Biden Administration Is Said to Slow Early Stage of Shift to Electric Cars::The change to planned rules was an election-year concession to labor unions and auto executives, according to people familiar with the plan.
They are too expensive. But only because auto manufacturers are only making midsized and larger suvs or luxury cars. The average price of an EV has dropped over 50% in China since 2015. That would have been tough for us to match, mostly because of batteries, but we could have made much more progress than we have.
The electric grid isn’t nearly as unprepared as people say. Sure, we need to build out more charging stations, but the grid as a whole far exceeds current needs. In fact, nationwide electrical usage is actually trending down in the US because of efficiency gains. Better building codes, heat pumps, LED lighting, if it uses electricity newer stuff is more efficient. If we had sold 8 times as many EVs in 2023 than we did, electricity usage would have stayed about flat.

Here’s the story as I understand it. US automakers want to make expensive premium cars because those sell for high margins. The big breakthrough in the EV market over the past few years has been China EV makers figuring out how to make cheap and “good-enough” EVs, which are catching on in many places across the world. This is clearly the direction in which the market has to move (whether via Chinese or non-Chinese automakers) to spur mass EV adoption. In the US, however, the established automakers can rely on protectionism to block imports, this keeping the US market limited to big expensive cars that remain using ICEs.

They just announced that’s the plan actually

it sounds like maybe they should, idk? work on making their own garbage cheaper then? that soley sounds like a competition problem not a consumer problem. As long as the cars meet US safety standards for manufactoror I embrace the competition
Billionaires love laissez-faire capitalism until it comes to bite them in the ass
The geopolitical calculus here is about manufacturing.
If China owns EV production lines, that gives them the drone advantage in the next war, as the Li-ion battery is the hard thing to make in a drone.
If USA has EV lines, even if it’s more expensive, we have the resources to make drones as well. (Or Li-ion batteries in other useful weapons).
Ceeding the military advantage to the Chinese for some cheap consumer goods is a bad tradeoff, especially as China is building a Navy to fight us in Taiwan.

Japan did it. Korea did it. China is doing it.
You sound informed, more so than I. The heat pump thing confuses me, and I’ve seen it a lot lately.
I was under the impression that the vast majority of homes were using a heat pump system. Seems like a no-brainer? Is this not so?
EDIT: My HVAC is labelled a “heat pump” and no one around here had natural gas.

A increasing percentage of new construction gets heat pumps. Some replacement HVAC units make the switch, but there is still a large portion of people who won’t because of misinformation and/or stubbornness.
But, unfortunately, most existing residential systems do not use heat pumps, under 20% in the US I believe.
No.
Typical gas / coal plants are ~40% efficient. That means that if you do natural gas -> electricity -> heat pump, you only have 40% of the energy available to you. Yes, Heat-pumps then multiply that 40% energy out into “energy movement” rather than heating, but its a huge efficiency break.
If you instead run a pipe from the central source of natural gas and then burn the natural gas inside of a home, you have something like 95% efficiency (5% lost in the chimney).
Its only in the most recent decades have heat pumps actually become more efficient than burning natural gas inside of homes, because you have to factor the inefficiency of the power plant in your conversion. So today we’re finally in a position where modern, advanced, efficient heat pumps are worthwhile. But go back just 20 years ago and the math still pointed towards burning fuel inside of our homes as the most efficient solution.
Nope. Burning gas and direct electric heat of some sort are still the most prevalent forms of heating in the US, and often have separate cooling systems.
New building almost all use heat pumps because they are a no brainer, but a house built 60yr before the technology existed may still be using a very old heat source. Many people do not have the 20k+ to retrofit their current home with heat pump technology even if it can save hundreds/month on their power/gas bill,so here we are.
On the plus side, it is one of the lowest hanging fruits to reduce your bills long term, along with sealing drafts, insulation and replacing your water heater, so many people who have the means are opting to do all of the above.
As a renter, I have no way to charge an electric car nightly. The availability of charging infrastructure outside of private homes will be more and more of an issue, unless battery tech significantly improves to be at parity with gas (e.g. I spend 10 minutes at a public charger as if I were filling a gas car).
