Geosynchronous orbits do not pass through the Earth's shadow as much as you might think. These orbits sit in the same plane as the equator, which is tilted 23.5 degrees when compared to a line from the sun to the earth. They still pass

It is not just one grid operator (though some may be worse than others). Electricity demand in the US has been flat for the last 20 years[1] because all growth has been offset by efficiency gains. The same is true in Europe, e.g. Germany[2]

Presumably the negatively priced energy came from solar panels, so those sun rays were going to heat the planet anyway. The same still happens with a dummy load, just with extra steps in between to convert to and from electricity. With enou
