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…

27:19This episode cuts through the noise around energy transition progress with hard data from one of the year’s most important reports. Despite claims from both “fossil gradualists” who would like to see the energy transition fail, and “net-zero puritans” who deny that the energy transition is happening at all because emissions are still rising, the tr…

Various biofuels such as ethanol, biodiesel, sustainable aviation fuels (SAF), and wood for power plants are labeled as renewable and carbon-neutral. But are they really? If a farmer converts food-producing land to grow corn for ethanol, does that acre actually reduce carbon emissions? When trees are cut down to fire power plants, can we have confi…
