Am I everything you need? You better rock your body politic now!
I had an epiphany about sustainability and engineering a few years ago. This is during me learning about climate change, all its facets, what to do about it, etc. It's a bit lengthy, bear with me.
If you look at the quintessential "engineering thing", it's a car. It's described as a system, where you take a bunch of parts (not very useful), put them together, and now they do something useful. The way to express this is that it's "greater than the sum of its parts".
This works, but the explanation opens another question: OK but the car is part of another system, and in order for it to work it needs a constant input from that system (petrol). That input requires a bunch of other complexity and causes a bunch of problems. So the "car" as a system is actually the entire extraction chain to feed the car to do the work. Not exactly "greater than the sum of its parts".
A bike, however, that does the business! A bunch of parts, put them together, boom! Greater than the sum of its parts. Yes, you need an extraction system to make the original bike, but the parts are there for their lifetime. You can recycle them after. Those aren't part of the "system" which you can look at as the "bike". Bike is a pure win. It's Engineering (tm).
Now let's look at other things which engineers build which you can look at and see as "greater than the sum of their parts". You can see refrigeration, nice, (electric) cooktops / kettles / toasters and other renewable powered electric infrastructure, nice.
Basically, everything that makes your house run is pretty great, and if you just wave your hands a little bit, say you have solar on your roof, that's powering the devices, great! System!
What about software? Well, it's a bit harder, but overall the idea is that you need to communicate to solve problems, and instead of the artifacts being in the physical domain, you can compress them in software and that solves a problem. It's also electrically powered, no problem. Silicon itself can't be recycled, but the components can, and Silicon is "sustainable", there's a lot of it. System!
OK hold that idea. 1/n
