Modern nuclear reactors used to be huge, but that’s outdated now. The revolution in small modular reactors promises to change all that.

Current modern nuclear reactors getting built are huge.

Maybe, perhaps, in the next decade or two we'll see small(er) reactors, but this isn't a new idea and hasn't worked out it practice before.

Nice article explaining solar energy policy. I think the article still doesn't address the mismatch between solar energy production and consumption, which needs to be filled by storage mechanisms. Also would have been nice to have a critical look at how the Chinese were able to corner the Solar market via state sponsored means.

What "critical look" is there to take? How about the way that the US gov't subsidizes the oil and gas industry, and is about to restart the coal industry? For some reason gov't investment in industry is only bad when China does it.

Nobody complains about China investing in its private industry, all wealthy nations do that. Everybody complains that China is a dictatorship that a) treats its people like shit, b) exploits these shitty conditions to gain global market advantage with state-owned companies, and c) keeps foreign companies from exploiting it, too.

Obviously it is more complex than that, but in a nutshell it's part butt-hurt and part amalgamation of state and private enterprise that does not mesh well with classic liberal ideas of freedom and human dignity.

good article I just don't know why author prefer to spell all numbers using words rather than digits. It's very mentally taxing for me to read, e.g: >> of twenty-one thousand respondents in twenty-one countries, found that sixty-eight per cent favored solar energy, “five times more [...] could be just: >> of 21,000 responders in 21 countries, found that 68% favored solar energy, "5x more [...]

I believe this is a New Yorker magazine house style thing. I'd assume the author uses numerals in the book this article is based on.

If there are two options, you can trust they'll go for the more verbose one.

One of the good things about solar is the lack of a mismatch between solar production curve and human needs.

People use more energy during the day.

People, globally, use more energy in the summer.

This might not be intuitive if you live nearer the poles, but that's not representative of where the global population live.

And in some of those places, like California people obsesses about the "peak" that is left after you subtract all the solar energy, even if it's lower than the previous real peak.

Luckily that fake peak is immediately after sunset and so easily beaten with a small amount of battery, leaving a much cheaper and easier problem to solve as the peaks are really what drives electricity costs, dictating transmission size and standby capacity.

Do you have any source for this extraordinary claim? It's practically a claim of perpetual motion. Carbon dioxide a tiny fraction of the atmosphere, even in concentrations which are immediately harmful to human life. At the moment it's 400 parts per million. So in order to extract 1kg of Carbon Dioxide from the atmosphere you have to pump 2500kg of air through the system. This alone makes it unlikely we can do this p…

They said "If electricity is sufficiently cheap", which is less a claim and more a tautology. Will it be that cheap? I think so, given that trees and grass etc. exist and get their carbon from the air.

Even with free electricity, the capital (and maintenance, consumables etc) costs of the process could easily be too high.

I’m all for solar - but does it really solve the geographical / geopolitical issues of oil, as it’s currently rolling out?

China produces pretty much all the solar panels - That’s quite a big concentration of power, even more so than oil.

I suppose that in principle that is indeed possible; in practice, trees exist and self-seed, so the limit is our own ignorance.

Solar panels can be locally recycled. Oil cannot.

Of course if you don't build up a local solar industry you are still dependent on foreign countries but it's not that China has an unchanging monopoly on the solar industry.
