VideoGameVet posted:Offer better rates at the times when you don't have higher usage seems to do the trick. Like midnight to 6:00AM. What happens when every car in America is scheduled to charge from midnight to 6, rather than a handful? Does our grid still handle that without problems, over a heatwave or a cold snap where heating/AC is still running overnight? I don't know if it is a problem, but I haven't seen any numbers saying it's definitely not going to be an issue and it seems like something we should probably consider given incidents like in Texas last winter.

The Texas grid problems were because their power generation equipment wasn't winterized and a significant portion of it froze, and also because Texas intentionally isolated their power grid from the rest of the country so they wouldn't be subject to federal regulation. Power generation will need to be scaled up somewhat to handle electric cars, but the ability to schedule charging to off-peak times when power usage is at its minimum will help a LOT, especially as electric car usage slowly ramps up.

Climate change and urgent decarbonisation should be acting as an extra incentive to reduce car dependency and develop better cities. Alas… The primacy of the car is extremely difficult to challenge.

Yeah, I'm saying we need to start developing the infrastructure now because you can't just whip up a new powerplant overnight and improve transmission when you decide you need it. It's a tractable problem, but only if we start addressing it now. Given our worldwide response to COVID, though, I'm pessimistic about our ability to solve problems before they happen.

I think we should increase taxes significantly on single family homes, with low density penalties, so that the largest users of roadways pay for their tremendous use of resources and then use some of that money to build up charging and power transmission infrastructure.

Even then, there are a lot of cars on the road, and even off peak demand can be high in unusual circumstances. I'm sure you remember last February, it would have been much worse if thousands of people were trying to charge their EVs. One other issue is that electric cars simply don't last as long. A well built ICE car can last 20-30 years with regular maintenance. Most electric car batteries have a 10-15 year lifespan, and replacing them costs more than the car is worth. I've already heard of people getting burned by buying used Teslas and being hit with a five figure battery replacement a year or two later.

PT6A, I was interested in the answer to this question, so I decided to see what the impact would be if there were a nationwide mandate that all new cars sold were electric. Ignoring 2020, there are about 17 million new vehicles sold in the US each year. I can't find a good source for average battery capacity in an EV. I used this Car and Driver article that quotes usable capacities of between 60 and 100 kWh in models from Tesla and BMW, so I'm going with 75 kWh. This would probably be on the low side if you saw an EV mandate come in place, as larger vehicles necessitate larger batteries. With the 300-400 miles range of many of these EVs, we'll say you would do the equivalent of a full charge once a week. 17 million cars with 75 kWh batteries all charging once a week for a full year would require 66.3 billion kWh of energy. Total US yearly energy consumption is 4 trillion kWh. So EVs would require 1.66% more generation capacity than you would otherwise expect in a year. However, most EV charging is done at home, and residential electrical use only accounts for 22% of total energy consumption. EVs would thus represent about a 7.5% yearly increase in residential energy consumption. e: To clarify, that would be the growth year over year until full replacement with EVs, with an upper bound at roughly 900 billion kWh. Obviously, this is all just napkin math based on incomplete data and a whole lot of assumptions. Baronash fucked around with this message at 00:19 on Jan 1, 2022 |

Also the average age of cars is 12 years, and there's 287 million total cars on the road, driving an average of 3.2 trillion miles a year. Looking up some figures, the Model 3 averages about 300 wh/mi. So, if every car in the US was replaced with a model 3, we'd need an extra 1 quadrillion watt-hours of electricity, which is 25% of national energy consumption. So literally every car going electric would increase national energy usage by 25%, or double residential usage.

Nothingtoseehere posted:It's better they use electricity than burn oil. This is even true if the same oil is burnt in power plants - greater efficenies of scale. In terms of full-lifecycle carbon emissions, EVs only reduce those by about a third over ICEVs. In particular, those batteries take a lot of energy to mine, make, and transport. And it's almost certain that they'd need to be replaced over the lifetime of a car (or the entire car replaced sooner). So the manufacturing emissions for an EV are substantially worse than for an ICEV. Also the net reduction in emissions for EVs assumes a reasonable mix of non-fossil-fuel electricity. Which is to say that in the case you suppose, where the same oil were burned in power plants, any economy of scale would almost certainly be dwarfed by the greater emissions in manufacturing the EV in the first place.

It's funnier than that. So the token's contract had a little function that is called in every transaction (create coin, transfer coin, destroy coin). All it does it check if the destination is the owner's address and if it does, it errors out. But the owner can change the ownership of the token. So after a while, the owner changed the ownership to one of the biggest exchanges. Now nobody can cash out because part of the process involves a transfer to the exchange (which is now erroring), so the coins accumulate inside the exchange, at which point the guy can just drain the exchange of its coins. (or something like that, I don't quite understand ethereum infrastructure) Apparently the so-called verifiers didn't think the implications of the "programming error". Which are really loving obvious.

You'd still be fairly boned in a sustained power outage over many days or weeks. Gas generators for emergency situations will probably need to be available on a wider basis than they are today.

PT6A posted:Yes, I agree... do we have the capacity to generate and distribute all that electricity? For the hot day brownouts, the challenge is that people want to use electricity all in the afternoon peak when the day is hottest and the grid is also straining from the heat. But cars don't necessarily need to charge at that time. Even better, if your Tesla has a 400km range on a full charge but your commute only needs 80km a day, sell back half of your vehicle battery capacity during the afternoon peak and then recharge again at night. Vehicle - to - grid (V2G) is going to take a whole heap of tariff reform, and it assumes you have a connection at your house/business that can usefully do it, but it is being investigated. A challenge is that people really don't logically price convenience. You can offer time of use tariffs to encourage cooling/heating your house during the off peak and then just maintaining that temperature, but if it involves any kind of inconvenience then consumers expect a $50 saving per day, rather than the $1 - $5 per day that they'll actually save.

Nope. Renter since 2002 after the dot-com crash and subsequent forced home sale. I charge at home at 110v because the duplex I rent has a mis-wired dryer outlet that I assumed was 220v but it's not. Turns out to be ok anyway. Cost to drive from San Diego to Vegas in charging fees (EVGo, Charge Point)? $15.00 Not a Tesla. Kia. I could deal with no home charger if I had to because the charging infrastructure here is decent.

So the manufacturing emissions for an EV are substantially worse than for an ICEV. Also the net reduction in emissions for EVs assumes a reasonable mix of non-fossil-fuel electricity. Yep. We need decent mass transit. Also one trend I see around here is a huge increase in eBikes. As in Parents taking young children to school on the back of eBikes and, for the first time in decades, lots of 10-15 year olds not depending on parents shuffling them around in land yachts. The kids are happier to drive their Rad Power Bikes around and I suppose the parents are happy not to have to drive them everywhere. Me? I spend more time on my bike than the car. I don't think I would have gotten the new EV in August 2020 if it wasn't for a job in LA and the inadvisability of taking Amtrak (with my bike) as I did for a different LA gig from 2018 to 2020. I actually got COVID on my last Amtrak trip at the end of January 2020. Suffered for a week. Wife suffered a bit more.
