Another severe wildfire season is forecast for the Western U.S. due to record-breaking heat and an abysmal snowpack. Some states and utilities are trying to get ahead of that threat using AI. In Arizona, the state’s largest electric utility is installing AI-monitored cameras across its service region. The technology identifies possible smoke and notifies human analysts for quick verification. Fire management officials say the technology spots more fires than humans, and alerts authorities more quickly, allowing for faster and more efficient action to extinguish wildfires. Similar technology is being rolled out in Colorado, California and other wildfire prone states, as well as in Canada and Australia.

Cellphone tower operators across Africa are increasingly turning to solar power to reduce reliance on costly diesel fuel and expand connectivity in off-grid areas. Diesel still powers most towers — and there are roughly 500,000 telecommunications towers across the continent — but rising fuel prices, falling solar costs and new financing models are accelerating a shift to hybrid and solar systems. The Iran war has exacerbated those supply issues. The transition could cut emissions, lower operating costs and improve network reliability. However, high up-front investment, battery limitations and operational risks mean adoption is likely to remain gradual in the near term.
