Drivesafe I was joking JOKING!! Coal fired power stations will still be going decades from now. Look in NSW some CZeck investors have just bought Vales Point and Isn't there a bid from a Canadian group for AGL?
Thye obviously don't think that they are "stranded assets" . what ajoke that the NSw Government sold Vales Point for $1 million and the buyers are now selling it for $170 million.
Tim Flannery should be sued .

Mean while in WA[bigwhistle][bigwhistle][bigwhistle]

This is interesting "Across the globe, governments and developers are pouring hundreds of billions of dollars into large offshore wind farms like Beatrice to meet climate-change goals.





These initiatives are attractive to investors and lawmakers because they produce enormous amounts of clean energy and can be placed far enough from shore that they are largely out of sight. Britain is already generating more than 10 percent of its electricity from wind at sea, and on some gusty days, like Nov. 2, wind produces more than half. "

"Beatrice has 84 arrayed over 50 square miles of blue water" LINK NYT

Out of site is not in my view perfect. Why is so much money pouring in to wind! "Beatrice also makes a load of money. In the year that ended on March 31, it recorded an operating profit of £218 million on total revenues of £393 million — or about £1 of operating profit for every £2 of revenue."

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ yet issue is they are at best capable most of the time- the other times are needed and the diversion of funds to wind for the $$$$ means the other times are costly and more difficult than they should be. AGL Gas fired plant in South Australia might be an example?

We need more power - Love wind- it cannot replace or more importantly provide what will be needed. Arena on Aluminium is interesting to watch. They also plan to add a LOT of hydrogen to that process which IF from Pyrolysis would use a LOT of eletricity as well.

Noting spare excess to hydrogen electrolysis should be here soon as well rather than turning off wind generation as happens often at night and weekends now.

Yeah, I have no issue with it - more is needed and in a hurry. They will be using 12 or 18MW turbines - they are MASSIVE! Incredible advancement in output over the last 10 years. I remember when 70 metre towers/3MW units were considered giants only a few years ago, now they are babies... [thumbsupbig]

Despite the huge on and offshore wind energy added to the UK low wind has made it very very messy today! they just cancelled brown outs!
Emergency energy plan not going ahead on Tuesday - BBC News
"National Grid had been ready to trigger the scheme following a warning that Britain's energy supplies were looking tighter than usual this week.


However, it decided that the measure was not required.


Alerts are sent out automatically when expected supplies drop below a certain level. But they do not mean that blackouts are likely, or that the situation is critical.



"
Wind variability does not make stability.


Wind growth is very welcome. With out massive storage its is still a limiting factor . When I mean massive I mean grid scale suppy for about a week. No way batteries are going to do that ever!

Batteries are needed for grid stabilization with solar and wind! At that scale it is possible happily.

" the case of large-scale electricity supply-demand systems in regions with high solar and/or high wind resources that could drive the transition to 100% renewable electricity either within these regions or economical transmission distance from these regions. In these regions, variable renewable energy (VRE) such as wind and/or solar provides the major proportion of annual electricity generation. These regions include, on-shore, most of Australia, south-west and central USA, north-west China, north-west South America, North Africa, and the Middle East; they also include off-shore northern Europe and north-eastern USA, which have high wind energy resources. Together these regions have the capacity to supply a large fraction of global electricity from wind and solar photovoltaics (PV) by transmission lines
"

The missing bit is "EROI of renewables must be evaluated in a realistic way" Paywall sorry- EROI = Energy Output : Energy Used to Deliver that Energy

With most/some of the time Wind and Solar power, storage to cover the rest of the time has to be included in the real cost.

Flooding the market some/most of the time does not make a secure grid anywhere. The costs are very clear I think[thumbsupbig]

I find economics far more interesting than politics

Watching power/energy supply prices is interesting.

BASF permanently moving some parts of its huge business out of the EU is possibly the first large economic impact.

It is relatively easy to see where blind biased hope meets economic realty. Hope we do not stuff it up myself does of course intersect with political of course- not meaning to be political [biggrin]
