Question
The climate ledger for digital systems
Answer
Adds: data centres, making devices, cooling water. Saves: journeys, heating, wasted generation.
Question
Why renewables need digital systems
Answer
Variable output cannot be scheduled, so balancing supply and demand needs continuous measurement and control.
Question

Device lifetime and grid balancing. Individual behaviour is talked about most and measures least.
