More than a decade in the making, the SunZia transmission line project, which broke ground last week, will stretch about 550 miles (885 kilometers)—funneling renewable energy from central New Mexico to more populated areas in Arizona and California. Developers say it will be capable of transporting more than 3,500 megawatts of new wind power to 3 million people in the West. Final approval came in May, with U.S. Interior Secretary Deb Haaland saying the latest application was reviewed in record time as the administration has tried to fast-track more projects. Read more

Keeping our buildings running contributed roughly 26% of global energy-related greenhouse-gas emissions in 2022, according to the International Energy Agency. For the world to reach net-zero emissions by 2050, the agency says the energy that these buildings consume per square meter (around 11 square feet) needs to decline by around 35% by 2030. Generally, AI building systems learn from historical patterns and the daily habits of occupants to predict and power things on and off. For instance, software and hardware that automatically manage lights, heating and cooling can help buildings cut 20% or more of their yearly energy use. Read more

An English startup, Heata, is using busy servers to heat water for homes. “The idea of using the wasted heat of computing to do something else has been hovering in the air for some time,” explains Chris Jordan, cofounder and chief technology officer of Heata, “but only now does technology allow us to do it adequately.” The process is simple yet introduces a radical shift toward sustainable management of data centers: instead of being cooled with fans, which is expensive and energy intensive, computers are cooled by a patented thermal bridge that transports the heat from the processors toward the shell of the boiler. And rather than operating with a data center located in an energy-intensive location, the technology works as an intermediary for computing: it receives workloads and distributes them to local homes for processing.
