Yep, no change

So how's the Murdoch greenwashing announcement going?:


I do have to say, though, regarding the European and Chinese energy shortages:   I have never really understood how cold climate countries can show that they are really serious about zero carbon emissions (without nuclear) until they come up with the plan for dealing with their freezing winters with renewable energy.   I mean, years ago, I was saying that it seemed odd for a cloudy winter country like Germany to be putting too much reliance on home solar.   Sure, it might work well enough for half the year, but be of pretty limited utility for the part of the year where energy is really needed just to keep warm.

As I too am still not keen on nuclear, I suspect that, apart from extra wind power (which does not always work in winters), the only path forward for these countries to be a combination of long distance transmission of solar power (turn a few arid countries in North Africa into giant solar farms with cables running into Europe - it's not like they're doing anything very useful with the land anyway), plus utility scale storage.  I think - just a hunch - that flow batteries may be the way to go there - maybe some in the African countries itself, and some in Europe.

As for Australia - we can do the same, but on smaller scale, since not that much of the country gets that cold.   Still, we have the natural advantage of a northern part of the country enjoying dry, sunny winters,  which could supply winter power to the colder, cloudy winter parts of the country.   And, to a degree, vice versa in summer.

I think there is also much greater scope in Australia for domestic scale batteries - really, I don't see why the government just doesn't mandate home scale storage in all new house builds.  Economy of scale, you know.

  1. yeah it aint too hard to figure out what was the problem in the UK. GAS but somehow it is ignored.

    i'm shocked
