This past summer, I gave a lecture at a web conference and afterward got into a fascinating conversation with a young digital design student. It was fun to compare where we were in our careers. I had fifteen years of experience designing for web clients, she had one year, and yet some how, we were in the same situation: we enjoyed the work, but were utterly confused and overwhelmed by the rapidly increasing complexity of it all. What the hell happened? (That’s a rhetorical question, of course.)
The power consumption of our high-tech machines and devices is hugely underestimated.
When we talk about energy consumption, all attention goes to the electricity use of a device or a machine while in operation. A 30 watt laptop is considered more energy efficient than a 300 watt refrigerator. This may sound logical, but this kind of comparisons does not make much sense if you don't also consider the energy that was required to manufacture the devices you compare. This is especially true for high-tech products, which are produced by means of extremely material- and energy-intensive manufacturing processes. How much energy do our high-tech gadgets really consume?
