Use clean energy charging on your iPhone

So they shouldn’t do this?

I’m so tired of this kind of marketing. Meanwhile, if your SSD dies on m1 macbook, the laptop becomes unrepairable. If Apple would care about ecology, they would at least allow to resolder it.

Let's assume an average iPhone battery is 5.45Wh and that they are charged to full every other night. That is 0.99kWh/year. We know there are 136 million iPhone users in the USA (1) so we are looking at 134GWh of electric consumption shifted to green generation.

Now assuming those phones were previously charged on the standard energy mix in the USA that is 0.368kg of co2 saved per device per year, or 501,584,76kg of co2 saved. That seems like a huge number! But is it?

Well let's put it in perspective. A flight from Heathrow to New York emits 312kg of co2 per passenger (3) so we have saved the equivalent of 600 fully loaded transatlantic flights. There are ~1700 flights a day so it doesn't seem like a huge difference. Disappointing.

But it seems like a pretty easy win so at this point I ask why not do it? I'm a big believer in aggregation of marginal gains and there are 10x that number of iPhones worldwide and many more Androids.

> I'd love to be able to put a wet load of laundry into my drier and press "make sure it's dry by tomorrow morning".

So, I do a bit of this myself, manually. I've got a table of appliances and wattages, both rated and measured (using a Kill-O-Watt). I also have a 6kW (max) solar panel installation, plus I'm on a time-of-day metered plan.

I try to make sure that anything that uses hot water (tankless full electric water heater; 29kW rated max) like the dishwasher and shower are done between 1000 and 1400, as that's the highest time of solar insolation during the day, plus the time of day turns over to the highest tier at 1400.

I've bought but not yet installed an eMonPi (https://github.com/openenergymonitor/emonpi), so theoretically I could automate some things to optimize when to run devices. As it is though, by tracking and actively trying to reduce consumption, I've already managed to keep my electricity bill to zero for years, even putting thousands of USD back into the grid (sadly, I do not get money back from this; it only counts as credit, and resets every twelve months).

As for your specific example, I line dry my laundry. I don't see the point of running a space heater (dryer) in my garage; it usually only takes a few hours to dry where I live anyway. The only reason I still have a dryer is for down sleeping bags and coats that have to be fluffed up.

My guess is that one’s iPhone will one day become the « brains » for a home’s appliances and control all that.

You’ll set your alarm for 6am and then the dryer will know to dry by then.
