Oh yea I definitely think EVs are the future and to the extent that we have vehicles, in the majority of cases they should be EV. I guess what I'd say here is that even at a reduced cost (which is arguable) for a "commute" (self-driving, etc.) you aren't going to get EVs cheap enough to offset b/c the very act of driving 10, 20, 40, miles to a job or driving a mile down the road to the grocery store is just incomparable to just better design. If your grocery store is within a half mile and you can walk or bike there, EVs could never compete. So it's kind of like we're improving the technology of something we shouldn't be doing, versus just not doing that thing.

If I had to completely armchair it here, if you looked at total impact to society, the environment, car accidents, you name it something like a gallon of gas in the US should really be about $20-$30/gallon but it feels like it's expensive at $5 b/c we're so used to the low prices. We are probably experiencing these costs through inflation and things like housing prices.

Renewables (should) drop overall energy costs by virtue of capturing natural movements (I'd throw nuclear in renewable as well IMO but I understand why you wouldn't) but people are going to focus on kWh being expensive because they're used to extremely cheap gasoline. I guess in other words renewables on paper will be more expensive "at the pump" but externality cost to society will be lower. I wouldn't be surprised if in the future as more EVs come online that energy costs to charge even at home are approximate to gasoline.

Price per gallon is probably the wrong unit. You probably want $/mile. Car accidents get priced in via insurance. Environment isn't priced in at all in the US, though a carbon tax could change that if there was any political appetite for it. EVs already significantly reduce fuel and maintenance costs even though ICE cars enjoy a "carbon subsidy" (i.e., pollution isn't priced into the cost of gas).

> people are going to focus on kWh being expensive because they're used to extremely cheap gasoline

Electricity is already much less expensive than gasoline. The current US-average gas price is $4.10/gallon and a 30mpg car will cost over $0.13/mile. The current US-average electricity price is $0.14/kwh--with ballpark 85% charge efficiency (not all energy drawn from the grid makes it into the battery) and 300wh/mile, an EV will cost less than $0.05/mile. EV fuel costs are just over a third of those of ICE vehicles.

How I'd phrase that is: "Electricity is currently much less expensive than gasoline "at the pump". What I think is likely to occur is that as we switch over to EVs (I own one btw if that helps here) there will be continued pure electricity demand which is going to cause prices to go up and up. Everything runs on electricity, and soon cars will too. So I think the kWh price is going to go up, and be measured and scrutinized much more (you can make an app to calculate this, not so much with gasoline easily) and it'll be more measurable. But gasoline costs just aren't "counted" in the same way. So eventually it'll cost, idk, $20 to go 300 miles and people will think that it's expensive because you could do it with gas much cheaper in the past, but the problem with that comparison is you wouldn't have accounted for the externalities so you're not really getting true costs. I hope that makes sense where I was going with that.

I agree $/mile is the right unit, I was just thinking about how to isolate true gas cost versus true kWh rate in some way. I personally pay closer to the $.05 kWh rate at home, but I see peak rates in California hitting $.4/kWh and all I see is the writing on the wall for the rest of the country.

If I had to summarize:

We live in an era of extremely cheap energy. It may go on for another 50-100 years, who knows. Maybe it goes on forever. But it won't be from fossil fuels. And if energy becomes much more expensive and we haven't designed cities and transit for optimizing cheap/efficient energy costs we're beyond screwed. Relating it back to housing, I think it makes sense the housing is getting much more expensive and that this phenomenon is more than just "living somewhere cool" and part of the reason that people want to live in these "cool" places is exactly because the implicit energy costs are less. You don't have to drive to a coffee shop. You walk.

I guess one good thing about America is we have all of these navigable waterways so we won't have big food shortages as distribution costs can remain reasonable, at least in the mid west and the east.

-edit-

One startup idea I have is a way to truly measure your total energy expenditure. Right now I just get a bill in the mail and figure that it makes sense because it's sooooo cheap to run all of this stuff. What happens once energy becomes 5x more expensive? Well, I want to know how much it really costs me to run dual monitors. Maybe it's an extra $50/year I don't want to spend (just a contrived example).

Agreed that increased electrification of previously fossil fueled applications will create upward pressure on prices, as will the decomissioning of fossil fuel power plants. However, this will eventually stabilize as we (1) increase renewable capacity and (2) increase our efficiency (American energy consumption is decreasing gradually as we improve efficiency).
