@bradr@infosec.exchange Here is a year in South Australia. Green for solar+wind, black for gas and diesel, purple for battery charge/discharge*. Such is the height of the daytime solar generation across Australia, mostly from residential solar, that there will be three hours of free electricity from June. The South Australia state Premier says all electricity in the state will be zero carbon by 2027. Edit: a caution about interpreting these figures. This is electricity usage as *seen by the grid*. There is a huge amount of daytime power consumption which is powered from on-site solar panels, and so not seen by the grid at all. No one knows how big this 'behind the meter' usage is, but based on panels sold it is expected to be huge, as part of the rationale for a household installing solar is to run the summer air-conditioning for 'free'. There are pleasant spring days (no heating or aircon) where the entirety of the state is powered from residential solar alone. * Battery charging is solar+wind in SA, so count that as non-fossil.
