> EV's for long trips aren't great. I have a Chevy Bolt 2023 EUV. Cross-state trips take 50% longer than a gas car.

I know it's a cop-out to blame your choice of vehicle for your experience, but please understand that the 2023 Bolt EUV has a max DCFC power of 55kw. That's about a third what the majority of vehicles are capable of (150kw peak) and about 30% less than what my 2020 Kona EV can pull (75kw) - another vehicle that was comparatively under powered when it was new.

Your 2023 Bolt EUV is literally the second worst charge-performing EV you can find in the US, with the #1 spot being the 2024 Fiat 500e.

I hope you're not too disillusioned with EVs because of it; the EUV is a perfectly fine vehicle for daily use especially for the price. Just know that your experience is not typical.

> I'm talking about load shifting, you're talking about base load and frequency maintenance.

And I'm saying you cannot effectively do load shifting without storage. Renewables tend to peak mid-day, especially solar, and the ability to soak up that surplus energy is dependent on actually having loads that can be dispatched at that time. We're talking about domestic energy use which is not very flexible; Okay great you can do your laundry with cheap solar electricity at 10AM but that's not helpful if you're not home at 10AM. There's very little a typical homeowner can do here unless they've invested in additional equipment. Storage batteries and water heaters are the most obvious choices and are easily scheduled to take advantage of electricity rates. Taking a half day off work to do all your household chores is a bit less practical.

> If I can shift enough of the load away from 7pm, then I don't have to turn on a coal plant in anticipation of base load need at 7pm.

That's exactly not how coal power works, and that's actually the core problem. You can't turn a coal plant on and off on a whim; it can take north of a full day to get one of those things started. This means you can't afford to turn off a coal plant from 10AM to 3PM when renewables are peaking because you won't be able to turn it back on in time for the 4PM peak demand. The coal plant stays on, and now you have to soak up the surplus energy to avoid blowing up the grid. In case you missed it, this is *exactly* the reasoning discussed in the article.

This is not about saving you, the consumer, money. If electricity is expensive to buy then that cost gets passed on to you. The only economic factor at play is the cost of curtailing renewables - curtailment also costs money and those costs CANNOT be passed on to the consumer. Utilities want to avoid curtailment and would rather give electricity away for free than absorb those costs. This point is, again, in the article.

To me the hoops that smoothbrains will jump through to avoid IPv6 and stay on legacy IPv4, especially when hosting, is pathetic. NAT, port forwarding, tunnels, blah blah blah blah.

I have something like ~1.2 trillion times the number of routable addresses that the entire IPv4 space has. Not all are reachable, of course, just the services that need incoming access and they're each on their own isolated DMZ.

Comment My home network is nearly pure IPv6 (Score 1) 73

Started the move about 18 months ago when I decided to get off my lazy ass. My ISP gives out a /56 prefix, so that lets me run 256 /64 subnets/VLANs in the house, currently there are ~10 in use. Everything get a GUA through SLAAC and I use RAs (Router Advertisements) to give ULAs to everything. Any external facing services get their own VLAN and /64 for the system(s) as needed. Firewall blocks all incoming as they usually do by default and I punch a hole for the external-facing systems. They can't reach back into the network, they only answer the phone. All the systems update DNS dynamically if the prefix or full address ever change.

I have an SSH bastion set up. In all this time there has not been a single SSH attempt from the internet. On IPv4 it was constant background noice.
For those legacy IPv4-only systems on the internet, I set up NAT64. I have an IoT VLAN and IoT 2.4 GHz wireless network that are only IPv4 because a lot of IoT network stacks are junk.

I'm still farting around with it, but man oh man, there's no way I'd go back to IPv4. It was one of the best moves I've done in ages.

Not exactly. Electricity must be consumed at the same time it's generated, and the stability of the grid hinges on supply and demand being balanced. Load shifting requires storage, which there isn't enough of, so using electricity now usually does not help much to avoid using electricity later unless you have some form of storage (e.g batteries, thermal storage tanks)

That's happening is you have inflexible electricity sources - your so-called "base load generators" - that cannot be throttled down, and renewable power that is very "use it or lose it" since they cannot be dispatched on demand, resulting in a surplus of generation. Wholesale electricity prices go down because supply exceeds demand, and continues into negative wholesale prices because you cannot tolerate a surplus of generation without destabilizing the grid.

So yes it's about "using power when it's there" but it has nothing to do with "not using it when an expensive plant would have to be turned on." It has to do with the fact that you can't turn some plants off and they need to encourage extra usage during times of glut to avoid crashing the whole system. Operators have no problem with people using "expensive" electricity 'cause they're gonna pass those costs on to you anyway.
