Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Doesn't give the best reason clearly. Lighter vehicles need less battery weight to get a target range and get more range per kwh/kg, which also means more range per charging time. Batteries are the most expensive part of an EV, and smaller means better car performance.

[–] HeroHelck@lemm.ee 30 points 2 days ago (3 children)

Correct me if I'm wrong, but isn't part of the problem that the auto industry wants to chase the higher profit margins on larger vehicles? As long as the perverse incentive is present it's going to be an uphill battle to get them to produce more compact, cost effective cars.

[–] shalafi@lemmy.world 8 points 2 days ago

EPA rules also play a part. Why we can't have small trucks:

[–] silence7@slrpnk.net 7 points 2 days ago

That's exactly the problem — in the US there's an extra tariff on larger vehicles, so the manufacturers face less competition and therefore earn greater profits if they only make big vehicles.

[–] cmhe@lemmy.world 2 points 1 day ago

An argument I heard was that larger and luxurious cars finance the technology development necessary to produce more economic cars. Which I guess is true to some extend.

But there are also many other aspects that favor large and expensive cars over cheap and economic. We still should demand tighter regulations on cars.

[–] dharmacurious@slrpnk.net 20 points 2 days ago (1 children)

Honestly, I live in a mostly rural area. It's 40 miles to the biggest large town/city, I'm 15 minutes to a grocery store. I'm lucky to work from home, but before that, I worked 20 minutes away. Even something with only an 80 mile range would do what I need it to do, so long as I can charge in public. I wouldn't like having that range, but I'd take it. IF IT DIDN'T COST AS MUCH AS A SHITTY HOUSE. Seriously, give us some cheap EVs that people can upgrade from later on and sell in the secondary market so poor folk like me can buy the equivalent of 98 Toyota Corolla.

[–] Mr_Blott@feddit.uk 5 points 1 day ago (2 children)

I'm up in the mountains and remote too.

Just picked up a secondhand Dacia Spring with a still-200km range for 8k €

Perhaps the problem isn't that you can't get the cars, perhaps it's that you think cars have to be big

[–] kent_eh@lemmy.ca 3 points 1 day ago

I don't believe I have ever seen a Dacia on the road in North America.

The options to buy a smaller EV are extremely limited here.

[–] dharmacurious@slrpnk.net 4 points 1 day ago (1 children)

Nope. I happily drove a geo metro, and I longed for a smart car for year. That particular vehicle isn't available in the US, either. But thanks for the assumption!

[–] dharmacurious@slrpnk.net 2 points 1 day ago (1 children)

I'm gonna go ahead and apologize for being snippy. I had just woken up, and I've got a fever. Think I misread your intent a bit.

[–] Mr_Blott@feddit.uk 2 points 1 day ago (1 children)

I wasn't clear either, sorry. Pretty sure Dacia is part of the Stellantis group of greedy cunts and therefore Dacia would be very much available if there was a market for it where you are

But no, tiny-penis trucks abound!

[–] dharmacurious@slrpnk.net 1 points 1 day ago

Look at us, being all nice to each other and understanding and shit! The fediverse really does bring out the best in us reddit expats, doesn't it?

And yeah, nah. Giant ass trucks abound for sure. A big part of that is our stupid ass laws, but also there's absolutely a culture of it. I drive the smallest truck we could find, a Nissan frontier, and the year model I have is twice the size of the one from a decade prior. It's insane. But we had to have either a truck or van to transport my mom's power wheelchair, and the vans are just simply so far outside our price range as to not even be worth considering. Even second hand. Hell, I found several with no motors in them that were still far too expensive.

Omg warn a person they might actually orgasm looking at that car! God that is sexy. Of course, it’s very expensive and won’t ever be “affordable,” but I would buy one immediately if I could justify that cash on a vehicle.

I’m a bit faint now.

Right. $50kUSD for what is essentially a go cart with no airbags and a manual retractable fabric roof and paper clip roll bar.

Realistically, the original Mazda Miata is a safer car with more features. It would fit perfectly into my mid-life crisis by sitting in my apartment carport collecting dust because I can’t afford the insurance on this gorgeous death trap.

But… let’s touch it again with our eyes:

Yes, lots of “inspiration” there. ;)

Thank you. At last something that makes sense to me in this discourse.

[–] Bitswap@lemmy.world 1 points 1 day ago (3 children)

I don't see anyone talking about the significant cost to upgrade homes to allow for charging. I am going to buy a bolt, but I need to save an extra 6k to upgrade my panel, service and have a circuit put in. On top of that, the soonest I can get the work done is 10-12 weeks out.

[–] theoli@startrek.website 4 points 1 day ago (1 children)

There is a lot of addressable market that can add chargers inexpensively. But I get that doesn't mean much to anyone in a 70 year old home with a full panel, all electric appliances, and 2 AWG cable buried in the yard.

To try to save some money, make sure you really need the 40 amp charger circuit and make sure your panel really needs the upgrade. I don't want to imply that you are getting into $6k of work without thinking very hard, but here's some thoughts and observations, just in case your electrician didn't suggest all this.

Tandem breakers can be used to move two single-pole circuits into one breaker slot. Doing this with four circuits can free up space for a double. Also check on how much peak load you are actually pulling, then figure on how many reactive starting loads are realistically going to happen at once (like AC coming on). I have the 40 amp charger circuit, a 50 amp hot tub circuit, a dozen servers pulling ~7 amps all day, and two air conditioners (main 40 amp and garage mini-split 15 amp). My peak 1 minute load is like 59 amps while charging the car. All that said, if you have electric baseboard heat in your home that can be a lot tighter of a squeeze.

I have had the EV for two years and I also find that a 240v 15 amp charger circuit, 12 amp max charge would have been perfectly fine for me. That would allow recovery of about 60 miles overnight, or ~90 miles in a typical commute-to-commute time-span of 14 hours. That's with a big chonky Nissan Ariya, the Bolt will do better.

[–] Bitswap@lemmy.world 3 points 8 hours ago

My understanding is that post NEC 2023 tandem breakers will not meet code. Yes, you can still buy them and yes I could put them in without people knowing..but that's not the way I do upgrades. You can still buy quad breakers but I don't think those ever met code.

Thanks for the info. I likely could be fine with a 20a/240v circuit...but i don't even have that available currently. I'll do some more research on the tandem breakers.

[–] xav@programming.dev 2 points 1 day ago (1 children)

What the hell are you talking about ? I did it myself for 400€ in less than an hour.

Don't install a super fast charger at home. It's a) useless and b) not good for your EV's batteries. Install a 32a charger.

[–] Bitswap@lemmy.world 2 points 1 day ago* (last edited 1 day ago) (1 children)

In the US we have building codes, permits, and inspections. While possible to upgrade the service to your house as a home owner it cannot be done quickly. It would be at least 2+ days with the power out if you can line up the power company and inspector properly.

I am only going to install a 32A charger. I need more service to my house to support it, 100A currently. I need a larger panel as I have no breaker space and I need the new circuit run ~150 ft away.

Please don't burn down your neighbors house. Less than an hour sounds like you cut corners.

Also, it's insane to say it's useless. Do you even know what that word means?

[–] xav@programming.dev 0 points 1 day ago (1 children)

In France we have building codes and permits and inspection. But no permit needed for such a small operation, and you can use your electrical installation while you wait for the inspection (that may never come).

There are 2 devices to install and wire inside the electrical board, how long should that take without cutting corners ?

Also sorry for the choice of word but that's what I think it is when doing something that goes against you're best interest.

[–] Bitswap@lemmy.world 2 points 8 hours ago

I see you didn't really read what I wrote and are just talking about running a new circuit. That is one of the 3 upgrades I need.

A panel upgrade is not a small operation and I highly doubt anyone could do it in under an hour. A panel upgrade consists of removing all breakers from the panel, disconnecting all wires, disconnecting all conduits from the panel pulling all wires out of the panel, (in my case enlarging the hole in the wall for the new panel), reinserting all wires, attaching conduit, redoing internal panel wiring, and putting breakers back in.

I've done plenty of basic electrical work. Electrical work is not complex, it just takes the knowledge of what is to code and if there are specialty codes for the state, county and/or city. I do not have time to study all the code and plan the upgrade.

Future proofing upgrades is very much in my interest. If I have to touch something or upgrade something...its going to be overdesigned/overbuilt because I don't ever want to have to touch it again.

[–] Nomecks@lemmy.ca 1 points 1 day ago (1 children)

Just stop by a fast charger every now and then. Some EVs will already charge like 80% in under 15 minutes. The next few years will see even faster charging. Might not be a need to upgrade.

[–] Bitswap@lemmy.world 1 points 8 hours ago

Chevy bolts do not charge as fast as others...but it's more about having the time to go to a fast charger. Of the places i frequent for groceries, etc. None of them have charging stations. Between work and little kids, doesn't leave alot of time for errands.

[–] JeeBaiChow@lemmy.world 4 points 1 day ago (1 children)

The Japanese should sell electric KEI cars. Perfect for small runabouts, just make sure the interior also holds up.

[–] Enceladus@lemmy.ca 2 points 1 day ago (1 children)

The KEI cars by design don't fit all safety and environmental ratings at higher speed the consumers cars have to adhere to in North America.

They exist as a very specific portion of the automotive market created in Japan by legal limitations that defines their profiles and capacities for taxes purposes. The fact that KEI trucks can be imported is actually a lack of extended regulations to farm equipment in the US.

The North American automotive market has no monetary or legal incentives to sell even inspired KEI cars since they are to cheap to make a reasonable margin and no tax loophole exist to prop up the industry.

[–] turmacar@lemmy.world 5 points 1 day ago

Are you conflating the chicken tax and the 25 year rule for imports?

My Kei truck is licensed as a "non-highway vehicle" in WA. Not using it as farm equipment at all.

Agreed that the US doesn't have the equivalent incentives that made the KEI category a thing in the first place in Japan.

[–] Hirom@beehaw.org 1 points 1 day ago

Harder, Better, Greener, Smaller

[–] reddig33@lemmy.world 5 points 2 days ago

Smaller cars need a good balance of range and charging speed. It’s fine if the car only goes 150 miles to the charge if it can recharge to full in 20 minutes.

Past compact EVs have gone around 80 to 100 and only come with slow charging. That’s not going to cut it anymore.
