If it was viable it would have happened already. We have a massive oversupply of solar and wind, particularly on the west coast. Generation is the easy part.
We have terrible storage and transmission, the parts that are actually expensive.

It is happening, all over the world, with a persistent and rapid growth curve.

Better cut those tariffs on cheap Chinese batteries (and aluminium for the transmission).
Not that anyone would build one in the current political reality, but China produces enough aluminium that it would be viable to make a genuinely planet-spanning 1Ω power grid connecting your midwinter nights to someone else's midsummer days.
Renewable generation is not the hard part. Renewable transmission and storage is the hard part. Its so hard, in fact, that building very expensive nuke is still much cheaper and more attainable.
> So nuclear plants, by and large, get the market price whenever they produce (which is most of the time) and this does not equal the average price as they will be producing a higher share of total production at times of low demand (and low prices), and a smaller share of total production at times of high demand (and high prices).
The assumption here is that the price is set by only demand rather than the combination of supply and demand. Under that false assumption, generating power when demand is lower (i.e. at night) is bad. But how much solar generation is there at night, and what does that change in supply do to prices if you make solar a higher percentage of the grid?
It does the oppose of this:
> whilst the capture price for solar is often higher than the average price (thanks to power demand generally being higher during the day)
Because solar generates only during the day, in order to supply power with solar at night, you would need it to oversupply power during the day and then pay extra for storage to resolve the undersupply it leaves at night. So once you have a certain amount of solar, you end up with lower prices during the day, when solar is generating a higher proportion of the power, and higher prices after sunset.
And solar is double screwed by this. Not only does it get the soon-to-be-lower daytime prices for all of its output rather than half, its output is further regionally correlated, so that on sunny days when its output is highest, even the daytime price is lower than it is on cloudy days, because higher or lower solar output is a cause of lower or higher prices, i.e. the daytime price anti-correlates with its output.
The #1 rule of HN that must never be violated: software developers are the smartest people on earth, and literally every field could benefit from their definitely not stunningly overconfident and reductionist contributions. I dread threads about engineering subjects I get paid to be competent in because I can't handle the tsunami of neckbeard opinions that I'm about to see.
Of course all governments want to control every move and thought of their citizens. It makes governing easier. We expect that in autocracies.
I don't know about The West as a bloc, but at least the USA was supposed to have respect for the basic individualistic privacy and freedom of the average citizen. We've allowed that to largely evaporate. The differences between the US and something like the PRC are rapidly eroding.
Don't get me wrong, the US is still an order of magnitude more free but you can see a future where the trend lines are converging.
I suspect there are a lot of American hegemony trends that look like this. The US is burning good will and soft power that took centuries to accumulate in days or hours. This was a long term trend but the current American government is really stepping on the gas.
The american century is over, but I'm not sure what comes next will be better, we will see.
Let me just quickly use absurdism to illustrate why argument by analogy is weak (and unfortunately overused on HN):
“””
Humanity has been using celibacy for over a millenia, however it's only in the past 100 years or so we have a good understanding of not having sex affects the psychology of a person, turning them into an ubermensch. Based on this argument, we should have never stopped having sex, until we had a complete first principles understanding.
“””
Analogies can produce a lot of words, making it appear to be a high effort comment, but it also shifts the argument to why or why not an analogy is good or not, and away from the points the original poster was trying to make. And, by Sturgeon’s Law, most analogies are utter crap on top of being an already weak way to form an argument.
In my life I’ve come across a few people who are really good at making analogies and it’s wonderful and makes mine look like a child’s scribble next to a Monet.
In fact, I think analogies are some of the most powerful rhetorical devices and, unsurprisingly, one of the most difficult to master.
Look at some of the all time, almost supernaturally skilled, analogists: Jesus, Plato, Buddha, Aesop, Socrates. Their analogies will be eternal.
Now that said, we aren’t always seeing quite that level of skill often here on HN (or anywhere) but when you see a great analogy, it’s like…[scratch that, I’m resisting the urge to force an analogy here].

So when we consider school spending it's important to count every penny but when we consider military spending we can just neglect vast swathes of spending?
