19:24What is the role of distribution utilities in the energy transition? Consider this paradox: Marc England, CEO of Australian distribution utility Ausgrid, has two batteries at his home but no solar panels. Instead, he buys grid power at 5 cents per kilowatt-hour during midday solar surplus, stores it, and then sells it back to the grid when prices a…

22:42Over the past decade, China has transformed from a heavily coal-fired country to the undisputed global leader in the energy transition. The pace keeps accelerating: In April 2025 alone, China installed more solar than Australia has in its entire history. By 2030, as little as one-seventh of China’s projected spare solar manufacturing capacity could…

21:26Alaska is an energy superpower with more untapped renewable resources than most countries. Yet its largest population, in the Anchorage area, faces a real risk of blackouts beginning in 2027 due to declining gas supply from the nearby Cook Inlet gas field, which is likely to force this historical major supplier of oil and gas to import LNG to keep …

21:31Most people probably think of a “microgrid” as a campus or neighborhood that can “island” itself and run independently when needed, but otherwise stays connected to the main grid most of the time. But in Alaska’s remote communities that aren’t even accessible by road, residents depend on microgrids for their very survival in extreme conditions. For…
