Last 7 days' energy supply in South Australia. SA is running at over 80% renewables (yellow is solar, green is wind)
I should've written "electricity supply" because SA still imports liquid fuels, gas, fertiliser, manufactured goods, etc
@wall0159 Looks like more Wind and storage needed to get to 100% Solar not so much?
@MrLee I think we are hitting diminishing returns for solarPV in South Australia at the moment. Probably, as we get more storage, implement load-shifting (from the night into the day) and electrify more of the economy, there will be increased demand for daytime solar.
For example, if green hydrogen (to make green steel, green ammonia, green fertilizer) gets going, that could absorb a *lot* of daytime solar.
Also, the new inter-connector with NSW will greatly increase demand for South Australian renewables (currently, the connector to Victoria is only ~700MW, limiting how much electricity SA can export)
@wall0159 It will be interesting when EVs arrive in big numbers and when V2G becomes ubiquitous. In the UK, they have found that the middle of the day is the most popular time to charge an EV, so perhaps more solar will get used.
