Data centers have become the largest driver of surging electricity demand that is straining US power grids. But the AI data center boom has also accelerated investment in a technology that could provide a silver lining for everyone—solid-state power transformers that replace industrial-age technology with modern power electronics.

Power grids currently rely on conventional transformer technology that is painstakingly assembled by hand and has a fundamental design dating back to the 1880s. Two copper wire coils manually wound around a steel core create electromagnetic fields that help step up voltage levels of alternating current electricity for long-distance transmission or step down voltage levels for the electricity use of homes and businesses. The largest power transformers cannot be mass-manufactured but are instead custom-built for each utility company’s electrical substations.

Manufacturing constraints, coupled with the scramble to upgrade US power infrastructure, have meant utility companies and other customers must wait up to several years for delivery of new power transformers. That is not only a problem for expanding power grid infrastructure to support growing electricity demand, but also delays the process of replacing aging power transformers.

Ads and tracking have turned TVs into privacy nightmares. Both are so widespread among smart TVs that I’ve written a guide for avoiding them. One recommendation in that guide is to use a computer monitor. But in recent years, monitors have become more capable of pushing ads and tracking users.

Without more straightforward approaches from vendors, such as easily comprehensible privacy policies and avoiding inappropriate ads, monitors are dangerously encroaching into smart-TV-like territory.

LG monitors’ McAfee ads

LG lost some trust after a recent report that some of its monitors installed McAfee pop-up ads onto connected computers. Since at least 2024, some of these displays installed an app, LG Monitor App Installer, onto connected computers under the cover of driver updates installed through Windows Update.
