"Hydraulic fracturing, or fracking, was developed in the 1990s to extract natural gas from previously inaccessible shale deposits.1"
Hydraulic fracturing was developed in the 1940s primarily to bypass wellbore damage. It was first performed around 1948 in the Kansas Hugoton field by Pan American Petroleum. Funny how overnight success often requires decades of slow progress.
I would love to cross-post this article onto my Substack column. It seems that your articles do not have the "Cross-post" button. My guess is that this is because of your settings.

Thank you for footnote 1! That is absolutely the sort of thing that someone trying to learn more about a subject will miss, and similar issues have confounded me on other subjects.
Thanks a lot for this excellent overview - it was well overdue for me to learn some basics on this fascinating and critical technology that contributed so much to reducing emission and harmful geopolitical dependencies.
On scaling up deep geothermal: there's only 40 TW of natural geothermal flux and we need some 10 TW for current civilisation, perhaps double that accounting for progress in currently poor regions. So betting on deep geothermal to get much of our energy needs takes us in a uncomfortable range of significantly changing a geophysical flux. (Recall that the whole human-induced climate change is just from modifying some 2% of the solar heat flux).
Source of figures: this excellent paper form Axel Kleidon of the Max Planck:
If this is true, then reducing the geothermal heat should be a positive offset to reduce atmospheric and oceanic warming. Well before the time geothermal is a significant energy source, we will have much more knowledge of its side effects.
Interesting point Buzen, but the numbers wouldn't work out. Wish I could paste that figure from Kleidon's paper. Solar influx is some 10^5 TW, our change to it through greenhouse gas is some 1-2% of that, ~10^3 TW, so even if double the 40TW of natural heat flow from below, it would only be a few % of the human-induced forcing. The side effects on a such a complex and non-linear system cannot be predicted. The tail risk is just not worth it - better to focus on developing other technologies such as solar, storage, transmission and demand-response, which fortunately, are also cheaper and more mature.

Fracking and vapes are some of the most important and underrated innovations of the last few decades.
A very nice overview of one of the greatest technological revolutions of the 21st century.

If I'm not mistaken the reason geothermal energy is viable is the low cost.
Will it remain low cost using fracture methods.
How much energy is used to produce the geothermalfrackenergy GTFE ?
Thx
