Hello all, I built this for fun this year. It may be able to help: - reduce your carbon footprint, - eg. see the best time to charge your EV - eg. hook up a smart heating/cooling system? - learn more about how the renewables transition Currently limited to the Aus National Electricity Market, sorry... Feedback and questions appreciated!

This is so cool!! Where are you pulling all the data from? And how hard do you think this would be to implement on the US energy system?

From the article: "Every 2 hours, GreenForecast.au servers grab data from AEMO, a weather forecast and two other minor sources"

Thanks! There's one big energy market operator in Australia, they publish heaps of data but it's a pain to process [0][1].

I'm no expert in US energy... Presumably each of your (many) markets will have different available data, but more-or-less equivalent. Probably do-able, but will need to be re-done several times over!

This is super interesting! As an idea, would it be possible to get a totals of AEMO greenness/renewable?

Sorry, not quite sure what you mean? Do you mean displaying the total power output (aka total demand) in MW rather than as a percentage? (In case that's correct, it's an interesting idea, I've been going back and forth on it, how would that info be useful?)

Oh, that was unclear. Having a "Total" option next to the states. That way it would be possible to see the renewable percentage for the grid as a whole.
