Sun and wind aren't the only renewable energy sources. There is also geothermal and hydroelectric power for example. Countries like Iceland and Norway already do or are close to meeting all their energy needs with 100% renewable energy sources. Studies like [1] seem to suggest that the problem of grid stability can be solved through decentralizing and interconnecting power grids and energy storage. I'm not saying such a transition isn't a challenge, but I have yet to find a source claiming a stable grid would be impossible without nuclear energy of fossil fuels.
