Look at the trend lines. Solar and batteries are getting cheaper on an exponential curve; nuclear and fossil fuels aren't. Those trends won't continue forever, but they're pretty much locked in for the next few years because the engineering work is already done and often contracts are already in place.
Short-term we're waiting for mass production and distribution of the new designs (relatively easy to predict), not R&D which is less predictable.
