Ponzi's are very attractive too, for a while. People get a lot out of Ponzis. "the revenue collected over time does not come near to covering the costs of meeting these long-term obligations. Development spread out over a broad area is very expensive to maintain. Over a life cycle, a city frequently receives just a dime or two of revenue for each dollar of liability... Decades into this experiment, American cities ha…

You need to quit reading strongtowns and start thinking. Every city has deferred maintenance and unmeetable promises, most of it is maintenance that it is more cost effective to defer. We don't need perfectly smooth streets, so defer minor maintenance makes sense. Most unmeetable promisees are things they never intended to meet. Suburbs have existed for over 100 years. If there was a problem we would see it all over,…

"We've been throwing carbon dioxide into the atmosphere for hundreds of years. If this was a problem we'd be seeing the consequences of it by now."

Anyone who's looking does see the problem. Meanwhile there's a critical mass of people whose lives and identity revolve around the status quo and who simply prefer not to see it. The people who see the problem have been trying to tell you (and everyone else) about it, and it continues to fall on deaf ears.

I think your comment is a bit misleading. Dumping sewage into a creek is an externality that is bad. Someone preferring to live in a suburb does not mean they're generating externalities at that level. The very reason I pushed back on the comment was because of this black and white thinking. Saying > The fact that people dump their sewage into the creek instead of paying for proper sewage treatment/disposal suggests…

Suburban development, as it stands in America today, has enormous levels of externalities. The roads and sewers of suburban developments are subsidized by downtown areas which are more tax-dense. Suburban development requires cars which are always the least efficient way to get around vs. walking/transit, regardless of electrification. Suburban homes are large and freestanding both of which detract from building ener…

This is false. The tax districts are independent in the suburbs in many locations. Sewers and water are local city taxes are paid for out of the suburb property taxes. The only “city tax” subsidizing suburbs would be state taxes and that’s if and only if more people lived downtown than in the suburbs, which is not true in California.

When you've confused "per kWh cost" with "energy to the house delivery costs," this sort of stuff sounds good on paper, but it doesn't fundamentally solve the problem that in the winter, homes use a lot more energy than they can generate, and in the spring/fall, they will generate a lot more energy than they need. I've got a large ground mount solar install I put in a few years ago (15.9kW nameplate, though mostly ea…

> It's not a big deal with only a few people on the grid, but if every house were doing this, "Renewable is great, but if we're already generating all our power by renewables then..." This argument is silly because we are nowhere close to having this problem yet. And as we start to approach that golden age (I mean, "problem") we'll have other alternatives.

Iowa is actually close to having the problem of more renewable power than demand. We are a small state yet ranked number two in wind production: your state should aim to overtake us.

$5000 tax credit for a ZERH home that may cost $400k to build. Just from an incentive pov is it enough to swing the needle? Most probably I am glossing over something.

For someone already wanting to build a house, maybe. You're probably already going to insulate because it pays for itself. The tax credit makes it possible to go the extra mile.

People keep talking about the "subsidies" as if they apply to all suburbs. It seems to be an article of faith. It really needs some evidence (preferably from an unbiased source).

There are probably exceptions, of course, but surely the basics are not controversial, e.g. that public infrastructure spending per capita tends to be much higher in suburbs than in urban areas, carbon emissions per capita are much higher in suburbs, etc. Not to mention that political representation in the United States favors lower density areas.

A few industrial users can weather changes in supply, with notice of the expected price in advance. The aluminium smelter can heat to x+250°, let things cool to x° while people cook their evening meal, then heat up again afterwards. A large supermarket chain can set their refrigerators to 5°, but by allowing the range to move between 3° and 7° can save significant power. (One of the big British supermarkets already d…

That only works on short timescales, which isn't the main problem because there are so many ways of solving that (for example batteries or thermal storage for home heating).

If they have notice the smelter will be happy to shutdown for maintenance for a few months. You need to plan this with them a year in advance though.

> Someone preferring to live in a suburb does not mean they're generating externalities at that level. They are, but those externalities are simply not as straightforwardly obvious.

Do you have any references for this statement.

I'm not arguing there are no externalities (there are externalities in just about every choice we make). I just haven't been convinced that there are common egregious externalities at the level of dumping raw sewage into the creek.

Almost half of Americans live in an earthquake zone. Wood is a hell of a lot safer than masonry or rammed earth in such conditions.

> Almost half of Americans live in an earthquake zone Apart from CA and maybe some other parts further North where is that earthquake zone? Seriously asking.

This is a pet issue of mine, having lived in two off grid homes going back to the 80's. The barriers are not materials, technology, or labor, but purely regulatory. I could take my current home off permanently grid with solar today for less than 10k but to do so would be illegal. Permitted grid connected solar costs 5x that and disconnecting from the grid is not permitted.

I'm just curious: what happens if a home owner installs a bunch of solar panels and batteries, declares the property "off grid" (for electricity), then simply stops paying the local utility. I'm sure the local utility will stop service, which is what the home owner wants by going "off grid". But does it go beyond that? Will the local utility put a lien on the house? Will the local utility send any unpaid "fees" to co…

The duty can remove your right to live in the house. Utilities serve the whole city, if you don't connect you are violating the unwritten agreement to help the city exist. Even if you don't use power you need to pay your share of the power lines.

What makes you think that project is relying on passive solar? In green building that concept has been largely superseded by newer standards like Passive House and Net Zero which generally rely more on air sealing and super-insulation with highly insulated windows.

There is going to be a lot of health fallout though as people start having oxygen depletion from tightly-sealed houses. It's important that even well sealed homes have both A/C fresh air sources as well as ERV/HRV systems that can recapture the heat/cold the house has while replacing the CO2 with outside air.

ERVs and HRVs are generally part of these designs. Also, nothing stops people from cracking open their windows. The windows are meant to insulate well when closed.
