After someone here linked a number of these, I've become something of a junkie following sites like this which show power generation around clock.
My armchair assessment in terms of utility carbon footprints these past few months has been that places with substantial hydro and/or nuclear capacity have fared best, though this past season has been rough on the former at least here in North America with drought-like conditions prevailing. Wind has also been disappointing. No wind during these heat dome events. Solar has done better, but even in a state like California that is fairly heavily invested in battery backup, the dream of a 24-hour solar grid still seems aspirational at this point?
