I need some clarification, please. I have a home geothermal system, 7 wells were dug. Why is fracking necessary large scale? To power electrical plants? Thanks.

There’s a difference between the twenty foot wells dug for residential purposes and the deep well required to provide steam to power plants. Geothermal for heating a house is different than the requirements to spin a turbine for electricity

Hmm... I still don't understand where fracking is an issue. Deeper reach for aquifers may have issues especially with cost, but I'm not understanding where fracking enters the equation. Thanks.

The Geo Thermal systems for steam generation to power turbines go miles deep into rock. Fracking is used to crack the rock to provide the surface area into which fluid is pumped to down into the fractured rock and then returned back to the surface under pressure to drive the turbines. I’ll look for a link

Thanks. I haven't found any reference to fracking.

This is strange. Substack won’t let me paste the links. Google “geothermal energy fracking” . Find the Scientific American article

I read both 2013 articles, were these to which you refer? They describe quite an enhanced version of geothermal.

"Fracking “enhances” geothermal by making cracks in hot rocks where none existed, allowing heat to be harvested from Earth’s interior practically anywhere, although this reduces the total power produced because of the need to pump water through the system."

I'm seeing two different sources of geothermal heat. Core drilling vs. aquifer. Thank you, it's always a good day when you learn something new!

Here’s one, but in general,deep well geothermal needs to crack rock at the bottom of wells to create the surface area of the exposed cracked rock to heat the fluids that run through the heat exchanger to create steam

Opps, link wont post. I’ll try again
