You can't get the battery rebate unless you have PV 😀

But the economics and solar rebate setup are such that the extra cost of PV is very modest... can take advantage of batteries with DC solar inputs.

Saw one supplier offer unlimited free solar with every battery purchase!

Prepaid meters are indeed completely fucked and an insult to first nations communities

24. We oughtta be building more wind. Seriously, solar will get built anyway, but wind needs some help, and wind blows in the dark and in the winter. It doesn’t help that solar pushes down power prices and generates renewable energy credits (where relevant), which hurts wind farm economics.

5. Solar modules now cost 8.9 US cents per Watt (higher in US, India due to trade barriers). Solar panels are cheaper than ordinary fencing materials. For rooftop installs, non-module cost is still $0.50-3.00 per Watt, so further module price declines make little difference.

There's a rare earth mine being developed on the other side of the state from me in Australia, and locals were pretty annoyed to find out "oh yeah, we'll be producing uranium concentrate too..."

Yes, I assumed you're not just there for the catering.

Interesting! Heat loss surveys are essentially unheard of here in Australia except for very high spec builds perhaps.

In practice it means things are usually way oversized. It's not great, but installers figure complaints about undersizing are worse...

Do they propose+build any of their own network though? I thought theirs was all managed on behalf of others unlike Evie.

Looked into how much compute they use for seismic mapping? 😬
