Will inefficient JavaScript increase power consumption? Will videos and images? I think so. By all means plant some trees instead, but most of us don’t. We code. And when we do, if we consider efficiency a bit then we actually might move the needle, however slightly. It all helps.

I think my argument is that thinking about efficiency at this scale actually costs more and uses more power overall.

It's like spending an extra ten dollars once to save a tenth of a penny on each future tank of gas. Yes, there are times where that trade-off makes sense, but for most folks it won't actually make things better and could make them worse.

The author doesn't have any data to suggest what the savings here are. I assume these are miniscule or even immeasurable benefits that come at a very real cost in time and resources.
