More renewables.
We’re at the beginnings of having useful levels of storage and can keep building out renewables while we develop storage. At the current rates of adoption, we’ll need true grid storage in about ten years.
However, note that one option for “grid” storage is a battery in every home. Another is a battery in every vehicle. Neither is the best option but those are options we already know and just need to scale up
Time doesn’t care. Neither does the rate of climate change.
