> Nuclear is obsolete to what? As far as I understand, nuclear is the replacement for coal, nothing else comes close to being able to provide a stable constant supply in large quantities. The article pretty clearly demonstrates that grid-scale battery storage systems are able to provide very fast reaction times. More battery storage systems, along with other forms of energy storage such as Solar-Thermal and pumped-hydro can take daytime generation and make it usable at night. They're proven workable grid-scale technologies. Large widely distributed deployments of Wind generation can also provide a lot of capacity. For those who claim wind doesn't always blow - well, it's always blowing somewhere. Having a lot more individually smaller generators plus energy storage will inherently permit a more stable grid - one smaller generator tripping offline doesn't cause a massive issue.
