Russia’s effort to conscript 300,000 reservists to counter Ukraine’s military advances in Kharkiv has drawn a lot of attention from military and political analysts. But there’s also a potential energy angle. Energy conflicts between Russia and Europe are escalating and likely could worsen as winter approaches. One might assume that energy workers, who provide fuel and export revenue that Russia desperately needs, are too valuable to the war effort to be conscripted. So far, banking and information technology workers have received an official nod to stay in their jobs. The situation for oil and gas workers is murkier, including swirling bits of Russian media disinformation about whether the sector will or won’t be targeted for mobilization. Either way, I expect Russia’s oil and gas operations to be destabilized by the next phase of the war. The explosions in September 2022 that damaged the Nord Stream 1 and 2 gas pipelines from Russia to Europe, an...

In areas where storms or extreme heat and cold have knocked out the power for days at a time, people are starting to ask whether investing in rooftop solar and battery storage systems can keep the lights on and the air conditioner running when the power grid can’t. When the grid goes down, most solar systems that lack a battery will also shut down. But with batteries, a home can disconnect from the grid. Each day, the sun powers the home and charges up the batteries, which provide power through the night. Our team at Berkeley Lab explored what it would take for homes and commercial buildings to ride out long power outages, of three days or more, with solar and batteries. How much can solar + storage do? For a 2022 report, we modeled a generic power outage for every county in the U.S., testing whether a rooftop solar system combined with a 10- or 30-kilowatt-hour battery could power critical loads, like refrigeration, lighting, internet service and well pumps; if it could...
