#OptGreen with #GNU/#Linux to keep your device in use! These machines will run beautifully for many years to come.
Not only wallet friendly, #upcycling keeps CO2 emissions out of the atmosphere. Ca. 75% of Apple's emissions comes from production alone (details in alt text).
I may be completely wrong but don’t Samsung, Google etc. stop supporting OS updates on Android phones after 5-6 years?
Apple have supported devices for 6-8 years AFAIK.
That would be nice for iPhone, I’ve got a perfectly fine iPX that I’m only going to upgrade because my banking apps are going to drop support for iOS 16 soon
It is said that ACs are counterproductive in fight against global warming, in that while they may make the local environment temporarily livable, the greenhouse gases produced while making the electricity needed to operate them heat up the rest of the Earth by much more than the relief from the AC itself. By how much exactly is...
The answer is 1:1, conservation of energy means that 1kWh of energy going into the AC you introduce near as makes no difference 1kWh of heat energy into the world. The wonderful thing AC does is amplify that cooling or heating by moving heat from one place to another meaning modern systems can move 5kW of heat using only 1kW of energy. In this example 6kW is outside but you have removed 5kW from inside so it’s still just 1kW net.
If you want to reduce the impact of using your AC you need firstly insulate the crap out of your house to prevent heat escaping or entering. Then you can delve into the world of Mechanical Ventilation Heat Recovery (MVHR), sealing all the air gaps in your home, at least quad-glazing, and finally passive cooling (sun shades over your windows).
Edit: sorry forgot to say for solar powered AC - which is 100% of my systems. I’m ignoring the grid for the above as the only systems I install are combined with at least 3x kW of solar and batteries so they never use grid power.
In terms of kWh per kWh, by how much does greenhouse CO2 from running an air-conditioner heat up the rest of the Earth?
