Like trying to assess the economy of the Third Reich while omitting that whole pesky war thing

I wonder why existing hydro isn't utilized to it's potential. For instance, the Grand Coulee Dam has the highest capacity of any power station in the US of almost 7 MW but usually puts out about a third of that.

Niagra falls doesn't run at full capacity because it takes away from the attraction of the falls themselves, and tourism is important there. They turn up capacity after hours, and the falls slow down.

Not only that, they use the gravitational potential of the falls to store massive amounts of energy when there's a surplus. Way cheaper to hold or even pump the water back up to the reservoir at the top than build lithium batteries. So yeah, as a local, can confirm they turn Niagara Falls (partially) off at night. Thanks to the Falls and several nuclear plants on Lake Ontario, Upstate NY and Southern Ontario have some of the lowest carbon electricity in the countries. Quebec is even better with basically all of their power coming from hydro.

They are used as dispatchable sources. Capture value by being able to provide enormous amounts of power when needed compared to the watershed flow.

Kind of a weird headline. It makes it sound like this just happened. But it happened almost 2 years ago. Reading the article is also a bit confusing. I finally figured out they are only referring to utility scale solar and not total solar (utility plus behind the meter)

That entire talk didn't once mention the phrase "energy density" which is the real reason we rely so heavily on hydrocarbons. Additionally this talk makes the usual mistake of conflating "electricity" with "energy". While the US does have fairly high percentage of energy in the form of electricity it's still only around 33% of the US energy needs. And still we see that "green energy" only supplements not replaces our…

He talks about transport and heating

That doesn't leave much left when you look at the energy flow once you remove domestic, commercial and transportation usage and replace it with electricity. A tiny amount left for plane s(and reducing per flight as planes get more efficent and battery planes start coming to market), and industrial gas usage.

> if you exclude the enslaved, the south had a higher GDP per capita than the north. That doesn't tell the whole story though. If you own 100 slaves, you need to spend nonzero resources maintaining them, or else they will starve and then you have zero slaves. So the owner has less wealth than the equivalent person in the North that has the same income but zero slaves. You can't directly compare GDP per capita excludi…

Except that slaves also make new slaves that can be sold.

I really dislike this idea that slavery was just a cultural aberration and not economic. For one thing, that lightens the moral stain of slavery adjacent activity, most notably colonialism and the exploitation of the colonies. This never went away. Economic colonialism exists to this day. We just call it “outsourcing”, “offshoring” and “subcontracting”.

Lake Powell behind Glen Canyon Dam is currently at 23.6% of capacity. Lake Mead behind Hoover Dam is currently at 29.7% of capacity.

Given the current state of the Upper Colorado River basin snow pack, there is a not-insignificant chance that Lake Powell will recede below a minimum power generating level by the end of this year for the first time ever.

He has a whole video[0] on the difference between energy and electricity, so he understands it. Maybe there's some disconnect between the video and your interpretation. [0] https://www.youtube.com/watch?v=OOK5xkFijPc

Arguably that's honestly worse since he knew and was disingenuous in order to push a perspective that isn't valid.

I am reminded by the perhaps revisionist history but still applicable belief that slavery was really ended by industrialization making abolition economically advantageous and not actually a socially driven movement. (In reality it was certainly a convoluted mixture of the two I'm sure.) I hope we are in a similar era with regards to climate change. Surely there's a lot of money to be made in harnessing effectively un…

> Democracy has unfortunate failure scenarios, make a note for history books and system design lessons. Vote better next time. Major problems with the US system have been known for a long time. It's been regarded as basically obsolete for over a century now, by the kind of people who study this stuff.

What is considered the best* system of government? Which country comes closest to the ideal model? *best is funny to define

I guess the answer has to depend on demographics. But if we are spitballing, it probably wouldn't be all bad for every country to have a Lee Kuan Yew.
