Yes, especially since the Greens are not going to determine energy policy any time soon. Even if they were it is not a realistic target. Still, there is nothing in the Greens' policy statement that as much as hints at fossil fuel based energy plants will be phased out faster than a base load capacity by other means can be established.pErvinalia wrote: ↑Thu May 16, 2019 10:57 amI think 100% by 2030 is possibly optimistic. But it should be possible to have a large majority (80-90%) by then, with the rest coming from liquid gas generators.
The advantage of the redox flow batteries is that they can be built to very large scale. You can increase the capacity by putting in more tanks containing electrolyte.Svartalf wrote: ↑Thu May 16, 2019 11:08 ammmmh, if what Rainbow posted is realistic, it looks like tech went along faster than I know, and that I may have put my hoot heep imma mouf...
I still fear power price may rise significantly due to the massive investments to recoup.
Do we know accurately the life span of a solar panel or wind turbine?
(ETA: The life spans of solar panel and wind turbines are as well known as those of coal and gas based electricity production plants.)Svartalf wrote: ↑Thu May 16, 2019 11:08 ammmmh, if what Rainbow posted is realistic, it looks like tech went along faster than I know, and that I may have put my hoot heep imma mouf...

They are only unrealistic about the timing - change is definitely happening, renewables plus storage are steadily becoming economically preferable as well as being vital in ameliorating climate change. Coal (aside from what's needed for smelting) is on the way out, and a grid serviced by a range of different renewable sources, with well-designed storage, should work very effectively. But it's not going to happen on their overoptimistic timetable.
