Interesting how it's phrased as a bad thing. Article was probably sponsored by Big Coal.

Unfortunately it is a problem that needs solving. Electricity needs to be used as it is produced and if its not, it will be a problem. Where i live, the de facto solution today is to heat the oceans. That's not a viable long term solution and why we urgently need to find a way to store energy!

While that is true for power plants with spinning turbines, it isn't true for solar power. There is no issue at all when you don't consume all the energy that a solar panel could produce.

Please expand! Why is this not an issue with solar?

With spinning turbines, the issue is, that you need to maintain a constant speed of the turbine at all times. That rotation speed directly correlates with the mains frequency of the attached generator. That's either 50 or 60 Hz depending on where you live. If the load increases the frequency drops and the turbine speed decreases, when the load decreases, the opposite happens. The people maintaining the grid have to make sure load and supply are in balance to keep the frequency stable and the trubines within their operating parameters.

Compared to that, solar panels have none of these constraints. For one, they output DC voltage not AC, and secondly they don't mind at all when there is no or very little load. The DC voltage is electronically converted to AC by an inverter. Such an inverter synchronizes its frequency with the frequency of the power grid. So you can easily simply disconnect solar panels when there is too little demand without any issue. You can't easily do the same with a power plant with a turbine. If you were to remove the load from a turbine, you could actually destroy it, if you are not very careful.

New V2G will help, take it up through the day,. some discharge at night.

And this could be actioned

To be fair, WA by "natural" gas... /s

That fucking doublespeak clickbait headline, straight out of goddamned Orwell.

[-] veroxii@aussie.zone 26 points 2 days ago

This is a problem created by the suppliers who have kept jacking up prices. What else are people going to do? And the last few years they've upped the daily connection fee so you have to pay them regardless if you use energy or not.

Privatization was a huge mistake.. thanks LNP.

I uh... I wouldn't mind if they sent some of that struggle to my country, I think I could bear it.

Yes, I volunteer as tribute!

This seems like a good problem to have, no? Just need some batteries or some interruptible industrial processes to absorb the excess.

get the government to stop fuckin spiders, put a hybrid system on every house, job fuckin done, (i know it's harder then that but is it really?)

Plug in more electrical devices!! Buy a wall powered vibrator!
