It is going to take a long time and a lot of resources no matter what so maybe we should be building effective longterm solutions like nuclear instead of stopgap solar and batteries
Why would, e.g., solar and chemical or physical storage be a stopgap? Why spend 20 years of building a fission reactor these days (other than for research, medical, or defense purposes) which also make awful targets in a conflict? Maybe just wait till fusion reactors are there.
Not even “instead”. We need all of the above: nuclear for base loads, solar for peak loads, batteries for surplus capture.
