Keep in mind that "renewable" includes hydro and geothermal, both of which are reasonably substantial and largely fully exploited.

There've in fact been several notable decommissionings of hydro projects, and extant geothermal (such as The Geysers in northern California) are producing well below their peak due to field exhaustion (various factors, typically groundwater and/or actual thermal flux).

Wind and solar have grown markedly, but remain a small fraction of total electrical generation. Which itself remains a fraction (roughly 1/3) of total energy consumption.

are those percentage in peak theoretical capacity or base load

I think it’s peak output
