The disgraceful farce is the promoters of 'green' energy who think we should live off this expensive rubbish while China won't have to go 'net zero' until 2060 (which they never will anyway).

Wind energy producing 400 MW and solar 99 MW this morning in South Australia - the problem is that we need 1040 MW right now. The remaining balance comes from good old reliable fossil fuels.

If only geothermal was made to work in outback SA.  That said, SA would be an ideal location for Nuclear Power IMO.

Geothermal was tried on a large scale at Innaminka about ten years ago and found to be un-viable as we simply don't have the right kind of volcanic activity here like Iceland or New Zealand - the Gillard government threw $88 million or so at developing it.

Molten salt nuclear technology is extremely reliable and safe - safer than 'green hydrogen'.

Renewables are cheaper than coal, nuclear, and gas, no doubt.

The issue is the lack of reliability with wind and solar.  Solar thermal, pumped hydro, and batteries can alleviate that, but then the cost goes up...

FACT: Would renewable energy be viable without the billions a year it gets from grid-captive users?

They're not cheaper, this is a falsehood perpetrated by the promoters like Simon Holmes a'Court and Malcolm Turnbull. They're only 'cheap' because they're extremely heavily subsidized by grid users who also pay for them to be connected to the grid.

A 2016 Senate report found each and every wind turbine was directly given half a million dollars every years from grid users.

That was 2016.  Much has changed since then.

If grid users use coal, last time I looked they still got a bill.

Yep, the RET has gone UP to $7 billion p/a (previously around $5.5 billion); that's way more than (for instance) the UK which directly subsidises wind farms to the tune of £1.5 billion p/a. Bear in mind that RET is just ONE tax out of many that consumers are paying towards the substitution of fossil fuels for unreliable wind power - up to 30% of your power bill is now 'network charges' where consumers are made to pay to connect these marginal sources of power to the grid. Alan Moran writing in the Australian 7/2/2021 says that we spend more per capita than any other nation on renewables - more than was being harvested from Gillard's carbon tax.

Wind farms get paid a base 'availability' rate regardless of whether they produce power or not.

Joe Biden has announced plans to build 30,000 MW of wind farms that will float on barges to be anchored off-shore in the Atlantic; the projected cost will double the price of power for the average consumer. From the New York Post:

Last week, the Biden administration announced “a bold set of actions” that it said will “catalyze” the installation of 30,000 megawatts of new offshore wind capacity by 2030. A White House fact sheet claimed the offshore push will create “good-paying union jobs” and “strengthen the domestic supply chain.” One problem: It didn’t contain a single mention of electricity prices or ratepayers...

...In February, the US Energy Information Administration reported that offshore wind continues to be one of the most expensive forms of electricity generation. The agency estimated that in 2026, producing one megawatt-hour of electricity from offshore wind projects will likely cost about $121. That’s nearly double the cost of generating that same amount of energy with an advanced nuclear reactor ($63) and more than three times the projected cost of producing it with natural gas ($37).

Take away the lucrative federal tax credits, and the EIA projects offshore wind could cost as much as $150 per megawatt-hour in 2026.

I'm curious as to how the barges will be anchored into position and how they will be attached to the grid - surely the most expensive part of the whole exercise?

Greta Thunberg has finally called out China as the world's largest carbon emitter and the country least likely to do anything about climate change - and the Chinese Communist Party hit back immediately calling her 'uneducated' and 'manipulated by political forces'. From Sky;

Ms Thunberg’s tweet which argued China has “no excuse” for its titanic emissions levels “ruining future and present living conditions” even if it is still classed as a “developing nation” served as the trigger for Beijing’s ire.

“Yes, China is still categorised as a developing nation by WTO, they manufacture a lot of our products and so on,” she said in the tweet.

“But that's of course no excuse for ruining future and present living conditions.

“We can't solve the climate crisis unless China drastically changes course.”

Her tweet came after a new report from the Rhodium Group found China’s annual emissions in 2019 eclipsed all developing countries combined – for the first time since measuring began.

And workers at coal fired power stations get paid 6 figures regardless whether the wholesale price is negative or not.

What's your point?

Except that the wind power doesn't work at times that it doesn't want to. Isn't it great - just like a CFMMEU member.

Probably to be replaced by more efficient models. In other parts of the world they would be salvaged for parts. However, in the USA, lets blow them up for the spectacle.

Sounds like a significant failure at Callide coal power station.  Looks like gas is being used to prop up supply.

You'd need either a huge crane or an industrial lift helicopter to dismantle it that way. The most valuable bits inside the turbine housing will be the 5 tonnes or so of scrap copper in each one and that's not going to be particularly compromised by slamming it into the ground.

To the credit of the windfarms that we have here in SA they've been doing exceptionally well in delivering power for SA for the last few days but we've had a fairly hefty rain system with accompanying high winds. So if they're going to work they'd better work now!

Dropping them on the ground is the easy bit. I'm sure the turbine owners would be resisting having to dig up and remove the enormous heavily reinforced concrete foundations.

The trip looks like to have knocked out other coal as well, at a guess the Supercritical ones that don't like major change (will check later), also likely Boyne Smelter was tripped to reduce the load by 1000 MW. Boyne also /well used to buy some small quantity of power from Callide.

Gas, hydro and import brought in but took a few hours to repair the damage to the grid stability, but Qld's very low import capability pretty much left the rest of the country un fazed sitting on $45/MWh while Qld peaked at $4500 /MWh.

Just knock the top off them so the desert can return to the surface and job done.
