly good enough for road tripping in large cars in severe winter conditions. For almost everyone.
So your battery was preheated. I once did the same with approx 0C battery temperature and whole ordeal took at least 2x longer. Yes there was farmers market in front of charge station so I had a good time with kiddo. That’s not the point.
Let’s not pretend better batteries shouldn’t exist.
Which doesn’t matter if your about to charge either way and just want to optimize time spent?
This can’t be more than single digit days per year? This is the case where people in for example Sweden have 230V engine block and passenger compartment heaters for their car.
It’s -30C and the heat pump doesn’t really work. Is there any advantage to heating the cold side with, say, a resistive heater?
Conservation of energy says no, but what if it’s also being heated by waste heat from charging the batteries?
(Maybe the answer is “if that’s the case, you are actively cooling the batteries with the heat pump!”, but I’d like to think someone more clever than me could make the scheme work.)
Quoting Bender from Futurama: "Great is OK, but amazing would be great."
I'm not against further progress, I'm just stating that using current gen LFP in cold climate for large cars driving long distances is not a problem. It is more than fine. At least Tesla's implementation of LFP, I can't speak to any others on the market.
I know of a few of highly custom enterprise systems. I still do a fair amount of consulting hours on 2.7 codebases. There is no technical reason why they couldn't be migrated, it just economics (or vendor management with incentives to not make it happen). The systems get to age out and are replaced with something else or rewritten from scratch.
Official EoL from the Python foundation was back in 2020, but the vendors providing Extended Lifecycle Support are still putting out regular patch releases.
ActiveState puts their releases on GitHub. Look around and you can find similar from RedHat (RHEL7 ELS), TuxCare etc.
If you still got Python 2.7 apps on production, you don't need to be stuck on old operating systems and using a base Python with known vulnerabilities.
Yeah, because a car has tens of thousands of parts that age with both time and usage. The core drivetrain is just a tiny bit of that.
Everything is falling apart and that makes and old, used car... Used and old. Now queue the people who show up to say they haven't changed a tire or wind screen wiper blade on their 2012 Model S/Camry and can't perceive a single difference to when they were new from factory.
They lower the prices a lot when they are producing at full tilt. This means that prices, at least to some degree, go up when wind turbines are not producing at full capacity, since the other power sources need to amortize their fixed costs across fewer kilowatt hours sold.
Going up or down: there is more supply, so prices go down wrt. a situation without wind turbines, at least momentarily until the wind drops down indeed when we go back to a system w/o wind.
If you can store the energy, your energy cost goes down (but storage is not free of course, though getting cheaper).
Amortizing the fixed cost will mean the 'fossil' power is more expensive per kWh indeed, making it more and more attractive to buy storage as to bridge the gap between windy/sunny periods that do have cheaper electricity.
Some electricity markets have or a re looking at capacity mechanisms, they pay simply to have the capacity to generate power at any given time, even if not generating, eg. to be a backup. Eventually, that will be the business case for any fuel-powered power plant I suppose
