Australia struggling with oversupply of solar power
(www.abc.net.au)
This is a most excellent place for technology news and articles.
What's also interesting to me is that we here in Utah used to (and maybe still do?) sell dirty electricity to CA (we produce a lot from coal and gas), because they didn't have sufficient base supply.
CA really needs effective base power supply, whether that's batteries or some other clean-ish energy source/storage solution. Meanwhile, electricity here in Utah is quite cheap at $0.12/kWh-ish, which is nice, and something like 1/3 of what CA charges.
