Electrotech is electric devices like EVs and heat pumps. For the first time, they are now more efficient, better, and lower-cost than their fossil fuel competitors (eg ICE cars, furnaces and AC units)
AC units are heat pumps
yeah AC units aren’t a fossil fuel tech lol
can we get some citations all these dudes is just say ai over and over, where are the energy density papers
Sorry actual research and data collection of material reality is too inefficient, so we outsourced all our analytical capabilities to a Fisher Price See 'n Say.
Okay but how does that work? I have a “fossil fuel” car that is paid for. If I buy an EV, now I have a car payment I can’t afford, and when that car gets paid off, it’s time for a new battery — which is basically gonna mean car payments for life.
Is recharging them free? I was never quite clear on that. I mean where are you saving money if you’re making car payments in perpetuity?

When your current ICE vehicle ceases functioning, you’ll need to purchase a new vehicle. It is now more both more affordable and environmentally sound for that purchase to be an EV.

To recharge the vehicle’s battery, you will need to plug it into an electrical receptacle. You will need to pay for the electricity used to charge the battery. This is less expensive than refueling an ICE vehicle.
I hope this helps!

Not if Sam Altman has anything to say about it!
Being facetious does nothing, really. You need to compare the whole energy chain from mining to use. It’s a very simplistic view that isn’t really right.
You need to compare energy density per kg of fuel source, efficiency of motor using said fuel, weight, use case, parts availability, etc. There’s a whole heap youve left behind in your effort to be a smartass.
It’s pretty hard for an EV to come off worse in emissions than an ICE vehicle. Not impossible, but difficult.
People who believe this are buying into misinformation spread by the fossil fuel lobby. Mining for battery components (primarily lithium) has far less environmental impact than petroleum extraction- at every step of the process. And there are overblown fears about battery life when they will typically outlast a combustion engine car’s usable life. Plus lithium is recyclable whereas a combustion engine will continue burning more fuel.

Sorry for not posting a dissertation in response to a tremendously stupid question. “Why would I buy a new car? It costs money! Does fuel cost money? I don’t have money!” is not something that requires a thorough response.

I sure hope every home is built with a garage, and/or has actual infrastructure built out for that to be viable… oh right, it’s not like that (I live in this little thing that everyone loves to conveniently fucking forget about, rural america), and I certainly don’t have any faith that it would even come anywhere close to that in within the next several decades.
Rural America is going to have no trouble finding space to put 240v chargers, rural America has more space than it knows what to do with. For most of the people I know living in rural America adding something to their breaker box is childsplay
I don’t have a carport or garage, I literally have a cord that comes off the side of my house and I park right there and get charged, wake up to a full battery every day.
It costs less the $1,000 to add charging infrastructure to a house. If you can park in the dirt next to the house you can charge, even better if you have a driveway or gravel.
Given the political climate, you should have clarified that ICE doesn’t mean border patrol in this context, but rather Internal Combustion Engine. I haven’t finished my first cup of coffee yet, and I had to think for a second.
Anyway, vehicles don’t just up and quit. They can break down for a variety of reasons but can generally be repaired. However, batteries are a consumable resource. My battery might cost $200 to replace. An EV’s battery is much bigger, and might cost $20,000 to replace. Of course it’s going to last longer, but over time its capacity will diminish and eventually it will need to be replaced. At that point it might be more economical to buy a brand new EV, because like with any other vehicle, you don’t know what else is going wrong with it.
I’ve been driving EVs for 10 years, there’s quite a few across my family. I don’t think we’ve sold a single one we’ve bought and they all still have their original battery packs.
I’m pretty sure the idea that the batteries need constant replacing is FUD. An ICE vehicle is going to need an engine/transmission replacement faster than an EV will need a battery swap
It’s also worth pointing out the cost of replacement battery packs has dramatically decreased over the past decade
I’m sure there’s some FUD there too. I mean it sure sounds like it, right?
But batteries are consumable products, and they do go out.
I want to like EVs and I believe they are good for the environment. I also cannot afford one.
They do go out, yeah. So do internal combustion engines and apparently at about the same rate. Literally nothing lasts forever. I’m actually not a huge electric car fan - they’re super inadequate and are just kicking the can down the road, what we need is to massively reduce our car dependency. But there’s no need to buy into this sort of outright disinformation.
Batteries do go out but it’s something like less than 2.5% of EVs made since 2011 have needed a battery replacement. If you only count EVs made after 2015 it’s less than 1%. All the early models before 2015 were pretty terrible with no thermal management systems on the batteries. Unless you are shopping for a gen1 Nissan LEAF with 43 miles of useable range you will almost certainly not have to worry about battery replacement.
From my observations a modern EV battery will usually last at least 150-300k miles.

At some point you will need to buy another car. EVs are increasingly cheaper than their competitors. Modern batteries will last longer than the rest of the vehicle.
Recharging them is cheaper than paying for fuel, most of the time.
You will be making car payments in perpetuity regardless.
