Google and other big cloud shops care a lot about energy usage actually, and contrary to popular belief many server-side applications are CPU and memory-usage bound.
Energy consumption is important on mobile as well.

- sargun 10y agoOften times energy converts directly CPU, and therefore to $$$. I think I heard a quote that a 1% CPU utilization change in search was a $100M+ spending change. While the specifics are lost to me, in general, I'm not at all surprised. Latency a major contributor as well. Sometimes, you're just up against CPU, and latency can be closely tied with revenue.
