Energy supply

After nearly two decades of stagnation, U.S. electricity demand is surging, driven by growing numbers of electric cars, data centers and air conditioners in a warming climate. But traditional power plants that generate electricity from coal, natural gas or nuclear energy are retiring faster than new ones are being built in this country. Most new supply is coming from wind and solar farms, whose output varies with the weather. That’s left power companies seeking new ways to balance supply and demand. One option they’re turning to is virtual power plants. These aren’t massive facilities generating electricity at a single site. Rather, they are aggregations of electricity producers, consumers and storers – collectively known as distributed energy resources – that grid managers can call on as needed. Some of these sources, such as batteries, may deliver stored electric power. Others may be big electricity consumers, such as factories, whose owners ha...

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...
