+1 w/Renegade. I'm actually doing as much as possible to reduce my technical and energy footprint these days. My new goal: As little as possible - and simplify, simplify, simplify.

I do a lot of work in the smart device industry, which is just one part of the Internet of Things (IoT). I've also done work on IoT infrastructure, and had a few policy papers come across my desk.
In order to get those resource savings (electricity, gas, water), you're literally telling your utility company (and anyone that wants to hack the insecure systems that are used/will be used) what time you went to the bathroom and whether you took a pee or poo.
