Dryers in the US consume ~3% of residential energy budget, 6x washing machines
(news.umich.edu)
Researchers from the University of Michigan are hoping their new study will inspire some Americans to rethink their relationship with laundry. Because, no matter how you spin it, clothes dryers use a lot of comparatively costly energy when air works for free.

Linear Pluggable Optics Save Energy in Data Centers
(semiengineering.com)
Linear pluggable optics (LPO) is garnering more attention as a way to quickly and efficiently move data in and out of server racks, but a lack of standards for connecting the optical modules is slowing adoption at a time when there is growing pressure to reduce power in data centers.

Closing the “green gap”: energy savings from the math of the landscape function

I recently returned from the 2025 Annual Meeting of the “Localization of Waves” collaboration (supported by the Simons Foundation, with additional related support from the NSF), where I learned (from Svitlana Mayboroda, the director of the collaboration as well as one of the principal investigators) of a remarkable statistic: net electricity consumption by residential customers in the US has actually experienced a slight decrease in recent years:
