Many Australian politicians and much of the Aussie media seem against solar energy.

I saw the Australian news complaining about power outages, then arguing against solar energy specifically. "When the sun goes down, solar stops and that's when people need it."

For one thing, the sun sets at 8:04 pm tonight in Sydney.

II would have thought that Australia would be an ideal case for solar uptake everywhere, with government subsidies for solar instead of coal.

In summer the power curve must be high demand during daylight hours for air conditioning.

For homes, a simple timer would start the air conditioners perhaps an hour before the occupants arrived.

May I wrong?

Yes, its great for summer  but....

 

The biggest problem is in Autumn and Spring when there is still plenty of sun, but not much A/C load, and it starts to disrupt the existing baseload,

The problem is that batteries are not cheap....and generally make the economics unworkable for many people,

 

Panels on the other hand are a cheap was to lower your own power bill,

True. Must admit though should have mentioned was talking more about large scale - focused onto towers and molten salts, etc

Funny, that’s what I was thinking. Doesn’t South Australia have the biggest battery?........And the highest power prices in Australia.

How hard is it to turn the market completely dynamic in terms of minute by minute power prices? Even negative power prices so if people feed into the grid during bad times they literally need to pay? Would be an incentive to make a "smart" network.

I know some people don't like Jacinda, but imagine if we had a neanderthal like Morrison as PM.

He'd be thrilled if every Aussie home had a Victorian cast iron stove using coal.

The Tesla battery farm has been an outstanding success.

I met lots of people from the Oz power industry on a course recently.

 

Solar is such a big thing that they have coal power stations shutting down *every* weekend. This is compared to a 'normal' thermal plant shutting down every ~10 years.

 

There's also pumped hydro projects and wind going ahead.

 

I know we think of oz as a coal loving place but there's panels *everywhere* in QLD. I was told there's so much solar etc. coming on stream the prediction is certain coal power stations will be brought to EOL 20 years early.

 

But yeah, look at the state of Oz, they're 40 years late.

Lived in Aussie for 30 years and my partner & I could never understand the lack of any federal or state SERIOUSLY REAL push for a solar industry considering the amount of effective solar hours there is. Yes I know there was and still is, lots of half hearted attempts by various governments to kick start something but it has never been really serious. It was mostly just election gimmicks.

 

WHY - because of the fossil fuel mining and power industry lobbyists.

 

The mining sector’s power to influence Australian politics is infamous. Experts and environmentalists say the industry’s power is derived from political donations, gifts, advertising, paid lobbyists, frequent access and close political networks. All these mining multinationals have run sophisticated operations to kill off climate action in Australia and they continue to wield day-to-day influence over federal and state governments. The Rudd government even tried to introduce a mining supertax, well we know how that ended - bye bye Rudd government.

 

Until Australia has strong politicians with a real strong public mandate to rein in the mining and power industry there will be no meaningful action on reducing greenhouse gas emissions and the introduction of any real climate changing policies in Australia.

You forgot to include the number of people directly and indirectly employed by mining as an influencing factor as well.

According to this, Mining and oil/gas earnt Australia $280 Billion in 2018/19, it was around 50% of total exports and employed 250,000 people

 

it was around 8% of GDP.

 

https://publications.industry.gov.au/publications/resourcesandenergyquarterlymarch2019/documents/Resources-and-Energy-Quarterly-March-2019.pdf

 

But what's impressive is 280 billion over 250K people is around $1 million in exports per person....
