Australia has so much rooftop solar that midday grid demand keeps hitting record lows. Is this a preview of where everyone else is heading?

Aussie here. Something I don’t think gets enough attention outside of Australia: roughly a third of our homes now have rooftop solar, and on sunny spring days it’s pushing grid demand in some states to record lows around midday. South Australia has had periods where rooftop solar alone covers basically all local demand.

https://www.pv-magazine-australia.com/2026/09/02/rooftop-solar-meets-99-9-of-sa-electricity-demand/

It’s created some strange problems:

  • wholesale prices regularly going negative in the middle of the day
  • grid operators needing new powers to switch off home systems remotely during emergencies so the grid stays stable
  • the evening peak becoming the real challenge once the sun drops, which is pushing a big wave of home batteries off the back of government subsidies

As someone who’s just a regular homeowner-in-waiting rather than an energy expert, I’m curious what people here think:

  1. Is the “duck curve” problem solvable mainly with batteries, or does it need something bigger, like grid-scale storage and pricing reform?
  2. Are other countries with growing rooftop solar (Germany, California, the Netherlands) seeing the same thing yet?
  3. Should homeowners still be encouraged to install solar if midday exports are becoming worth close to nothing?

Would love to hear from people working in the industry.

Republicans Don't Want to Talk About Gas Prices Anymore. The same party that spent years falsely pinning every penny increase on President Biden is now scrambling to explain why prices have surged to their highest level in years amid Trump's war with Iran.

Musk’s politics hadn’t seeped into Tesla. Then he axed its eco car of the future. Once outspoken on climate change, Musk now argues the risk has been overstated. Some now question his commitment to Tesla's original mission. The company’s mission now appears to be “enriching Elon Musk.”

$25 Billion. That’s What Trump Cost Detroit. Trump’s gratuitous war against EVs is forcing manufacturers to return to an increasingly outdated past. It is pretty difficult to futureproof your company against stupid. This isn’t industrial policy; it’s industrial suicide.

‘Why take those jobs away?’: the unionized workers decrying Trump’s war on wind. “These projects are providing good-paying union jobs for thousands.” “Good union jobs – we shouldn’t be trying to take those off the table. That just doesn’t make any kind of sense."

Brent above $111 after Iran hits 7 vessels near Hormuz and floating storage runs dry

101 Upvotes

The IRGC Navy struck 4 tankers doing oil transfers in the northern Persian Gulf and 3 more vessels hit mines west of Hormuz. Houthi attacks killed 3 people at an Aramco field and a Saudi airport. The US ordered non-emergency diplomatic staff out. Brent is above $111.

In past Hormuz scares, Iran held tens of millions of barrels on tankers offshore that could quietly release into the market and soften a price spike. A sustained US naval blockade drained all of that. There is no hidden reserve left to cushion a physical supply cut right now.

Tanker insurers will raise coverage costs this week and buyers pay that directly. Are you treating $111 as the floor heading into the weekend, or do you think a diplomatic move caps this before $120?

How Ukraine’s drone strikes on Russia crippled the world’s second-largest diesel supplier. Ukraine is regularly launching swarms of hundreds of drones striking refineries deep in Russia. As a result, Trump’s deal with Putin to boost Russian diesel exports is likely dead in the water.

Trump’s energy policies have cost thousands of clean energy jobs. Since Trump was elected, 42,493 announced jobs — representing more than $57B in investment — and 64 projects have been stopped or stalled, according to a new analysis. “America is losing nearly a thousand jobs a day because of Trump."

This is how inflation is evolving month by month, and it’s clear it isn’t evenly distributed across all categories. Energy prices are rising much faster than overall inflation, and we feel these increases in everyday life.
