Nine US states are teaming up to accelerate the adoption of heat pumps

it isn't just california either, deficient and neglected infrastructure is basically a national-scale problem.

around my area we blew up two substations during a heatwave last summer. we constantly get brownouts at 4-6pm during the post-work peak load such that I'm almost not even comfortable running the freezer/etc anymore (brownouts are really hard on motors). and now you want to push all the gas heating (and this area gets cold!) onto the grid too?

a lot of this is that urban and suburban areas are subsidizing rural and ex-rural areas - more than half of my bill is already capacity-charges and delivery fees and not the actual cost of the electric, and we're still blowing up substations regularly due to strained and overloaded infrastructure. Where is the money going? Mostly to keeping miles and miles of power lines out to the middle of nowhere, I'd think.

That's a problem America is going to face in a lot of "ghost town" scenarios - when "the mine dries up" or "the train doesn't stop here anymore" and a place stops existing, the infrastructure costs to service the 20 people still living there don't. Repaving the roads every couple of years, plowing and salting them during the winter, etc aren't free and the reality is that in some areas there's really almost no economic activity anymore to justify the cost. We just have covenants and mandates that prevent ever undoing it. And that runs up the bills for everyone else.

We have 400k people in this county of 700mi^2, and that's suburban, not-particularly-dense either. Another county we have 40k people in 2700 mi^2. Should everyone in the former have to subsidize the lifestyle of the latter? We are talking about 2 orders of magnitude less density here, while it's not quite 1:1 there's no doubt they are incurring significantly higher infrastructure costs for their lifestyle and we are paying for it.

And since people won't pay for it, what we end up with is everyone's infrastructure falling into neglect, to pay for a handful of rural customers.

> It's now more expensive to fuel a vehicle with electricity than gas

This is very hard to believe, what are you paying for electricity? California gas prices are also way above the national average at the moment. Here's a per-state comparison from last year, I'm sure it's a bit out of date but I doubt things have completed flipped in a single year: https://energyinnovation.org/2023/07/27/ev-fill-up-savings/

Napkin math:

My crossover EV gets 2.5-3.5 mi/kWh. Call it 3. / $0.2/kWh = 15 mi/$

Avg fuel economy in US ~ 25mpg. At $3.50/gal that's 7 mi/$

So at 20c/kWh, your dollar goes roughly twice as far on electric. California has been seeing brutal rates, though -- 40c/kWh not uncommon.

Californians can play games with Time-of-Use rates (charge at night), get onto EV-specific rates, be on a CCA which tend to not have the try-to-not-burn-down-the-state adjustment fees, get solar +/- NEM2 vs NEM3, etc., so your numbers may vary. And different cars will have different MPG's of course. But all of that is to say, "more expensive to fuel a vehicle with electricity than gas" is not necessarily wrong in California.

Heat pumps are much more common in warm areas than cold ones, because the difference between an A/C and a heat pump is really just the ability to reverse the refrigerant flow, and they're very efficient at heating in mildly cold weather. I grew up in Florida, and pretty much every house there had a heat pump even thirty years ago, with electric resistive heating that kicks in when ambient temperatures drop below 40F or so. Where heat pumps don't work so well is when ambient temperatures are very cold, which is why adoption in northern states has been much slower.

EDIT: My grandparents' house had a thermostat that looked like this: https://i.ebayimg.com/images/g/uqsAAOSwTVlbyNN9/s-l1200.jpg They would call very cold (for Florida) weather "blue light weather", because the blue "aux heat" light would turn on on their thermostat, indicating that the system had switched from the heat pump to the resistive heat strips.

One issue with heat pumps is they are more complex in terms of modes they can be in, especially if you have multiple zones. I was troubleshooting an auxiliary heat issue and had to pull from the Ecobee API just to make sense of what was happening on cold nights across zones.
