Renewables are limited in some areas by hostile legislation and in other areas by reaching saturation for non-dispatchable energy. There's also a paradoxical cost risk created by such rapid improvements because faster deployment and plummeting prices can mean projects started after yours could finish sooner and cheaper. In spite of this, PV is selling out as fast as it can be made, wind is being built as fast as it can be permitted, and demand is so high that prices decreases have slowed in spite of manufactuing continuing to get more efficient. Batteries are a bit of a bottleneck (flow batteries are lagging a bit, but getting there), but sodium ion is here next year and lithium capacity is increasing at record pace. Policy is kinda lacking in most areas for building out the necessary non-battery storage, but off river and blue field pumped hydro is picking up, and china is advancing the state of the art on concentrating solar (which is dispatchable over ~12-36 hours) and compressed air storage. Europe is also starting to build out thermal storage (which is dirt cheap in the most literal sense because it's made out of the sand that is worthless for other purposes).
