This was always my understanding of how renewables make the concept of "base load" irrelevant, again, as a person with a literal degree in Electrical Engineering.
But I was gaslit by so many people that I felt the need to research the current situation again today.
This could just be people using out of date information, but I suspect this is anti-renewables propaganda. Otherwise I don't know why so many people would even know what a "base load" is.
