It might be easier for DC transmission components to be standardized. Sure, anything with complex controls has a lot more opportunity to fail to interoperate, but DC gear can often be configured for different voltage ratios and can much more directly control how much current flows where.

Maybe the grid needs a multi-source agreement for equipment like the network industry has for optics.

Yet another good reason for at-home solar and storage.

Does very little to offset things like no power for hospitals, refrigerated food distribution, manufacturing of almost anything.

Also the sewer system backs up after about a week because the pumping and lift stations need power to operate.

The water system shuts down because the tanks aren't reserve supply they're pressure support.

And solar plus storage will keep you running for maybe a week if you're conservative and mostly don't use anything...which doesn't help you if it's months till replacement.

solar + storage + water sheath fireplace can run pretty much till you run out of wood.

But yes, unless you spend serious money (own sewer, water from underground etc), it's basically solution for "the power pole is down", not any grid wide problems.

It is often the case (at least where I live) that having a septic system and well is far more economical than obtaining a property with access to city utilities.

I mean "run out of wood" is the problem though. There aren't that many trees, certainly not enough for everyone in a region to start doing it.

You'd be better off with an air sourced hear pump for hot water anyway - the one in my house uses less power then my dehumidifier.

> no power for hospitals

Which have days worth of backup generator power

> refrigerated food distribution

Do you think refrigerated trucks trail big long extension leads to a socket somewhere?

Way stations still need power to accept and refrigerate shipments. Distribution isn't just on trucks - although they could act as a small stopgap that also prevents them from making deliveries while being used as storage.
