for those of us not in the bay area, it's good to think now about what to do if the power grid goes out for hours, days, or even weeks. these kinds of systemic cascading failures will be increasingly common as climate change begins to get into gear this decade.

the infrastructure almost everywhere wasn't designed for rapid changes in climate and increasingly severe storms. much of it is already pushed past the end of its expected lifespan. if you can, gather materials to ride out power, water, and supply chain disruptions and get more than you'll need so you can share

@substack I think we'll see increasingly products quietly designed for this.

A lot of it will be in home battery storage, which is already taking off and is needed to deal with the duck curve problem too.

There are a couple of grid tie inverters that can kinda, sorta power one outlet when the grid is down and the sun it shining.

The Enphase IQ8 microinverter promises to take that a lot further.

@joeyh climate chaos affects the supply chains for these products too. present levels of consumption (and thereby extraction) simply aren't sustainable and that goes for off-grid "renewable" tech as well. using much less energy by being selective and careful about the technologies you do end up using solves a bunch of problems at once

@joeyh for example, at our farm we are entirely off-grid and most of our systems run direct on 12v or 5v. 2 of the small solar systems are 12v directly and 1 is 24v but has a buck converter to step the 24v down to 12 and we use automotive ports and usb everywhere. we barely use anything AC, only really the soldering iron and hot glue gun, and those are from a 300w inverter designed for car power ports


@substack yeah, I followed spider-farm when you were on scuttlebutt. I'm 100% offgrid too, and my house uses around 1/10th the US average energy.

But there's alternative and then there's mass market, like it or not, so I am excited when I see indications the mass market is making any kind of improvement.

@joeyh @substack Best cheap option: buy a cheap used top-loading freezer from a liquidator or junkyard. Add a thermostat that keeps it at refrigerator temperature. Works on very little energy, easy to run from solar.
