FWIW, there's already a $10/mo minimum monthly charge, and a $0.02-$0.03/kWh non-bypassable charge for all energy consumed from the grid in NEM 2.0. So even a net-zero solar customer always pays $10-15/mo or so. The onl

Well, if my net usage from the grid were to drop to zero, without solar (say because I used a gas generator or whatnot), I’d basically be paying the utility zero too (modulo some small connection fees). The utility still wouldn’t save on a

Yep, just as they did with the 2013 Mac Pro. We all remember how well that worked out. There's a substantial subset of high-performance computing tasks that are limited by GPU performance. But that's far from the whole equation.

Err.. that’d be 1088. Saracenic education in 1988 would’ve been quite something, I’ll wager!

Yes, there’s an assumption by lots of folks that things will ‘recover’ and return to a similar state as the past, but that’s not what usually happens with megafires, especially with a warmer, drier climate.

Smoke in Idaho and western Wyoming was awful a few weeks ago. Maybe it’s improved since then, but I wouldn’t bet on it. Maybe central Montana?

It’s pretty bad news for the creatures and plants in that ecosystem. Maybe in evolutionary terms it’s not a big deal, but it will mean the wiping out many populations and even species. At a personal level, the extinction of the giant sequo

Even back in 2019, without federal incentives, people were walking out the door with new Bolts under $30k (including tax and registration). It’s more than possible - it’s already happened. The problem is that most Americans buying new veh

This nicely captures the crux of the argument. I suspect it also explains why you’re going to have an uphill battle convincing a lot of folks. When the presumption of ill intent (and not e.g. confusion or ignorance) is automatic, there’s n

Depends entirely on the vehicle. The lookback on some is fairly long, others not so much (Bolt EV). New EV users often forget that unlike 'gallons of gasoline' or 'kWh', 'estimated miles of travel' are not a t

Sure, and when they do, we can have that conversation. But claiming that what’s available today from Apple is of great interest to the high performance market is jumping the gun. There’s also the fact that cost (including peripherals and su

Many EVs automatically charge the 12V battery from the traction battery. Still not ideal, but it does work in a pinch.

Certainly true, but as the article notes, it means that you're going to need to account for a good cooling setup when you build one of these systems. Last few systems I've built (Haswell i7 and Skylake i7) have used relatively in

This feels a bit like they just took an existing Intel design and tried to adapt it for AMD. Nothing wrong with that per se - by all accounts it's a good solid board - but it leads to weird choices like not using 56 of 64 PCIe lanes o
