One aspect I didn't see much discussion on is about tradeoffs. Yes, computing demand is increasing, but does it all have a negative environmental balance?

Example - modern cars. They are full of electronics (there are around 80 ECUs in a modern car), but these electronics make the cars safer and lower the fuel consumption. Just look at how much the CO2 output for the same engine power decreased over time. Some of it comes from better mechanics like turbos or filters, but a lot of it comes from better electronics in the engine ECU.

Another example - logistics. Delivery companies are able to much better plan demand, routes and inventory thanks to big data processing in data centers. Yes, a data center consumes a lot of energy, but it also helps reduce emissions from trucks driving around less.

I don't have exact numbers, but I think everybody can imagine how increased computing in some areas (not all) improves the environmental impact. These are things that need to be considered in order to avoid unintended consequences.
