The last section is worth a read.

Good time of year to donate (in the UK at least, as the tax year starts in April). Various ways to donate depending on your jurisdiction.

Electric Shift compares the carbon intensity of your next two electricity off-peak periods so you know if it's better to run appliances (or charge the car) tonight or tomorrow night (GB only).

We're on a dual-rate electricity tariff and often have flexibility about what night to charge the car, but is it better to plug in for tonight or tomorrow night? I got bored of working it out so I made an app for to do it for me.

This is a post on our experience getting a solar/storage system installed and some other measures. Again, it's not too technical so any questions please ask. For example, I haven't touched on the backup power option as the grid here is pretty reliable.

I wrote this post for a less-technical audience but if you have any geeky questions then feel free to ask here, particularly around charging. We used a standard 13A socket for a while before getting a fast charger fitted and it was adequate. I've also worked for an EV charging company so I know a fair amount about the underlying tech.

There is some interesting info on building a cheap ~$20 purifier here: https://airpollutionguide.net/

I haven't tried as cheap HEPA filters appear to be harder to get hold of in the UK. Maybe due to different heating systems.

Clearing the Air: The Beginning and the End of Air Pollution by Tim Smedley is an excellent book if you are interested in this area.

It looks like you're using a Plantower PMS5003. I have one of those hooked up to a Raspberry Pi and it works well but I also built a few of these with ESPs: https://sensor.community/en/sensors/airrohr/

They support the PMS but I used the default SDS011. They both seem reasonable for relative values but I'm not sure about the accuracy without proper calibration. They don't appear to give similar readings to my Plume Flow 2: https://plumelabs.com/en/flow/
