Renewables are great, but they cannot sustain current power needs alone. Both solar and wind also have the problem that they cannot generate power 24/7. So at times where they are able they generate a lot of excess power that cannot be stored at that scale and at times where they cannot generate power there are shortages.
Even if they could operate 24/7 it would still not be enough power to satisfy current demand. Then there's the waste they create once parts need to be replaced, which is much more frequent than non renewables.
It's all very messy and there is no silver bullet.
