This is super cool! For California, my understanding (from PG&E materials) was that highest demand and carbon intensity was around 3pm to 9pm. The graph here seems to show that even though demand/supply is smaller at night, we have very little non-solar renewables so that carbon intensity is pretty bad all night as well... If that's true, I'm curious why PG&E makes it sound like electricity use at night is not as bad. Do they anticipate bringing more wind online and are trying to get ahead with the messaging to the public?
